hi guys. I can't find a clear answer to this on google so I hope it's appropriate here. I've got a HP all in one that takes a barrel jack for power. looking up its model number it says it needs 65 watts. I can't find the original power adapter but there's a 45 watt adapter in the house for a HP laptop. I'm no electrical engineer, i just want to ask what would happen, would it not power on because the wattage is lower than it needs? or would it operate sort of undervolted? if it tries to draw 65w through the 45w adapter will it overload and damage itself?

I just ordered a Xeon e5-2699 V3 machinist motherboard and 32gb DDR4 ram but.. with my current Gpu it takes 518W and I have a 650w psu Will that be Enough headroom? (I don't currently have the money for a New psu and yes I do have Experience with Xeons for gaming) -
When upgrading, I got myself motherboard GIGABYTE B660 GAMING X DDR4 (https://www.gigabyte.com/Motherboard/B660-GAMING-X-DDR4-rev-10#kf). The board is OK, currently acomodating i5 12400F. After some daily use, I have several questions regarding RAM, CPU wattage and m2/nvme drives, and unfortunately google and even official documentation from Gigabyte failed to satisfy them, so I am turning to you guys, in hopes that someone already had same problems/questions in past and can help me. Problem no.1 - RAM frequency I purchased and am using 16GB (2x8gb) kit of RAM (Kingston FURY 16 GB KIT DDR4 3200 MHz CL16 Beast Black (KF432C16BBK2/16). I chose this RAM because it has official support according to the manufacturer, and it was very reasonably priced. HOWEVER, what manufacturer or any documentation fails to mention, is that this board only supports/can run this specific RAM on its base frequency of 2400mhz, setting it any higher results in black screen and PC starting up only to shut down after few seconds, only to repeat the process until I reset bios. I only learned about this problem AFTER purchase, I wasn't even aware such thing is possible, to have official support, but not for motherboards and memory's full advertised speed. My question - can anyone recommend me from their own experience a 2x8 / 2x16 kit of RAM that will work on at least 3200mhz with my board? Apparently, official list of supported RAM modules is useless in this regard (google shows other people with same problem on same hardware, but no solutions). Problem no.2 - multiple M2/Nvme Drives When upgrading, I put Samsung 980 500 GB drive in the motherboard, in the heatsink-covered slot (one closest to the CPU), and it replaced SATA SSD, and it looks really nice without one extra cable and works like a charm. Many people claim, that putting m2 drive in motherboard will disable several SATA ports. My question - can I get another, 1TB m2 drive, and would the PCIE 4,0 be able to handle two m2 drives, and how many SATA ports would that disable? The board have 3 m2 slots, but I am worried even 2 drives might be pushing it... Problem no.3 - CPU wattage for CPU upgrade I am considering buying i7 12700KF. I am well aware, that my board most likely does not support overclocking, and that's fine, I never OC'd CPU in my life, and am not about to start now. I just like the extra cores/e-cores and significantly higher base frequency. My question - even when not overclocked, the 12700KF can still potentially be power-hungry. Would my board be able to supply it with enough power to work properly without any risk of any kind of damage to the motherboard, assuming the CPU will not be overclocked (not like board would let me anyway). According to Intel, turbo power is 150W, but some people reported 190W when using it. I already have proper cooler for that wattage, it is the motherboard I am concerned about, as I have not experience with unlocked parts. Thanks in advance for any anwsers/advice. ^^ -
Hey all, I just got a new EVGA GeForce RTX 3070 Ti FTW3 ULTRA GAMING (which I haven't installed yet) and according to the EVGA website, it mentions a minimum 750W PSU is required. Using PCPartPicker, I've created my build with the new video card and all the remaining parts, including the Seasonic FOCUS GX-650, 650W 80+ Gold. According to that, the build consumes 515W plus 23W of the water pump that wasn't included (538W total), so why a 750W PSU is required? Should my 650W PSU be enough?

How to get more mileage (wattage) out of my build
ThankGodItsFriday posted a topic in Power Supplies
Hey guys! New guy here, although I've been casually following your vids for about a year now. If you'll examine my specs on my profile, I have an 850w PSU, and through a wattage calculator (on NewEgg), I got an estimate of 700w max for all my hardware. Yet, when benchmarking or using 3D modeling software, I rarely push anywhere above 350w. I don't know if my computer is running as efficiently as it should, or if that's a normal readout. Thought I'd throw this question out to you guys: Is this normal? Also, I'm not sure if I posted in the right place, because I'm new here. Be patient with me LTT! -
I currently have a system with the specs: AMD R9 7950X NOCTUA NH-D15 CHROMAX MSI MEG X670E ACE G.SKILL NEO DDR5 6000Mhz CL30 64GB NO RGB SAMSUNG 990 PRO 2TB * 3 GIGABYTE AORUS XTREME WATERFORCE RTX 4090 SEASONIC PRIME PX-1600 ATX 3.0 NOCTUA A14 PWM * 5 In a case: Phanteks Enthoo pro 2. One of the reasons for purchasing this case was the size which allows me to put in more hard drives and even a second system. However now, a year later I am planning on putting in a second system in the case but I recently found a little caveat. The case supports a second PSU OR a second system. Not both at the same time. The planned specs of the second system are similar to the first. This means both systems would have to run off of one PSU and I doubt the 1600W PSU is enough. My limited knowledge tells me that I need to look for a 2400W PSU with the size factor of the PRIME. Is my thinking correct and furthermore which PSU offers such specs?

I've posted this on reddit a couple times, but I don't get any help over it on there, I really need some help with this. Recently I've started to see a problem with my games and that is the frame times spiking exactly every second. It wasn't a problem before, it just started happening out of nowhere. I've noticed that every time it happens my wattage also jumps up and down, going from 50 to 100+ then back down or 70 - 100+ then back down. I've stress tested my GPU on furmark, and everything seems fine, no artifacts, still even during the furmark test, this was happening. I get 60fps in most games I play, but have this frame time problem at the same time When I lock to 30 it works fine. Recently lighting struck near my house and two of my WiFi routers got fried, ever since then, when I boot up a really intensive game, my pc just crashes, no display, nothing, just the GPU fans going crazy. What's giving out? Is it my PSU? My GPU? Or my motherboard? My specs: MSI twin frozr Rx 480 4gb Intel core i5 6400 Biostar Z270GTN 12 GB ADATA Ram (4+8) Thunder TGS - 550G (I've heard it's some local shady power supply with false advertising, I was on a budget at the time, so the computer store guy hooked me up with this)

Hi, Here is my comp-list: cpu: i5-12600k mobo: Asus Rog strix b660-i gpu: rog strix 2060 S ssd (OS): samsung 980GB 970 m.2 ssd: samsung 870 EVO psu: Cooler master V750 SFX Gold Rev.2 chassi: NR200P cooling: H100 240mm rad with total of 4 120mm fans in chassi. (Cooling is no issue) So here is the issue: I just swaped out my GPU to a Asus Rog Strix RTX 3080 TI and now i run in to all sorts of problem. If i unplug the gpu i can use integrated graphics so the computer works fine. But when i plug in the gpu everything goes to hell. No video, no boot device, video thru cpu but it freezes after 5s of usage. When i use integrated grsphics i can clearly see the gpu, it is detected and no errors. But as soon as i change cable from integrated to the 3080 all cinds of issues appear. So my question is. Is this a bad gpu? Or is my power supply simply to weak? The CPU goes up to 80W during boot. please help.

Just asking to make sure. I assume it’s okay if I have a cooler master 650W gold 80+ psu and pcpartpicker says my pc’s estimated wattage is 519W (with absolutely every components). (I did the math myself with all components wattage and it came out to about 540W max) Just trying to see if i can run all the fans I want in my new case setup. I am not wanting buy another psu since I recently purchased the one I have.

I am buying a UPS battery for my rig, I have a 7800x3d, 4090 FE, 64 gb ddr5, MSI Carbon MPG x670e, Corsair H150i pro 360mm, Corsair RMx1200w psu. According to PC part picker it says the maximum wattage will be 785W under maximum load. Considering the maximum load would be 785W would it be safe to use this battery despite my PSU being 1200W? As long as it doesn’t draw more than 1000W, it should all be good? I also plan on connecting a 42W monitor to the UPS and do not plan to OC my PC. I would appreciate if someone with expertise in this field would educate me. I would go for a 1500W UPS but unfortunately they are very expensive and all sold out right now. This is the UPS in question that I am looking at: CyberPower CP1500PFCLCD PFC Sinewave UPS System, 1500VA/1000W, 12 Outlets, AVR, Mini Tower https://a.co/d/1U9EuZP Any answers would be appreciated, thank you for reading. -
So, a friend asked me to find UPS for his system. Rough worst case estimate of power usage for that system should be 500W, so with PF of 0.6(everyone likes this number) a UPS above 830 VA should be enough. But I want to understand this better. His sys specs intel 13400 6750xt DDR 4 ram, 8GB x 2 1tb crucial p3 corsair RM850e 27" QHD 165hz monitor, have to ask for model number. dont remember motherboard model or make so now my doubt is what are the power factor for each of those components. Main power consuming components are CPU, GPU and then monitor. So if we account for them it is enough right? I asked google bard for PF values for CPU and GPU and it tells me that they should be 0.85 - 0.95 for intel CPU, Nvidia GPU and 0.8 - 0.9 for AMD cpu and gpu. Are these values correct and what about monitor PF. Modern power supplies also comes with PFC( power factor correction circuits).so, Another question is since PSU have PFC circuits, does it even matter what the components PF values are since they are dealt with in PSU and all that matters is PSU efficiency? If not then should we first calculated total power for CPU, GPU and then multiply with PSU efficiency to get final system power? and why does UPS makers assume 0.6 as power factor, I mean they give rated power in Watts so low compared to rated power in VA.

Introduction: By the popular concept of @Aniallation, who since retired from the forum, the "How many watts do I need" is still one of the most asked question by many people wanting to build a PC. By similar methodology, here a simple guideline to how much your PC would need, assuming the quality of the PSU itself is good. These numbers are estimations based off a stress maximum load, one you will likely never reach in normal use. Take these numbers as a guideline, but feel free to ask on the forum itself if you're still not sure what you need with your exact configuration. Methodology: CPU+GPU+50=estimated wattage, chosen worst case out of the configs Low-end APU system: Midrange APU system: Low-end gaming: Midrange gaming: Mid-high gaming: High-end gaming: High-end 3080 gaming: High-End 3090 gaming: Low-end hedt/tr: Midrange hedt/tr: High-end hedt/tr: Ultra high-end hedt/tr: CPU power consumption: GPU Power Consumption: License- 139 replies

Back-info: I recently upgraded from the I5 4460 to a R5 3600 and with it I also bought the Thermalright AX120. I let the motherboard, MSI B450-a Pro Max, do the overclocking on the CPU with the OC Genie 4 cause I'm a newbie when it comes to overclocking CPUs. (I have experience overclocking GPUs) It's running at 4.2Ghz. Ok so, since I had this new cooler, I wanted to test if would be able to cool the cpu while running Prime95. And to be fair it did pretty good (65c at ~80w), until the cpu shot up to 137w. I had HWINFO sensors running, but I didn't check it cause as soon as I saw the temperature and the watts up in heaven I stopped Prime95, so I can't tell the voltage it reached. However I had MSI Afterburned up, and it's where I saw what had happened (I was checking the PC and the fans and only noticed what was going on when I looked at the screen). Here's the "relevant" graphs from MSI Afterburner: So, can someone explain what happened? What BIOS settings should I change to keep this from happening again, but stay with a good clock speeds. I'll provide more info if needed.

Purchased a 4080, hooked it up, reinstalled drivers. However, when playing games (or doing anything, really) it refuses to go aboce 25 Watts and around 600mhz clock. Really strange issue considering it gives an output just fine. Would appreciate any advice.

I've got a new laptop a month ago and decided to try some gaming on it and it actually surprised me how well it runs newer games (since it has 4GB of VRAM). But I noticed some weird behavior, that happens in some games. For example in Call of Duty: Warzone 2.0 after a while of gaming the FPS starts to drop. After a week of testing I discovered the issue might be in power consumption, as it is always lower than usual when FPS drops happen. What is weird, this doesn't happen in games like Mafia: DE (1080p, High, 60-70FPS) or AC Syndicate (1620p, High, 45FPS). The CPU and GPU are around 86°C and power consumption stays constant around 55-60W for hours. But in games like CoD: Warzone 2.0 (1080p, High, 60-70FPS) and BFV (1080p, Ultra, 60FPS) it suddenly drops to 30W or lower, resulting games drop to 30-20FPS. I thought it's because of power throttling, so I used MSI afterburner, and after some tweaking GPU temp stayed at 65-75°C. Nevertheless the issue persisted, which means the GPU did not throttle. What is also weird, if I restart the laptop and play the games right afterwards, I can play both games flawlessly for few hours. Then the power consumption suddenly drops, even though the temps are still around 70°C. I tried everything I could think of. Everywhere I could I set things to performance mode, V-sync is turned off, drivers and bios is updated to the newest version. The laptop DOES NOT throttle. GPU MUX switched to nVidia only. What could be the issue? It's like the laptop has a problem to prioritize GPU power for the game and doesn't know it has to run at max performance, treats it like google chrome or something. I have ASUS creator hub, where you can set certain app for max priority usage, so that all laptop power is used and focused for that app. But that didn't help as well... (even though the vram is no longer full from background apps). -
Wattage Spikes when start running graphics-intensive tasks
Kilian3D posted a topic in Power Supplies
Hey, I have a 500W psu by enermax (maxpro EMP500AGT with 80 plus). I recently bought the rtx 3060ti oc edition from Gigabyte to get more performance primarily in Blender and Unreal Engine. I have been thinking a lot about buying a new 650W power supply. But since I have read a lot that my 500W power supply is completely sufficient, I have not upgraded for now. To test the PSUs wattage usage I plugged in a wattage meter and run a few benchmarks. I also was playing GTA and redered some scenes in Blender. But I always noticed something. When I started a benchmark, game or render, there was a really high wattage peak of 600 - 780W for a really short time (around 0.5 seconds). I know that my psu isnt 100% efficient but even 510W - 663W (85%) is quite a lot. After this peak my system is running at mostly 350W and max 450W with GPU at 100%. In idle its running with around 100W. Is this normal or should I buy a new psu? -
I have a semi-modular PSU and it only has two daisy chained 8-pin connectors, so that's only 150W. Add the 75W from the PCI-E slot for a total of 225W. The GPU I'm getting soon needs 220W according to its specs. Is a 5W headroom too small?

Im 13 years old and im building my first pc soon. I want to upgrade this pc to a 3700x / 3070 in the near future, and i was wondering if a 750w 80+ Gold psu would be sufficient, or should i go 850w?

Every time I've updated my GPU's drivers Ive seen changes in how it behaves. Originally I was getting high utilization for stuff that didn't require high utilization, so I reinstalled the driver, everything normalized, I was getting lower utilization, of like 50-70% in a game [FPS capped to 60] and clock speeds of 1935 Mhz /1960 Mhz on my 1660 TI with the prefer max performance setting, which would use 100 / 120 watts and this is how it was continuously for several driver updates. I had updated my gpu again after using DDU and now I'm getting really low utilization, around 7%, my clock speed is only 1500 MHz (for the same game) and the power being used is only 41 watts. I thought that was odd so I tried reinstalling it once more, and it's the same thing, Is there something wrong with my GPU? It's not going into that 1935 Mhz anymore on the prefer maximum performance. In DDU I notice that it first detects my 1660 ti and then my integrated Intel HD, Should I have uninstalled that driver? I noticed this time when I tried to reinstall the driver, it auto installed as a 1660 ti after DDU. Specs CPU i7 8700 GPU : Windforce 1660 ti Asus prime h310 plus motherboard 16 gb ddr4 ram PSU 500w Storage : 3 SSD's of various sizes.

I recently upgraded to the i9-12900k and I am having nothing but issues keeping my temps under 90c when under heavy load, at idle I see normal temps around 30c. I changed the cooling hardware setting in bios to a box cooler even though I am running a 360 AIO so that way it would limit my wattage. I saw in a forum that you could set a wattage power limit and it could remedy the temp issues with about a 5% performance loss, but I am unable to find the option to set a wattage limit within my bios. I was never really one to overclock and mess with voltage or anything, but now I need to underclock and I am kind of lost. Any help is appreciated! TYIA.

Hey everyone, the last few weeks I’ve had some frame drop issues on my pc. I’m not going to get into it, but I’m not sure if the following wattage for my ryzen 5 3600 are too low. When I’m playing for example, Fortnite. My CPU is only consuming about 28W of power, is that normal? Thanks -
Hypothetical, my barebones build should consume 495watts: Is 500Watts enough? Is 650Watts "future proof"? And, if I plugged in a 1500Watt power supply it wouldn't explode or anything right? Whenever I've heard people talk about excessive PSUs they cite cost as the limiting factor but I've never heard anyone say anything bad would happen, I think it's better to ask & know if that's really the case just in case.

I have a Dell G7 7588 that I bought in 2018. The specs are i7 8750H, GTX 1050ti, 8GB of RAM, 128GB SSD, and 1TB HDD. I have heard that my laptop is using hybrid power (it's using the AC adapter and the battery simultaneously) because the AC adapter that I got in the box (130W) is not enough to power all the components in it (when I'm doing heavy task like playing video games). Because of that, after 3 years of using this laptop, my battery is currently in a really bad condition. My laptop can only turn on in 15 minutes before it ran out of battery. And also when I'm playing video games (like Apex Legends), my laptop will run out of battery even if it's plugged in, so the laptop will go to sleep mode in the middle of the game. So my question is: how much power does it actually need to power my laptop? Because I was wondering to buy an AC adapter that has higher power output. Does 150W enough? or should I get the 180W?

Hey everyone, I’m not going too in depth with the issues I’m experiencing. But I have a ryzen 5 3600 and I’m experiencing a lot of studdering in some games and I looked and saw my cpu was only pulling like 25W in a game like Fortnite, a few people said that’s a bit low and I wanted to know how I can fix that. I tried to set up a power plan and that helped a bit but I’m still having some studdering. One thing I saw was in the advanced power settings was to put the minimum cpu usage to 85% and the max at 99%, is there something different it should try? Thanks
