Hi I've been having this issue for a while now and I can't properly know what to replace since I'm not sure which but it all seems to point to either PSU or GPU. The past couple of weeks I also can't borrow a friend's parts since I've been stuck in the house due to work-related issues where I'm currently doing remote work. My system specs are: CPU: i7-8700k Motherboard: Maximus X Hero RAM: Vengeance Pro 2x8GB GPU: EVGA 3080 FTW3 Ultra Storage: SN730 1TB / 970 EVO Plus 1TB / Samsung 860 Evo 500GB / WD Blue 1TB/WD Black 4TB PSU: Corsair RM850x(2015) OS: Windows 10 64-Bit So my first issue was that whenever I'm doing something intensive with the GPU(from what I've observed) it auto reboots my system without any BSOD, like it just goes black and starts on again. What I did was to reconnect everything and also the connections to the PSU itself. It worked for a while and was even able to stress test with 3DMark and OCC. However a week later I began to BSOD reboot. It took a couple of retries of testing to actually see the BSOD error since I was rebooting so fast the BSOD only appears for a split second. From what I can remember seeing it showed WHEA_UNCORRECTABLE ERROR which means a hardware issue from what I've gathered. I tried reconnecting everything like before, setting BIOS defaults, using 1 RAM module at a time and nothing seems to work. Minidumps doesn't seem to appear anymore either, last minidump I got was from March. I also think I managed to click a drive due to how many sudden reboots it had. I did test my RAM using memtest86 and OCC, they ran fine even after a few hours. I OCC tested my CPU and was also fine. Should I also do Prime95? Temps are also pretty fine from monitoring, nothing running hot. What I did found consistent is that whenever I do 3D load OCC test on the GPU on stock settings, it reboots instantly. So does PSU test which basically also just uses the GPU. If I do VRAM test or underclock to around 1500mhz it runs fine for a good few mins, and it'll BSOD reboot again only when I multitask for a while. This doesn't happen consistently, rather it happens on random. I think the underclock that was the most stable was around 1100mhz~1200mhz. I checked the power and it was showing the GPU was drawing around under 200w during OCC test if it was below 1200mhz. At 1300mhz above it runs above 200w. At stock settings it's around 375w IIRC, and my usual undervolt at .7v is around 275w. This leads me to assume something's wrong with the how the GPU draws power. Is this possible from the transient spikes 3080s/3090s are known for? I've been using this PSU for a few good years now and only has happened after 6 months I got the 3080, which was fine for a while as well. I can still have the PSU RMA'd probably, I just need to think of a good excuse. I wonder what they'd actually consider for an RMA? I'll try to borrow a friend's parts once I can. The PSU however is going to be the tricky part since my friend has only 750w, and from what I've it can handle the 3080 but due to spikes an 850w+ is recommended.

I was GPU-less since September last year, as I sold my 1080 Ti Strix after Ampere was announced. Didn't expect stock would kill itself, so I didn't get a 3080 until mid-December, and glad I got the one without the red lip. Didn't install it to my PC until just now since I wanted to get all the parts I have before I started switching cases so I would cable manage everything in one go. So, literally just hours ago, I finally finished switching cases from the Phanteks P350X to the O11DW. My main gripe about the O11DW, that while it is quite roomy, it has bare bones routing or tie points for cable management, the middle and upper top are what you get. It took me hours, first by remaking my cables, and actually managing the cables inside the case, whereas my P350X my only issue was that it was tight but I managed it. Second issue was the HDD/SSD mounting at the back plate, it was flat enough that it was difficult to insert SATA power connectors to the drives. I had to route the connector under the drive, luckily SATA cables are flat. Third, is a small thing but it can be attributed to the Motherboard/fans, but USB 3.1 connectors is impossible to connect to the header if it's at the bottom and if you have fans there. Asus moved the USB header to the side near the 24-pin on Maximus XII series it seems. I actually liked how it turned out. I think there's a certain aesthetic to fans having no LEDs and how white accentuates the color of other sources of LEDs. After I bought the O11DW, originally I was gonna buy RGB fans like the UniFans, but I got the idea for this theme after I saw some O11DW builds on PCP using only Arctic P12 white fans and some LEDs. The Phantek's LED strip is probably the thinnest LED strip that's diffused that I know of, if anyone can suggest another I can check it out so I can make the LED strips more subtle. The 3080 + cables are a tight fit btw, almost hitting the glass. Since they're PET cables as well, it's stiff, so I had to really flex it back. Still somewhat WIP. I plan on either buying additional 16GB ram for production work as 16GB alone isn't cutting it anymore for me, or getting a Dominator Platinum RGB White 4x8GB. Might still try to make the LEDs' cables hidden. Also gonna do some cable management on my desk, buy some desk wire clamps for my cables and an aluminum bracket for my surge protector under my desk. Might also make/have someone make a custom GPU bracket for me, as the FTW3 is a lot heavier than my 1080 Ti Strix. Still rocking the 8700k, originally I was going to switch to the 3900 earlier last year, but I was spending so much on my audio hobby left and right, that I already spent more than my entire PC is now. Although I might switch to AM4 this year, preferably 5700 if that comes out, or go broke 5900. Alternatively not at all, since there's a chance I'll be living in Japan this year or the next, so might build a new PC altogether, just going to bring my drives and GPU with me.

Yea, I'm leaning towards the 1TB because it's just cheaper overall. Do you have any source? Because I'd believe you, but I'm quite skeptical.

I know I would barely notice any performance in read/write/loading difference amongst the three. However, how about in other aspects? Specifically longevity, and how slow they are in comparison to one another the more they get full? Looking to transfer my OS to here from my 860 Evo. Planning to get the 500gb version, with all three are priced similar to one another, with the SN750 $7 more and the CS2130 $5 less. Their 1TB version, the SX8200 Pro is the cheapest, with the SN750 being around $40 more, the CS2130 $10 more. No 1tb for the CS3030 atm. Tempted to get the SX8200 Pro 1TB tbh. 970 Evo is also around the same price, but it's not the Evo Plus, which afaik is the better and pricier one and the Evo is actually slower than the other three.

Unsure if they even sell those separately. Also, in that regard of airflow, from what Science Studio showed us the temp delta of the P400A white isn't really that much of an improvement either. It was seen equal to stock NZXT H500 on a negative pressure setup. Adding an exhaust improved deltas, but tbh that can be said to almost every case even the ones with good airflow already. The 220T that has the same 3-front fan config on stock and Meshify S2 on stock handily beats the P400A by a couple of degrees. The P400A black might have better airflow due to less coatings of paint. For comparison, these are the holes of the P400A white vs the H500 Mesh from CM.

Hi, I went ahead with the Corsair RM850x Gold. Frankly I know this is more than enough what my entire system would use, but I was passing by a shop that had it on sale that's on par with the price of the Seasonic 750w Focus Plus Gold, so I just went ahead and took it.

Alright, I'll check it out. Well I did read this. And read that Although I don't know if that includes multiple other accessories or just an OC'd CPU and GPU. I also know about realhardwaretechx's page, but again, I don't know if a "whole system" in context means the PC itself. So I was wondering if I needed a bit more headroom. Also, I wanna know which of the three brands I should go for. I read that the Corsair one is better, but I don't know if the price is justified. While I did read that the Seasonic one does have some noise?

I'm thinking that a 650w should be more than enough, but I'm still unsure. Currently looking at Seasonic Focus Plus, Corsair RMx, and EVGA G1+ since these are within my price range and the only ones that are currently available to where I am right now. The Corsair is the more expensive one of the three, usually $25ish~ more from 650w to 750w. I think I read somewhere the Seasonic one gets a bit loud. What I have are CPU: i7-8700k Cooler: Deepcool Captain 240EX White RGB Memory: x2 8GB DDR4 Corsair Vengeance Pro RGB White Motherboard: Z370 Asus Maximus X Hero (Wifi) Graphic card: Asus strix GTX 1080 Ti 11GB OC Case: Phanteks Enthoo Pro M SE Storage : 500GB Samsung 860 Evo 1TB Samsung 970 Evo Nvme 500GB 5400RPM Seagate 1TB 5400RPM Western Digital Blue 1TB 7200RPM Western Digital Blue (2 are inside an enclosure) Power supply: Unsure Peripherals: Logitech G502 Spectrum Corsair K95 Platinum RGB Audio Technica AT2020 Condenser Mic Sennheiser HD600 Open Headphones YAMAHA YAS-108 Soundbar Displays: Asus VZ249 with an HDMI Switch attached(I also use this for my consoles) Acer Predator XB271HU Others: x3 NZXT Aer Fans 120mm MediaSonic ProBox HDD Enclosure I'll be OC'ing both my GPU and CPU. I also do some light streaming, video and photo editing with such like Vegas Pro/Illustrator/Photoshop, use 3D CAD software like Catia V5, and some other more similar applications. TIA
