A 400W good psu is plenty. More than enough!

The RM850x is fully modular, meaning that even the always-necessary 24-pin ATX cable is removable. The SATA and Molex cables are flat, ribbon-like, but the larger PCIe and ATX/EPS power cables are normal round cables with black nylon sleeving. The designer could not use ribbon-like wires for everything because small filtering capacitors are hidden inside the sleeving of the larger cables. The cables are supplied inside a nylon storage pouch. No cable straps are supplied here either, Corsair is using simple wire ties. It might be an affordable version of the RMx line, but the RM850 has two EPS and six PCIe connectors so it will easily support a potent gaming system. Only the PCIe cables use thicker 16AWG gauges, up to the first connector, for lower voltage drops under high loads. There are no in-cable caps for better ripple suppression, while the distance between the peripheral connectors is too small at 100mm. Ideally, it should be 150mm. The RM850x 24 pin cable is very hard to bend? Is RM850x 24 pin cable possible to destroy motherboard connector? The RM850 In-Line Cable Connectors are worst according to their quality? Which are the other differences about cables?

There is a new (now pretty widespread as can be seen in the forums of nvidia: https://forums.geforce.com/default/board/227/) where rtx 2080 ti cards are getting bad (artifacts, blue screens) after a few days of use. People are sent new cards that have the same defect. Can we have at least a news on this? Maybe nvidia will make a statement if it gets more coverage?

A power supply rated at 1000w means it can deliver if needed up to 1000w, but less if the load demands less. If had say 12V 1000w supply then the current capability, max of what can be drawn, is 1000/12=83Amps, but it will be putting out this power and amps only if the load is such to demand it. In this case a load of 12V/83A=0.14 Ohms. If the load is higher resistance then less current will be needed and the supply will be supplying less power. The 1000w or whatever the rating means the max wattage the supply can deliver.

In the words of the great philosopher band Midnight Oil and WoW military leader "Dives" a fact's a fact, handle it! If your CPU is not ranked how you like on the gaming charts below, deal with it! Tossing a hissy fit on the internet (however comical) does not make it any faster. If you fail to understand the charts and why it's important to test at 720p and 1080p, that is a you problem and your lack of understanding. Get educated then come back and make a post rather then embarrassing yourself.

I am building my new system and i have planned on buying a 1000w power supply for it. My question is: "Is a 1000W power supply really necessary or am I just wasting my money?" Is there any use for having a 1000w power supply? What could it do that a normal 600w or 750w power supply can't do? I was buying a 1000w power supply because I want my new PC to last for awhile and not have any problems. There is really no specific reason i am getting one other than to have a more powerful computer. So i am buying top end products. But i am thinking spending $200 on a 1000w power supply might be over kill. What do you think?

Hello Everyone! I am on the market for a new CPU/Mobo combo and I don't really know what to get. I currently am running an I7 6700K with an Asus Z170-AR mobo. I am interested in what AMD has released recently but I have been out of the building PC game a while now. Every benchmark I look at has the I9 9900K beating the Ryzen 9 3900X in gaming benchmarks. I play everything from large open world games to tight quarters shooters. Think Skyrim to Modern Warfare. I play everything and like to max out my graphics and get the most FPS possible. I usually have Discord and Chrome running while I play games but it's nothing really intensive. Maybe Google Play Music or YouTube running. I haven't really streamed while gaming at all. A few times but not enough to sway me from one CPU to another. I guess my long winded question is, for future proofing, should I wait to see what AMD has in the pipeline with Ryzen 400 in September or because there are some decent deals right now just get one of the following setups? I chose those motherboards due to being told they have awesome VRM and memory controllers. Ryzen 9 3900X - Gigabyte X570 AORUS ELITE I9 9900K - Gigabyte Z390 AORUS ELITE Thank you so much for your help! Hope you're all staying safe and healthy during these times! EDIT: I should probably add that I am running a NVIDIA RTX 2080 Founder's Edition.

Very helpfull list. Thanks! The point of the one province in China, is that many of the power supplies made there are often made in the same plant. they are nearly all the same... but when one puts more wattage without changing the engineering, to meet a marketing brochure, then you have probably gained nothing. The part the differentiates the power supplies is the UL code on the label Some brand names and models have identical UL code is the same, meaning it has been tested by United Laboratories, and accepted for US distribution. As to backing it up, a Gurgle search will provde you with plenty. There have been some super articles by PCPower and Cooling in CPU magazine, among others. In general, wattage is not very important once it is above 550 watts, as long as the distribution along the 12V rail(s) is correct. Amperage that is steady is critical. A great cooling fan. Quality transisters, resistors, circuit boards... and the ability to maintain steady output underload. Except for a few of the PC Power and Cooling power supplies, you don't know what you have, if anything, with a high wattage unit. Do a Gurgle search for power supply reviews... for those that are tested under load, and tested for heat and circuit fidelity. As mentioned above, if it has reserve power after supplying the needs of the video graphics card, the engineering is probably good regardless of the wattage on the label. The power supply postings on this forum that list acceptable models is pretty good, although they downrate some pretty good power supplies that I have never seen fail. Properly referenced, the power supply in most of the computers you will work on are referenced as "Constand voltage switching power supply," and this is supposed to mean that the power supply puts out the same voltate to all the interal components, no matter the voltage of the AC current that runs it, or the capacity of that power supply. Switching power supply refers to the techniques used in regulation to assure that the power supply perform these tasks in a small, standard sized unit, at a low price. But it has become a place to make a lot of profit. It wasn't that long ago that a good power supply cost $35 and a great one cost $65. Most of the rest is money in the bank, not performance for the computer. Only the improved designs of video graphics components changed that mix. Most failures were to lousy components in the power supply. Some were sold in volume for $5.00 each to the likes of such manufacturers as Compaq and the rest. There are basically needs for +3.3 Volts, +5 volts, and +12 volt rails, which were techically set aside to be independent within the power supply. But the cheapos started finding ways to share circuitry, making them less independent than they should be, and thus a lot less reliable. Finally, the power supply must ensure that the system doesn't run unless and until the voltages supplied are able to operate the system properly. The power supply should actually prevent startup if there is not sufficient power detected by the motherboard. This Power Good signal must always be present in order for the motherboard to run. When the power supply is well built with quality components that do not burn out like a light bulb, then good power results. When the power dips or rises, the signal that there is good power is gone, and the computer resets. In gamer systems, there are many devices that detect that power output is correct. Video cards won't run without it. Memory will not. So that output of the power supply must be adequate for all demands, regardless of what demands are made on it. Poor components and circuits too far out of range foul up this system. Some computers quit. Some burn out key componets before they have time to quit. The better the circutry, the better the power supply meets the demands on all these rails. Some are not engineered well enough to do so. Some do not have electrical components adeequate to the task. Some burn out.
