ePOWER EP-2000P10-T3 2000 W ATX12V Ver.2.2 SLI Ready CrossFire Ready Modular Active PFC Power Supply - OEM

Pros: AMAZING, Currently running my computer, refrigerator, microwave, and all the lights in my house.

Cons: After a few months of neighborhood power black outs and outrageous electric bills, i wired the extension cord to the next block and there was no more problems.

Overall Review: I think the block next to us is getting mad.
Pro tip: Hook directly to nuclear reactor for most efficient use.

Pros: If you want to run 30 hard drives and/or no more than 2 high end video cards this would work fine. You can make 3 video cards work if you are not running the high end cards or if you are only gaming at less than 90% load. See cons on how.

Bottom line, you don't need a 2000W power supply for 3way SLI anyway. use a smaller PSU that is designed for 3-way SLI/Crossfire. (maybe a 1500).

Cons: If you want to run 3 or more high end video cards at full power for things like bitcoin mining, this power supply WILL NOT WORK due to very poor rail design.

High end cards pull over 350W at full load and each rail only supports 240 or 264 watts and only 5 rails are available for PCIE/HDs. The other 2 rails are for the MB. There are only 5 PCIE cables that are split across the 5 rails. These PCIE cables are split across the rails due to the low wattage supported on each rail.

You can get one more PCIE connector by taking both molex cables and splitting the PCIE across two rails with a molex to 8 pin cable. Do not connect both molex connectors to the same modular cable or YOU WILL BLOW a 12v rail at anything over 50% load on the video card. Mathematically this will work for 90% loads,since you are putting 1.5 cards across 2 rails (~350+175=525W on two 240W rails=480W). BTW, they don't tell you which rails are 240W and which are 26W. However it is really up to how the card splits the load across the 12v inputs on each cable. If it is not well balanced, then this strategy could fail much sooner than 90%. I WILL NOT WORK FOR 3 way BITCOIN which will load it to 100% unless you throttle the hash rate way down, which defeats the purpose of buying the high end card in the first place.

Bottom line, you don't need a 2000W power supply for 3way SLI anyway. use a smaller PSU that is designed for 3-way SLI/Crossfire. (maybe a 1500). Or use 2 power supplies.

Overall Review: I was looking at this PSU for doing a 4-way bitcoin mining rig. While it has enough total power. It is totally unusable for this application.
