If you feel the need to have a nuclear reactor in your gaming case, the 2000W ATX Power Supply from Ultra Products should be enough for you. Being unveiled at CES, the 2000W PS is modular, and feeds up to 1800W on the 12V connection alone.


With all that power, you're going to be able to support quad core, quad GPU cards, or a gigantic RAID system to store all your homemade movies. No word on price, but we're guessing somewhere around the PlayStation 3's price tag.

The "20 A" circuit I was talking about was for the in-home wiring. If your computer is going to draw 2000 W, that power has to come from the wall socket the computer is plugged into. In the US, your home runs at about 110V (sometimes you'll see 115 or 120V...I think that's just geographic variation). Voltage(V) times current(A) gives you power(W)...so if you want 2000W to come from your 110V socket, you need 18Amps — basically, a nearly saturated 20A fused circuit.

Based on what Matt-B was saying, I could be slightly wrong...but I think according to this article, most homes use mostly NEMA 5-15 plugs, meaning that no matter what the fuse is set to (the fuse supports multiple plugs), the wiring going to the plug is designed for 15A at 125V maximum. The apartment where I live has a pair of 50 amp fuses that run the whole place...but the plugs are all NEMA 5-20's, supporting only 20A each maximum.

So, I guess the point is that if you want to run this power supply, you must have NEMA 5-20 plugs, and the fuse behind that plug must be at least 20A...and you better be careful what else you plug into the same fuse/circuit.
