[XTReview] 2000 watt external psu - Page 3

post #21 of 30
Probably not as cost effective as having 2 PSU's. I find that having 2 750W PSU's rules anything else.

Because they are in competition.

Just because it isn't necessary doesn't mean people won't buy it. So just because you will never use 2000W it means all PSU makers should just shut off all R&D and just produce current designs?

I know were you are coming from, but that would be like saying cars can already go 200+ mph there is no point in bringing out any other cars.

Maybe you could use one of these for a folding farm...

Not only that, but if it runs on 120V like here in the US a 2000W PSU will pull nearly 17A of current. Most circut breakers and fuses are rated 15A....occasionally you'll find a 20A installed in new (2000 or newer) construction. Its a fire waiting to happen.

Thats what I have always wondered, when they say 2000 watts, is that the sum of all the voltages created and their respective wattage?

Crude example but lets just say I have the 3.3volt at 100 watts and the 12+ at 200 watts, do they just add those up and say its a 300 watt psu?
US households generally use 15A and 20A breakers. Older homes may use smaller ones. Since the US use 120v standards, that's 1800-2400w lines. However, there are generally more than one outlet on each line. Also, PSUs are only 65-85% efficient. That means this unit will probably need to draw around 2400w to provide 2000w.


As for PSU ratings, I believe the maximum output rating is just that. The maximum output of the PSU. This is not the aggregate of the maximum output of each rail.

BTW.... I believe this isn't a 2000w PSU. I believe it is just two 1000w next to each other.
Once again...

ah, of course.

Ive yet to see a GPU which requires a 2000watt PSU though

SLI might be, or at least Tri-SLI, But Crossfire is way closer to being mainstream now.

That 2000W PSU is to electricity as the HUMMER is to gasoline.

Oh, and some surge protectors can't even handle that much. Hope this thing protects itself, and the computer. I expect it to cook my breakfast as well.

GPU's don't really require that much power people... I don't care if you are running even four GTX's... you don't need more than a 1000W PSU...

EVER!
