Exactly. IIRC, the specs say that it has a constant 85%+ efficiency. Those 500-800W supplies vary within the 70 to 80% range. But, like just about everyone else here has said, even the most loaded system wont use even half of its 100% capacity, so it's really a pointless buy. I mean, We could be speaking like, 8x Intel Cores + Board + 4x Crossfire HD2900XT(X) + 20-30 HDDs + Watercooling + TEC and/or phase for all of that... I'm not sure how much all of that would use but I know this PSU would cover it .

The only scary part to this PSU is the special power socket. The pins and socket itself are noticeable larger than the average socket, and 2000W would mean you need a 25-30A breaker for the machine itself, provided it uses up past 1600+ W.

Slade, I realize what you're trying to do here, but I think that that just may pull over that... What kind of TEC are you considering? certainly not a 300W model...

But yes, there is no sense in a 1600+ watt PSU.

Also people let's be reminded that a PSU will operate at peak efficiency when about half loaded, so if you're only quarter loading a PSU you are in fact wasting energy in addition to all the cash you blew.

Just because a PSU says it can supply 800W does not mean it will always supply 800W. A PSU will only supply as much power as is required by the components. No energy is being wasted so I am not quite sure what you are going on about.

Not necessarily. Not all PSUs are at peak efficiency there, and many are relatively stable once you reach a certain load value.

Stargate is right. I can have a 78KW PSU, and my system will still only use the amount of power needed to run it. It may be a waste of money to purchase a PSU that powerful, but you aren't "wasting" any excess power with it.

I'm plenty future-proof. Of course, 10 years from now i'll probably have to buy a new psu, just because it will go out. But the new parts are always using less and less power.

What about computer parts using less power in the future?
post #19 of 56
If this PSU had two motherboard connectors then I could see using it as a single PSU to power two PCs, but otherwise I don't see the purpose. I can see 1200W being a good buy with an extremely powerful TEC (which would be undervolted, mind you) and power-hungry water-cooling system, but otherwise...

Precisely, and what percentage of folks that snap up these things like they're made of win are running such gear? My guess, 1%, because most users of TECs will just use a dual PSUs.

Anyone on OCN running such equipment from a 1kW+ PSU? Now, how many of you have 1kW PSUs?
