PSU for Dual 6950s? - Page 4

No it does not run at 96% efficiency in any tests (and it's a dated double forward topology, you won't get that high efficiency anyway)... It's a 80 Plus standard unit and at best it hits around 85% efficiency. And I wouldn't say it's "medicore" (that's a little harsh), but it's an old and dated design based on the CWT PUC standard. It has OK voltage regulation, OK ripple supression, and the price is out of whack for what you're actually getting; an average 1000w. There are far better choices than the HX1000.

If you mean 750W units, yes. Really 650W would be fine but 750W is more sensible.

really..i don't need an 850 then!
would putting in a 460gtx for cuda in addition to the 6970s be possible?

As far as I'm concerned, modularity encompasses both full modularity and semi modularity, and if someone wants full modularity, then they should specify that. Also don't forget the Silverstone Strider Plus and Strider Gold units for full modularity.
850w for 3 6970s? as much as id like to be able to drop in a 3rd 6970 on my ax850 im pretty sure it would die from a 3rd lol

How about the Lepa G700-MA? 80 plus gold, fully modular, decent (though not amazing) performance, for $100. It should be great for 2x HD 6970.

The Lepa brand is virtually unknown, but under the hood is an Enermax Modu87+. Solid unit.
