Is this an overall good PSU. Maybe I have probably asked this with this one? It might be running with two eVGA 7900GTO someday, Intel Core2Duo.....well look at my specs in my sig. Hiper HPU
Yeah it's got SLI support...pretty good, should work fine, but if you're spending that much money on a PSU, why not go for a more well known and reliable brand, such as Antec...
The Hiper is 4A short of the +12V@34A recommendation for SLI'd 7900GTOs. I wouldn't recommend it. Frankly, I don't consider ANY $100 PSU with only +12V@30A over dual +12V rails to be good value. Heck, the $70 Enhance units thoroughly trump this PSU in pretty much every way, whether you judge by efficiency, build quality, voltage stability, or total +12V output. The Hipers look good, but i've never considered them great value.
As for my own recommendations, the aforementioned Corsair would be top of my list for a good looking, modular PSU. The OCZ GameXStream 600W is another strong unit. ZipZoomFly have the Corsair at $119 with free shipping.
Take a look at PSU101, and try to only post one thread on the question.
