Im in the market for a new PSU for a new system build. I want a PSU that will support nextgen DX10 video cards (i.e., Nvidia 8800GTX or equivalent) in SLI/CrossFire. If possible, for expense reasons, I would like to stay within the 600 750 watt range (is this realistic/doable? I read an article that suggests a 700+ watt PSU isnt necessary for nextgen DX10 video cards in SLI -- anyone have any comments/thoughts on that?)
What I need to know is will any of these PSUs (listed below) fit the bill (even though they don't officially support nextgen Nvidia 8800GTX video cards in SLI)? If so, which do you recommend and why? If not, what other PSUs do you recommend?
Corsair HX620W (620watt) newegg.com, zipzoomfly.com
Silverstone ST75F (750watt) newegg.com, zipzoomfly.com
Silverstone ST75ZF (750watt) newegg.com, zipzoomfly.com
SeaSonic M12 SS-700HM (700watt) newegg.com
Im leading toward the Corsair HX620W because of its price, features, and its quality/performance (it has received very excellent reviews). Plus, I read a article that said While the [Corsair HX620W] PSU does not officially support nVIDIA's GeForce 8800GTX in SLI, since the HX620W only has two PCI Express videocard connectors, I don't think it would have any problem powering that beast should you use a couple of molex to six pin converters (Anyone have any thoughts on this?).
That being said, the others have all gotten good reviews too and they have more watts - I also believe they have four 12V rails (as apposed to three like the Corsair). Are any of the differences between these PSUs significant? Do I need more watts or 12V rails? Additionally, between the two 700 watt Silverstones, is there a significant difference in quality/performance? Is one better than the other? The ST75F is more appealing because it's cheaper and has modular cables (the ST75ZF doesn't), but it doesn't "officially" support SLI (the ST75ZF does).
Also, regarding PSUs with fans on top (and not on the back), will such PSUs (such as the Corsair) work in the case I ordered (ThermalTake VC3000BNS)? The case doesnt have a top vent, does that matter? (Sorry if thats a newb question!)
Thanks in advance for any help/info given!!!
