Thank you for taking the time to read my question. Before I begin, I just want to say I'm a bit new to building PCs, and I'm actually in the process of building my first Gaming PC, and I'm in a state of paranoia about my hardware choice, and I was wondering if anyone can give me advice or inform me if this hardware I chose is good enough.
Power Supply Unit: Corsair Professional Series HX750W 750W PSU
Basically, I want to know if this PSU is enough to support my video card. I've been told the GTX 580 is quite the power hog, and I've had bad experiences with PC's burning out due to the lack of a decent PSU. I asked one of my friends if this supply was good enough, and he did not ease my thoughts at all because he said that 750w was not enough and that I can seriously damage my Graphics Card and other components.
In short, all I want to know is if I can safely run this GTX 580 SLI safely and without worry with this PSU. I'm a bit paranoid about this and would appreciate any help.
If your actually going to be running two 580's in SLI then you definitely want a bigger PSU. For a single 580 card then the 750 is fine. Go up to an 850 if you plan on a high overclock system with a single 580.
I really appreciate your prompt answer and linking me that useful chart. But since I'm OCD'ing over this, just to be sure, will this limited PS damage my PC at all? I must admit I'm spending quite a lot of money on this rig and I want it to last for at least 4-5 years. I don't plan on overclocking the computer at all, but my friend tells me that with only 750w on such a powerful graphics card I could be risking hardware failure or generally frying the card.
