What PSU for GTX 470 SLI?

[muskie32]

What PSU for GTX 470 SLI? System is going to have 2 GTx 470's a i7 920 and a few hans and hdd's. I am thinking 750w. But what is the minimum? system is going to be at full load 24/7 folding.

750W PSU is good for a GTX470 SLi but I'm thinking a 800W PSU would be better. An extra 50W wouldn't hurt the pocket that much.

And I am hoping to get one for under $100

The value of a good PSU especially if you want to have it running 24/7 folding is crucial. You can have the best hardware but all can be crippled by a lousy PSU. Those that you recommend of I have not heard of them so I can't really say they are good as I usually stick to what works like Seasonic, Antec, FSP, Corsair and Silverstone.

ADD : This is a good choice as well. It is cheap and 750W of true power.

Now you're talking. That PSU will last you a long while thru many upgrades. Good choice, but a bit overpowered for your immediate needs.

Of all the ones you linked to, only the Corsair unit is worth a crap...the PCP&C unit isn't bad, but it's not nearly as good as the Corsair unit:

"The Bottom Line

When the PC Power & Cooling Turbo-Cool 1KW-SR was launched it may indeed have been the “biggest, baddest power supply – period,” but while the king was looking down the jester stole his thorny crown. This isn't to say the unit performs badly as the Turbo-Cool does perform well, but what it does mean is that the 1KW-SR fails to meet the expectations instilled by PC Power & Cooling’s marketing, its own labeling, and the performance of other units currently on the market.

These relative failures make it tough for HardOCP to respect or even believe PC Power & Cooling’s marketing claims. A portion of this letdown is mitigated if a user buys direct from PC Power & Cooling. While you still get the same product you will experience the best selling point of a PC Power & Cooling PSU; their outstanding North American based customer service including being able to have your power supply custom tailored to your exact cabling needs.

Simply put, there are much less expensive power supplies at and above the 1Kilowatt rating that show to be quality units. Save yourself an easy $150 and spend your hard earned money on a PSU other than the PC Power & Cooling Turbo-Cool 1KW-SR as it does not live up to its self-proclaimed marketing hype and is overpriced in today’s PSU market."
