Agreed. My system pulls around 505w with everything being stressed at the same time. And this is with my dual core too. A 650w will do nicely. I'd snag one of the Corsair HX750 PSUs just because you might want to upgrade again. No sense skimping on the PSU for any reason. ^^

He plans to run CPU and GPU at stock.

You are running in a OC and pulls 505w, so how much he will pull?
There is no reason to upgrade just for the sake of upgrading because its fun if he doesn't want to.

My current HTPC was with a 5 years old HX520, running a 920 @ 3.8ghz and a stock 470 for the a couple of months at full load folding (on both CPU and GPU). I now "upgraded" it with a newer HX650 and added a GTS250. Still folding fine.

So I don't think a lower specs rig should have an issue with a 550w PSU unless the PSU starts to "fake it" and brings a lot less amps and watt than it should.

A Quality 550W continuous power supply will power any single GPU and any single CPU even overclocked.

I had a GTX480 overclocked, a i7 860 overclocked and all the normal PC accessories attached to a 550W power supplyand ran it fine for a few months even when stress testing. (It was an OCZ power supply).

It should work at stock. If you plan to overclock the 470, you should get a better power supply. The BFG GS-550W can only output 432W on the +12v rails. If you had a higher quality 550W PSU, you could have overclocked on it.

419W with a 3.65GHz i7 965 and a GTX470 which is from the wall, so at most it will draw 380W from the PSU. This is with their water cooling setup.

a good 550w psu can handle it on stock..going overboard by just a BIT well......you can find out for yourself what happens next..but for sure you can run it fine..

Check Out The PSU Calculator Here

It reads you need about 448W total system power if we are talking about your sig rig, your bro's seems to actually use less power...

Put his specs in the PSU calculator..

I say yeah, not problem the 550W will handle it. However I would recommend saving for a new better quality. Antec NEW TP650 would be better suited. High quality PSU's are pretty much a must for gaming builds as we tend to put some serious stress on it..

BFG isnt bad if he already has it, but dont buy one. BFG is out of business...

it's fine, i run my 470 overclocked but no volt increase up to 740 on core from 600.

and yes i overclocked my x6, but overall my PSU can keep up with it.
