Just say single cable..that is not a "rail". Here's some light reading for you: http://en.wikipedia.org/wiki/Power_supply_rail

Anyway, the PSU should be fine for that CPU, and card. nVidia says the 470 takes ~212W if I remember correctly. Your CPU probably ~125W.

I guess the only thing I would check is to see how many amps are on your 12v rail, and see what the 470 takes.

My 550W PSU has 2 12V rails, each delivering up to 25A, and it does fine with a gtx470, and a i5 760 overclocked.

Or just try it

Yeah you will be fine I ran my 470 off a 500w Cheapy for a bit. If you are worried abou t2x6 pin coming from the same wire which I wouldn't, just buy a 2x4pin molex to 1x6 pin.

Yeah, it should work, depending on the rest of your system. Looks like that PSU has 3 12v rails with 18A each. I think the gtx 470 only needs 36...in which case you'd be fine, and still have enough juice for a cpu.

Overclocking..no way.

^yes it has exactly the same amps

Oh, yeah, you can probably get away with OC the cpu. I was referring to the GPU.

I don't know an exact percentage, but I had a e7400, running at stock 2.8ghz, and it did OK with the gtx 470. I should be getting a 2nd gtx470 tomorrow, maybe I can slap together a lga775 build, and run some benches between the e7400 and my i5 760.

If i remember correctly, the only games i had problems with were generally just cpu intensive games that like quad cores, BC2, FFXIV.

How many rails does that psu have? Most new GPUs come with a molex to 6-pin adapter.
