need some help

post #1 of 6
Thread Starter 
Alright so I recently bought two gtx 480's to run in sli and was going to get a Ultra X4 1600 psu to run them, I know its overkill but it was cheap and I had the extra cash. But my water heater went out and I had to get a new one and now I'm in need of advice/recommendations for a new power supply. I already have a BFG 800 watt psu from back when I ran three 8800gtx's in sli, but I don't think that will be enough to cover it. So I have around $120 to get a power supply to run the following components. I'm leaving everything stock until I can get a quality psu but right now I just want to be able to run this beast.

Motherboard Asus Maximus Gene IV
CPU 2500k
MEM 8Gigs G.Skill RipJaw X 1600Mhz
HD1 Hitachi Sata3 7200rpm 1.5tb
HD2 Ocz Sata 3 120gig SSD
GPU's 2x EVGA GTX 480's SLI
DVD Asus DVDRW
And 5 case fans

Ok, I looked, and what I would do is for the time being use your 800 watt PSU and save about another $50.00 and you can get a very good PSU that will last and be fine with your 480's

Once you get into the $159,00 to $170.00 range you can really get a much better power supply!

Hey mate, since all I do all day is compute things first of all I'll say this: the BFG 800W PSU should work: GTX 480 TDP ~250W; Core i5 ~100W; motherboard ~20-30W; the rest ~50W; the total is about 700W, probably quite a bit lower in the real world which brings the 800W PSU load at about 85%.
EDIT: No Furmark/OCCT/Linpack/afterburner etc as these push chips beyond their TDP.

For the long tern 85% PSU load is a bit too much and you'd have no OCing margin so maybe a 1KW would be good for the peace of mind. I haven't found on newegg any 1KW+ PSU within 120$. My advice then goes like this: use the BFG for now @ stock clocks; when you'll have some 200$ go for this Corsair 1050W PSU.

Thank you very much for such a fast response! I was so worried that the 800 watt wouldn't work at all, or would fry my components!! so what psu would you recommend in that price range?
