Would my PSU handle 3 x GTX480

post #1 of 8
Thread Starter 
Hi guys I would like to know if my current PSU can handle 3 x GTX 480
Here's what I'm running at the moment

i920 overclock @ 4.2 watercool
12 gigs of Sektor 7 DDR3 (6 x 2)
2 x 1TB sata
2 x 1.5TB
2 x 40 intel SSD drives in Raid 0
1 x 24x burner
eVGA X58 3X SLI mobo
Kingwin Mach 1 1000-Power PSU ABT-1000MA1S
2 x GTX480 1.5 (1 is an eVGA GTX480 Superclocked the other is a PNY GTX480 brand)
ASUS Xonar HDAV1.3 Deluxe 7.1 sound card

For watercooling I have a
Swiftech MCP655 with an EK Waterblocks EK-D5 X-TOP Rev 2
XSPC Rasa CPU (Acetal) Chrome waterblock
3 x 120mm single radiators
XSPC RX120 (the fat one)
XSPC RS120
Black Ice SR1 120
Water Tank Z-Multi 400 Reservoir
Danger Den single 5 1/4" Bay Reservoir (left over from a previous second loop, i decided to leave both on )

Have a third GTX480 sitting in the closet with a waterblock, my plan was to watercool the cpu and 1 GTX480 and run the other two on air but my concern is the PSU.
Would it be able to handle the load with 3 GTX480 at stock speeds? I don't plan to overclock the video cards at all nor do I care about torturing them with benchmarks. I mostly do mild gaming (3-5 hours a week at most bad company 2, l4d etc) CPU is overclock as you can see.
So would the current PSU be able to handle it or should I just pick up a 1200 PSU and call it a day. I rather not buy a new PSU if it's not necessary but at the same I don't want to turn my pc into a forth of July fireworks display
thanks

Not sure, I've never heard of that PSU brand, does anyone know if they're any good? If it's a decent brand then yes. But I'm not sure your cooling setup will be sufficient.

Personally I don't think you'd get away with it. I think you'd be safer with a 1200W, but I might be mistaken.

Agreed. The 480s chew through power like a hippie chews through bags of munchies. A kilowatt might do it, but I wouldn't risk it. Go 1200.

Kingwin is a pretty decent brand, but the wattage itself makes me doubtful. I'd go with a 1200w PSU
