corsair 750tx or 1000tx if you're running a lot of other things off it such as optical drives, hard drives, an overclocked cpu, lots of fans, fan controllers, etc.

850 or a very reliable 750 with lots of amps try to get over 60 amps. here are a few to look at, NCIX.com - Buy Antec Truepower Quattro 850W Power Supply ATX V2.2 EPS12V 20/24PIN Active PFC 80PLUS Dual 8PIN PCI-E - TPQ-850 In Canada.
NCIX.com - Buy Corsair TX750W 750W ATX 12V 60A 24PIN ATX Power Supply Active PFC 120MM Fan - CMPSU-750TX In Canada.
NCIX.com - Buy Coolermaster 850W Real Power Pro ATX12V V2.2 24PIN Ultra Silent 135MM Fan Six 12V Rails SLI Ready - RS-850-EMBA In Canada.
NCIX.com - Buy Silverstone Decathlon DA850 850W 20/24 Pin Power Supply ATX / EPS12V Active PFC 120MM Fan - DA850 In Canada.
NCIX.com - Buy Silverstone Strider ST1000 1000W Modular Power Supply ATX 20/24PIN 135MM Fan High Efficiency Black - SST-ST1000 In Canada. that 1000wstrider is just as much as some 850w psu's has the 8 pin connectors you will need, and is modular. im going for the stf100 personaly(1000w strider)
NCIX.com - Buy Enermax Galaxy Dxx 850W Power Supply ATX V2.0 EPS12V SLI RoHS 24PIN 135MM Fan Modular 4PCI-E - EGX850EWL In Canada.
NCIX.com - Buy PC Power & Cooling 860W ATX 24PIN ATX Eps 64A 12V Power Supply W/ Voltage Adjust - PPCT860 In Canada.

all reliable power suplies.

Default Re: PSU for gtx280 SLI

nice. A little off topic but I read around and I dont have a video card or monitor yet, but I have my fan/temp controler installed....after getting the obvious error from turning on my computer, my temps are around 29*c, is that a good indication of what I will be around at idle? Also, I sorta installed the CPU fan/sink without replacing the thermal compound...so im trying to get everything right this time so I dont end up buying the wrong products (bought a 520hx PSU b4 I knew which card I wanted >.<). Someone plz recommend the best thermal paste. My Rig is almost done, but Im about to get a credit card, and im gunna max that sucker in 1 sitting just so I can get this thing finished.

My rig:
Intel Core 2 Quad Q6700
Seagate Barracuda 7200.11 ST3500320AS 500GB (x2)
EVGA 132-CK-NF78-A1 LGA 775 NVIDIA nForce 780i mobo
CORSAIR CMPSU-520HX 520W ATX12V
ARCTIC COOLING Freezer 7 Pro
Thermaltake Armor
Crucial Ballistix Tracer 4GB (4 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

im getting the gtx280 for the vid card. SLI later.

tx2 will be your best thermal paste, as for the psu i strongly recomend teh strider 1000wyour cpu temps will be a litle high, i would definatly get a tuniq tower or a thermalright 120 ultra with a fan for a heatsink.

Why are you SLI'ing?

If you got 1 gtx280 you would be fine in any game, 100fps+ and you could keep that corsair 520hx, which is a great psu.

1000w psu is a bit much a good 750w would do fine.
