Yes I wouldn't recommend a 550w Kingwin for GTX480 sli at all for anyone and you are probably right on the fact it would die quickly.

I recommend a good 850w for that.

But the fact I can run Furmark at the clocks mentioned with the 550w Kingwin with two GTX480s tells me the 500w is perfectly fine for one GTX470 no problem.

Will I have enough "overhead" room with this power supply? e.g. if for some reason all my components were running at max usage/power consumption, would I be stressing this power supply too much?

My concern lies with the +12V1@25A, +12V2@25A. Will this be enough to power a video card that already takes up 38A via two PCI-E connectors, and the i5-2500K (plus everything else)? Or when EVGA says "recommended 550W and 38A on the +12V", are they talking about the whole system?

No you won't, with that GPU and a 600w PSU, you will be 100% fine.

What Compuman said.

also note that manufacturers say they recommend a 550w or so wattage psu with thier card taking into account that the 550w could be a peice of garbage( putting out like 400w ) just to cover thier butts.

You are in Houston, head over to Microcenter and pick up a PC Power and Cooling 650w MKII for 59.99, Its a great deal at that price and will perform a little better than a Corsair 600w at the same price.

Antec True Power 500W should be available for a good price and should power that setup. For SLI you should get a quality 700+ W PSU.

Processor: Intel Core i5-2500K
http://www.newegg.com/Product/Produc...82E16819115072

RAM: 2x4 GB Patriot PC3 12800 (1600 MHz)
http://www.newegg.com/Product/Produc...82E16820220558

GPU: EVGA GTX 470 [requires 38A on +12V rail]
http://www.newegg.com/Product/Produc...82E16814130549

Drives: OCZ Vertex 2 (60 GB), 500 GB Seagate 7400 RPM, DVD+/-RW Optical Drive

I would like to buy a modular power supply as my case is the NZXT Vulcan which accomodates only microATX boards. What power supply can handle this job? Remember, the +12V rail(s) must power at least 38A for the graphics card alone.


==========
P.S.: How would this power supply fare? http://www.newegg.com/Product/Produc...82E16817341017


do you live far from here . . .
