What is the best PSU for handling 2 Quadro K6000s?

Bee P October 11, 2013

I’ll be getting 2 of these: Quadro K6000 graphics cards, and I’m wondering which of these PSUs might be best at handling them (and why):

Rosewill 1600W Intel Haswell Ready 80 Plus Silver Modular Gaming Power Supply HERCULES-1600

LEPA G Series 1600-Watts ATX12V/EPS12V SLI Ready Crossfire 80 Plus Gold Certified Full Modular 240-Pin 1700 Power Supply (G1600-MA)

Coolmax 1600-Watts 80 PLUS Power Supply with Active PFC, Silver ZPS-1600B


Rosewill 1300W 80 PLUS GOLD Certified Power Supply LIGHTNING-1300

EVGA SuperNOVA 1300G2 ATX12V/EPS12V 1300W 80Plus Gold Power Supply 120-G2-1300-XR

    I agree with Jan and the others. No need for 1600W. You won't be wasting power (PSUs produce what's needed, rather than work at "full tilt" all the time), but beyond a margin of about 30%, there's no need for a bigger power supply. As for the makes and models, anything in this bracket would do the job just fine, it's more a matter of specific features and personal preferences (modular connections, fan orientation etc) than declaring one "better" than the others.

    The Quadro K6000 has a TDP of 225W – so with two of them you are looking at 450W plus the other components (~150W). All together any 800-1000W should be sufficient to run them even at full load.

    Seasonic, Cooler Master, Enermax, Corsair … make your pick (80plus bronze/silver/gold optional)

    I agree with the other posts made here: http://forums.pcworld.com/index.php?/topic/161196-best-psu-for-handling-2-quadro-k6000s/. Seasonic is one of the top rated brands for power supplies, and you shouldn't need more than 850W of power (depending on the rest of the system and setup, which would make for even better suggestions). If you wish to have more power than suggested, go with up to 1200W because most likely any higher would be a waste. If you plan on adding more (quad quadro setup), then 1600W may be called for, but the 850W-1200W Seasonic should be sufficient.

    you can choose the one you like most perhaps best with the one certified 80Plus Gold.
