How much Watt PSU is enough for one card/

Motakuji · Feb 17, 2016

I'm buying a new PSU and I need to choose between 550w and 750w EVGA SUPERNOVA G2. Which would be the best for now and future.
CPU: Intel Core i7 2600 @ 3.40GHz Sandy Bridge 32nm Technology
RAM: Corsair 8.00GB DDR3 1600Mhz
MotherBoard: P8Z77-V LX (LGA1155)
GPU: ASUS R9 290 Core clock clocked from 947mhz to 1000mhz ( Arctic Accelero Xtreme IV cooler)

Probably 550w is enough, but I would choose Seasonic 620W just to be safe

the 550w is enough power for the system.

750w is just about enough for 2 of the gpu's if you ever wish to run xfire of them. if they are close in price i'd go for the 750w one just to stay ahead of the game. if you don't plan on xfire in the future or the price is much greater, then the 550w unit is good enough.

WetysCZ :

Which model?

For future go with the 750W. That also gives the added benefit of less stress on the PSU at lower loads now so it will most likely last longer. Then the power is there if you need it in the future.

Good choice either way - a Tier 1 product.

cheaper one - Seasonic S12II-620 620W
more expensive one - Seasonic SS-620GM2 Evo 620W
