Hey Tom's! I was wondering if a 750W PSU would be good enough for a dual SLI 770 setup for the future. Is there any reason to get an 850W PSU? Thank you! I plan on overclocking a tad for my CPU and my GPU(s), thank you!


  • GPU: EVGA GeForce GTX 770 2GB Superclocked ACX

  • CPU: Intel Core i5-4670K 3.4GHz Quad-Core

  • CPU COOLER: Corsair H100i 77.0 CFM Liquid

  • MOBO: Asus MAXIMUS VII GENE Micro ATX

  • STORAGE: Samsung 840 EVO 250GB 2.5" SSD

  • CASE: Corsair 350D Window MicroATX Mid Tower

  • PSU: Corsair 750W ATX12V / EPS12V


  • Thank you!

    eh, 750w is enough power, but you need to have atleast 2x 6-pin and 2x 8-pin/6+2-pin connectors, and if it is from corsair, stick with the ax, axi, gs, hx, hxv2, tx, and txm series.

    no no no, a 770 takes 230 W, so thats 460w, plus 84 for the cpu, add 10 for an hdd, 5 for an ssd, a couple for the ram, some for fans, the mobo need some, and the psu has some inefficiencies, but it all totals to about 600 watts.

    Which corsair is it? 750 Watts will be fine. Just don't overclock anything if it is the CX, CS or RM 750.

    No that won't be enough - You'll need something like a 1000W so tha you have room to expand and over clock as well...try out new eggs power calculator....it should give you a good estimate

    I should have mentioned I used the watt calculator on PCPartpicker, and with dual SLI it came out to be 659W, so I was thinking going over 100 (750W) should be fine. But I mean hey, this is going to be a new build, I could go big lol

    Hi Brooks G
    Yes 750w is enough for your sli
    for a fully modular psu with high grade japenese capacitors

    or

    Hey Micky, thanks for responding so fast!

    I've built a few PC's before so I'm tired of the non modular PSU's lol,
    I'm thinking bout going semi/ full (for a good deal). Is XFX a solid company?
    I haven't gotten a card or gpu from them, I know seasonic is very reliable.

    Also I see you didn't recommend a Corsair PSU, is Corsair not as strong in
    their PSU's as compared to their Cases, CPU coolers, Ram, etc?

    Thank you!

    xfx is also made by seasonic and has high grade capacitors
    Corsair do make quality psu's but The TX , HX or AX range are the best

    XFX is better priced than Corsair but the HX 750 should be fine for the SLI setup.
