    850W PSU recommendation please

    Hi,

    I am currently considering the following PSUs:

    1. Corsair RM850i
    2. Corsair HX850i
    3. EVGA G2 850W
    4. EVGA P2 850W


    Corsair has the Corsair link but I am not sure how useful it is...Any one has any experience?

    Thank you very much.

    Can't speak for Corsair link, but the EVGA G2 PSUs are very highly regarded as incredibly well built units, and I would assume that carries through to the P2 Platinum efficiency series.

    Corsair's higher end PSUs like the RM series are supposed to be well built too, just corsairs lower end ones such as the CX apparently aren't too great. IIRC EVGA does 10 year warranty on theirs.

    EVGA would/will be my next buy. They are basically Superflower Leadex Gold/Platinum's with a different fan, no tacky leds and a whopping 10 year warranty. EVGA also has a UK rma centre now.

    Do you actually need 850w though? Are you running multiple gpu's? If not then a quality 550w psu is enough to power just about any single gpu setup even with overclocking.

    Re: 850W PSU recommendation please

    if based on the list i will go for EVGA G2 (SuperFlower). i personally suggest always go for Top Tier 1 PSU

    FYi, Seasonic G-550W V2 can't even able to support i5-4460 + GTX970 so i ended up with Seasonic X-750 KM3

    i bought G-550 on Dec '14, sold on April '15 & the user never complaint a single issue with his rig.

    my gpu ASIC quality is showing 79.8% http://www.techpowerup.com/gpudb/ind...13C2-107D:2762

    High ASIC "Quality" (Leakage) = Lower operating voltage, larger current draw, hotter, less energy efficient (due higher losses)

    Low ASIC "Quality" = Higher operating voltage, lower current draw, cooler, more energy efficient

    If everything is working without fault then it can more than support it.

    Agreed. I run a 4670k and a 760 (much more power hungry than a 970) on an XFX Core 550w, which is effectively a rebranded seasonic S12 550w, built by seasonic to similar spec and I've had no issues what so ever.

    Sorry but FYI, if your pc didn't work with the Seasonic G550 then you did something wrong. Your pc is much more power efficient than mine (see my system spec to the left) yet mine only pulls a peak of 452w at the wall and even then only if I run IBT and Furmark both at the same time. The Seasonic G series 550w with it's single 12v rail of 540w would easily power that. With your pc fully stressed I doubt if you would pull more than 250-270w at the wall.

    Thread revival allowed, as the question looks legit.

    BOOtPus.. what is your system build plan? CPU? GPU etc?
