    Post Need some help choosing among those PSU please

    After long research and what I felt like somewhat hijacking the RM750 thread I thought it would be better to make a new one to leave the other more on-topic, as on-topic as it was at least.

    Anyways, I'm running an FX-8350 with a factory overclocked ASUS DC 2 Top R9 280x, plus the usual amount of a couple SATA drives, a DVD one and fans from the NZXT Phantom case.

    I narrowed my choices down to these PSUs for now, listed with their prices in my currency and roughly converted to USD to give a comparison:

    Cooler Master V750S (1055 SEK = 160 USD)
    Cooler Master V700 (1200 SEK = 185 USD)
    Cooler Master V650 (850 SEK = 130 USD)
    Corsair RM750 (935 SEK = 140 USD)
    Corsair RM650 (830 SEK = 125 USD)
    Seasonic X-650 (1200 SEK = 185 USD)

    Silence is very important to me, but I also want it to be built to last. Obviously with a budget that was actually up to 1000 SEK (150 USD) I know I have to compromise somewhat.

    Thanks in advance for the help.

    PS: I would potentially put the Corsair TX750M v2 for 1040 SEK (155 USD) on the list as well, but am not sure if there even is such a product. It's listed in the price comparison I'm using, but google searches only result in a v2 of the TX750, not its modular variation.

    Only one R9 280X? Or should the PSU be able tot power two?

    For two the CM V700, for only one, a good ~550W.

    Only one, I doubt I'll go crossfire at any point. Regarding lower power units I was actually afraid they'd be too weak, for now or the future. I'd prefer to have some spare so to speak. Also, I was under the impression that lower usage of the PSU results in better noise levels, efficiency and longevity.

    Nah, 550W is plenty. Even 450 would cut it. I'd get a Seasonic G-550 if that's possible.
    No wonder it doesn't work! You installed the coils backwards

    The 280x is a re-branded 7970ghz.
    So 250 watts is plenty for anything besides furmark.
    the amd fx-8350 is good for 200 watts with the board and memory. (at full load benchmarking)

    Yeah, for any reasonable use 550 watts will run it fine. with high OC all around you might be hitting 100% and some fan noise. (of course if you are running the gpu and cpu at 100%, the psu fan will be the least of your worries.

    The coolermaster v700 is a great choice, if a little over your budget.

    That one's at 932 SEK (140 USD). I'll think about it, thanks.

    Indeed, on both the GPU/CPU at 100% part and the V700.

    I'd think rather too much than too few, but will keep the lower wattages in mind as well. Guess I'll have to wait a bit longer for a new one with potential new options...
