Need a good, reliable PSU for new build

So this is my build as it stands:

CPU: AMD FX 8350

Motherboard: Gigabyte GA-990FXA-UD3

GPU: Sapphire HD7850 OC 2GB GDDR5

HDD: WD Caviar Black 500GB 7200 rpm 64 MB cache(I will get a secondary drive in a few weeks)

RAM: Corsair 8GB 1600MHz CL9 DDR3 Vengeance

DVD RW: Samsung 24x SATA DVD Writer

I have a CiT Vantage Type-R Gaming Case, which i know isn't great, but I'm not looking to overclock the CPU for a good while, and I'll update the stock CPU cooler when the time comes. I'm also using Windows 7 Ultimate.

I had my eyes on a Corsair Builder Series CXM 750W Modular 80 PLUS Bronze. But does my system really need all that power? If i could get away with a 600w Corsair, that would be great. Any help would be appreciated.

  1. Do you plan to SLI? Around 700 would be better with headroom if you plan to SLI, and overclock.

    620 watts is enough for a single card system, and Seasonic is one of the best power supply makers.


  2. I would recommend a Seasonic-built unit like this one:
    It is a little more powerful than you need, but should handle any upgrades you're likely to add.
    For the price, it's hard to beat. The Corsair "Builder" units are made by CWT, not Seasonic, using some inferior Samxon capacitors known for early failure. They aren't terrible PSUs, but with much better ones available, why bother?
    If you want something cheaper, get this Antec VP-450: which, despite the little voltage switch, is actually a modern, efficient design. It was built by FSP.
  3. This build is a massive upgrade from my current PC, which is a Intel quad Q6600, 3 GB DDR2, Geforce 9800GT system, so I'll be extremely content using the one GPU for the moment.

    I think I'll go with the SeaSonic M12II 750 Modular, as It will give me some head room, like you said, edogawa, for future overclocking.

    Thanks to you both for the insightful info on a brand I hadn't even heard of. And to Onus for letting me know of Corsairs inferior capacitors. Much appreciated.

    The better Corsairs, HX and TX, are Seasonic-built. Only the "Builder" series has the cheap capacitors.
    If you're not going to run multiple cards, 750W is considerable overkill. Even the 620W version it looks like we both linked is bigger than you need, but will support overclocking, and any single-card upgrade you're likely to want.
  5. Ah, ok! I see now. Didn't notice the other corsair models. I would go for the HX or the TX , but they seem a bit out of my price range. I had a feeling 750 would be over the top, that's the reason why i started this thread. Was a bit worried i might do some damage with the excess watts. So the 620w should do then? I will order asap to finish my build. Thanks so much. You learn something new everyday lol
