More about suitable build
  1. You're correct. The Corsair 400CX will have enough of the most important +12V amps to cover your needs with some to spare for upgrades & overclocking. Corsair 400CX review

    It's the same PSU that Bit-Tech recommends for it's Affordable All-Rounder system in the Bit-Tech DIY building guide.
  2. Thanks for the quick reply, that good to know as I do not want to get a PSU for it to break all the components inside.
  3. Yes you need a minimum of 21 amps on the 12v rails. You actually have 30 amps.
    Room for expansion.
  4. That's good to know thanks
