What PSU should I get for my graphic card and my system ?

Motherboard : H61M-D2P-B3
Processor : Intel Core i5-2400
RAM : 8 GB
Graphic card : Gigabyte hd 7770 OC

Is 500watt (cooler master) good PSU for my system ?

  1. Plug your system parts into pcpartpicker.com. It will calculate estimated power requirment. Multiply this number x 2, then round up to the next PSU. This is a guideline not a rule.

    Good brands: Seasonic, Corsair, and PC Power and cooling. Cooler Master is not in the top teir. Will it work, yes. For about $20 more you can buy a better PSU that will last longer and provide more reliability. You'll vote with your cash - a little homework will go a long way.

    Good Luck !!
  2. Cooler master psu's can be iffy on quality.
    Look for a tier 1/2/3 unit from this list:

    500w is sufficient for your 7770.
    This chart assumes a nominal complement of other devices:

    good advice...antec xfx or seasonic is the way to go.....and no...dont use pcpartpicker to calculate psu usage...thats asinine.
  4. best psu for you is corsair cxv2 430w as it is more than enough.if you want more headroom for future upgrades then get corsair cxv2 500w or seaonic 520w
  5. I didn't find XFX or seasonic or antec..... All I found was cooler master and raptor 500w
  6. which country you live?
  7. In Egypt ..... And those are the PSU's I have found in stores ( Cooler master - Raptor - Gamma - Skybox ) what is the best PSU ? ( I want 500watt )

    Post a link to where you might buy parts
    Do not buy a cheap quality psu. It will not deliver advertised power, and if it fails, it can damage anything it is connected to.
  9. Like I said all I have found was ( Cooler master - Raptor - Gamma )
  10. well raptor 500w seems fine at amperage ratings
