Suitable PS for a Core i5 without SLI...

Hi there.

I'm intending to get myself a Core i5 with a small Gigabyte P55-UD4 mobo. Nothing special. GTS 250 Vcard, Xfi Audio, few HD's, Blu-ray and DVD-RW.

My question is: How big'a PS do i need to buy for this stuff? Would 550W be enough? Should i go for more power?

If so, what would you guys recommend.

Thank you in advance...

  1. 550W PSU is more than enough...Just make sure you get it from a high quality manufacturer...
    Even an Antec EA 500 would suffice and can handle even more powerful graphic cards...
  2. The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the 12 volt rail(s) can easily handle a system with any single video card made.

    Corsair, PC Power & Cooling, and Seasonic are brands with a reputation for high quality psu's. They consistently earn high marks in Technical reviews. They are stable, reliable, and come with a 5 year warranty. The Antec Earthwatts EA-500 mentioned by gkay09 is also a very good power supply.
  3. I'd love to get one of those "silent" models. I've been thinking 'bout the Cooler Master Silent Pro 550W one. Is it any good?

    Thanks again for all the help.

    For specific recommendations for silent quiet power supplies check out their lists (There are two lists):

    I'd recommend the Corsair HX 520 from their second list:
