Hi Guys... just a simple question...

Im looking to upgrade my system within the coming month.

It will probably end up:

  • Intel Core i5 750 (Try to OC to 4GHz)
  • ASUS Maximus III Formula
  • 4GB G.SKILL Ripjaw 1600MHz
  • Radeon HD 5850
  • 1 x DVD Drive, 2 X HDD

What i'm wondering is if a Corsair HX 620w will be enough to power this system..

Currently I have a fairly Cheapo 700w PSU... that most likely doesnt meet it's specifications.

The reason I chose the 620w is beacause Corsair is a good PSU manufacturer and the red and black asthetics will match the rest of my components / wc loop / case

That PSU will easily be able to run two 5850's in Crossfire while overclocked as well as your CPU.

If you have classifieds access, there's a HX620W for sale right now... Shipping to the UK might be tricky, but might as well try, right?
