  1. Reference here:

    Normal 7850 requires a 500W psu with 21 amps on the +12V rail. I'm guessing OC edition might need 10% more, so a 550W or better psu with at least 24 amps on the +12V rail should be safe.

    Your ok with the psu youve got! Unless you have a half decent graphics card which i didnt see listed in your specs mate. If your just using the onboard graphics on your cpu then your fine.
  3. For a single graphics card like 7870 you'd be fine with a xfx pro 550w http://www.ebay.co.uk/itm/XFX-Pro-550W-Core-Edition-PSU-Bronze-Power-Supply-P1-550S-UKB9-/150971230719?pt=UK_Computing_PowerSupplies_EH&hash=item23269629ff £52 is a good price! If your wanting to crossfire then id get a more powerful psu , but the xfx will be well ok 4 what youe after.
  4. Great this psu has a lifetime warranty right? i dont know if i will get this psu since i live in india. i will have 2 check with shop dealers.
