GFX upgrade - PSU enough?

Hi guys

I just wanted to ask if my current PSU which is powering my current computer (specs below), would be able to run a HD5850?

Current specs:

Motherboard: MSI P43 Neo-F
Processor: Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz (2 CPUs), ~3.0GHz
Memory: 6144MB RAM
Hard Drive (1 IDE & 1 SATA): 330 GB Total
Video Card: HIS ATi Radeon HD 4850
Sound Card: Creative X-Fi Xtreme Gamer
PSU: Hiper 580w (Version 2 - not the ones that blow up?)

Hiper 580w has been solid, and has not failed me one in this rig, contrary to the blowing up problems.

It has:
Rated Wattage: 580W
Peak load: 630W
ATX form factor: 2.2
+12v 1: 1A - 20A
+12v 2: 1A - 18V
Average Efficiency: 76%

On :
My recommended minimum PSU wattage is 274W (with GFX as HD4850)
My recommended minimum PSU wattage is 264W (with GFX as HD5850 - seems more efficient?)

Would this be enough?

More about upgrade enough
  1. 4850 and 5850 use bout the same power
  2. If your PSU runs 4850 well then it will also run 5850 well.

    I would say go for it :)
  3. Ok, thanks for the comments =]
