It lacks some of the most basic failsafes

To quote mikeaj it's so cheap it doesn't have APFC

Is there not a single one from the list you can find in your area?

If it is a decent PSU I would not hesitate. Ran 2 x 5870's in CF on an i5-570 with a Corsair 650TX. Still using the same PSU years later.

So I got me a power meter and it tells me that my rig, with one HD 5850 at 100% load, uses 222W
Minus the card it uses 50W idle and 88W with the cpu maxed out.
222 - 50 = 172 for the HD 5850.

Two of those plus the rest of the rig maxed = (172*2) + 88 = 432W total max load.

Given the right amps on the 12v rails, wouldn't a 550W PSU be easily OK for that setup ?

If what the power metter tells you is right and its 432 then a 550 would be fine just make sure to find one with enough amps for 2 cards

Ah you want to compare the Danish with the UK market ?
First stop for me always ebay - let's see.... used Antec for £30, mm, would prefer new with a warranty....powercool £40 but not recommended.... OCZ ZS slightly used £43.... brand new OCZ ZS £50

Prices are only slightly below 600W - as may be expected.

What are Powercool X-viper like ?
