Unfortunately, that PSU has two 6-pin and two 8-pin connectors, which would make Crossfiring 4850s impossible since each requires two 6-pin. An 8-pin does not fit in a 6-pin slot.

This is in the same price range (£2 cheaper) and has two 6-pin connectors, and two 6/8-pin connectors.

I also know it to be a good-quality PSU, I used it in a comp I built for a friend.

If you're interested, here's the difference:
An 8-pin connector


A 6/8-pin connector

Right! Ok thanks alot man! Pictures helped a newbie like me, I guess I better not go CrossFire because it'll probably bring the price up; changing the motherboard & PSU. I'll just stick with the 4890 for now.

Thanks alot for help and patience

em i think you are misinformed.

one 4850 only requires one 6 pin connection so two 4850's in xfire would only need 2 6-pin connections.

this psu will be more than enough, no need for 800+ watts

Oh, indeed I am O_O I should've checked more than one site.

However the TX650 only has one 12v rail, while the NorthQ I mentioned has four.

That PSU should be fine for xfire. I was leery of getting a Coolermaster PSU when I purchased mine, but it's been a great unit.

Corsair are just more popular and they are certainly great PSUs. However, Coolermaster are good too. I've been pleasantly surprised with my unit. It's really just what you want to go with. I'm saying, you will be fine with the CM even if it's not quite as popular with people on these boards.
