Ah, yeah. You're in need of a PSU if you want another card.

I think his PSU is 19A, but that still doesn't cover the cards at Furmark load.

You would be pulling 460w on your 12v rails if you completely maxed your CPU and cards.

A collective 40+ amps would do you.

I know it kind of sucks, but upgrading to serious PSU, while not "fun" or perceptibly performance enhancing, is one of the most important upgrades you can make.
Spend the money you would have on the card, on a quality PSU, then get a good card down the road.

Okay I saw http://ncix.com/products/?sku=58494&...y&promoid=1338 this. Seems like overkill but it cheap. Anyone had experience with this brand?

OCZ makes good stuff. Just know it's a refurb and this comes with only a 1-year warranty.

If you must order from NCIX, this looks like the best deal that would cover your build if you pushed it to the max.

55 CAD after rebate.

Single rail, plenty of headroom on the 12v rail, and a 5-year warranty.
