That PSU will easily work with those components with no problem and PC Power is a quality brand. Make sure that you choose a case that will handle it.

Were you wanting to run two of those cards?

The Matrox does not need the power connector from the PSU, it does not need that much power.

The PSU you mention is a very good one, but it's probably more than you need.

Yes, eventually two. What do you recommend? Thanks a lot!

I do not see the power requirements listed at Matrox. I do know that PCI-E is limited to 150W... So that is a max of 300W between the two cards.

This PSU will give you many years of worry free operation, and should power any additional devices in your case with ease.
