Do you already own the Coolermaster(aka Crappermaster)?
If not choose another brand. However, even tho it's a
bad PSU, it does deliver it's rated power, it should be able to handle either of those cards.
No, I do not own it already, but I live in Venezuela, a country where the only certified PSU's I can get are Coolermaster and thermaltake which is too expensive here...
So I guess I'll stick with Coolermaster, thanks for the answer!
