but is it enough to run the graphics card and gpu?
Thx for the best answer, but I'd be remiss if I didn't jump back in
for this question.
I think you are asking for trouble(and ko888 is suggesting) with that PSU,
it's the worst component in your system to gamble on quality. Remember when a
faulty/underpowered PSU goes it can take other components with it.
If you are low on funds then start saving for an upgrade.
