Will it work? Yeah, it actually has 2 of those connectors on it, 1 6 pin and 1 6+2. THat said I hope you don't own that PSU, its a cheap piece of junk.

Its rated wattage is certainly enough, but such cheap power supplies can cause problems. Buy at your own risk.
I'm a noob to PC Gaming, what PSU would recommend for less than $50 that works with the PowerColor r9 380? Please help
$50 is a bit too low to do it, but get either of the above, they are only a little more.
EDIT: Just found this killer deal, a little overkill but only $54 after rebate
