Looking to update my system.
i5 2400
2 x 4gb ram
2 hd
1 dvd drive

I'm looking to add a r9 270 either SAPPHIRE DUAL-X or XFX Double D R9-270A
to my system and the 2 power supplies I've been looking at are : XFX ATX 550 Power Supply and the Seasonic S12II 520 BRONZE.
I'm just looking to seem if 500-550 watts is enough power for this system.
