Ive got a SuperFlower Golden Green HX 550W "80 Plus Gold" Power Supply and was wondering if it would be ok with a r9 290 oc. The rest of the system is ...

Asus Z97-K - Devils Canyon Core i5 4690K Bundle
TeamGroup Vulcan RED 16GB (2x8GB) DDR3 PC3-19200C11 2400MHz
Samsung 250GB 850 EVO SSD 2.5" SATA 6Gbps
also a sata hd

Thanks in advance
