hi all! i wanted to ask you guy's if the power supply that im thinking of going with is decent, what i'm looking at is a: RAIDMAX HYBRID 2 RX-730SS, it's not 80plus rated but has other nice features like being modular and crossfirex support. i'm building a gaming rig with a hawk edition msi 7870, 8gb of ram, i5-3570k, and a z77 motherboard. this psu's counterpart: RAIDMAX Blackstone series RX-700AC is 80plus rated but is less powerful and not modular. i really just want the best rather cheap psu i can get, should i buy a less powerful one from a different brand, or will both of these be fine!? thanks for your time!
