Looking to buy this lot in the next couple of weeks. But before I do can some of you take a quick look at it to see if there's any major compatibility issues or other options worth looking at. Thanks. 
Intel Core i5-4670K 3.40GHz (Haswell) Socket LGA1150 Processor - Retail
ASRock Z87M EXTREME4 Intel Z87 (Socket 1150) DDR3 Micro ATX Motherboard
Corsair XMS3 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CMX8GX3M2A1600C9)
Samsung 120GB SSD 840 EVO SATA 6Gb/s Basic - (MZ-7TE120BW)
Silverstone TemJin TJ08B-E Midi Tower Case - Black (SST-TJ08B-E USB 3.0)
I'll be adding my current HD7850 and a couple of HDD's to this. Will my PSU be enough still? Or is it worth picking up a new one? PSU in question is a Corsair HX520 that's a few years old.
