1600W is really over-kill for what you have, 1600W is really only needed when you have two big cards in SLI, but more so in triple SLI or cross fire. 9590 is a waste compared to the newer intel CPUs, GPU is alright, but you could have gotten a GTX 970 which is better in every way, and is more power efficient.
My setup:
i5 4690k
NZXT Kraken x61
MSI Z97-GD65 ATX
16GB Mushkin Blackline (I think thats the name)
ASUS Strix GTX 970 x2 SLI
x3 WD Black 1TB
x1 WD Green 2TB
x2 Samsung 850 512GB
NZXT H440 Black and Red
EVGA 850W Gold
x2 27 HP Panels I se'd
Chroma Keyboard
Steel Series Sensei Wireless
