Hey i am building a gaming PC and every little penny i save can help ;) so i am going to keep my GPU from the current PC and was wondering if i can keep my PSU too
(not planning to overclock)

PSU : SSP-550RT 550W ATX12V v2.31,EPS12V v2.92 80Plus

GPU : evega gtx 650 ti boost sc 2g


Motherboard : haven't decided yet would like to hear suggestions tho :)

CPU : i7-4770K Haswell

not going to spend money on cooler will use the fan i get with my i7

Hard drive : WD 500g Black

SSD : SSD Samsung 840 EVO Series 120GB 2.5" Sata 3

Memory : 8g ram ddr3

in addition i will have x4 120mm led fans

Case : Antec Three Hundred


the main question is if my 550W PSU can handle it i would also like to hear suggestions for motherboards !
and if my 150MM wide PSU can fit in the Antec Three Hundred



it is the first time i build computer myself i hope i made good choices


Thanks !
