Need help with figuring out is this power supply any good.
Specs right now:pentium G2010,1x4gb ddr 3 1333mhz ram,geforce gt 630,samsung hd502hj 500gb 7200rpm,gigabyte h61m s2pv rev 2.2
I want to upgrade to:i5 3570(no k),2x4gb ddr3 1600mhz,RX 460 2GB GDDR5,hdd stays the same
The power supply currently is MS KY 550,i have read about it and it seems its a pretty sketchy PSU.Should i change the power supply,and if yes to what?I have had the MS KY 550 for 4 years with no problems.

Would a Raidmax RX-500XT be ok?
