psu: fsp-group saga II 500, currently on an Athlon II x3 440 3GHz, amd 770 chipset, 2x2gb ddr3 1333, Radeon HD 5750 1gb, future replaced by i5 4460, H81, 2x4gb ddr3 1600, Radeon R9 285 2gb. can it handle it? it will not be OC'ed.
if you do get a new PSU make sure it is ATLEAST 80+ bronze. as for the PSU it maaay handle it. Rough calculation of minimum 380 maybe 400 watts.... So yes maybe, but can you give me a detailed list of the new specs?
