I have an evga 500w psu with 40 amps,
my question is will it safely run an NVidia 960 gtx and an i5 4670, I don't plant to overclock,
i was also wondering how many watts the motherboard uses,
my system is as follows
msi h87i mini itx motherboard
i5 4670
msi 960 gtx
8gb ddr3 xms3 1600
3tb Toshiba hdd
120gb ssd
mini itx case thermaltake core v1
evga 500w psu

i just wondered if i need another psu to play it safe
