Guys, I wanted to know what would be a recommended PSU for this machine, even because my computer is restarting everytime I play games, and it isn't overheating, my pc does not pass 70 ° C(158°F) in any game! Please help me !!
Video Card: AMD R9 270x
Processor: Intel 1150 core 44600 3.2 GHz
Motherboard: Gigabyte Intel G1.Sniper B5 socket 1150
HD: SATA3 1TB
Memory RAM: 1x8gb
PSU: EVGA 500watts 80 plus
peak of the GPU: 75°C(167°F), peak of the processor: 72°C(161,6 °F)
the CPU is Connected directly to the socket!!!
Does anyone have any idea?
 


Which one I pick then ?

Corsair ATX CXM 550W 80 Plus Bronze
or
Corsair 550W ATX RM550X 80PLUS Gold
I would want the cheaper one, but you're telling me that isn't good right ?
 


Okay, thank you! Is there any other model that you can recommend me ? Just to compare
 


Thanks man, I'll analyze the options and see what I do o/ cya
