i will make this quick, my pc dies some minutes after i start any game and i have no clue whats causing it besides that it´s not temperatures and that i have to restart my psu in order to get the pc back running.

my gpu never goes above 70
my cpu is always at 50

specs:

gpu: msi gtx 770 2gb gaming
cpu: intel core i5 4440 3.1 gzh
psu: corsair cx 750m 750w bronze modular
ram: adata xpg 8gb (2x4gb) ddr3 1600mzh
mobo: msi z87 g-45 gaming
hdd: seggate baracuda 1tb hdd 64mb 7200 rpm
chase: nzxt guardian 921 rb mid-tower

known issues: some cpu-pins where broken but i bent them back, this is probably not the problem since it´s been like that since i built it and it´s never been a problem

if it is that then there should be no problem, i have a warranty so i´ll just turn it in and ask for a new one. are there any other psu that i should get instead? i did buy the 750w psu to uppgrade to sli so it would be quite meh if i had to buy a new one...

cx psu are average psu made for home office use not for gaming and overclocking yes rma the psu ......if u thinking about future sli then 750 watt would not be enough at least a 850 watt or a 1000 watt for better headroom ......gtx 770 is similar in power consumption as gtx 780 both requires 42 amps in single rail...

Have you had the overclock the whole time? Could be an unstable OC.

when i bought that psu i thought it would be enough, i mean it´s 85% of 750w so it´s 600w a single 770 takes 230w my cpu takes 85w and the hdd v-ram and mobo consume 50 at most so 230+85+50=365w 365+230=595. it should be enough to run two 770 or at least handle the one in my build right now )=

Like I said I have two HD 7950s on that PSU. It is capable of running those, but it could be a faulty one.

two 7950 consumes 60w less than two 770s

My HD 7950s are overclocked pretty high, and are the versions that use a 6 pin, and 8 pin instead of two 6 pins. Also you only have one GTX 770, so my point is it is not a high quality PSU, but it can still get the job done.

i guess not, there are some holes but they where clearly not enough to provide air for my psu.
