PC randomly shuts off and wont turn back on until PSU replugged

[Contana]

So, I've read stuff on this page about the same problem, but those people mostly had an old PSU, but I've bought a new PC about 6 months ago and I've had such problems well since i bought it, but very rare, like maybe once in 2 months i thought it just might have been a software problem or so, but it started to be more frequent.

Basically, the PC can be idle or at load, but it will just randomly shut off and sometimes won't turn on until the next day no matter what i do. Once i managed to run it after replugging the PSU about 50 times, and then i had to run a prompted memory check because i had some memory sync error when trying the " restore to a previous point " option that windows gives you. I'm wondering what's the problem ? RAM ? PSU ? MBO ? I just have no idea since it's all new components and I've connected them myself and checked 2 times.

PS I've had some BSODs like once or twice a month saying something about memory if that helps any or may be connected

I've got the Corsair 600GS PSU,
1600 MHz 8 gb corsair vengeance RAM
z87 G43 MBO.
GTX 760 GPU
i5 4670 CPU
1tb WD blue HDD

in my experience when a psu refuses to power on after a random off it means 1 of the protection circuits have tripped.
which could be caused by, dirty power going into the psu (ups will often solve this as it acts like a buffer cleaning up power spikes)
or the psu itself is retaining current in 1 or more bad caps. (check the motherboard led's if they go off instantly instead of fading out after 20-30 seconds it could mean bad caps in the psu) only option is replacement...

the gs range aint the most stable or well made psu. but thats not to say its junk. they have a fail rate of about 5% in the first year which is pretty much the average. rma is also a bit of a bitch with corsair after the first year of warranty. in some cases they have asked for P'n'p to be payed for the return and its not cheap... i dunno if they reimburse you (they should) for it either...

Sounds like a PSU problem even still, I had a similar problem with a clients build once, PSU had a bad cap... Do you have a spare PSU around just to test? If you don't, I highly recommend having a spare on hand for situations just like this.
