PC wont turn on unless unpower....

[revaven]

Hi guys,im getting trouble with my pc. It is new (1year). And im bad in ENGLISH but ill try my best to write about my pc.
My pc wont turn on when i press power button. I have to unpower it from the electricity on the wall about 30s or 2mins. Sometimes it doesnt work, and i have to unplug the power cable of the PSU then plug it in gain, or switch the power button of the PSU of about 1min Off then On again. But after it turned on it can run well, i can play games like BF4 or GTA V all day without any problem ( i mean no suddently shutdown or restart).
PC:
i5 4670k (4.2)
Asus z87 pro
Corsair Dominator Platium 2133
MSI 760 4
Samsung 840 EVO 120
WD 1TB
Cooler Master V1000 psu
I search on internet and see that seems the PSU is the problem. Before the CoolerMaster (CM) PSU i used Zalman 700-GV which is whinning alot underload. But no problem to turn on my PC with Zalman psu. Only CoolerMaster psu has the problem.
I sent CM psu to the store for waranty and check if that was a failure psu. I back to Zalman psu for a week while waitting. When using ZM psu anytime i wanna turn my pc on it will turn on well.
So after 1 week the guy at CM store checked and said that my CM psu was perfect, nothing wrong. OK i back with CM psu again. 1st day OK, 2nd OK, 3rd OK, and BANG, pc wont turn on again. Again i back with my old tricks upower, unplug, switch power button on psu......so annoying. Cant take it anymore. Im here to ask if anyone has same problem with me or someone who knows exactly that the CM psu is the problem and i have to replace other psu or any solution to fix this problem. If have to buy a new psu im thinking about Corsair ax760.
Sorry my bad ENGLISH hope u guys can understand what i tried to say.
Thanks.

Hi tea. As i wrote above. My pc is built almost 1 year. And the CM psu came after my pc about 2 weeks later so CM psu's old is same. Yea the CM is better than my other psu a lot but the ZM worked like a charm, thats crazy lol. Yes im not suprise that the guy at the store lied. Thank for ur reply. I think ill wait for some more answers to see if i need an other new psu. 🙁

With what you say you'd think it's the power supply.How did the store test it?

Could be that at start up something can trigger a safety measure with the cooler master when the zalman lets it slip by.Doesn't mean the cooler master is faulty,just very sensitive to some kind of power fluctuation.Could happen at powering down too,since the problem arises at start up -> taking the power off completely resets it.

See if you can swap the cooler master for something else? Or try and sell it,buy something else.

The other possibility is trying a rma from the cooler master and see if a new one will be less sensitive.You could ask at cooler master to see what they think.Look for "Tech Support" ,probably email,but that up to you.

Sounds like 2 possibilities in my opinion. Previously mentioned the PSU or it could be the plug socket itself... Have you ever plugged a PC into the socket, have you tried charging a phone on the socket?

Yes my pc is plugged with a socket which plugged from the wall. And i do the same with the ZM psu as well, same socket even same spot but ZM worked CM not. Yes sometimes i charge my phone on the socket. Ill try to contact the store again and see what they say.

Ill try to contact the store again and see what they say.

Yep try and if they don't want to assist have a go at cooler master support itself.

Again at the store, they use it on an other pc and it worked. No idea.

[ have a go at cooler master support itself.

See what they think about it.Maybe they agree with me and maybe they can convince the store owner that an rma is right or can assist in another solution.
There is a CM representative here,maybe he/she can assist.You could ask one of the mods if they know how to get in touch.

A return merchandise authorization (RMA), return authorization (RA) or return goods authorization (RGA) is a part of the process of returning a product in order to receive a refund, replacement, or repair during the product's warranty period.

Do you speak French?
I have a similar problem, it would only happen if my computer was shutdown for too long. I did an RMA but I still got the problem.
I want to know the solution if you find one!

Hi. Sorry i dont speak French. How long that too long ? My pc will not turn on after shutdown about 10-12 hrs or just after shutdown. U said that u did an RMA and still got same problem. U meant CM sent u an other new psu and u still got same problem ? My best solution so far is buy an other new psu. Not CM lol.

I replaced the CM with a Corsair ax860. All good so far. PC will turn all anytime i wanted. And i noticed that with the Corsair psu when i shutdown my pc the shutdown icon shows up and spinning like 2s then pc off. With CM psu that icon wont stay 1s and pc shutdown like some1 unplugs the power cable. Shutdown looked not normal.
