Hello everyone.

My PC crashes at random times, while playing a game or just watching a movie, without any warnings or blue screens. Like if there was a power cut. Then it just restarts with windows saying that there was a bad shutdown and whether i want to boot normally or boot in safe mode. Some times after it crashes it tries to boot and crashes again for many times so i have to close the PSU and open it again. I have tried every stress tester and benchmark available and everything works perfectly. CPU never over 60C and gpu never over 65C under full load. On the contrary tho, when i run furmark the PC crashes after 1-2 seconds, with no reports, as it does when it crashes randomly. (some times when playing a game AI Suite II reports low voltage on 12V but the PC keeps working normally. after testing and seeing the PC crashing with furmark i think there is a PSU problem.) Any ideas/suggestions?

The PC components are:
Motherboard: Asus P8Z68v-lx
CPU: intel I5-2320 (stock settings, cooled with Corsair H100i)
Ram: Kingston 4GB KHX1600C9D3B1 x2
graphics card: Asus ENGTX 570 Direct CUII (came a little bit overclock, never manually oveclocked)
sound card: Asus Xonar STX
SSD Ocz Vertex 4 128GB
HHD Caviar Black 1TB
PSU: Hantol 800Watt
Case: Coolermaster Storm Stryker

Thanks a lot for your time.

well, you not have to burn your wallet for a decent power supply,
something like EVGA 100-B1-0500-KR (http://pcpartpicker.com/part/evga-power-supply-100b10500kr) is good if you really tight on budget. just cost you $30 after massive discounts and rebates..

or SeaSonic S12II 520 / M12II 520 Bronze is very good quality PSU..almost twice the price of evga 500w, but give you better result and durability...

About evga supernova 650, well, based on FSP aurum 650w. This one is excellent psu. if you can afford it, grab it.
It was a gift and i kinda stuck with it... I was planning to change it but PSUs are pretty expensive 🙁.

After some research, what do you think about EVGA SUPERNOVA NEX650G GOLD POWER SUPPLY 650W ? Also i liked the corsair AX760 but it is double the price and some say about coil whine.
