I've had this problem for quite a while now, I've had the desktop power go off and then just start up again like its nothing . It just goes of randomly , iv noticed it seems to go off after extended use of the desktop. But when its not being used a lot 1-3 hours it will not just randomly go off. I know that the fans in my desktop are clean and temperatures all fine , i'm not quite sure what the problem is. I think the problem probably is go to do with the power supply or the power usage in the house, maybe taking up to much. These are the specs of my pc.
Graphite series 730t
Thermaltake Smart Power 750W 80 Plus Bronze
BitFenix Spectre Pro 120mm Black Tinted Red LED Fan
Thermaltake NiC F4 CPU Cooler
Intel 530 Series 120GB SSD
Seagate Barracuda 1TB ST1000DM003
Gigabyte GeForce GTX 770 OC Edition 2GB
Intel Core i5 4690K
G.Skill F3-14900CL9D-8GBXL 8GB (2x4GB) DDR3
Gigabyte GA-Z97MX-GAMING 5 Motherboard
The only solution that i could think of is having a back up power usp, or get an electrician at my house
A solution is much appreciated
 


Are you hooked up to a surge protector? Also do you have a spare PSU lying around to test to see if it's your PSU?

Thanks for the quick response! Nope im not connected to a surge protector and unfortunately i don't have a spare Psu but a purchasing one is int a problem. From my perspective a Psu is a quick fix not the best solution.
 


i recommend a surge protecter first, it protects your whole PC from shorting out and frying it's parts.

I dont know if it will stop that, but i recommend you also get a new PSU.

Here is a tier list for PSU's

Absolutely not. What is its let-through voltage? 330 volts? That means it does absolutely nothing until 120 volts rises well above 330 volts.

If well more than 330 volts existed, it did not power off. It was damaged. Unfortunately most recommend a protector only because hearsay recommended it. Most protector are recommended by people who have no idea what a protector does - who even ignore specification numbers.

Power cycling is determined only a power controller. That internal 'processor' even decides when a CPU is allowed to execute; allowed to boot and run a computer.

Foundation of computer is its power 'system'. Controller and PSU are components of that 'system'. To say more requires a meter, some requested instructions, and minutes of labor. An informed reply is only possible once those three digit numbers are provided. Then we can discuss why a power controller is powering off the PSU.

Surge protector is completely irrelevant to those symptoms. Most recommendations are not based in how it works or even in knowledge of a power controller. No useful reply can exist until relevant data (ie numbers) are provided. We know that power strip protector can even make computer damage easier. As made obvious by how a protector works - and its spec numbers.
