Just built a pc about a week ago, it has an MSI 990FXA mobo and a EVGA 750B psu. I was surfing the Internet and it just crashed. The pc shut off and when I turn it on clicks for a my front blue led fan lights up for a quick second and starts to spin and then nothing. I don't know what to do, I don't know much about computers. It took me forever to build it and now I'm scared that I spent all this money and it will never work.

EVGA makes good power supplies in my experience. You don't need a gold rated power supply to run a simple system. I think he might have some loose cables. OP, unplug it from the power and check to see that all wires are fit securely in place.

Gold rating has absolutely nothing in relation to the quality of a power supply. EVGA and Corsair both make some of the best and worst units, this being one of the latter. The power supply is what failed here, and if he wants to get his machine running again, he needs to replace it.

He should refund it.

It's the power supply, 100%. This happens all the time to people, and the clicking noise is from the power supply.

What are your full system specs so when you get your money back I can recommend you a high quality unit? Chances are you don't need a 750W unit and will be fine with a 500W.

It sounds like the power supply is detecting a fault within the system. The power supply may be fine. The power supply also has fault protection circuits that shut the system down when it detects a short (like a breaker). So before replacing the power supply check for lose parts or screws within the case (or loose connections).

The PSU also contains thermal protection that can cause this. This is less likely. But it is also easy to determine. The next time it fails unplug the system (and discharge the capacitors by depressing the power button for 30 sec.) and place your hand near or on the power supply. Then determine if it is hot. It should not be hot under normal operation.

Not sure how the power supply would blow since it wasn't under load, but he does get power since the fans spin.

[strike]Not true, the 290X will never draw in more than 400W of power under the worst stress test you can think of, and then the rest of the system leaves his build at about 550W of power draw under worst case absolute scenario. It'll never even reach that, it'll be more like 500W, which is still a lot of stress for this PSU but perfectly within specification.[/strike]

Edit: Oops Terry, I thought you said doesn't meet criteria. My bad 😉

@Kevovaz: It's still a power supply issue, it happens to a gazillion of people. If your computer crashes and then blacks out, then you turn it on and it turns off after a split second, it is the power supply.

You can check the power supply most simply by switching it out with a PSU known to be working. You can also take it to a PC Repair shop and have them test it. After the power supply, it gets more complicated to determine the cause of the problem. Any of the components can cause a fault. Look for burn marks or components that no longer work.

Not a problem. My typing is far from perfect.

It was my reading, not your typing :)

One of the main problems in a newly built system is just something dropped within the system like a screw. If it rolls onto a motherboard contact or exposed trace, it will cause a fault.
So just looking for something random inside the case. Tip the case and see if anything rolls to the side. And make sure the connections are secure.

The $120 is a bit of a problem right now. The prices have just gone up. Here is another good model at the price.

SeaSonic M12II 750 SS-750AM2 750W ATX12V / EPS12V SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Full-modular Power Supply New 4th Gen CPU Certified Haswell Ready

Above all don't pick one of the Corsair CX series. they are cheap PSU for a reason. You may have to look for a sale to get a good model in your budget. Newegg has PSU's on sale all the time.
