I bought this custom built pc three weeks ago. Yesterday, I doesn't start up. After I have pressed the button, nothing happens. I switched off the socket and the power supply, turned it back on, and it worked. But later, I want to turn on my pc again, it won't turn on. No matter how I turn on the switch, switch off the switch. It just won't budge. Then I left the power switch of the power supply to O. Today, I switched the switch back to I then it turned on. I am thinking might be the power supply's fault. Also, I have done some testing yesterday, my motherboard's light was green when the computer won't turn on. I am not sure if my power supply's fan was running. Can anyone help me with the problem. (Sorry for my bad English)

Check the power button jumper on your motherboard and make sure it is in all the way / properly on. It's easy to miss a pin and put one end on with the other hanging off the bottom.

I just glanced at a review and specs of that PSU - It only gives 44 amps on the 12 V rail, which is barely enough for a GTX 770. Even worse, it has voltage drop under full load.
Even if the PSU is not the only bad part in your system I would replace it asap to prevent damaging other parts in the long run.

it sounds like a psu issue, perhaps you need a new one. if you have an old one laying around you could test it before you buy a new one. Unplug your old psu from everything inside the case. Then take your other psu, and plug it only into the motherboard and hard drive. Do not plug it into the extra stuff like your cd drive or if you have a graphics card that you can plug in. This is a precaution incase the all the extras pull more power from your psu than its willing to give. then plug the psu in and see if anything happens. Hopefully the computer will start and boot. Test it several times in a row before concluding you need a psu.
I did this with an old acer i found outside someone had thrown away. I brought it home and the machine would turn on and work sometimes, and sometimes the fans would spin up but nothing else would happen. I tried starting the computer over and over an it actually booted 4 times out of 10 power ons. I finally diagnosed a bad psu, it was a 300 watt. I unplugged it from the computer and used an old 180 watt psu from an old ibm i had, plugged it into the board and the hard drive, the computer booted 10 out of 10 times. Solution found.
I then purchased a 300 watt psu from tiger direct to replace the original one.
If you want to make upgrades to this computer or just want to be safe you can definitely buy a more powerful psu like a 650 or 750 watt and install it. It wouldnt hurt anything.
If you do preform a test though, do it proportionally, if your computer came with a 550 watt i wouldnt try using a 180 watt psu on it.
Maybe just unplug the one you have from everything but the hdd and motherboard and see what happens then first, then proceed with testing a new psu.

From a performance standpoint, not much, honestly. Many of the seasonic gold operate near platinum efficiency anyway. Some may have a longer warranty. Before you are running a sli setup, they won't be running at peak efficiency anyway.
Either way, you can't go wrong.

That PSU is terrible, I wouldn't trust it to supply power to an LED lamp. They claim it's an 800 watt but it can't have it's combined output over 480 watts and only 432 on the 12v lines? It's trash.
