My computer's power worked fine until I moved it and I might have bumped it. Now, when I have the power plugged in and turned on and press the power button, the fans and lights turn in for half of a second then turn off. However, when I have the power supply switched off and press the power button, the computer turns on for a larger amount of time than when it was supposed to have power. What is going on????

If the switch on the psu is off and it still tries to power on at all I'd say the psu is bad.

Is there anything I can do at all to try and fix it?

Not really :(  Sounds like it was a low quality unit to begin with, I hope it didn't take anything out with it.

Maybe it's not enough watts. It's 800 W Apevia and it powers my amd A10 6800k 4.1ghz and my sapphire radeon hd 7970. Could this be the problem or is it definitely faulty?

For a system using a single Radeon HD 7970 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 38 Amps or greater and have at least one 6-pin and one 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C is the most important factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The problem is with the quality of your power supply unit.

The following two PSUs would be way better than any Apevia PSU:

I would check all my connections first. It could be a loose connection and the psu working properly.

that being said I agree Apevia is a pice of junk

So could you recommend a good psu? This is my first time building a computer so I am still a touch confused about some of this

Recheck my post above. I was editing the post while you were replying to it.

A single 7970 system needs a good 500W supply. I would get the XFX 550W that ko888 linked. Good supply made by seasonic and has the 1 8pin and 1 6pin you need for the card.
