Why is my power supply broken

Not sure. Make sure that the power wire from the computer case is plugged into the motherboard. Make sure the main power and cpu power are plugged in as well. Then switch the power supply to on and press the on button on your computer case. Good luck

I have only installed to 500 watts or more. Probably not enough power from PSU!

Sounds like a ground issue with your power supply. Try plugging your power directly into the wall socket and bypass the power strip if you're using one.

I doubt it is the power supply but again I can not be sure. I would think it could be a camera issue if this is what happening.

It may be a defective unit or if you added any devices (dvd drive, new video card. etc) you may need a more powerful power supply. Also make sure you are using a surge protector. I hope I am not insulting your intelligence.

Probably a deffect since mine works flawlessly. Maybe you should check the power supply is working with the proper amps.

I made sure all the connections were the same (marked them) as I took off the old power supply and mine started right up. Maybe you have something connected incorrectly to the motherboard that relays power from the start button, good luck.

I agree with the previous response. If you know the outlet is good and its fully plugged in and you push the on button and nothing happens most likely the power supply in the unit is bad. Time to return it.....

Make sure all the necessary power cables are plugged in, but most likely is a problem with your motherboard.

Have you tried a new power supply? Mine stopped working suddenly as well. Power supply did the trick.

It could potentially be that your motherboard has failed as well. Does it work plugged in?

How do you know it's not the mobo or pc power switch. It could be a bad cpu etc. If you suspect a bad power supply and don't trust the power supply tester, try to obtain another known good power supply and install it.

Make sure the input and output are correct. If it still doesn't work then it's the power source. Try a different outlet.

I'm not an expert on PC power requirements, but after 15 years of building and repairing PCs, I can say with certainty that the power supply can be the most finicky part of the computer. I'm not saying that it is what is causing your issues, but I've seen similar problems with power supplies in the past. It can also just be your power supply dying and it's only a coincidence that the symptoms decided to manifest after you switched to a new video card. My advice is to try to troubleshoot it as best you can. Perhaps underclock the new card to see if the problem disappears. Or if possible put back in your old card to see if the problem remains the same. If it does, it will definitely let you know something else is going on.

The power supply question has been answered numerous times.300 watts is OK. Check your cables unplug and reseat the video card. If you have a built in video card you may have to disable it from the bios. It is possible that you received a defective unit as well.

Try taking the battery out while plugged in and turned off. Turn it on without the battery installed. If it does not work the computer has a power supply problem most likely. I have replaced my power supply twice and my battery four times in 6 years.
