My Tagan TG900-U96 Turbojet 900-watt PSU recently burned out. I returned it, but it was no longer being supported through the third-party vendor I got it from. The vendor sent me an Apevia Warlock 900-watt PSU to replace my Tagan. I swapped it out, but now when I turn on the computer it won’t boot all the way. I get power lights, and the keyboard and mouse light up, but the monitor never kicks on, nor do the other connected peripherals (external Zip drive, printer, and scanner). What could be going wrong with my computer? I never had this happen with the Tagan. Could something have been corrupted when the original PSU died?
First, you should have contacted Tagan. The company offers a three-year warranty on its PSUs. There is certainly a chance that the components were damaged when the first PSU blew up—especially if it blew up due to, say, a lightning strike. But before you go any further with your new power supply, go back into the case and make sure everything is firmly inserted—you’ll want to make sure there are absolutely no loose connections.
You’ll also want to make sure nothing is shorting out in the case. The Doctor will assume that you are using motherboard standoffs in all the appropriate places—simply screwing your motherboard to the case itself would be one cause of a short. If you’ve done these steps and you’re still having boot problems, try using another PSU from a friend to see if your new power supply is at fault. The Doctor has seen many startup issues caused by the power-good signal timing that some boards require. Finally, don’t rule out the possibility that your new power supply is bunk. It does happen.
