Definitely the PSU. What I don't understand is why a power supply will just die sitting in a box.

No disassemble for now! As suggested earlier I just plugged in an extra power supply outside the case and confirmed it will boot and run. I'll have to disassemble to install a replacement psu if I can find one that fits the case.

It's ALIVE! Next steps: find a game to test the GD-ROM drive. I thought I had a couple somewhere but I may have to go to ebay. Then, search for a working power supply that will fit the case. Thanks to @Franco23444 @djsheep and @Darksoft for nudging me in the right direction with this.

Thanks for that advice. I don't have another power supply with a 20 pin connector but I can probably borrow one from a friend.

Thanks @MetalliC . That makes a big difference in whether I take the next steps to try to get this machine working.

The PSU is a Bestec model ATX250 which I believe is an ATX version 1 20 pin power supply. It is buried at the bottom of the case, very tight fit, and will require full disassembly to remove. I think I might be able to find a unit with the dimensions to replace it. I wasn't sure what those 2 leds...

Here's what I did and observed: Unplugged power cord and opened up the box; removed the drive to access the main board. The capacitors appear pristine, no swelling that I can see. To test the power supply I disconnected the 20 pin power connector from the main board; put a jumper (paper clip)...

Ok, I'll open it up and take a look. It looks like some disassembly is required to get a good visual inspection of the main board. I'll post back after I have done that. Thanks @Franco23444 and @djsheep for your responses.

I have a devkit HKT-0120 that has been stored in it's box for over 10 years. I believe it powered on and worked when I last tried it but now I don't get anything when I plug it in and push the power button. No lights, nothing. Any ideas what the issue might be? If the CMOS battery is dead will...
