AthenaAT40 400W AT POWER SUPPLY Athena Computer Power AP-AT40 400W AT power supply: Computers

So I say a few bad reviews for this. So before I tried it out, I hooked up a 10 amp load then measured the voltage. I got 5.025 for 5volt side and 11.89 volts for 12 volts. So after hooking it up to a real computer remeasured the voltage. Everything was good. I am pleased with it. Running AMD K6III+ at 600 mhz. worked for me.

Thank you for carrying this power supply. It was able to extend the life of an older computer that's used for doing property lines. It came complete with power cord and power switch.

I have had to resort to used salvage in recent times to repair older industrial computers. Now I can get new ones. They appear to be the same quality as the old ones to me. Working fine.

My original PS was 200W. This is 400W, and it has a better mix of power connections. It really is new, not NOS. I'm quite impressed. Also, it's completely quiet. I couldn't hear it on my bench, and I had to put my hand to the fan to check if it was on. I will buy again IF there is EVER a need to do so again.

We had a power supply die on an old AT style computer when we had a connection fail in cubes that should have been replaced 10 years ago. We needed the old computer to run a particular software package, so I bought this power supply and installed it. The computer is back up and running, and our special software package works great.

I’m really happy to see newly manufactured AT power supplies, with the hope of making retro systems easier and safer. At 400W, this provides plenty of power for vintage systems and has a good number of connectors. The power switch cable is a bit shorter than the power supply I replaced, and just barely fits in my mid-tower case. Overall on paper it looks great and I want to love it.However, I’ve gone through two of these power supplies and they are both providing too high of a voltage on both the 5V and 12V rails which will shorten the life of the system - and absolute no for retro system builds. With that in mind I cannot recommend this PSU and have editing my rating down accordingly.

This is being used on the floor of our manufacturing plant, so as far as I know it works great.

Poor execution for a power supply design that has been around since the near dawn of personal computers. This power supply is so light weight it feels like it’s empty. The power voltages on 12v and 5v are too high and out of spec. The power on cord with included switch is shorter than every other AT power supply I have ever owned. Over all this is a $12 power supply you would get direct from China, but for a $50 price tag. Disappointed more than anything, as it’s junk… why are companies building junk in 2022?
