Yes, its an old ATX style power supply but still useful if you need to quickly "throw in" an ATX supply for your favourite "old timer" PC
We purchased this unit (new) as a spare "backup" in my previous business but it never got used, new old stock.
These power supplies were used a lot in HP PC systems of the time

History:
This ATX power supply was kept as a backup in case one of our HP workstation PSU "fell over" due to power issues.
This power supply was kept as a back up but never actually used.
I powered up the power supply, its been sitting in the workshop for a long time!
No issues on startup, fan runs and no fan noise (bearings are fine)
Shorted green to ground (actives the PSU)
I then checked ALL of the voltages at both the motherboard connector and the AUX connectors, all are within tolerances. Those expected tolerances were:
+12V supply measures 11.83V
−12V supply measures -11.54V
+3.3V supply measures 3.31V
+5V supply measures 5.09V standby
These voltages are all within expected tolerances
After testing, I sealed the complete power supply in plastic to protect from dust/dirt.
