Replacement power supply for a PowerSpec B639 computer

Trying to find the correct replacement power supply for our PowerSpec B639 desktop computer.  The existing power supply measures 5.5 x 5.875 x 3.875 rated at 250 watts.  Unit is marked "250 Watt HEC-250CN-2RU".  Any suggestions?  Space inside the case is limited.  There is about 2 inches clear behind the existing power supply.

The original power supply in the B639 is a standard ATX form factor, so any ATX power supply should work fine.

Greetings! While we don't sell an exact replacement for that power supply, this power supply made by PowerSpec would be a very close replacement for it: https://www.microcenter.com/product/485310/powerspec-430-watt-80-plus-atx-non-modular-power-supply

The change in wattage would not effect your current PC, and the cables on this supply match up nearly identical to the supply in your PC currently, and the size is almost exactly the same as well so this should be good replacement for it.
