70 W ATX power supply for legacy systems

The KHACHIMO PSR70-A delivers 70 watts through a standard ATX form factor and is supplied new. It matches part numbers 6503, 6506 and 6506R and has been tested working. This unit suits older PCs or industrial equipment that require a low-output ATX supply.

Verify connector layout

Confirm that your motherboard uses the same ATX main-power pin-out expected by the PSR70-A. Check that the combined 70 W output covers every component in the build, because the unit cannot support modern CPUs or discrete graphics cards. Ensure the chassis has space for a standard ATX supply and that no proprietary connector is required.

Questions about this item

Does the PSR70-A include any cables or mounting screws, or do I need to buy them separately?

The PSR70-A is supplied as the power supply unit only; ATX power cables and mounting screws are not included and must be purchased separately.

Which of the listed part numbers — PSR70-A, LS8M4220, S6503, S6506 or S6506R — should I choose for my build?

All five codes refer to the same 70 W ATX switching power supply; choose the one that matches your existing unit’s label to ensure the correct replacement.
