Direct Replacement for MSR3640 and MSR3660

This 300W switching power supply module is built specifically for the MSR3640 and MSR3660 platforms. It delivers a steady 12A output to match the original unit. The part is supplied new and has been tested working before shipment. It is intended for technicians or operators who need a like-for-like swap to restore power to those models.

Standard ATX Form Factor for Straightforward Swaps

The unit follows the ATX form factor so it fits the existing mounting points and connector layout without modification. Installation typically involves removing the old module and plugging in the replacement using the same cables. The main risk is ordering this unit for a different model; it is not compatible with other chassis or power specifications. Verify the exact model number on your current supply before purchase.
