The DSX12VD will be perfect. I just bought one for my Commell LS-372 which has the 4-pin P4 style power connector like yours. I used to have the M2 but the DSX12VD is much better suited. If you use the M2 you will have to jury-rig a relay in somehow that triggers the M2 to simulate shutdown. The problem is that these boards don't have the 20-pin ATX connector to tell the power supply when they are done shutting down.
