I don't. I only pass through the 5 VSB and ground from the MW directly to the mainboard. That is enough for the mainboard to pull down on PS_ON which I connect to the mw PS_ON through an inverter IC. In that regard the EPP-400 is already nearly a full fledged PC PSU except for not having the other power rails like 3.3 V and 5 V. It even has a PG (power good) output that could be connected to the PWR_OK pin on the mainboard as well (has to be inverted as well i think).Oh, and also the 5 VSB from the MW has 120mV p-p ripple which isn't in spec unfortunately :/
