I like the Mega Watt power supplies. Quiet fan and you can parallel them quite easily. DNJ Radio has them at a great price. I bought one and will buy another pretty soon. They are voltage sense regulated versus current sense. That eliminates the need for a minimum load current so you don't hit the crowbar circuit.(Over voltage protection) I bought the 400 watt and put my most demanding load on it to test it and it worked wonderfully.(CNC XYZ axis control) Regulation is spot on with no drift.
