I assume this means it uses PWM or something to give the 13.8v DC?
I assume also that this also means I can't use it with my AQX pumps?

I've found a Mean Well DC-DC Converter that was price quoted at $23.61 plus shipping. Its physical size is slightly less than 4-in square and is ~ 1.4-in in height. It's about 2X the size that I had planned for, but I do have plenty of room in my Lian Li PC75 case. The Mean Well model designation is SD-25A-12 and it is rated at 25.2W, 2.1A @ 12V. Input voltage range is 9.2V to 18Vdc. Adjustable output voltage range is 11V to 16Vdc, which is ideal for a single Swiftech MCP600. I would be operating the pump at 14.0V which should require ~ 15 to 15.5W.
