I like to match my voltage when I stack them, I would think there might be issues if you dont. MegaWatts are nice units.

Big switching power supplies - what's the forum favorite?
- Thread starter N8YX
- Start date
I've an Astron RM-50M under my desk. It does the job year after year. No RF hash and no fan noise. I detest fan noise, especially if it is continuous. Some switchers are temperature activated while others run the fans continuously. Those that have a tiny fan may sound like they're ready for takeoff!
I've a Samlex installed in a TKR-750 repeater that I'm testing here. Its fan is temperature controlled and the power supply appears to generate very low RF noise, at least I don't notice it. This is another important consideration, especially on the lower HF and MF bands.
You might see if you can get a 100% refund guarantee if you're not completely satisfied with whatever you choose.

12V, 76A Delta surplus server supply I modded to 13V and slapped some binding posts on. Tiny little thing for the wattage, but sounds like a vacuum cleaner running under the bench
