Got the Mean Well LRS-350-24. Printed a PETG cover on the other 3D printer for the terminals and holder for the fuse switch. Bypassed the Heated Bed MOSFET. Wired everything back up. 
 Recompiled Marlin with a bedtemp of 120 (realizing maybe it should be 110 maybe? When they say the bed can go to 110, is that with a 10-degree buffer? Or really should it be 100 max?)... anyway, i can get to 80-degrees for the bed now for PETG. Takes a long time. First attempt at PETG and I realize I messed up my Z-adjustment. Will play with it tomorrow and readjust. And by the time it gets there, zoom in and take a look at the corners of that flex plate. Heh. Yeah, don’t think they will do 80C bed temps. The magnets aren’t enough to fight the thermal changes. Maybe you need glass for that hot. You can just see my metal Z coupling. 
 I don’t trust this printer with just Octopi watching and mic/speak to hear alarms... I did get a bed temp runaway at about 103C when trying to get to 110. No idea what that was about, but beep is loud and doesn’t stop. :) Oh well. 2am. Waaaaay last bedtime.
