A linear PSU wouldn't be "better"? Something like a Korad? I recently got a WuZhi5005 knockoff and happy with it, but it's to feed motors. My Korad KA3005P has *much* less noise. And IIRC, would be cheaper than a complete 6024 kit -frontend+case+PSU. Not so much ooomph as the RuiDeng though
I hope you'll get better health soon.
