When I first got my MiSTER Pi I got the Raspberry Pi 5 PSU to go with it:

Apparently the Pi5's power is slightly not standard and needs 5Amps at 5Volts which from what I understand most USB power supplies cannot do and I think is not even part of the spec. The RPi5 PSU was listed as 5V5A so I assumed it either did not have PD or only used it if the device asked for more than 5 volts.
However once I got a USB tester I checked the PSU and noticed that it was sending 12 volts to my MiSTer at about 0.6A.
The MiSTER Pi's setup page recommends using a PSU that does not use PD if possible to reduce heat from the voltage conversion, and I saw many recommend a 5V4A PSU that also has a power switch from iUniker:

So I got this, and tested it to confirm it was sending 5 volts at about 1.6-1.7 Amps. But now started having problems with it.
First is when I switch on my MT-32 Pi my MiSTer reboots. It works fine after rebooting, but it didn't do this before with the Pi5 PSU and I worry if that can be bad for it.
But another problem is that the N64 core has become glitchy on boot. Most of the time now when the core starts the screen is half-red and half-black (Sometimes it's all-black as if it's normal normal but the issue is still present). When it's like this no video is displayed. If I launch a game I can hear it running in the background but the video stays that half-red (or all-black) image. Resetting does not work. The only thing that seems to clear it up is either rebooting the MiSTer and hoping it does not happen this time, or toggling Clean HDMI on/off which seems to reset the video. This never happened with the Pi5 PSU, but happens almost every time with the iUniker PSU despite that one being the recommended one to use.
Any advice on this? Have others experienced? Or experienced it with other PSUs or even on boards other than Taki's?
