Thanks this power supply works great for my Retevis RA87 40watt GMRS radio. No more power failures. The power supply is quiet and hasn't needed to run the fan yet.

Yes you are correct. My power supplies were both underpowered at around 5 amps 7 amp peak. Now I just need to find a cheap power supply.. I have been looking for 20 to 30 amps... what would be the ideal amperage?

Right out of the box it had a problem. Any time the PTT button is used on High power setting the radio reboots.
