Astron 70 amp regulated power supply is what I use. They are big and heavy well known and used in the Amateur community.

I use it for my HF station and it easily powers my Kenwood TS590 and 400 watt amplifier and auto-tuners and other low amperage accessories.

A 35 amp is all you need for a 100 watt HF radio with a little amperage to spare.

The most important thing to look at is the power supply's continuous rating rather than the peak.

Astron's 20 amp power supply for example peaks at 20 but the continuous rating is 16 amps. That's a little shy to run a 100 watt HF rig. My 70 amp peaks at 70, but the continuous is only 57 amps.

Seems like you get cheated but that's the way power supplies are spec'd and sold.
