When looking for a power supply for my Alinco dr-590, what type of
power supply would I look for? The radio says 13.8 v dc but if I get a
12 volt power supply will it put out the same wattage at the radio?

Astron RS-20A, or a RS-20M if you want meters. That'll handle your 45
watt radio. It's a 12 volt power supply that is internally adjustable up
to and above 13.8 volts. Get the RS-35 if you plan on adding an HF rig to
your station. Astron is standard equipment on many radio desks.

I agree with Jim about Astron. Been using 'em for decades. Simple, robust
design. Zero failures.
The voltage conundrum I believe derives from the necessary voltage to charge
a 12 volt battery.
Gotta overcome that old internal resistance; Turns out to be about 13.8
volts.
I don't know of a "12V" ham rig that would care about the difference.
Get outside the manufacturer's specified range (RTFB) and you may not have a
warranty.
