Absolutely NO. Check your equipment's power consumption specifications. The PS500 was not really designed for power amps.
Both ZD and Elizabeth are correct. I use a P500 with great results. But...

The P500 has two completely different banks of outlets. One bank of four outlets supplies regenerated AC. I use these for my phono pre, CD player and turntable controller. The P500 works great this way, with improvements across the board. But, in spite of what the literature says, they are current limited and would not be good for power amps. As Elizabeth says it would run way too hot, and would adversely affect the sound. Even my large power supply line preamp has trouble when plugged into the "regenerated power" outlets, sounding dark and congested as a result.

But, the unit also has two non-regenerated power outlets that are simply one of PS's "Ultimate Outets". These are not current limiting and use simple non-regenerated filtering which would be fine for power amps. I find the sonic effects of these to be subtle to say the least. But, overall, the unit can work well for efficient power distribution for power amp and front end component filtering.

If you are buying the unit used, be careful that it was not previously used with power amps in the regenerated power outlets. My unit had been used that way and as a result the resulting excessive heat had dried out the caps. They had to be replaced. I recommend you replace the power cord with something of higher quality; especially if you will use a power amp with it (in the non-regenerated outlets).
If you decide to buy the PS500, replace the PS Audio fan with a much quieter fan. I used a Noctura fan (50% db quieter than the original)
I use a PS Audio P600 with a JRDG Model 112 power amp plugged into it. In four different houses the system sounded better with the power amp running through the P600. I've used this combo for 10 years powered up 24/7. It has withstood multiple power outages and a near miss lightning strike that took out other components in secondary systems. Never, ever had a problem with this setup.

WTF, the P600 just leaked caesium onto the carpet! It looks like a tough stain to get out.
