Without specs on the electronics you are left with the option of measuring. What equipment are you running? I would think 300W would be plenty for the combo of a typical preamp plus turntable. Of course throwing a power amp on there may be pushing it if it is a powerful one.BTW 1Watt = 1Joule / 1Second and is the measure of energy taken from a given charge over time.

Thanks for the reply.
Currently I have an Adcom GFP-565 preamp and GFA-545 (100 wpc) power amp and a Music Hall TT. Would also like to plug in my Oppo CD/DVD player. Soon, I will be replacing my Adcom amps with the 55 wpc Rogue Audio Cronus integrated amp.
TT ~15W max
GFP565 ~10W max
GFP545 ~200W plus overhead 20W (?) is it peak or continuous (?)
Oppo DVD player 20W (?)
265W total if estimates for amp are reasonable. This says 300W will work, however more overhead is always better when speccing power conditioning. Also if my assumptions of amp power being peak draw could also mean too little overhead and cause compression/distortion during loud spots.
Pre and TT OK- not the power amp. When you get the Oppo and Rogue only the Oppo and turntable.

Volts X Amps = Watts A piece of gear will list its maximum consumption of AC power in watts, usually right next to where the AC line goes into the component -
There we go! Thanks for the information.
v x I = watt is true if it is true resistive load (power factor =1), most equipment these day will be rated in VA instead because of non linear load that will be seen by your AC power because the power supply in your machine may have switching power supply pr highly iductive or capacitive loads.
You're welcome. I love this place.....
