gusto ko lang pong itanong kung paano po i-check ang isang power supply kung talagang 500watts ito. example po bumili ako ng power supply na 500 watts, gusto ko pong malaman kung talagang 500 watts po ba ang power nya. can i use some kinda tester para malaman ang true value ng wattage nya? thanks guys!

but you can always compute for the wattage.

Power (Watts) = Current squared x Resistance
Power (Watts) = Voltage x Current
Power (Watts) = Voltage squared / Resistance
