Voltage Regulator / PSU Wattage Ratio

[Guest]

Hey Guys, got a techie question for you which im having a hard time
finding answer. I have a 500 watt / 220 volt Voltage regulator which my
PC is directly connected to that uses a 700 watt psu.
My Question is, since my voltage regulator is supplying power to my PC,
does its 500 watt power output affects the current wattage of my
PC's 700 watt psu? Thus reducing the wattage of my PSU from 700 watts
to something less???

Any help or info regarding this will be highly appreciated. Thanks in advance.

Possibilities in your situation...

1) Your PC don't draw 500Watts. You have a 700Watts PC supply but thats the capacity of your PC PSU. Most likely your actual load is less than 500Watts.

2) Your regulator are cheap versions that actually connect you to the main supply and does nothing most of the time

Anwer to your questions:

1) No if the actual load is less than 500Watts.

If the the actual load is 500Watts or greater. What will happen depends on your regulator. The cheap ones will do nothing. The good ones will send out an alarm and trip the load due to overload condition.

2) Your 700 PC PSU capacity is not constraint by your 500Watt Regulator. Refer to answer 1) with respect to potential behavior of your regulator when the load is => 500Watts.

Thanks a lot for the response dude, it is really appreciated.

Regarding my 500 watt voltage regulator, though its a good built and quality
and made from japan, it can only control the voltage and not the wattage, coz its
fixed @ 500 watts. What happens if my system for example consumes 650 watts of
power? For sure my system will suffer due to the lack of wattage it receives from
my psu, coz my psu only receives power at a fixed 500 watt from my regulator?

Also, since my regulator is fixed @ 500 watts, will it explode or overheat
if my psu requires way more wattage that my regulator's limit? Because it
doesn't have any overloading protection in terms of wattage.
