Hi Experts ,

Please suggest me a 400 Watts PSU which consumes very low electricity from the wall and drives 18-20 Hours of CPU under full load. I want the budget as low as possible.


Thanks
Muthu.

VS Series PSUs: the entry-level 240V power supplies with high-end features.
The Corsair VS Series are a great choice if you’re building a home or office system with lower power demands, but you still demand the compatibility and reliability that Corsair is known for.

They are not made to be under constant full load.

Ok Now If I have this PSU in my system and runs the system under full load ( I do 3d renderings). Then how much power will it draw from the wall or how much electricity will be used in terms of watts/kilowatts for 1 hour.
 
Your system should be drawing less than 150 Watts from the power supply unit.

The power consumption at the AC wall outlet will depend on the efficiency of the power supply unit.

If the power supply unit is 84% efficient at 150 Watt power draw then you should be able to measure around 179 Watts or less at the power supply's AC receptacle.
