One Month 24/7 PSU / Energy question? - Page 2

post #11 of 14
The efficiency is important for power consumption. Let's assume the pc is pulling 600W with the PSU at 85% efficiency. Total power consumption: 600/85 *100 = 706 total power consumption. The other 15% is converted in to heat, that's why PSU's need good cooling.

Thanks for the help understanding things.

Simply because a power supply is capable of supplying 600W does not mean it is always ouputing 600W,it depends on the load placed upon the power supply.That 600w power supply may only be putting out 200W,which is way less costly that if the power supply was operating where it was most efficient.

In short,load is more important than efficiency when it comes to figuring out cost of operation. What do you think cost more to run, a machine with a 1200W power supply that has a load on it that causes it to put out 600w or a machine with a 600W power supply that has a load on it that causes it to put out 200W?

My point is that it is still putting out 600W.It could be putting out 600W effiecently or unefficiently,doesnt matter.What matters is that it is putting out 600W and that is going to cost a lot both the efficient way or the non-efficient way.Simply because a power supply is efficient doesn't mean your getting free output,just a bit less expensive.
