PSU Swapout = Increased power usage

Obie1kenobi

So this morning I swapped out a 550W Antec true power supply I do believe, I'm not sure of it's rating or whether it has one.

I have my 4690k at 4.0-.4.2 Ghz, 2 monitors on and was using roughly 130-140w on Average Idle

With the Cooler Master V650 I replaced it with, everything plugged in the same, nothing added or taken away (yet), and the power usage is around 150-160 with just 1 monitor, and 180w with 2.. is this psu faulty or... Am I doing something wrong ?

Sorry I didn't realize I posted on that account, don't know why it logged into that one, Haven't used it since this was made anyway.

The v650 is gold rated, and the antec True Power 550 does not say

This is a Older TP 550, it has a green and black logo unlike the current black and gold one.

However, I started playing battlefield 4, I don't remember seeing the max wattage used but idle in game was around 220 (this is with v650) and After I left game usage went down to 135-145 so more in line with the Antec, but when i turned the monitors off it went down to 88w, instead of the 97 it was at before.

Unless you are reading through the outlet ignore the estimates by software. Mine reports I am using 0.1W.

For an apples to apples comparison, you should measure the power used by just the tower. Connect everything else to a different power outlet.

But why would monitors pull more power after a PSU swap is still a mystery.

All of the above considering you're not relying on software readouts.

I am taking this directly from the Outlet, not using software

The PSU is powering the system only, not your monitors too.

You are introducing variables into the equation.

Measure the power of your PC only -- not including your speakers, monitors. They draw external power.

Im talking about number taking with monitors both turned on and off, and observed during those time periods.

The reason I do it like this is so I can get the total picture on how much I am using. I could simply buy other Wall outlet things, but y'know

A larger than needed psu will likely be less efficient due to efficiency only being guaranteed at certain loads. Efficiency tends to suffer at lower loads.

I'm pretty sure I figured out the problem,

Now I can't be sure on this because I didn't check this specific thing before swapping out PSU's.

On my z97 Ranger motherboard, in the BIOS the EPU Power Saving thing was switched off, I switched it back on and all is good now!

Why would you enable EPU if you have your CPU overclocked?
