PSU overclock reliability

post #1 of 7
Thread Starter 
Question is can your PSU cause excesive vDrop or vDroop? I know some of it depends on the mobo. But does your PSU affect how much vdroop or vdrop there is?

PSU does not affect Vdroop in any meaningful way, that is entirely determined by your motherboard's VRMs.

The PSU can affect the VRMs though; but the affects are too transient to appear on software voltage monitoring, or anything short of an oscilloscope. It can affect CPU stability however.

You were in on my last post about hunting a PSU. It seems as though you said the one I currently have is on the cheaper side, so would that have an effect on my vdroop. Currently bios is set to 1.275 and under load cpuz shows 1.224v vcore. Would this much of a drop be caused by my PSU?

I just ordered that Antec PSU and i'm kinda trying to determine if my voltages may be more stable with the better PSU.

When in the world did I say anything like that?

I just told you no, it's all your motherboard. A poor PSU can cause overclock instability that can force you to raise VCore, but it does not generally affect the gross voltage supplied to the CPU.

You were one of the main posters, just assumed it was you.
Someone said my Rosewill wasn't very good to begin with.
Didn't know if a crappy PSU would cause something like that.

I said it was a mediocre PSU, I never said anything at all about Vdroop.

I never claimed that you said anything about vDroop. It was something that came up in another thread and I was told to seek help here.
