PCU upgrade

[gertje_sel]

Hello

 

In my system i have:  MSI Z270-A pro, I7-7700k, rtx 2070, 2*8gb 3200 MHz/16, NZXT kraken 52X waterkooling, 2 stock fans off 240mm, gaming mouse, gaming keyboard and a 750w bronze coolermaster PCU.

If i try to overclock either/both the GPU or/and the CPU im missing frames in-game (Rainbow six Siege) or same other stuff is happening

GPU overclock: mem clock 7200 GPU clock 2100. CPU clock speed 4600

I have looked at some PCU calculators: https://outervision.com, Cooler Master and some more.

But they all say something different where the lowest PCU was 500w and the highest 1300w

 

Do i need a upgrade for the PCU or not

You mean psu(power supply unit) right?

It depends. If you have a really crappy coolermaster 750w then you would need to upgrade, otherwise no, as those components draw max 500w.

 

So what is the model of your psu?

Probably a really crappy coolermaster!!! Cooler Master G750M. Bought it on 2-27-2018

Power supply calculators over estimate like crazy. I put my rig in my signature and you can see a clear disconnect.

Then your overclock probably isn't stable. Try stress testing when you're overclocking to make sure it's stable.

 

PSU wattage isn't an issue.
