I used a 4 pin to power an 8 pin socket (Help)

Relixi · Feb 19, 2017

So i built a new system about 2-3 weeks ago and i didn't have the money for a new psu and gpu so i just used my old ones my mobo had 8 pins for the cpu connector but my old psu only had 4 pins, i thought i could use it as a temporary until now. But Now I have the new Gpu and psu the system doesn't run as well as it should, could i have damaged my cpu or mobo?

Current system Specs
CPU - i5 6600k
GPU - Asus GTX 1060 Dual OC
Mobo - Gigabyte GA-Z170 Gaming K3
PSU - Corsair CX500M

Unless you tried overclocking you probably didn't do it any harm.

Did you perform a clean installation of the graphics driver?

Crumpet 1 :

yeah tried that do you know of anything else that could be causing an issue ?

There's always the potential that your new PSU isn't supplying the power correctly.

In what way is the system not running correctly?

just a little slow in general and cant get good fps in games at all

EDIT looks like you covered this [strike].What kind of not running as good as it should are you talking about. [/strike] I would be interested in knowing if your video card is getting to 90 percent or higher under heavy load. If it is chances are your card is giving all it can and simply not as fast as you hoped for.

Can you ensure that your clock speeds under load are correct?

You can use something like GPU-Z to ensure your video card is running at full PCI-e speed(ie X16 @ 3.0) when under load as well. In rare instances the video card will get stuck at a lower speed(lower link speeds are normal at idle, but should jump up under load).

Did you use DDU to uninstall your old gpu drivers before you Installed the new one.
Even if they are both Nvidia cards it's always better to do it this way .

you think i should get the software and try it?

kango69 :

also you think i should try using this to uninstall my current drivers and double check for old ones before reinstalling ?

kango69 · Feb 19, 2017

DDU will clean your system of nvidia drivers old and new, so it's the best method when installing a new GPU.
Also when installing the Nvidia drivers do a custom install and only pick the drivers you want to install, if you don't use Nvidia 3D or GeForce Experience ( which I personally never install ) then why install them

nukemaster :

i just downloaded this software and played a game of H1Z1, the clock speeds were fine so was the temperature and the load only got to 16%.... anything else you would recommend ?

kango69 :

tried this and still no better, any other ideas?

Download this software

It will test everything in your system and then you can compare it to systems similar to yours to see if anything is running slow

kango69 :

just did this, could my hard drive be slowing down my whole pc ? including fps

nukemaster · Feb 20, 2017

HDD does not effect FPS. It will only effect loading stuff.

When you say 16%, was that a cpu or GPU load?

How do other games run?
