New GPU crashing my computer

[Chippyz]

Okay, I will try underclocking the GPU first, if that doesn't help I will uninstall these drivers(from amd's website obviously) and try the drivers on the CD that came with the GPU, if that doesn't help either I will try to update the BIOS(even tho I'm scared that I will brick it) and if that doesn't help i will take the GPU and try it in another computer. Thanks

UPDATE:
So I underclocked the GPU a bit(like 10%) but it didn't work so I installed the drivers on the CD but that didn't work and now I decided to drop the power limit to -50% and the speed was about 1150-1250 MHZ and I played a whole game without crashing, I guess a new PSU will fix my issues, especially becuse this GPU requires a 6 and a 8 pin but this PSU has only one PCIE 6 cable and from that cabe, another PCIE 6pin is comming out, and only one PCI-E 2 pin cable and same thing another one comming out. Something like this:

And that's why I think it's not giving enough power to the GPU. I guess a new PSU will fix the problem right?

Yup def psu cant handle it

I think this and a few others turning up are due to intermittent power spikes of the total system or gpu exceeding the power rails capacity, always seams to be 650watt or lower non new PSUs.
It's starting to look less than coincidental to me.

So should I buy a 750watts psu?

I tend to go for single 12v rail models now, that's what I would advise, since no 12 power feed is then quite as current limited , I would if I were you ,so yes.

Dear Chippyz, Your PSU supports 2x6 pin pcie gpus or 1x8 pin gpu (6+2 separate pins together)....Your new gpu requires one 8 pin + one 6 pin pcie connectors... so your current psu is not enough..

Eidairaman1 can help you with some suggestions...he recently helped me with a similar problem involving a rx 570 + fx 8350 setup..

Yeah, I will get a new PSU, I will report the results. But it might take a few days for the PSU to arrive.
EDIT:
I might get this one, Seasonic Focus Plus Platinum SSR-750PX

Seasonic Focus Plus Platinum SSR-750PX ..Nice One...

Update:
I tried underclocking the gpu again and it crashed, so it might not be the PSU. I really don't know what to do at this point.

A good psu of 500w or greater with a single 50amp+ 12v rail will handle anything tradition with single gpu

I'm not sure of it's the PSU now, I will get a new one anyways.
I will try my old GPU to check if it's a software related issue.

 

[Gorstak]

uhm is your gpu bought new or used?

btw this is what a 6 pin looks like. The left one on your picture looks like a sata molex
You probably need one that looks almost identical to this one to power your mobo, alongside the main 10pin power supply, usually found to the left of cpu.

Psus will cause even a slower gpu to become unsteady. Make sure you are using the latest beta or 3 versions older driver...

I just tried my old GPU and it works with no problems and I haven't even reinstalled the driver. And my old gpu requires 2x 6pin

Update:
I Installed my new GPU back I run a benchmark and it worked until I clicked quit and then the screen went black and after 15seconds the computer just restarted.
And yeah I ordered a new PSU, should be here before friday.

So I got the PSU and I'm still having problems :/

I will try reinstalling windows.
