I have a rather old computer rig and the fan on my trusty old Zotac GeForce 8800GT broke down. I hacked a 120mm fan onto the GPU heatsink and it is actually cooling enough, but I know that it is not future proof.
My friend had a Sapphire Radeon HD 7950 laying around unused, which I have bought from him. But when I install the 7950 with dual 6-pin PCI-e extra power, as soon as I turn on the power the PSU emits a high pitch noise. The computer POST's and I can go to the BIOS menu and even boot to Windows 10, but the noise is headache-inducing and I'm pretty sure the PSU is not liking it very much.
I'm pretty sure the PSU is good enough powered, but hey why don't I ask the trusty people at SuperUser. I don't have an extra +500W PSU laying around to test with, which would be the correct way, and as the whole rig is so old, I don't think I'm gonna buy a new PSU for it. I guess I just want your expertise on how bad the noise problem is for the PSU and if there is any setting or anything that I can do to remove the noise problem and make sure everything is stable.
Update 1 It's pretty unstable and sometimes just turns off. When it does this, I cannot start it from the power button. I have to turn off the power supply, wait some seconds and then turn it on again. Something's not right ... If I try to change BIOS settings and then save, it immediately turns off!
Update 2 Okay... Put in the old GeForce again, and it's also being killed. This time round Windows boot time. FFS, I need a new PSU! Any suggestions on what would be good for this old machine, but with regards to if I'm going to build a new rig, I could use the same PSU?
