New Power Supply?

[Islaymoocows]

Hello, and recently I have been having a problem where my monitors go black and there is a loud buzzing noise. This only happens when I am ingame of almost any game (including minecraft), I think this is because of my Super Old Corsair TX 650 watt power supply (I think its around 5 years old). I'm using two Cooler Master Sickleflow Green LED fans, 2 Cold Cathodes, 2 HDDs, and an ATI RADEON 5770 and I think it is just too much for the old thing. Also, I installed the Cold Cathodes just a couple days ago and it has been having the problem since... Any Ideas? Should I just get a new power supply or is there any way to fix it?

PC Specs: AMD Phenom II 955 Processor 3.20 GHz
6 GB of RAM
Some really old motherboard
2 1TB HDDs
ATI RADEON 5770
And of course the Corsair TX 650 PSU

Thanks! Any help is appreciated

That PSU should handle those specs , no problem.

As long as the PSU is running normally it has plenty of power (even with 5 years of use). I'd take off the cold cathodes and see if the noise stops, and it stops blacking out. If you can get ahold of another PSU to test with, swap it out and see what happens, it might just be dying 🙁
