The EVGA 600-B can cause instability in the Apu frequency.
Yesterday I upgraded my 300 watts Be Quiet! Psu to an EVGA 600-B for the EVGA 600-B one, but since then I've encountered some strange issues. Initially, when I turned on my PC, it would restart on its own. I resolved this by adjusting the CPU voltage, but the real problem emerged later. My APU's clock speed isn't steady—it fluctuates between 4.5Ghz and as low as 1.8Ghz, sometimes dropping to 4.0Ghz or even lower. During stress tests with Prime95, the frequency would drop, and some cores would display a "hardware error" randomly. Could this be related to the PSU? My system uses an AMD A8-6600K, Artic Freezer XTreme Rev 2, ASUS A88MX-A, 12GB DDR3 1600, one SSD, one HDD, and three fans.
Could you retrieve your previous PSU and check if the issue continues? If the old PSU doesn’t show the same problem, it’s likely the 600B unit is defective, as power shortages often point to hardware failure during testing. Also, make sure your motherboard BIOS is current.
Can you retrieve your previous PSU and check if the problem persists? If the older PSU doesn’t show the same issue, it’s likely the 600B unit is defective, as power loss could indicate a hardware fault during testing. Also, confirm that your motherboard BIOS is current. My BIOS is up to date; when I used the old PSU it ran the 2014 version without issues, but now I’m reattaching it and will keep you informed.

Would you like me to bring back your previous PSU to check if the problem persists? If the older unit didn’t show the same issue, it’s likely the 600B model is defective, especially since power loss can indicate a hardware fault during testing. Also, have you verified that your motherboard BIOS is current? I’ve confirmed my BIOS is up to date, and when I used the old PSU it ran smoothly with the 2014 version—no issues at all. I’m planning to reinstall it and will keep you informed.
Edit: Using the previous 300-watt PSU made the frequency drop to 4330 once, but now it’s stable at 4500. Since it worked fine then, the new PSU seems faulty. To be honest, it was a subpar choice overall.

Note: With the previous 300W PSU, the frequency dropped to 4330 once, but it stabilized at 4500 now. Since it worked with the old one, the new PSU seems faulty. Honestly, it was a poor decision. Even with the old unit, there’s a chance it might fail tomorrow—so I’ll run more tests.
Which PSU should I purchase? Everyone I consulted seems to have issues. I’m planning to spend around 200 euros (in Italy) by the end of school and have two options:
- Install an 1060 mini in this system if I resolve the problems;
- Buy an AMD FX-8320 and an MSI Mod SoAM3+ 970 Gaming 7693-040R, get a used cheap GPU until my birthday in August, then upgrade to a better one.
