Small problem with PSU

[Captain Master]

Hello!
I bought this gaming PC 1.5 years ago, and I recently had to buy a new HDD for it.
It's everything OK, unless the fact that it runs games at 40-50 FPS instead of 60. I tested my processor, and it showed some really bad results, so I bought a new AMD Fx 6300.
Now my PC runs games at 25-35 FPS.
Before we go into details, here are my PC specs:

CPU: AMD Fx 4300 3.8 Ghz (old)
AMD Fx 6300 (currently installed)
GPU: Nvidia GeForce GTX 750Ti
RAM: 12 GB
HDD: 1 TB
Power Supply: 500W (keep this in mind)

So, I went to the shop where I bought my new CPU, and they tested my computer with a GeForce GTX 1050. Results? 9-10 FPS! Then I started being suspicious about the Power Supply. I think 500W is not enough to power up my whole system, since most parts use a lot of energy.
I just need someone to make me sure about that.

Thanks in advance!

Try this: https://us.msi.com/power-supply-calculator

NewEgg has one too. https://images10.newegg.com/BizIntell/tool/psucalc/index.html?name=Power-Supply-Wattage-Calculator

Might be thermal throttling if the thermal paste was not applied properly - see YouTube for instruction videos.

Thanks, now I see my problem isn't in the power supply. Results said I needed a 450W power supply.

A decline in FPS (the 1050 should have been slightly better) makes me wonder:
- thermal issue
- malware (BitDefender rescue disc might be a good idea)
- a bios setting (download manual for mobo)
- old drivers (chipset & audio on the mobo.... or even left over display driver from prior versions - use DDU, free utility available on this website)
- bad or corrupted anti-virus/anti-malware (download new, uninstall old and reinstall with new)

First step should be to inspect Task Manager in 'detailed' view to see what is using resources.

Thanks for your help, my Computer went out for a week for some repairs, turns out there was a problem in the Motherboard and in the RAM Memory. It's all ok now!
