Question How do I check that my PSU is providing enough power to my whole system ?

I recently upgraded my CPU from a Ryzen 7 3700X to a Ryzen 9 5900XT.

Ive started to noticed a few things happening to my PC that used to work fine before the upgrade.
Main one that got me curious was my USB extension cable(1.5m or 2m) the runs from my PC to my desk that I use to plug my controller in when playing certain games (I noticed because I was getting ready for Monster Hunter Wilds Beta)

So the issue I noticed was my controller would get power, powers on, connects and works for like 10 seconds then will disconnect, 10 seconds later it will reconnect then loop. (Controller is at full charge as I plugged it into the wall overnight before using it)

Another issue (I posted earlier in the week) was one of my SSD just stopped working - after I turned off my PC for the night I booted it in the morning got BSOD then after my PC reset everything was working normally. Till today when i got home where my taskbar refused to load and cause a Windows Explorer error, once again a reset just fix it)

I know my PSU is 6 - 8 years old, I dont know if that is a problem - I do use a electronic airduster every 3-4 months on the inside of my PC to dedust it - I did dedust my PC when I was replacing my CPU.

So is there a program I can install that can auto detect how much power I am drawing?

my pc specs are;

Motherboard: Gigabyte X570S Gaming X
CPU: AMD Ryzen 9 5900XT
CPU cooler: AIO 240mm - cooler master NO LED
GPU: NVIDIA 3080 TI (Gigabyte or MSI)
RAM: 32GB DDR4
Storage:
C: Sammsung SSD 970 EVO 500GB
D: Sammsung SSD 980 PRO 1TB
E: Sammsung SSD 870 QVO 1TB
PSU: Corsair 850w (I think)
Chassis: Ti (I dont know the model, it's the one with two 280mm fan on the front)
OS: Windows 10
Monitor: Samsung Odyssey G7 32" (x2)

As I understand your post the PSU is a likely suspect.

Likely at or nearing its' designed in EOL (End of Life).

You can use a Kill-a-Watt meter to observe how much power your system is using.

Kill A Watt meter

If you have a multimeter and know how to use it (or know someone who does) the PSU can be tested.

Not a full test because the PSU is not underload. However, any voltages out of tolerance indicate that the PSU is at fault.
