Externally Powered USB vs New PSU?

[NormanD]

Hey there, I couldn't find this anywhere on the forums (likely due to its ridiculousness hah). I was hoping to get some advice or opinions on a decision im on the fence about. So when I built my rig few years back, my 450watt PSU was plenty. I've sense over the years as one would expect, upgraded my GPU and added more HDDS/SSD's, as well as plenty of extra USB peripherals. 

Which leads me to my current state of affairs, my PC has no problem with regular gaming or everyday usage. However I do find that if I turn on my desk fan, i'll get the chime from my machine as if something has been disconnected (no pop ups on screen tho of anything actually being disconnected). So I take that as a sign that the power supply in my PC is struggling or freaking out; something. 

 

So to remedy this I would obviously just upgrade my PSU, but then I thought about those externally powered USB 3.0 hubs. Would offloading the power draw of the all my USB peripherals from my PSU, onto an externally powered USB hub; be sufficient enough to ease the load on my PC? Granted a proper quality externally powered USB hub is in the ball park price range of a decent new PSU already.. but im just to lazy and dont have the free time to gut my PC and reconnect/cable manage the new PSU if I dont have to lol.

Any thoughts if this would work, perhaps someone has done this before? Thanks all!

what's your current PSU and how old is it? might need replacing anyway

Oh jeeze, I don't remember the brand. It was just an off the shelf at Staples. I built the PC around new years of 2016, so it just hit 4 years old.

What is that desk fan plugged into?

The wall outlet plug, just above the plug with the powerstrip that the PC is using. Which I suspect has something to do with the initial sound from the computer when I turn the fan on.
