The past day or so I've been getting a burnt plastic smell coming from the area where my computer is when my computer is powered on.
I pulled the computer out of its position and inspected all of the connectors in it, only to find nothing. I read online that 9 times out of 10 it's the PSU, so I went ahead and ordered another one. The PSU does have a (slight) odor coming from it when I put my nose up to it.

The interesting part is: it still emits an odor even when the computer is switched off. I had my computer switched off (from the psu side) all night and still got a burning smell. Why would the PSU burn when the computer is turned off?

I woke up this morning to the burning smell in my room. I went behind the computer and pulled the cable out of the PSU (the computer wasnt running prior) and the burning smell almost instantly went away.

Another thing to note, is that my computer wouldn't shut down these past few days without me actually hitting the switch on the PSU. After shutting it down, a device would instantly turn it back on again.

Could it be my PSU, or is there anything else I should test?

Intel i7 4770k
16GB DDR3 Corsair Vengeance
EVGA GTX 970
Corsair 750M PSU
Gigabyte Z87-DS3H Mother board
Corsair Scimitar Mouse
Corsair K95 RGB Keyboars
WD 1TB HDD + Samsung 250GB SSD

Thanks for the answers in advance. I appreciate it!

If you believe that it is your PSU contact corsair. They are normally very helpful and loyal towards customers. They may even send you a new one.

It's also important that you don't use this supply at all. There is a risk of fire especially if you don't have GFCI installed.

Well if you've bought another PSU your problem is solved, make sure you're PC is clear of dust and debris which can impede airflow making the system get hot (and start fires). Ensure everything is connected properly and the intake/exhaust vents on your PC aren't being blocked (touching a wall or there's an object in front of it for example).
