White Paste in PSU

[jippiee]

I've got a Corsair CX450M Power supply. I recently upgraded my GPU to a Sapphire RX590. The rest of my System is: Ryzen 5 1500X, 8GB RAM, B350 MoBo, 480Gb SSD.

 

Now I just realized, that inside the power supply at back side where the wall outlet is, there are two blocks from which there seems to be some sort of white paste expanding. One block also seems to have been displaced by a few Centimeters. (check the attached image)

 

Unfortunately I do not remember If my model always looked like this.

 

After a quick image search for the CX450M, I can find images of both with and without this expanding paste in the back.

 

What is the purpose of this paste? Is it safe to keep using this power supply?

It's normal. It's silicon caulk intentionally put in the PSU to keep components in place and stop them from vibrating. It's safe to use the PSU.
