[P3 rubber washers??? Psu??]

welcome to the forum, 

 

the pillar is use to support the PCI-E bracket on top of PSU, and the rubber is use in between the PSU bracket and the PSU from preventing the screw of the pillar damaging the PSU. below is an image for you to refer to, if you find it too small to see it clearly, please visit our office product website for much clear image.

[P3 rubber washers??? Psu??]

I'm working on a p3 for the first time, and when installing the PSU I came ascross a little baggie that has the riser support and I understand that that is to be installed on the right PSU brace, got it.

 

But what are these 4 little 3m rubber grommets/washers for?
