Simply wrapped in clear plastic and tape (which bothered me) but works great so far. It has been running on my workstation for a month without any problems.

Received this to replace the original unit. I wasn't even sure if this was the problem but decided to give it a try after doing some research and realizing that the power supply is a common problem with the Dell Optiplex SFF. One day it just wouldn't start, but now it's working again. Hooray!

Seller packed this power supply very well to ensure safe arrival. Exactly as described. Well, some people might have trouble with a few things. Be aware when you buy this.
