Howdy,
I am switching over to 1300 watt EVGA PSU's, so I am selling 4 of my Seasonic 550 Gold PSU's.
This is the PSU:

I'll provide free UPS ground shipping to US lower-48.
If you want faster shipping, you can send me a shipping label. I'll ship from zip code 74014.
If you'd like to do escrow, my preferred agent is vnhyp0 who I have transacted a few dozen bitcoins with over the last 10 months.
