Can this adapter work on a HO SSA70 DL 580 1200w power supply?

I have been trying to get someone in Minersource to give me any kind of status on a preorder that I placed int September for Octoberfor delivery. I paid for the item with BTC and received an email with a receipt for the money. But still no response on any of my emails. Not even a status report. Has anyone been able to reach these people?
