Looking for a bit of advice. My A3 antminer is only arriving tomorrow-the joys of living on the western edge of Europe!

Now the real pain is that I've found out today that bitmain only dispatched the Apw3++ psu today (despite numerous tickets requesting that both the psu and miner be shipped together). Anyway I'm looking at another 10 days or so before the psu arrives. Not great.

I have a Corsair HX1000i psu (i.e. 1000W) running on my ethereum rig. My question is, would it possible to use this psu on the antminer a3 and underclock the A3 until the Apw++ arrives? Any advice welcome!
