Any idea if 1200W will be OK for 4XR9 290 rig? I know for sure 1250W is enough and stable but don't know if this 50W would be crucial. Thank you!

There is a similar topic in the forum but I wanted to share my experience from today. Sent BTC from Bter to Cryptsy but entered my BTB address instead of the BTC. So the money were gone from Bter and never arrived at Cryptsy...
