Thanks!
Seriously, why did you buy it without a power supply if you don't have enough technical knowledge to spec. one out?
He does have enough technical knowledge. However he is asking for ADVICE from those who have more up to date model knowledge.
He knows:
He needs a PSU
He needs an ATX layout PSU
He needs a high eff PSU
He needs a 700>W PSU
but he wants to know if anyone has any recommendations or known to work [should be all] when powering his $6000 PC.
And he has been told the answer 5 times now. But he wants to waste Avalon's time by getting another answer from them.
So to make it dead simple:
Buy a top quality Gold rated PSU rated at LEAST 25% higher than the power required by the Avalon you ordered.
Go to Anandtech or 100 other hardware enthusiast sites and do your research.
