sorry to hear the bad news. haven't heard of or researched that model. quick assumption, probably dual rail, probably can't handle 2 cards *edit = modules* on the same rail.

My advice to anyone buying a PSU for avalon (or even for normal computer) -- DON'T CHEAP OUT! I don't care if it's twice the price, After 2 PSU failures (second one blew the motherboard) I will never buy cheap PSU again.
