Not sure if this counts as hot deal but:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151088&Tpk=Seasonic%20x650
Amazon has the x650 going for ~$180 or so.
Newegg has it going for $139, and there's a promo code (EMCKGHE78) to get $30 until March 31. Assuming that works, that's $109 for the PSU, with free shipping!
My guess, Newegg is clearing stock in light of the new x560, x660, x760 launch.
So, anyways, that's part 1, notifying you of what I think is a deal here.
