Corsair RMx Series, RM750x, 750W, Fully Modular Power Supply, 80 PLUS Gold Certified for $99.99
Not sure if this is a deal, but there is the Corsair RM750x, Fully Modular PSU for $99.99 from both Newegg and Amazon. Seems pretty cheap, lowest price is $89.99 occasionally on CCC. Usual price is $129.99.
I have the 850x and its solid. Very stable voltages
