Which psu? Corsair RM series worth?

[Akonovo]

Hi, im looking for a decent PSU for this setup: gtx 770, 4790k@4.6ghz
The point is that my current psu is failing and I need a new one. Ive been looking for Corsair RM series, but they are expensive and I dont know if worth the cost. (its a Quiet/Sillent PC)

Which PSU do you recommend?

Ive also heard about Seasonic PSUs. are them better than corsair in price:quality ratio? (I want a PSU that last for years without burning up)

check out the EVGA Supernova G2 750W Gold fully modular unit. It's normally quite cheap and is one of the most reliable PSU's at that watt range.
