PSU is dying :( I need suggestions!

[FishesDelicious]

So my PSU started pumping out some really nasty smelling burning stench today. Poor guy made it 7 years with me. Now I need some suggestions for wattage and model for a new one.

CPU: i5-4770k (not much overclocking, but the potential to would be nice)
GPU: GTX 780 ti

I've read that 500 is fine for it, but then someone comes in an argues that no, 600 is what it will need. Then someone else comes in and says no, 650...blahblah you know how it goes.

Any help is much appreciated!

well the manufacturer says that 250 watts is needed for the gpu and 600 watts for the system

if you want to overclock everything then i would get a good 750watt power supply

as far as recomendations you can never go wrong with a seasonic or xfx (seasonic makes the xfx power supplies)

this is a good quick list and all articles have great reference material

nvidia's exact words
"600 watt or greater power supply with a minimum of 42 amps on the +12 volt rail."

the ampere rating is more important than the watt rating. you can have a shitty "800 watt" PSU that will blow up if it tried to power a GTX 780 Ti because the 12V simply cannot handle the load. at the same time, a super high quality 550 watt platinum rated PSU can power a GTX 780 Ti without a problem.

so, in reality the answer is not so simple. if you are buying a regular "bronze rated" PSU, go for 600 or better.
