Which PSU should I use?

I have a recently assembled computer. I have been building for years. Currently, the machine is using my Corsair CX600 purchased December 2014 and in daily use since then running a Pentium G3258 machine with integrated video. It is now powering my 4790K and GTX 980.

I also have a Corsair HX850 which I purchased in December 2010. It has been in constant use since then and I have never drawn more than about 450W from it.

My question is, should I use the older higher quality PSU, or should I use the newer lower quality PSU?

Im leaning towards keeping the CX600 in the machine. I would like to hear other people's thoughts.

The HX 850 if it were me, purely from an efficiency point of view (600W is bronze VS the 850 being gold) a PC draws on the power it needs regardless of how much power the PSU can provide.

I would use the HX as it is a much better psu.

The HX is a better PSU, even if it dates back to 2010. If this is your main PC, put your best PSU in it.

Like what's been said above, definitely the HX850 with the new build.
