I'll be upgrading my aging GTX460 later in the year (probably an Nvidia GTX 7 or 8 series) and wondered whether I should upgrade my PSU or not first. I'm currently running a Corsair HX520 which has been rock solid and quiet as a mouse. I've read that it should be fine for anything up to and including a Titan :eek: but wanted to run it by OcUK first.

Current Spec
Bitfenix Prodigy
i5-4670k
2 x 4GB
ASUS Z87i-Pro
Gigabyte GTX460 1GB
Corsair M4
Western Digital 1TB
Corsair H100i

eXtreme Power Supply Calculator suggests my current system at full load pulls around 405w, not sure if that's accurate or not but I don't have anything overclocked at the moment.

If I get a new PSU the requirements will be 160mm or less in length, as quiet or quieter than my HX520 and modular. I've read a few reviews and group tests and the Seasonic M1211 620W and X-Series 650W come out quite well.

Thoughts? :)
 
You should be fine with a single gpu with that psu.

The rig in the video below has a GTX 780ti and an overclocked i5 4670K running off a Corsair RM 450W.

 
your psu is fine.
i'm running a 3770k @ 4.2ghz, and a 7990 with a full watercooling loop in a prodigy all being powered by a 650w psu
