I bought this PSU (Corsair 1000HX) in Dec 2009. About 8 years old.


I have no issues with it yet, still going strong. But in 2015/2016 I upgraded FROM a i7-930 cpu, x58 mb, 2 480s SC, and 16gb DDR3 ram to i7-5930k cpu, x99 mb, 2 980s classifieds, 32gb DDR4 ram. I am wondering should I replace the PSU? Is there a need, unless it not working right? Will I benefit from a new PSU?


Check with a voltmeter if it's still putting out volts within specs. i believe std is 5% of spec. If you can visually inspect the capacitors for swelling without opening it up that can be a good indicator if it's about to die.
I get this below, instead of 12v I get 9.240v and with speedfan which is not below says 10.47v. Bios does show 12+v.

Sensors can be inaccurate. For your best results use an actual voltmeter on a 4 pin molex connector. Black lead on black. You should read near 12v from the yellow wire and near 5v from the red wire.
after 8 years it's just time to retire it to spare status, the older it gets the higher the risk of failure........
At efiloon - do not open up your Power Supply. If you have to ask this question, you probably shouldn't be messing around inside a power supply. :)

Excellent point EarthDog makes.......unless you have a good idea of what you are looking for probably best to stay out of the PSU......but you could still test as Blaylock says above....

This ^^^^ You'll get the information you need by following these directions. You can't hurt anything doing this.
Thanks everyone, yea its weak 12v, I have ordered a new PSU should be here in a couple of days. Sucks that I have to do cable management again as I just got done on a rebuild, guess I should've just gotten a new PSU to begin with....
Fortunately I'm still running 11-year old Corsair modular HX520's on my two Intel E7500 and E8500 machines and their 12V sides haven't wavered more than .1 volt (still about 11.92 - 12.16 respectively) with overall light usage. I'm not a power user and a modular fanless Seasonic 460W powers this 6600K and its light overclock. I had always wanted to try one of the top-tier fanless units.
