Obviously will not hold anyone to anything.

I have a Corsair HX850w semi modular PSU that is about 7 years old, has had a lot of use in my PC over the years.

At the time this was Corsair's second tier PSU below the AX (I think?) and shipped with a 7 year warranty. According to my mate who is an electrical engineer it has some double circuity?????? Apparently that is a good thing.

So, my question.

Put that in a new build?
 
Are there any obvious signs of problems like being full of dust or rattly fan ? What"s the new build going to be ?

You can argue both ways. I re-used a Corsair PSU in a Ryzen 3600 build recently quite happily, but the intent was to keep cost low. If you're laying out a few grand, then circa £100 quid on a PSU is small change.
 
It would depend on the spec of the new build. If its 3rd Gen AMD Threadripper & 2 x 2080Ti then no (I put this kind of spec in purely as an example)
Cheaper build such as say a AMD R5 3600 or Intel 9600/9700 & AMD 5700 or Nvidia 2060 super then I would say it would be OK but only at stock speed.
 
On a higher-end build, I'd be wanting brand new.

Wouldn't risk £1000+ worth of gear for the sake of £100 on a PSU personally.

A little second-system or htpc, then yes, I'd consider using the old one.

That's just my opinion !
 
It would be something like a Ryzen 7 3700x say, 16/32GB ram and a motherboard.

Old hardware would then be a EVGA 1070 and a couple of drives.

Wattage wise 850 would be way over, it is currently now also I only went 850 as I used to run crossfire years ago.

Maybe £500-£600 of new hardware in other words.
 
it'll be fine even if the 1070 was overclocked.
the hx 850w 2013 is/was a decent unit so i can't see any issues with it, even being 7 years old

Oh yeah, the PSU. You can guarantee that in 7 years time or whenever, you decide to upgrade the first thing someone will ask will be how old is your PSU, and then the'll draw in air through their teeth, just like a mechanic would and say, "best replace it just to be safe".
