Corsair warranty

[Tray]

I have a Corsair TX850w psu that i
Would like to carry over into the next build but I am unsure how much
Warranty is left on the psu? Is there a way of finding our???

I brought it years ago and since this post I have googled this, and it says something about 1st 2 numbers is the year and then next 2 numbers is the week of the year as there 52 weeks, I think I found the numbers, the correct numbers and if it’s correct warranty runs out this year...I’m thinking Better being safe than sorry I’m best to get a new psu unit instead for the sake of a little under £100 it’s not worth the risk

Well I know I’ve had this psu for more than 7 years now and it’s been descent with out any problem what so ever, funny enough it’s has the yellow lettering on it so it could well be the inferior models as you stated...Think my best bet is 2 upgrade this psu and get another Corsair model you have posted...
One last question, will these psu fit into a Silverstone raven mini itx case with out any problems??
Once again ty for your replies and guidance
