PSU Warranty

I bought an Antec Truepower 650 with a 5 year warranty about a year ago. After 2 months it started making a buzzing noise so Scan kindly replaced it. The replacement was also buzzing so Scan offered me to choose another brand psu so I chose the Corsair 650HX which has a 7 year warranty.

So does my PSU have a 5 year or 7 year warranty?

Did you pay any upgrade or was it a straight swap? if the latter it would be covered by a 5 year warranty which started on the original invoice date.

Regards

or take it up with corsair they would prob say 7 ...but that's with them not scan ...
