No this is a brand new ASUS 650W, the old one was of the older types, cant remember which model but it was older. It was a 750W, but he is running a 1660TI and some older gen intel cpu, so power wise he should be plenty lf safe.
But he has a buddy that works in a offshore subsea company so they are gonna have a look at it and measure if there is any life in the mobo. Maybe it also got fried, but again wierd since there are two led on the mobo which are getting power when it is turned on.
