TL;DR : PC's 400W burned off because of overheating, i want to buy this one:
Amazon Link does it work with my system? Friend tried 650W and it worked, do i risk with 550W?

So this website is full of resources and i tried my best to understand how to get a new PSU, i even tried the calculator and the calculator gave me 200W total usage but suggested a 600W EVGA PSU, do i really need 600W?
This one here is my original PSU

Unfortunately it burned off, a friend of mine that checked the PC said it was because of overheating and not enough power, strange enough because i've been using it for 2 years without a problem, also apprently i got scammed when i bought it from amazon, these are the specs of my computer

Instead of a 600W as specified it's a 400W.
Also, the cables on modern computers should all be the same right? When removing the old PSU i counted 2 S-ATA cables, 2 HDD/DVD with 4 Pins, 1 VGA1 cable with 6 pins (3 up and 3 down) for the GPU and a 24 pin cable i guess for the motherboard.
Any help is greatly appreciated ty.

Thanks for the suggestion
