Recently my PS5 has been shutting off as if the power has gone out when it hasn't where I then need to unplug and plug it back in for it to work again I've even changed to a different spot in the power brick and it still happens. What could be the problem and how can I fix?

It might be an overheating problem, check your console for debris build up and make sure it's in a place with good air flow, the PS5 by default has a pretty bad cooling design.

Ya not to sure I'm confident in opening it but I use vacuum hose around the vents and where it's at the back and front are open sections of the entertainment stand
