PSU Too old?

[OhThatsDaddy]

Hey guys, I'm having an issue with my pc where when I boot up a game my monitor turns off and my other monitor freezes and the only way to fix my PC is to turn it off by the button, this only happened after installing my new GPU, does anyone know why this could be happening? (I don't know if it happens with other games as those are the only two I've been playing) also this only happens every 1 in 5 times

I did some searching up and I thought it might be PSU related? I have a really old psu (
SeaSonic SS-750AM 750W PSU Modular 12cm Silent Fan ATX12V / EPS12V SLI Ready 80+ Bronze DC-DC)
it's 750w though and this problem only started to happen after I got my new 3070. DO you think this could be the problem? and if so do I need to get a new psu and if so do i need higher then 750? I was told 750 would have been fine
I have a 3070 FE

Thanks in advance

Hello
Its a distinct possibility that its not up to the task of powering your new GPU, thought it might have done when it was new. The M12II range was its base line fully modular range back in the day. Doesn't mean to say it was bad though because Seasonic's budget range at the time was better than a fair few other makes higher range of PSU.

Replace it with another Seasonic, gold rated this time, 750w will be up to the task.
