Title.

So yes, today my Silverstone 750w PSU decided to start new year with some fireworks show.

I changed the place of my pc to another desk, did put all the cables (power, monitors, kbm etc) and turned it on. It did turn all the LEDs on and fans did function but did monitors didnt receive any signal, so i restarted the system and boom, flash from the psu, burnt electric smell and the system shut down. and I immediately did tear the system apart and started checking for marks of damage.

Luckily, no visible signs of any kind of damage, so I decided to try to run it with my second PC PSU, and it did boot without issues.

Now the question is, can I somehow see if the gpu do work too, before I get new PSU? My other system PSU is 300W only, which I believe is not enough to power up a RTX 2070s.

System specs fyi;
i7-7700k
Asus prime z270
Hyperx predator 36gb 3400
RTX 2070s
