Question Is this safe? Can i turn on my pc doing this?

i changed my power supply
What did you have prior and what did you change to?

So long as all the connectors are properly seated and at their intended ports on devices(and the PSU isn't a second hand unit, I'm assuming that's s 700W unit by EVGA though clarity from your end would be appreciated), you should be fine to power up the system.

Please list the specs to your build like so:

SSD/HDD:

PSU:

Monitor:
