Repair Questions (Need Help)

[jafert23]

Hello, this is my first post to the forums so please bear with me
(PC components will be at the end of the post for reference)

I took my desktop computer into a repair store to be diagnosed, because it wouldn't display graphics either through the motherboard or the graphics card. The store recommended that I replace the motherboard, which I did. This did not fix the issue. At the moment, I'm pretty sure that the issue is the power supply. I calculated the max power draw of my system through an online calculator, the power usage was about 600 watts. My current power supply is only 450 watts. This computer, which I bought pre-built, has internal cable routing underneath a metal plate (it's riveted down so I can't easily access the cables underneath and the plastic connectors at the end of the cords don't fit under the plate). I would like some advice before I go crazy with my scissors and cut up the power cords. Thank you for your help!!

Question 1: Is my assumption correct that I need a new power supply?
Question 2: If I do need a new power supply, is it safe to cut the ends off the cords(assuming I won't need to use that power supply again)

CPU: i7-6700k
GPU: AMD Radeon rx-480
PSU: non-branded 450watt
Motherboard: ROG Maximus VIII Ranger
Storage:
-128gb SSD
-1Tb, 7200rpm hard drive
CD/DVD read/write drive
(Hopefully this is enough information)

Thanks again!!

I would definitely get a new power supply and test it. You can leave the cord there and test the new supply and let it sit outside the case, and if everything works as intended, cut the cable out or just leave it there, since it isn't like you can use the space.
