Basilisk v3 hyperspeed dongle crashed my pc

My pc was failing to power on at all. Swapped the power cord, tried other outlets...nothing! Finally I start to unscrew the case and see i didn't take the USB dongle out, so I did. I plug it in, press power button and 💥  BOOM powers out immediately! Looked this up. How is it possible a usb dongle is capable of controlling the entire power supply to a computer?! Once I realized it was the issue I thought back and realized that my games have been crashing, the mouse is glitch too. I have only ha this mouse about a month or so. Only reason I bought it is bc my Razer deathadder mouse scroll wheel stopped working! Come on Razer,you'll really need to get it together man! All of my equipment and hardware is Razer. .but now after all this I'm really starting to consider an entire brand change! Also, my mice need to be replaces! And I'm not savvy enough to mess around with power supply and graphics cards etc. So eventually I would've had to buy a new pc. What would've happened then? If I didn't figure out that YOUR usb dongle corrupted my pc? Would you have replaced my $2000 computer!?
