PSU Shorted, Possibly more

Shorted PSU, possibly more

Made a huge fuck up. Of all things PC related I know, I had no idea that Modular PSU cables are to only use cables from their manufacturer, which is where I made a mistake. As of now, I connected a “universal” third party PSU-SATA connector to power my Corsair command fan hub, and Corsair case RGB lighting. When turning the pc on, instantly heard a shorting noise come from the PSU and a smell of smoke. My questions is where to go from here to trouble shoot components. I have already bought another PSU, but was told that if I directly connect this up and try to boot I could end up shorting the new PSU if one of my other components are shorted. So, I don’t know where to go from here as I have a friends PC I could start in steering my GPU, RAM, HDD, And SSD in. But if one of those pieces are “fucked” could it possibly short components on his PC? and how would I check the motherboard without connecting it to the PSU “if” the motherboard may be shorted, and hence end up shorting the new PSU? Very confused on where to go from here, would highly appreciate some help.

your motherboard could be dead but your hdd and ssd are prob dead because there directly connected to your psu. if you have another system try and boot your drives and see if they boot if not your drives are dead. your cpu and gpu should be ok same with your ram. my recmmndation would be to buy a new motherboard and if you have a secondary system try to boot all of your components and you could find your short if there is any
