FAULTY 4x 1200W Platinum PSUs Corsair, Kolink, Superflower FAULTY

4x 1200W Platinum FAULTY PSUs. Corsair AX1200i : self-test function fails. Has been opened up- no obvious signs of damage, but PSUs aren't really my Mastermind topic. Comes with some cables- enough to put together a basic PC.

Has some scuffs as can be seen. 2x Kolink Continuum 1200: one has been tested and promptly blew up a graphics card. The mains cable was hot, with softened sleeving so something is clearly wrong with the unit. The second one has not been tried. When either of these Kolink units have their green & black pins shorted, the fan spins....

But removing the jumper or turning the PSUs off at the switch doesn't stop the fan. Also included: 10x 8-pin GPU extension cables. These do NOT split into 6+2.
