Adding more connectors on a psu

[Somerandomtechyboi]

Not the adding connectors via splitting type of question but more like soldering on wires to the psu pcb itself

 

 

A dead psu for reference

Maybe i could solder some wires under the pcb? Or do i need to detatch a connector and then solder on the wires?

 

Main reason i wanna do this is for connecting high power devices like boost converters or tecs cause i do not want my cables to start melting, because i might be able to solder on some extra thicc cables that hopefully wont melt

 

The other part of the question is the connectors since soldering and desoldering constantly is inconvenient, could i just use one of those screw terminals? Cause not having a soldered connector on the device that im using would allow more versatility so i can do other stuff with it like jamming the wires into a molex xD

 

And also is there an easier way to do this? Maybe i could use a 6 pin instead and distribute the load over 6 wires instead of 2? But then howd i wire that up? Cause when i try 2 positive wires the psu just thinks its a short, maybe i need to have equal amounts of + and - wires connected?
