Hey I recently bought a GPU that requires a single 8 pin power connector but my Psu is a little old and has only a 6 pin connector,so I bought a 6 pin to 2x 6+2 pin adapter (the only thing I found locally) and was wondering if leaving one of the 6+2 pins to hang without connecting it to anything will cause any problems or I will need to buy a 6 pin to single 6+2 adapter.
