My VS450 Corsair atx cabe conector is short and I connect it at the top of my mobo. Tomorrow my RX 480 arrives and if I install it my atx cabe wouldn't be able to reach the atx conector. I bought an 20 > 24 pin adapter but I don't trust it because there are 4 cabes left from my PSU so I think it'd cause energy problem to supply the power.

Is it an option to leave the PSU outside my case during the time my extensor cabe arrives? It arrives within two weeks.
 


This PSU has served me for three years how can it be bad being Corsair? I plan to change it only in January
