Guys/girls. So I am taking apart a NAS and fitting in into a small PC case for better cooling. ATM the NAS has a 12v 3a PSU. However, Tre has very generously sent me a 300w PC PSU because I need a way of powering up the lights on the case, fans and etc. Now obviously I am going to gut Tre's PSU and only keep what I need but my biggest concern is the NAS itself. I know this is a stupid question but I'm a worrier so I figured I would ask any way. If the NAS uses 12v @ 3a would it be safe to lop off the power connector and fit it to the PC PSU? obviously the PC PSU has a much higher AMP rating but if I'm correct in thinking the NAS will only use what it needs yes? So as stupid as I am for answering my own question (sorta) it would work and be safe so long as I get the polarity correct, yes? Obviously I could use two power sources but it would be much cleaner if I can use one.
