ive got quite bad coil whine, its not high pitched but low pitched and you can hear it whenever you put the psu on any load above around about 180w
100% its the PSU as before i had my Antec 380w psu and that was quiet with no coil whine, the GPU has a higher pitched whine but its stopped doing that, should i keep the wires as its a modular power supply?
If you RMA a PSU, you must include all the bundled cables. Those will be the warranty terms so stick to them.
do i return it to amazon or corsair, because i bought it off amazon using their prime one day delivery, apparently its quite easy to do an RMA with amazon.
if its within the retailers return period, try them first, if they dont help then you go to manufacturer
