I just bought an Intellijel 7U 104hp case from Schneiders. It came with a US power cord.
I googled a bit and I think that the power supply uses a C13 plug. (Can someone confirm this?)
I will of course use the included power supply. Im only talking about the cord itself.
But my main question is wether or not it is safe to just buy another cord that fits the power supply and can be used in EU/Sweden?
Yes, you just need to purchase the regional cord to use with the Meanwell power brick.
The Meanwell bricks are able to use inputs ranging from 100 - 240VAC and 50/60Hz, so they can be used internationally.
