One brand approach is usually easier, though you match power cord and particular component, so it might not be the best approach. However, mixing and matching different brands can be a nightmare. I would try to avoid it if I could.
PC manufacturers?
I prefer to buy my power cables used. I look for cables that are in good condition, well reviewed and fair priced. As I look at my collection, I have a mix of manufacturers and I wonder if that's a good approach...My question, should I find a brand I like and stick with it throughout my system or is reasonable to mix quality cables?
