Well with a power supply company as highly regarded as PCP&C and if there is no negative things besides possibly cost to using modular PSU's, then why doesn't PCP&C make modular PSU's? Or for that matter, why doesn't every PSU maker use modular if there are no drawbacks? Seems kind of stupid to be making non-modular if you can get better cable management and the same performance and quality with a modular design.
So if all companies aren't making modular, there must be a reason, right? So they can trick the consumer into thinking their PSU is better because it doesn't use modular? That just seems like a dumb business model to me. There must be a legitimate reason as to why all companies don't use modular if in fact there is no difference in quality.
You'll find that almost every PSU in Europe is modular. Why? Because Ultra only has a U.S. patent. There's actually many more brands in Europe than there are in the U.S. Even Cooler Master happily distributes modular versions of the Real Power Pro in Europe while sticking with fixed cable versions here in the states.
