PSU makers: Modular power supplies are less efficient

PC Power & Cooling doesn't make modular power supplies over fears performance and reliability, they've stood alone on this for several years but it appears other power supply makers agree units with hard-wired cables are better. Tom's Hardware spoke to Enermax, Seasonic and Corsair at Computex and heard that if you want to achieve the highest efficiency, you need to go for a non-modular PSU.

Despite modular power supplies being a hot product, don't be quick to grab the up-take. The companies we spoke to told us that modular power supplies are less efficient than those that have their cables hard-wired. The reason being that the extra connection you make, adds resistance, and hence, increases heat and reduces efficiency.

Enermax, Seasonic, and Corsair all told us that if you're looking to maximize efficiency, go for a non-modular PSU.
