The new CS series will be the most affordable modular power supply with an 80 PLUS Gold certification available from Corsair. The power supplies are semi-modular, since the 24 pin and 8 pin motherboard power cables cannot be removed. The other cables are flat and sleeved as well as clearly labeled to help expedite installation.
Although designed primarily for low and mid-range PCs, the CS series claims to be "multi-GPU ready" and is available in 750 W ($119.99), 650 W ($109.99), 550 W ($99.99), and 450 W ($89.99) options. Each model is backed by a 3 year warranty.
