Question about CableMod PRO Extension Kit

These are extensions, not cables that you plug directly into the power supply. Therefore they fit any standard cable. You just have to check if everything you need in your system is included. Included are:
‧ 24-pin ATX - 3 closed combs
8-pin EPS - 2 closed combs
‧ 4+4 pin EPS - 2 x 8-pin / 2 x 4-pin hybrid combs
‧ 8-pin PCI-e - 3 closed combs
‧ 6-pin PCI-e - 3 closed combs
