When i first built my rig around 1 year ago, i decided to get a Corsair 520HX because of its praise and modular cabling. I have since built several pc's for my friends and used either the 520 or 620HX in all of them. I will never buy another non-modular PSU either. Once you have one you will understand. To add to that, i needed another 6pin PCIE connector. I went to the CORSAIR forum and requested one via PM. It was promptly sent to me FREE OF CHARGE. Thank You Corsair!!!!
