"XFX 850W XXX PRO"
I have the 750w version of this PSU and while im extremely happy with it performance, the cable lengths are really short! The motherboard 24pin and 8pin especially ive had to send directly across the middle of my case just to reach where they need to be plugged in. I could obviously buy some extensions if i really wanted to do more cable management but its not an ideal situation.
Im using the coolermaster storm scout case. So if your using anything bigger, such as a full-tower case, i dont know that id recommend the XFX purely based on the cable lengths.
