    Very disappointed I'm not to sure who to blame either Corsair or Best buy. I have been building my custom PC for the past 2 weeks i bought this product it never worked. ended up buying the same product but in black to see it was just a dud both didn't work. i had to buy best buy total tech membership so they can check out the pc just for them to tell me that both power sources that they sold me both by corsair were duds as soon as they connected a different power source the PC turned on. Very Very disappointing and a waste of my money.

    I bought this for use with a Corsair 5000x case. All the cables look high qualitiy but they are EXTREMELY short on on the motherboard / CPU cables and the PCIe cables. Not a great look.

    i replaced a 700w with this 850w and after 2 months it started making a loud buzzing noise. Best Buy will not do a return after 14 days which is ridiculous. i will not shop at Bust Buy again
