    The side interface is amazing. Makes plugging everything in easy. Make sure you have a larger case that can support everything coming out the side instead of the front

    recommend, some motherboards require 2x 8 pins for power and this is the minimum wattage that includes the extra for it.

    Missing PSU power cord - Unusable

    Purchased this item in store at the South Loop Chicago location. Using my Total Tech membership, a Geek Squad agent put it in my new build. Unfortunately, when they handed me the PC they were busy and we couldn't test it in-store. They did give the original box with leftover cables but it did not come with the power cord to connect to an outlet. After all the above happened, I have spent approx. 2.5 hours (yes, two and a half hours!) on the phone and chat to no avail. Everybody passes the buck, says its another department and I have gotten no resolutions. It is ludicrous to pay for Total Tech membership, be guaranteed 24/7 Geek Squad support and get 0 help. Case IDs 315234763, 315235071, and CAS-15041662-W8F3N9.

      Hello,

      This would be an issue with the Geek Squad and not our product, please continue to work with them to solve this issue and review their service on the appropriate channels.

    Cords are shorter than you would think so I had to run several on the front side of the case. A few inches longer would have been great. I thought the side mounted wires was weird but maybe would work good for me, it didn't. I wish id have bought another (used) evga t2 instead of this.

    Worked well for less than 24 hours. Playing farming simulator 22 of all things and everything shut off. The power supply gave off burnt electronics smell and would not power back on. I put in the old power supply and everything came back up normally.
