    Smooth, fast communication and very helpful in chat. MVP Carrie! If there is one thing that was sort of a bummer for me, it was this: - Moddiy asks what brand & model you got on your PSU. - After i've selected the correct one, and went for a FULL cablekit for the specific PSU, there was still one cable missing. Asus Loki PSU's comes with this 2-pin cable to control the RGB-fan inside. This small 2-pin cable was NOT inclueded.. it's not the whole world.. but it would have given me that extra extra feeling of service, that moddiy really thought of it all. But, im VERY happy with the overall result otherwise, and hopefully this small 2-pin can be added into the set for ASUS ROG LOKI Platinum PSU's in the future.

    Easy and quick experience. Only needed to buy one item and there was no shipping cost or even sales tax. I was able to checkout as a guest and use PayPal which was very convenient.
