This one is a dud! - Bought this on discount and didn't test it until past the return window. It struggled to boot multiple systems, and I sent it in for an RMA. The replacement unit is also unreliable, often failing to boot. Multiple other PSUs worked in place of it. Beyond that, the flat cables are bulky and not very cooperative, and the bigger bundles (like main ATX power, video, CPU) are an ugly and awkward mess with (presumably) various voltage rail bundles tangling themselves together. But the casing looks nice, I guess. RMA service was easy and fast. Have had good experience with previous Thermaltake PSUs so hopefully this model is just a lone aberration.
