When it came out, it was one of the only 50C rated modular PSUs with a single 120mm fan, excellent voltage regulation and low ripple/noise. It was on top of SilentPCReview.com's silent PSU list for quite a while...so I guess I'm curious as to what you disliked about it.
Not that it matters, but we had more problems with it when paired with heavy loads (overclocked rigs with CF/SLI), then we had with other similar contemporary PSUs. The cases were not predictable and sometimes one would work in one rig, and then another one would create problems in an equally specced rig elsewhere... I could never figure out what the problem was, and it may as well have not been the PSU's cause, but as some other brand PSUs at the time didn't display such whimsiness, I just didn't use them in most of the cases where a 620W PSU should have been enough.

I'm sorry I can't give you a more technical explanation, but it was all trial-and-error based and boiled down to a gut feeling.

The single-rail TXs are pure gold though and I'm only sorry I'm slowly running out of rigs to replace PSUs in...
