there are very few TFX-specific chassis on the market that it can take advantage of.

Very true, although I have to admit that I am one of the few who have one (AOpen 360b). Sadly I've replaced my PSU in the last year (with a 220W FSP model) - if I hadn't this would definitely have been on my shopping list, although the price is a bit scary....

It wouldn't be much of an increase of price if they just included a TFX to ATX convention/adapter back plate. Would open it up to many other customers in the small case format.

Funnily enough that was my immediate thought - make it usable for those cases where you would normally use a bulkier ATX PSU and use the space saved to improve airflow.

The main argument against this PSU is its limited appeal; there are very few TFX-specific chassis on the market that it can take advantage of.

Quite. I've been looking for a NAS chassis, and they're either bulky ones using full ATX PSU's, or space-efficient ones that use SFX PSUs - which because they use 40mm fans are not the quietest.

In which case - to my mind at least - there's definitely a space for a chassis that was basically a shrunk version of the ATX-using ones, but used TFX instead. There's also those folks who want a mini-ITX PC, but would like it as small as possible. Something more capable than a NUC (or similar) but not a large (?!) as a Shuttle type enclosure.

What sort of Db count do you guys get from your power supplies? Looking for one for a silent build and I want my system to be as hush as possible

I'm going to ask a daft question - other than looking in the specs for a PSU how would I get a "Db count" from just the PSU? I've got case fans, heat sink fans, and that hefty one on my 7970 graphics card all adding to the overall noise.

I got a Corsair AX750 (full sized PSU) just over 3 years ago and that has a 120mm fan that's set to not spin at all until the PSU gets put under load, and then the speed is load dependent. So basically if I'm sitting doing mails etc, the fans not spinning and the PSU is silent. Problem is that a TFX design HAS to use small fans which means noisy. Unless someone out there has a PSU that can pull the same "load dependent fan" trick as my AX?

I don't think TFX>ATX brackets would work in a number of cases. SFX>ATX does work though and the Silverstone SFX PSU I purchased recently did come with such an adapter.
