So well I had this short depth TFX case laying around having been already taken apart for the internals that were intended to be used in another housing, but after progressing so far the customer for that bailed and as it required his existing priopritary sized PSU housing to complete the housing and PSU has stayed in bits since.
So it seems like the ideal opportunity to start a little trial that I'd thought of a while ago but, like many things, its just getting a little time here and there to progress.
So many of you know FSP500-50FSPT. the 500W 1U flex ATX PSU. yes yes the one that screams like a monster on startup till it quietens down after a good few seconds and of course at full load with its 11krpm fan screams like a monster.
I'm not about to stop the cooling fan spinning up at full speed. But in moving the PSU in to a TFX case this enables an 80mm fan to be utilised for cooling and Its easy to get the same and greater levels of cooling cfm but with a massively reduced fan rpm and correlating levels of noise reduction.
Yes there are a few 500W TFX's PSU on the market, so why would we bother?
A. Because we can, so why not.
B. Having seen a couple of these supposed 500W PSU, cough, with passive PFC (230Vac on 115Vac mains only), they're probably about as likely to be able to deliver 500W of continous power as I am to run around the world in 24hours. As for their efficiency, passive pfc, at best a few points above 70% and that's on a good day.
So this is as far as I got really in 5 mins till the phone rang with an urgent requirement.
