I am starting to think about converting my Sawtooth to run from an ATX PSU. The original Astec PSU still works OK but its 23 years old and probably getting toward the end of its life now.
The challenge as I see it is how to achieve a neat/OEM look, in terms of: no case modification, retaining the rear mounted fan, etc.
Hardly any modern ATX PSUs have a rear fan, they all have a fan on the top/bottom of the unit. A lot of the ones I'm looking at are modular but I'm not sure how those will fit.
I am not sure that even an SFX PSU will fit inside the original Astec unit, at least not without modification.
My requirements are something 80 plus gold/platinum rated, with good ripple, efficiency at lower loads, regulated rails, all the modern safety/protection features, high quality caps/components, probably 300-500W (the original Astec model in my Sawtooth is 237W).
I did notice the Astec unit is rated for 24A on the 3.3V rail - the highest I've seen in an ATX PSU that would be suitable is 22A.
Most documentation of converting a G4 to run from an ATX cover the MDD model, not Sawtooth, so any thoughts at all are welcome.
