I remember this lost thread originally before the forum crash and would like to revive it to see if anyone has advice on PSU alternative. If I want to replace the inner stock PSU PCB (and keep the original sheetmetal enclosure) with another higher wattage PSU, does anyone have a recommendation or pointers to look out for spec-wise? I am looking at the Artmix "stregthened" PSU as a guide on what to look for in a replacement. He has one that is 145W+20W and has two separate 12V rails (an extra for CRT sweep to minimize noise), while implying the stock PSU has one 12V rail. Finding a quad output, 5V, 12V, 12V, -12V PSU seems to be difficult (as JDW mentioned earlier) for the physical size constraint and also tend to be expensive. What would be really necessary to get a better PSU installed for configurations that have multiple PDS cards installed? Any thermal considerations for going bigger?
