The fan negative is in fact connected through a jumper wire straight to ground. It seems to be providing a minimum load on the +3.3V rail (and actually measures about 4 ohms). The large power resistor is nothing to do with the fan.

Edit: I made a mistake and traced the circuitry wrong on the PCB. If, for some very unlikely reasons, the embedded micro-controller or the current sensor fails, the ATX2AT Smart Converter also includes two very fast acting. Could it be an NTC thermistor? I've never seen one in such a large axial resistor package. Markings on the resistor seem to indicate it's 31 ohms, but measures as a dead short.

The positive terminal of the fan connection is straight to the +12V rail, and the negative has a large (1W? 3W?) power resistor in series to ground. But looking at the circuitry, I can't decide whether that's a lie or not. Speaking of the fan, the PSU's label proudly states it has 'thermostatic fan control'. heatsink) when the PSU is on - and it's even right in the path of the fan airflow. I'm thinking of replacing it with something with a longer lifespan rating - maybe 5000h. Would the ripple current rating come into play? It is rated for 1A.

Intel BX, Pentium II/ III und sehr oft mit ner Rage128 Pro kombiniert. I guess this means it is likely to have been powered up for far longer periods than the other caps, but is this the sole reason? I don't think it would see anything in the way of transient loads. Bis Ende der 90er haben se wirklich gute Systeme gebaut. So why has it degraded the worst? I traced the circuitry, and it is directly on the output of the +5VSB rail.

ATX2AT es una forma de reemplazar de manera segura algunas fuentes de alimentación obsoletas con una fuente de alimentación ATX estándar para computadora. I managed to track down a datasheet for it (G-LUXON LZ series) and it seems to be one that is more highly specified than any of the others in the PSU: 3000h 105C, high-frequency low-ESR (ESR is specified at 100kHz rather than the usual 120Hz). Para abordar esto, Doc TB diseñó el Smart Converter ATX2AT como un proyecto de código abierto y recientemente decidió ponerlo a disposición a través de una campaña de Kickstarter. What intrigues me though, is why one particular cap was so much more bulged than the others. Anyway, one of the main points of evidence that this PSU was getting tired was bulging electrolytic capacitors. Perhaps a typo, and it is meant to say '1.3'. Bizarrely, though, the PCB silkscreen proclaims it is 'ATX Ver 2.3', but there's no way it can be, because that standard revision wasn't even created until 5 years after this PSU was made.

I decided this one is worth saving because it is early ATX standards compliant, and features the full complement of voltage rails that includes -5V.

I'm in the process of re-capping an old ATX power supply.
