I wanted to ask this question regarding old power supply because there was an era where motherboards demanded a lot of amps on the 5v line.
Like for example Athlon XP. (im not sure if pentium4 required that since those motherboards already came with a P4 connector)
So in order to build a machine from that era you need good Power supply with many amps on the 5v, maybe 40amps or 50amps.
While the ones being sold today.....the amps on the 5v is less than 25.
every now and then i find one of those old power supply, but sadly after so many years, when you open them many of the capacitors are bulged (it was a time where many caps were fake), or even if the cap has no bad signs if you take it out and measure the UF is extremely low and not even close to the markings.
a problem that is known is the area, the space of the power supply pcb. Many original caps tend to be with a smaller width, and taller. Some caps have the same width as the replacement but the replacement is not tall (what is the difference i trully don´t know) . but the area problem might be easly fixable by printing like a smaller base on a 3d printer with 2 holes (like a plastic tube with 2 holes and on top of that you insert the new capacitor), tomake it fit the small area on the pcb, since the new caps legs are very long.
So would you fix an old power supply? would you replace all caps?
