Hiya!
I have finally come around to replace my aging AT psu on my p1 machine with an ATX one (mobo has support for both).
I began testing some of the first era ATX psus that have the -5v line (since I have installed a LAPC-I) and I see that 4 out of 5 that I own actually deliver -4.50v on said line (measured on the pins of the ATX plug directly) , the one that delivers -5.02v has the "noisy transformer syndrome" (you can hear a faint bbbzzzzttt when the psu has power connected regardless if the machine is turned on or off).
Anyone knows if -4.5v is sufficient (0.5A) ? obviously I don't want to damage or reduce the life span of the LAPC-I....
thanks for any info! 😊
