IIfx power supply voltages?

[Von]

Hi All,

The IIfx is in queue and I am trying to find out if my power supply is putting out proper voltage.  I have one board that will start the PS and when I test it I get:

5 Reds: 5.13

1 Yellow: 12.14

1 Blue: -12.11

1 White: 4.23

Is anything off here?  

THx!

The white wire (5V) is too low I would say and the rest a tiny bit too high. Has it been recapped?

Is the LB you're using to test the PSU working correctly? If not, it might draw too much on the 5V...

I have not opened the IIfx PS as this is relatively new to me and I don't know if it has been.  I will crack it open today if time allows.

As to the tester, it is not a top-shelf model but has served fine on my replacements for SE/30, IIsi and IIci power supplies with SeaSonic PS as recapping is not in my skill set.

I would think the slightly higher voltage would be OK if you load the system up with expansion cards. The IIfx PSU barely cuts it when you have tons of high power cards installed. .10 over is within tolerances, although kind of on the hot side. Monitor ASIC temps and make sure no chips are burning hot.
