Modern PSU for the SE/30

Recommended Posts

@Crutch Did you measure voltage levels (specifically, the 5V line) at the Floppy connector and at your internal HDD power connector when you had your Turbo040 inside?  I ask because in my experience, prior to my epic blunder which caused my Turbo040 to stop working, I would only get freezes with the Turbo040 when there were software incompatibles.  That's a lot of software that just locks up with an 040 but which works fine with an 030 processor.

@Crutch your solution of wiring the soft power of the Seasonic to the original switch is very elegant - I wish I had of read your post in more detail before I did my upgrade!

That is how I wired mine as well. The only downside though is I'm still hesitant to leave the computer plugged in when I'm not using it. If I had wired the PSU AC power to the physical switch I probably wouldn't think anything of it as turning the Mac off would mean it's off, full stop.

That's how I have my SEASONIC wired.  When the mechanical switch is flipped OFF, the PSU is 100% OFF and has no possibility of ever going ON.  I didn't think anything negative about doing it that way since that is basically how the stock PSU works.

There's definitely pros and cons of both methods. I think for a novice like me, wiring the soft power would have been easier and less scary. I guess I'm just paranoid!

 

Although I was wondering how hard it would be to get the soft power running to the power key on the keyboard?!?
