How do I get the power good line???
my mobo needs it...
first: be patient, it's a friday night/saturday morning and some of us actually have lives
second: the power good line is +5volts.
try and be a little mor epatiwent next time
Sorry for being inpatient...
that is not so...
The power good line is a 100-500milisecond pulse of five volts...
I think, well, that's what this website said....
just conecting 5volts doesn't work....
Try 5 volts and see if it works,
use a cap and a resistor with the resistor tied to +5 and the minus side of cap tied to ground and the middle of them is the power good signal.
use a buffer chip or 2 inverters with the R and C in the same manner.
Remember, T = R*C
Thats time equals Resistance times capacitance. wooo hooo!

I will try STEP B, but I don't think it will work......
any more ideas??
Hi Again SKINNY,
The cap and resistor work just fine. That is what I have. Use a 1MEG resistor and a 1uF cap for a TC of 1 second.
Hey give the kid a break. My mobo didnt work even with a resistor+cap. In the end I needed to use and opamp to square up the pulse.
Somebody else asked for the circuit. I'll post the diagram when I get back home after this weekend.
How does a resistor and a capatitor give a pulse????
