My "stealth" IIsi PSU arrived today! [:D] ]'>

HP Pavilion Slimline s3200n s3000 s3100n Power Supply

I'll post some pics, mine's black (at least the empty sheet metal is black, mine's naked ATM) manufactured by APEVIA Model ITX-AP250W

250W Continuous Power Rating

6A input vs. the IIsi's 4.2A

15A on the +5V rail vs. the IIsi's 6.8A

16A on the +12V rail vs. the IIsi's .8A

-12V rails are the same at .03A

2A +5Vsb vs. 1mA +5VPSTRICL (whatever the heck THAT means)

16A on a useless 3.3V rail

With a little filed off of the sides of the PCB, it should nest inside the IIsi PSU's original Sheet Metal facing upside down. Putting it upside down clears the cubic necessary for the original power plug to be reinstalled in place and more cubic remaining in the back for the original power plug block and a relay equipped Switched PSU adapter PCB.

I didn't expect it to arrive quite yet, but I stopped by Radio Shack and picked up:

SPDT-Miniature

PC Relay

12VDC coil

Rated 10A at 120VAC/24VDC

. . . it must be te good stuff: "Made in Taiwan" :approve:

. . . mainland China can kiss my ( | )

. . . so three guesses as to where the PSU was made for HP . . . ::)

Be that as it may . . . does this sound like the right relay for the job?

I think I'll be putting the two fuses Sony placed in the original PSU for AC input and output to the monitor plug on the adapter PCB . . .

. . . apparently this feature was overlooked.
