No boot with SATA connected

[Dale Brisket]

My new dual core system won't boot (shuts down immediately after power on)
only when I connect a SATA II drive's power connector. No problem with PATA
drives. Any ideas? Specs below.

Asus A8n-VM CSM (onboard nVidia GeForce 6150)
1 GB (2x512) Patriot Signature PC3200
Antec NeoHE 430W PS
Hitachi T7K250 SATA II

Only other peripherals are a floppy drive and CD-ROM. I know the PS is a
modular, but is it likely to be the culprit here? TIA.

Either the power supply is deciding that it doesnt like the
current draw from by the SATA drive because its dead,
or the current sense by the power supply is defective
and its shutting down because its decided that the
current draw of the SATA drive is too high when it isnt.

The easiest check is to see what happens if
you put the SATA drive into a different system.

Yes, that is one real possibility.

OK, will put the drive in another system and put another power supply in
this system. That ought to pin it down. Thanks.

Turned out to be the PSU. It's now running with a non-modular 400W and all
is well.

Thanks for the feedback, too rare in my opinion.

Yes, if I had ordered that PSU on another day, I probably would have gotten
a good one. Luck of the draw, I guess.
