Alternative Power Supply for Intel SC5200 Base

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
I need to upgrade the power supply of an SC5200 Base (450W) chassis,
the only Intel option is to buy the SC5200 HS Server Chassis (650W
2+1,Hot Swap,RPSU Ready) which is a bit expensive.  Is there any power
supplies out there that have the same dimensions of the standard 450W
PSU in the base chassis?  I'm sure there must some generic more
'economical' option out there ;)

Not generic, that's a specialized PSU that will cost quite a
bit more than anything standard.  Then again, when it claims
"450W", that's usually TRUE watts, not optimistic ratings of
momentary peak wattage like with a PC ATX supply- it's
form-factor is just too small to sustain 450W long term.  I
think they do come in smaller than 450W size though, but
you'll have to detmine for yourself if something in a 350W,
if available, will suffice for the system.

might be something useful here too (or maybe not, i don't
know), /

Thanks, problem is I need more wattage ... chassis is driving a Dual
Zeon, 6 SCSI drives, 1 Seagate IDE drive, DAT tape drive, 1 cdrom
drive,  2 Fans system.  That according to my calculations is pushing
the 450W supply, I also get these 'unexpected' reboots ... I imagine it
is the PSU resetting when all the devices draw close to 100% power
simultanously ... a theory, not sure if it is the case but would like
to eliminate power issues;)

That sounds a little high, it's probably not using more than
350W, actually less than that but considering a margin...

How are you calculating this?
Under what scenarios (system load) is it rebooting?
I would expect that initial power-on is the peak load, while
drives are spinning up.  Then once you have it in a modern
OS, ACPI should be mostly idling the CPUs unless this box
has a pretty heavy load.

You need to collect some data.  Multimeter readings of
voltage levels in recreated scenarios, logs from operating
system, load-reduction from temporary removal (unplugging)
of parts.

If you're still considering what was happening with the PSU
that failed, it could've simply been that one specimen of
PSU, not indicative of anything else in particular.  Does
the failed unit have the serial or model numbers
corresponding to that Intel failed-diode document?
