we'd know what to buy. I mean: SuperMicro just says ATX with the obviously
non-ATX combo of 4-pin + 8-pin connectors. I guess they'd rather you just
buy their chassis with the correct P/S.

connector when you built it. So you have half of the 8-pin socket occupied
by the 4-pin?

the whole power supply thing is confusing
as you point out in your 1st line, the H8DCE requires
"an ATX 12V P/S"
meaning they say nothing about needing a 24 pin
and an 8 pin and a 4 pin, but that's somewhat
built into the "12V" ATX and EPS specs
start at www.wikipedia.org with: atx
at the bottom of the def, it shows the history of
the different power supply names (some 5 or 6 of
them) and a line on the basic general specs as well
as several useful external refs if you want a good
pdf file on the main recent ones. you'll note that
the ATX 12V line only mentions a 20 pin <grin>
i simply went to newegg, pulled up all of the power
supplies, saved it to my PC as an htm file and (off line)
decided i wanted a "12V" one with a single 120mm fan
and 24/8/4 connectors and went with CoolerMaster 550
http://www.newegg.com/Product/Produc...82E16817171009
it meets these specs:
EPS 12V V2.1 and ATX 12V V2.01
per SuperMicro on page 1-12 of the manual, the power
supply has to meet ATX 12V V1.1 or above and have
adequate power
too bad they don't mention the 24/8/4 connectors
on that page.

Now if the mbrd & P/S mfrs would be a bit more explicit, we'd know what to buy. I mean: SuperMicro just says ATX with the obviously non-ATX combo of 4-pin + 8-pin connectors.

So you have half of the 8-pin socket occupied by the 4-pin? |
Confused the hell outta me when I bought the damned thing too.
Pluging a disk drive connector into the motherboard took quite a
leap of faith.
