4 pin vs 8 pin EATX connect
Fitz
ASUS Maximus II Formula motherboard. The power supply has a 4 pin EATX12V
connector. The motherboard has an 8 pin connector, of which 4 are
capped. The
motherboard manual says:
"Make sure to remove the cap on the EATX12V connector before connecting an
8 pin EPS +12V power plug."
"Use only an 8-pin EPS 12V power plug for the EATX12V connector"
So, the motherboard has 4 of the 8 pins capped, so that a 4 pin
connector will
fit, but then specifies to only use an 8 pin connector.
Questions:
Will the 4 pin work?
If not, can I get an adapter from 4 to 8 pin (maybe from Corsair)?
Or am I SOL and need to buy a new PS?

Yes, providing you aren't drawing an excessive amount of
power. Some might be limited to about 6A per lead so that's
12A from a 4 pin (2 power and 2 return/ground leads)
connector, and supposing about 92% efficiency from the
motherboard that means it would support 12V*12A*.92 = 132W
processor.

It wouldn't make a difference if you used the adapter, you'd
still be pulling the same current through 4 pins. I take
that back, it might be possible to get an adapter for
another 12V plug on the PSU too so there are more than two
power leads.

Look up the wattage rating of your intended CPU. If you are
going to overclock it you will have to account for that
addt'l power consumption too.

recent unit.
The manual claims that it has *both* 4 pin and 8 pin 12V connectors. Is
there more than one model of the HX620? (The answer may be yes.)

Yes, the warning is poorly worded . It to prevent somneone from mistakenly
connecting a PCI-e cable to the connector.

There are 3 cables on the power supply that are permanent (non-modular)-
the 24 pin connector, the 4 pin 12V and the 8 PIN EPS 12V.
Because neatness counts, when I assembled the existing system, I routed the
unused 8 pin connector to the back of the motherboard tray and neatly tie
wrapped it out of the way, out of sight (and apparently out of mind). When I
took off the "other" case side panel, there it was, waiting to be used.
Thanks for the help- on to building the upgrade!
