Plugging a drive power connector into a video card, any card, is
ugly...ugly... ugly.

I thought the same when I had to plug a drive connector into my
*motherboard*, since I "only" had an ATX12V supply.
 
Well, it doesn't make too much of a difference here, the power all
comes from the same place regardless of whether it's going through an
extra 4 pins on the main power header or a separate connector.


Agreed. It doesn't really make a difference electrically speaking
where it gets the power from (so long as it can get a good, clean and
steady supply), but the simple idea of plugging a hard drive connector
into a card just seems somehow wrong.

Actually it does make a difference. The smaller the loop (one can argue
the drive supplies are a short loop) the better the supply and lower
EMI. Grounds and power in long loops isn't generally what one tries
to do. Long wires also increase the impedance of the supply. Since it's
not possible ot model all combinations of supplies, cables, and do-dads
hanging off the cables, I'd say it was a rather weak situation.

In poking around for info I came across this:

I dunno what's worse... using a drive connector or defining a new
connector... which nobody has yet?? I guess people who need >75watts for
their video card can just pony up the $$ for a new PS to match it.:-)

The really dumb one on all this is AMD's ATXGES, with a completely
different arrangement of pins.

It's pretty much a dead standard since the Opteron came out. Very few
boards ever used the ATXGES connectors.

If you need basic to med complexity webpages at affordable rates, email me :)
Standard HTML, SHTML, MySQL + PHP or ASP, Javascript.
If you really want, FrontPage & DreamWeaver too.
But keep in mind you pay extra bandwidth for their bloated code
