I thought the same when I had to plug a drive connector into my
*motherboard*, since I "only" had an ATX12V supply.

Am I the only one that doesn't like having a video chipset that
consumes so much power it needs a drive connector to power it? If
nothing else that is yet another extremely unreliable fan in the
system just waiting to fail the day after the (1 year) warranty
expires. It's not even like you can buy easily buy replacement fans
for most of these cards since they're all customer jobs.

Even the PCI-Express mbrds have the extra power but of course it's
integrated into the 24-pin power header on the mbrd - something else to
worry about in futu is the power supply really putting out more or did
they just add a 20-24-pin adapter somewhere?

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
