New case power connections

[Guest]

Archived from groups: alt.comp.hardware.pc-homebuilt (More info?)

I'm just getting caught up with the various new hardware standards that
have come online in the last 2 years, and I have two questions:

1) Why the separate 4-pin power connection on the mb in addition to the
24-pin connector?

2) The case (Antec SLK2650-BQE) also has a 6-pin power connector labeled
PCI-E. I'm not using any PCI-E cards at the moment (the mb does have the
slots), and I don't see anywhere on the mb (ECS-A939) for this plug. Is
this a connector that some mb's use, or does it plug into a PCI-E card
itself? I don't think that is likely, but what do I know at this point...

Yes, some cards use 80W of power, which is a lot of juice for the PCI-E
connector to supply.

Even though you think"it's not likely", that's exactly where that connector
is supposed to go.
Some newer high-end gfx cards have power requirements way over what can be
delivered throuhg the motherboard...

If you mean the square one, that's for the cpu.

which is specific to the intel p4s

Not necessarily. I've had to use it to get AMD Athlon cpu machines to
start up. Not sure if Semprons require it or current crop of Athlon
64s.

Thank for the replies. I've gleaned:

Some cpu's need this, some don't.

Since this connector *does* go into a PCI-E card (makes sense that it
would be the graphics cards, SLI and all considered...), I would suppose
that the extra 4 pins on the main motherboard power connector is
primarily to power the other PCI-E (4x, 1x) slots.

Anywho, this clears up a few things, like I will need a new case (or at
least a new PS) when I get around to upgrading my own system. I had
these questions because of a system I put together for someone else (up
and running since yesterday). Thanks again.

A common connector used on most dual systems, they need more power at
startup, use a 450w - 480w PSU where these fittings are seen.

If it has one use it, BUT use a seperate power rail from the PSU to
that connector only, NO fans or drives etc.

Someone mentioned Vid cards that also have the extra molex connector,
similar deal there that's required for more power but used only for a
particular vid card's GPU power requirements and is a different reason
than for one used on a m/b.
