Can you provide the power rating, printed on the side of the PSU ? It
would look something like this. Some old supplies put the emphasis
on the 5V rail, and such a supply might not be optimal for this
application.
+3.3V @ 18A, +5V @ 25A, +12 @ 19A, -12V @ 0.8A, +5VSB @ 2A
Also, knowing the brand and model number of the supply, might make
it easier for someone to guess at the quality of the supply. The Pentium D 915
draws a maximum of 95W. At 90% Vcore conversion efficiency, that would be
about 12V @ 8.8A current draw. Allowing another 2.6A for hard drive, CD, and
fans, brings that up to 11.4 amps. When you get a Core2 Duo some
day, that will be 65W instead of 95W, and use less power.
The 20 pin connector on the PSU is fine. If you ever decide to plug in
a PCI Express video card, they can draw up to 4.35A or so, from the 12V
rail. THe motherboard fan headers add another 0.5A to that. That current
flows through the single pin on the 20 pin connector, and it is rated at
6 amps. Basically, unless you're using an SLI board, at this point in time,
a 20 pin connector is fine, even using a PCI Express video card. Of course,
if you put too powerful a PCI Express card in the system, it may be too much
load for your total 12V rail rating. (Whether this simplification remains
true, really depends on what developers do with the PCI Express x1 slots and
card types. The power for those slots will come through the single wire
as well.)
If the product description says "no fan or cooler", it is up to the customer
to buy one. Sometimes this is indicated by "retail" versus "OEM", where the
"retail" product comes with a cooler, while the "OEM" doesn't. It pays to
read the advertising copy, to be sure what you're getting.
My personal preference for coolers, is to find something that is easy to
mount, and doesn't stress the motherboard. Every one has different tastes.
Some people don't like the "push pin" design of the current generation of
Intel provided coolers.
The P965 Northbridge, has a TDP of 19W. It would be nice if the airflow from the
CPU cooler, happened to push a gentle breeze over the Intel provided heatsink.
I doubt in your application, the P965 will be drawing the TDP value, but it
may some day. For example, not plugging in a PCI Express video card, should
provide a power saving. And only using one DIMM, means one memory channel can
be shut down
For the memory, it's plug and pray. If the Intel board has a recent BIOS
installed, it probably won't be a problem. I'd expect more trouble from
an enthusiast memory.
If you were looking for low power, the Conroe-L is only 35W. This is a
single core processor. Only issue would be, whether the motherboard
you are buying, has a recent enough BIOS in it, to work out of the box.
If you had access to an older LGA775 processor, you could flash upgrade,
then plug in this Celeron Conroe-L. Even a wimpy power supply could run
one of these.
