Power supply recommendations for 915G chipset

[Guest]

Archived from groups: comp.sys.ibm.pc.hardware.chips (More info?)

As George Macdonald was nice enough to point out in his reply to to my
post above titled "DDR2 memory--must it be bought in pairs", the new
intel 9xx chipsets require a slightly different power supply (ATX12V
V2.0) with a 24-pin mobo connector, as opposed to the usual 20-pin. I
was just wondering who makes good (and very quiet) power supplies with
teh 24-pin connector and where can I get one? I bought most of the
components for my new system from newegg, but they don't seem to have
standalone power supplies. Help would be appreciated--thanks.

I hope you saw my correction to the post in the previous thread - you *can*
use a ATX12V V1.2/3 with a 20-pin connector in the 24-pin socket - if not:
http://www.antec.com/pdf/article/ATX12v2.html. That may be somewhat
unsatisfying as a solution but unless you have a high PCI-Express load it
won't be a problem; the increased CPU load which could necessitate the
ATX12V V2.0 likely won't be seen for a while yet.

Yes NewEgg does sell power supplies but you'll note that, so far, many of
the ATX12V V2.0 ones seem to be at the top end of the wattage scale and
there are very few cases which come with one as part of the kit... also
NewEgg doesn't seem to have realized the need to differentiate the
different connectors in their product descriptions. The new Antec NeoPower
models seem to me like a good idea, with the detachable, socketed cables
but it's a 480W and err, kinda expensive.

For a run-down on all the different power supply types, there is good info
at http://www.power-on.com/ and they also have adaptors for just about any
combo - note the pop-ups of pinouts for the connectors on the details page
for each P/S.

I've seen self printed posters from local antec distributor that shows
them using a 20pin on a 9xx board, just plug it in and ignore the
empty holes ppPp

While I've never tried a 9xx board, according to my friends and my own
experiments, most boards with the 4pin ATX12V connector usually only
draw a marginal amount of power through it.

That's the way my Tyan S2875S works. The ATX connector is keyed and
only fits in the right holes in the EPS12V connector. The 4-pin ATX
connector fits in the right holes on the 8-pin EPS12V socket and the 4-
pin connector fits a drive cable. The latter kinda threw me, but...

For a picture of the setup, see (bottom of page 31):

If you want to get a top quality PS, you can get a PC Power and
Cooling Turbo-Cool 510 Express. PC Power and Cooling power supplies
are much higher quality than Taiwan brands like Antec, but they are
also much more expensive. Unfortunately, they don't make an Express
model in the quieter (and cheaper) Silencer product line. Here's a

I know it's bad form to followup to myself, but I just realized that
could be read wrongly. I meant marginal +12V power drawn through the
main ATX connector if there is a 4pin ATX12V connector.

I understood that. ...but was also a tad curious at how you reached this
conclusion. Do you have a clam-on current meter?

Oh, we had the leftover bridge from my other curiousity sating run on
power that I bullied my friend into making pPP

Basically, he wired those 4-pin connectors, 20 pin ATX connectors etc
so that we have all the 12v on one side and so forth. It makes it easy
to use the clamp on meter to measure the whole bunch of same voltage
wires as well as allowing us to measure the voltage drop (idea
courtesy of the good folks from S.E.B) across a 1 milli ohm current
sense resistor.
