backwards compatible power supply

the power supply fan is starting to go in one of my boxes -- in the
past using other PSs, I've removed the unit, taken it apart, and lubed
the fan, but that seems like a lot of bother.

at the moment, I'm using a fairly old motherboard (Asus P2B-S I think)
which I'll probably change out in a year or so. I gather that newer
motherboards have a different power connector. (presumably, however,
a new motherboard will fit into this case?)

can I find a nice quiet new PS that I'll be able to use with my new
motherboard next year? this one for instance

That one is not a bad choice, but you need an 8 pin or (4+4) pin CPU power
connector if you are looking to recycle your next power supply into a future
system. If you are sure that your mainboard is P2B-S and you want a power
supply for a future upgrade, I'd suggest the following:

just be aware that it only has four molex, so if you have more than four
total of (optical drive and hard drives combined) you might need to find
something different

Any new power supply you buy will work with your existing motherboard.
Your motherboard requires a 20-pin ATX connector. Most new power supplies
have a 24-pin connector, but the 4 end pins can be disconnected or just
hang over the edge not plugged into anything.

I would caution you from installing a new motherboard in your current case,
as the ventilation probably isn't enough for a P4 processor. Your case was
designed for a Slot 1 or P3. I just wouldn't reuse the case when you
upgrade next year.

Finally, I think you should just dump the whole system and buy something
newer. It doesn't have to be brand new or state-of-the-art. A slot 1
system is just so old now. You could buy a used P3 or P4 system on
Craigslist that would have 6x the processing power for around $200.

Until you get an all new machine, why not just replace the fan?

I've replaced dozens of them and it takes about 5 or 10 minutes.

Never had an luck with lubing them .

Any time I did(thick motor oil), it worked like a charm.

thanks all for the guidance.

this computer actually performs pretty nicely -- it's got a cute
little adapter I used to fit a Tualatin in it. it's not as fast as
the other box, a Pundit with a dual-core AMD -- but while it's not
really a speed demon, it's stable, and just fine for what I use it
for.

another issue is, on this box I mostly use OS/2 (with a little bit of
openSuse 10.3) which these days is quite picky about hardware -- and
so am I. I like SCSI drives (my personal preference, no need to hash
this over) so I'd have to spend on a PCI scsi board -- and while I
don't doubt that I could find a board with enough PCI slots for the
SCSI adaptor, the sound card I'd want to bring over, and the network
card I prefer -- anyway, it would be an expenditure of a fair amount
of money, probably $700, and except for the groaning fan I really have
no urgent need to upgrade. and, more importantly, don't have the time
to devote to getting a new box up & running.

hmm, I was thinking that this morning. I had an old PS lying around
and unscrewed it, just to have a look -- and I didn't see an way of
removing the connectors for the fan. the wires were soldered to a
little circuit board sticking out of the PS chassis & I found myself
wondering, & doubting, whether fans are sold attached to little
circuit boards.

& just now I took apart another old PS I have (a 320W) -- same thing,
only this time the "brains" seem to be in the fan's guts. I guess I
could see if I could dig up my old soldering iron, tho I was never
very expert.

Oh heck, don't bother with the soldering iron...I just cut the wires and
splice.
It works fine and who cares what it looks like...just as long as the wires
are positioned not to
touch the fan blades it will be fine.
