I need to get a new power supply and quiet operation is an important
factor. I am considering the Zalman Noiseless 400 watt ATX
(ZM400A-APF) which has received very good reviews.
Is 400 watts sufficient for the following system -
Abit AI7
P4C 2.6Ghz
4 - 512 meg PC3500 ddr (2 Gig total)
4 hard drives (2 Samsung 160 gig SATA, 1 WD ATA100 160 Gig, 1 WD
ATA100 80 gig)
1 cdr
1 dvd writer
1 Wacom graphics tablet
Matrox 450 AGP
no PCI cards
May try overclocking but I need to change cpu heat sink. Using Intel
now. It runs at 225 FSB (1:1) but was experiencing slowdowns and
freezing while running disk keeper and trying to do anything else.
At 212 FSB I didn't notice anything unusual. I haven't played with
different settings much since system was just put together. Abits
Guru utility was saying that my cpu temp was 170 F (at 225 FSB), so I
set everything to default (non - overclocked) settings and the cpu
temp. came down to 120 F. I wonder if this temp. utility is accurate?

I would think that 400 watts should be good unless you really start to add
fans and hard drives and such and a new nVidia or ATI based video card.
then you might need to consider something higher but probably not.
if you were really running at 170F (almost 77C) then you were in the danger
area. that CPU may have even been clocking itself back to attempt to cool
things down. you have some serious cooling issues either in terms of the
heat sink performance or the heat buildup in the case environment. you can
run the system with the cover off and a fan blowing across the case to see
if the heat buildup is related to poor case airflow. if temperatures drop
significantly, then you know you have a case airflow problem.
there is no reason that the Abit uGuru utility could not be trusted to give
proper readings. however, there is a track record of Abit 875 and 865 based
boards running on the warm side as far as readings go, sometimes as much as
10 degrees C in some folks eyes.

I have that PSU and run it with a P4 2.66 cpu, ATI 98000pro vid card,
two HDD's, cdrw, DVD drive, etc. with no problems.The Zalman PSU is
not noisless as they claim, it is quieter than average but certainly
not noisless. In hindsight I should have just stuck with my Antec
Smartpower 400w as that only has one fan too and it is barely louder
than the Zalman. The Zalman fan inside the PSU runs at low rpm's until
it detects too much heat, then it speeds up, my Antec Smartpower does
the same thing, the Zalman compensates with heavy duty heatsinks
though.<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: Power supply size |

Thanks for answering my post. It motivated me to open the PC up and
replace the Intel thermal pad with some artic silver II. I was going
to do that when I replaced the Intel heat sink. The intel pad was only
making contact with about 1/2 of the cpu. I took it off and will now
do some new overclock testing. I hope that didn't damage the cpu. It
was running high for about 30 to 60 min. I do have a case temp. alarm
installed and that didn't go off so I suspected it was just a cpu
issue.

good luck with that... I doubt you harmed the CPU as Intel P4 CPU's will
just downclock in the event of an overheat. I'm sure that it would not be a
good thing to have happen with any regularity though.

If you check the specs of the PSU you have:
<a style='text-decoration: underline;' href="http://www.directron.com/zm400a.html" target="_blank">http://www.directron.com/zm400a.html</a>
The +12V has a 15A rating, which is probably marginal for your setup. You
have 4 hard drives and two ATAPI devices, assuming 1.5A per device, that's
already 9A right there, leaving only 6A for your CPU and your case and
processor fans (about 0.25A a piece). So I would recommend getting a PSU
with a more powerful 12V rail esp. if you want to overclock. I would
recommend the Fortron FSP530-60GNA selling for $72 shipped at Newegg:

How is the noise of the Fortron unit? How about the Thermaltake 480?
OUt of these two which is quieter but also would have enough power?

Very quiet according to people at the overclockers.com forum. The product

indicates that it has "fan w/ noise killer" which probably means variable
speed fan.

As it's been mentioned be careful with fans and PSU's that claim to be
silent/quiet (Vantec stealth fans are a prime example) Look for real
world reviews if noise is your primary concern. Vantec stealth fans
are rated at something like 20-21dba, however reading various reviews
it's clear that this "rating" is a LIE and should not be trusted. I
personally picked up an Aspire 520W PSU from newegg. Has a variable
fan control knob on the back for great fine tuning of the noise. I
have it about 3/4 the way up and you can barely hear it.
Also if you take the thermal pad off be sure to clean the cpu and the
heatsink off to get rid of any residue, and use Arctic Silver 5 if you
can get it (check AS's website for all the info about removing pads
and etc)

Thanks for the response. I read the reviews by owners and decided to
order the 530W Fortron.

I have a Globalwin SAF Sapphire and I am very pleased with it. Its
*extremely* quiet if you set it to LOW fan speed (you have to put your ear
next to it to actually hear it - from 3 feet away, its silent.) In AUTO
mode, its more audible, so I leave in on LOW. I don't really see why you
would want it on MEDIUM or AUTO. What's the point, when its perfectly happy
running on LOW all the time?
Mine is rated at 19dBA. The new "Onxy" model is 18dBA. That really is
quiet!
The good thing about the Globalwins though is the excellent voltage
stability and really strong 12v rails. They aren't cheap, but they are
really good PSUs
Chip.
