I've decided to finally get rid of my crap PC Chip's motherboard. What's a
good choice for a new one that will support an Athlon XP chip and will work
well with a powercolor 9800 pro?

I have an MSI K7N2 Delta ILSR, which has all the latest features you could
want and it runs great with my Radeon 9800 Pro.

Hi,
I can highly recommend the ABIT NF7-S to you. It's now a legendary mobo,
and also has AWESOME onboard audio system called Soundstorm. I won't go
into to much detail, but suffice is to say that Soundstorm is the *best*
gamers onboard audio solution around, it can do dolby-digital encoding
(ENCODING, not decoding) so that your games will be played back in
Dolby-Digital 5:1 if you have the right Amp+ Speakers.

If onboard audio (sata+ firewire) is not important to you, then grab an ABIT
NF7. . .

The 9800 rocks!

Mmm, I find ASUS a good branch. Make good motherboards, wich runs
stabile and tends to overclock well even!

:-)

They got AGP 8x motherboards in both Intel chipset, Sis Chipsets (
cheaper and still very good ) and I also believe VIA chipsets. So
choice enough!

Wich one you need... well..what do you want on your "pizza" ..heheh...
there is so much choice on what to get, onboard sound, onboard gigabit
network. But there are ofcourse also simple pure "pizzas" with not
much extra features and definitly cheap.

Go Asus...or MSI... or Chaintech... just one of the bigger names in
the computerworld!

If you are truly on budget, ASrock.. the budgetline of Asus!

Just don't get an Antec ps with that, they've told me they're

Which Antec PSU? I saw someone post that they were told not to use an
Antec 380w that comes in the Sonata case, but somehow I think this
information is bogus. I use a 400w Antec Smartpower with a 9800pro
fine. I've seen people post with Sonmata cases that have no problems
with a 9800pro. Or is it just this make of the 9800pro? If that's the
case then I would keep far away from them.

I have seen posts similar to that...I have 2 systems..one is running a
Chenming 601 AE case with an Enermax 465 with 9600XT..no grief..second is a
Chieftec with an Enermax 465 with a MSI 4200VTD8X-128..rock solid also. So I
would go out on a limb and recommend an empty tower with an Enermax PSU

I think there are Antecs, and there are Antecs. A case I bought last year
had a 400 W Antec power supply that failed within six months. Frankly it
looked cheap. I currently have an 550 W Antec True Power supply and it's
sweet. Quiet, cool and not a hiccup.

And exactly what did they say? Were they talking about just the
Powercolor version or all 9800pro vid cards? And I've seen this info
before, Antech did'nt say all Antec power supplies, they said the
380w model that comes in the Sonata case. You made it sound like all
Antec psu's which is complete BS.

Oh, and now you decide to come out with the truth instead of a
misleading statement.

You said, "Just don't get an Antec ps with that, they've told me
they're "incompatible".". That is a damaging statement and you should
be more preecise in what you say. We still don't know if they are
talking about the Powercolor version of the 9800pro or all versions.
They may simply have said that because the they don't consider the
380w version of the Truepower poweful enough for the 9800pro. But, I
know there are many people with Sonata cases (has 380w Truepower) and
a 9800pro and htey have no problems. This subject needs better
clarification.

The only mod I know of is that it has one fan instead of two, and they
may have beefed up the internal heatsink but not sure about that. I
highly doubt the amp ratings are changed at all, which is what would
determine if it is enough PSU for the 9800pro.

Anything can fail so that doesn't really say anything. I have a 400w
Smartpower Antec (that's their cheaper line) that came in an Antec
case that I bought and it has been rock solid for two years now. And
that's running a 9800pro right now. I also have a Zalman 400w that
cost me $150.00 CAD and is being used in a less powerful system
because I found the 12v rail was better on the Antec than the Zalman.
Zalman have since beefed up the 12v rail on the new version of the
same PSU. Old model =15amps on the 12v rail, new model has 18amps.

Follow the bouncing ball! I'm the one saying that it applies ONLY to
the 380w in the Sonata case, everyone else around here keeps saying
"well, it works fine with my 420w True Power". Who cares if it works
with your other Antec, I'm talking only about the 380w TP.

No you didn't! You made a blanket statement of Antec PSU's. Now I see
in a later post you have said 380w Truepower.

I asked them if the PS in the Sonata could handle the demands of the
9800Pro, they replied "We could not guarantee the power supply to work
with an ATI 9800 Pro for we have some compatibility issues with it."

They also said it is perfectly within specs that their power supply
deviate +/- 10% on the +12v rails, so I don't exactly trust everything
they tell me (my deviate +/- 7%, even though their website says it
will remain at +/- 3%).

I have and Antec Sonata with a 380 TP and a 9700 Pro. Never had any kind of
problem, despite the fact that the case is jammed with drives and fans.

Fact is, I've never heard any suggestion of any problem with this psu or
compatibility issues with any particular component -- outside this thread,
of course.

I'm not questioning anyone's credibility, but I would appreciate a link to
any forum or website where any sort of confirmation of this alleged problem
can be found. Or even something specific on the type of problem or symptoms
under discussion.

Otherwise, I'm inclined to chalk the whole thing up to miscommunication.

97Pro's have been put in Shuttle cases and they have little more than
200w psu's.

But in terms of m/b's, the intel's just seem to be less of a problem.

OK, then what did they change that makes it incompatible with a
9800pro? Funny thing is we have a poster in this thread that says he
has this PSU with a 9700pro and it runs fine. I think my assumption is
correct, even though it's not really an assumption at all because I
have read reviews of the Sonata case and they told the reader the
specs of the PSU.

I have no idea. I don't work for Antec and I have better things to do than
run out and get a Sonata and boxed 380 and take them apart and see what the
differences are.

Personally I don't care whether the Sonata does or does not have a problem
with the 9800. My point is that Antec saying that the Sonata has a problem
does not, regardles of its validity, automatically imply that the boxed 380
has the same problem.

OK, thx. I saw someone post in another group that 13amps on the 12v
rail should be adequate for today's machines. I bought a Zalman 400w
not long ago and it is 15amps on the 12v rail. Zalman decided that
wasn't beefy enough and they have a new version of the same 400w PSU
but with 18amps on the 12v rail. Decent and quiet PSU but it's not
exactly cheap either.

Go have a look:

12v is +/- 3% unless I'm misreading it.

And one Antec 380S isn't the same as another 380S. I bought two, and
the power supplies are actually different (one has extra connectors
for an SATA drive and looks different too).

400w Antec and never had a problem again. Maybe I just got a duff one
though. Which model you talking about that has 33A on the 12v rail?
I'm looking at the specs on the 465 right now and it is 18amps on the
12v rail.

Will do. I just sent them an email asking for clarification.

What brand of PSU? Not all 300W PSU's are created equal.

I have 2 465FM's........but I see what you are saying...looking at the specs
on the website and the supposed"specs" stamped on the side of my newer
one..they differ...hmmm..but I will say this....when I put in my first one
on my power hungry MSI Kt400 board..what a difference it made...my CPU fan
used to slow down on reboot or games launching till I switched it up..but it
is just another of those preference things that tends to happen.
http://www.enermax.com.tw/product-01.htm

maybe I have misread..or looked in the wrong spot..but these are the 2 I
have...so which is right...the top or bottom chart?..and remember the one
spot says (250W model)..and that says greater than or equal too..for 250
watt

anyways the link is not to my exact model....if you go down to the Fan
Monitor Series i have 2 of the EG465P-VE FM PSU's....the link I pasted is
just generic...sorry no help for it.

Someone posted this in the Abit group.

ATX 2.1 specs are as follows:
-5 10%
-12 10%
+5 5%
+12 5%
+3.3 4%
+5vsb 5%

OK, I see where it says 33amps now. I wonder how accurate those
numbers are though. As I said, I had problems with the 365P and it
shows 26amps. How come my Zalman with only 15amps doesn't give me any
issues but the Enermax did?

maybe it was just one of the bad ones...it does happen from time to time..I
started getting random reboots on my other system after putting my old
Ti4200 in it..so I went and bought the 2nd Enermax and problem solved.

That's what Antec say their PSU is, not what the ATX spec says it needs to
be.

http://www.formfactors.org/developer/specs/ATX12V_1_3dg.pdf

+12VDC ą5% (1)

+3.3VDC ą5% (2)
-12VDC ą10%

(1) At +12 VDC peak loading, regulation at the +12 VDC output can go to ą

(2) Voltage tolerance is required at main connector and S-ATA connector (if

So thats nice and clear/consistent.

Notice that in the change from 1.3 to 2.0 of the PSU design guide, a second
12V rail has been introduced with tighter regulation. The ATX Spec 2.2
references the ATX PSU design guide 2.0, but only specifies one of these
rails.

Also, it seems that according to the PSU design guide, 10% is ok when you're
near your limit. Seems to me that a given tolerance is a given tolerance,
not sure why it should change when fully loaded - the same limits should
apply.

Lets assume everything useful (+3.3V, +5V, +12V, +5VSB) at ą5% and the
negative ones (5V, 12V) at ą 10% (since they're generally not used and
therefore unloaded)

I guess it may have been bad, but read the below text. This reviewer
had the exact same problem with the same Enermax PSU. My vid card at
the time was an R8500 too, as his was. I never did get my Enermax
replaced. Just went out and bought an Antec and let the Enermax
collect dust in the basement. I have two PC's here and one is using
400w Antec and my designed to be quiet PC is using a 400w Zalman.
Both have stable voltages but the Antec is a bit better than the
Zalman on the +12v line. The Enermax 365 cost me $65.00 CAD, the
Zalman $150.00 CAD, I think you get what you pay for. Enermax may have
improved a lot since 2 years ago but I take their 33amps on the +12v
line with a grain of salt. That's my take on it anyway.

http://www.gamingin3d.com/articles/ps_roundup/main.shtml
Jeez, Louise! What's with the Enermax powersupplies? There's a hefty
drop on the 12V lines under load, with respective increases on the 5V
lines. They both pass within +/- 10% limit, both not my preferred
"high-quality" +/- %5 limit.

In comparison, the Zalman/Nexus duo barely break a sweat under load.
The Zalman has a SLIGHTLY better 12V line... but the difference isn't
worth writing home about. Both of them have all their lines fall
within +/- 5% of the respective line's spec, so stability issues due
to under or over voltage should be non-existent.

(side note: while the Enermax powersupplies may seem a bit weak in
comparison, they're still better than the average generic powersupply.
I used the same test on an old generic 250W I had lying around, and
the thing dipped below 10.7V on the 12V line! That's just
unacceptable...)

Another note on the Enermax powersupplies: while it seems the
newer-yet-lower-end 365 model beats down the discontinued 451 in every
conceivable way, there is a problem with it... or at least the one I
have on hand. The problem is with certain video cards. For example, if
I use my Radeon 8500 with the 365, the system will crash whenever I
try to start a game. Annoying to say the least.

You think that's the end of the Enermax story? I wish. I've been
trying to get it replaced (since it has a 2 year warranty...
supposedly), but the retailer I got it from said they only covered it
for the first year. The second year is through Enermax... Yah. Right.
Their website says to either contact the retailer (which is obviously
not an option), or if that fails, a "branch office or agent in your
area". Well, I tried all those offices and agents. Everyone of them
gave me the run-around. They would either tell me to call someone
else, that the drives are only covered for 1 year (it says 24 months
right on the box... last time I checked, that equals 2 years), or they
would tell me "we don't deal with end users". Now I'm stuck with a
problematic $50 powersupply that's under warranty, but no one will
warranty it.

p.s. Dino, have a look at that article and look at the pics of the
insides of the Zalman compared to the Enermax.
