Need power supply min. requirement for rad.7500

Hello all,

I need the minimum requirement for the ati radeon 7500 (QW model, i.e. the
small one i think, not a mobile one) on AGP. It's to try to fix a problem
in a computer i cannot locate but wich seems to have appeared right after
the plug-ins of that card (on an old Abit BX6 mobo).

I know that "somewhere" in the depth of the cave of the ati site there is
such information but i've been unable to find it since friday !

Is someone from here can help me out ?

The current P.S. is 250w (ATX of course).

400W ?!

Ok, so, do you know where i can get those basics requirements that way
i'll be able to know exactly how much amp. i need in +12V, etc... ?

I don't want to buy an hyper high PSU for nothing.

For a _RADEON_ 7500? I think you are confusing ATI and nvidia. A Radeon
7500 is about 6 generations old and by modern standards has minuscule power
consumption.

A decent 250 watt power supply should be plenty for it unless there's
something the OP is not telling us.

Nothing special here. I just have 2 HDD SCSI (IBM 4.5 & 9 GB), a DC390U2W
card, a SCSI CDROM. USB mouse. PS2 keyboard. Celeron400. All 4 ram bank
are used up (327MB)... And it works perfectly with an old UTNT2 but when i
plug in the radeon 7500 it goes on reboot after reboot by itself,
sometimes after several seconds, sometimes it doesnt't even bypass the
complete bios check.

I would then doubt that 250W ratting. Get an Antec 300W and you will be
fine.
 
I think that ATI may not list the PSU requirements because they don't amount
to much. According to:

http://www.jscustompcs.com/power_supply/

the card needs less than 30W.

Assuming that all the hardware is actually working, all that I can suggest
is to make sure that all of the nVidia driver components are gone before
you install the Radeon. Driver Cleaner (http://www.drivercleaner.net/ )
might help.


Address scrambled. Replace nkbob with bobkn.

There is a good chance you bumped a ram card while installing the video
card. My bh6 is touchy that way and the fix is to reinstall the ram. I
suggest before you change any hardware that you remove the ram and then
reinstall one stick. If it works, reinstall the rest of the ram.

The RAM is ok as i'm currently using that board with the UTNT2 back in.

But that reminds me of a little change i did to the settings of
the BIOS: i put the PCI latency to 32 (witch was set to 64 before). That
worked perfectly for the rest of the hardware, but i don't know for the
radeon 7500.

At how much latency this card is supposed to work in the bus ?
I've tried to find that information but haven't succeeded.

Thanks for that address !

The system was a bit tight at 250W as, according to it, i needed 258W
(235W when using just the components left in to search after the problem),
but that should be working at least when not doing any 3D, as the result
given is a "peak" value.
the card needs less than 30W.

Thanks for the idea but there is no computer under WinXX here, only
Linux. And the driver system under Linux makes it not possible if not by
will to leave anything from an installation. ... And as the reboot even
happened before the OS started it is not related to it.
.... OR could it be possible that the video card is left in a kind of state
"i'm doing 3D" ? As the first time the reboot happened i was testing the
3D with a very simple utility usualy used under Linux to check if hardware
3D is correctly handled.
....
I've just tested it again and it didn't even reach the Linux boot.

But there is something i don't understand: if i'm quick enough before the
reboot to enter the motherboard BIOS... then i can stand inside a couple
of minutes before the reboot, when usually it just takes several seconds...

Is there a special settings to be used for this card or for ATI cards
generaly under the BIOS that i need /or/ that i must disable ?

I also have tried to check after the bios of the video card but haven't
found a way to do it. It doesn't display any information at the startup of
the computer (before the BIOS). And i haven't been able to find on the ATI
site for any kind of upgrade (that would allowed me to see the BIOS number
with the utility included).

Have you checked the temperature of the video card when it is crashing?
I had problems with this board crashing due to heat under 3D but you
could have a more serious overheating problem.

No, i didn't thought doing it. Thank you for the idea.
I'll try out.

Loading the default bios settings should set the PCI latency to the proper
level.

Well no, in fact after quite a bunch of research it will restore the
motherboard BIOS default which is almost always 32. No proper level, just
a default one.
Furthermore it seems that the ATI video cards are setting up their latency
by themselves, overwritting the MB BIOS.

So the problem does not come from that parameter.

I'll try to test it with a more powerfull PSU and on another MB, just in
the case of a simple incompatibility, but it seems that i'm heading
towards a material fault, i don't know a physical shock or something.

Thanks to everyone for the help.

Well, the websites of ATI, Nvidia and all the card manufacturer usually
don't list a requirement but a minimum recommend setup. Because even if
they list a 300W PSU as minimum it doesn't mean the card stops working
with a 250W PSU if the overall power consumption (which also depends on
the mainboard, the PSU, number and type of HDs, RAM, and much more)
isn't higher than what the PSU can deliver...
The current P.S. is 250w (ATX of course).

If you don't run a high end dual Opteron computer with this PSU it's
probably enough, the Radeon 7500 has a very low power consumption and
only draws a few watts. I once had a Radeon 7500 64MB in an old P3-600
which had a 210W PSU and it also ran fine.
