Default Power consumption on 9700

Has anyone measured the real power consumption (Watts) of the ATI 9700 card?
The reason for my question is that I'm currently running a ATI AIW 8500DV card on my Shuttle SS51G barebone system, and I've been able to reach a maximum of 130 Watts (P4 2.4GHz/533 and 0.5 Gb 333Mhz DDR mem) during gameplay, and I'm wondering if there is a slight possibility to successfully use a 9700 card on my Shuttle (200 Watts PSU)?
Btw, I'm reaching approx. 92 Watts during normal desktop operations.

I'm NOT interested to know theoretical measurements or the maximum power output as specified in the AGP specification. I would like a nice use case e.g. the maximum/median power consumption measured when playing a demanding game such as Doom 3 "beta".

Can anyone help me with this?

The problem is not so much the total power, as the power coming off the 3.3 V and 5 V rails. Each rail has its own separate power rating, which should be listed on a sticker on the side of your box.

I briefly had my 9700 in my old PII 350 system with a 250 W generic PSU. It would lock up if I tried to run all the 3DMark tests as a batch, although I could run them each individually.

I'm guessing it's hard to measure the 9700's power consumption directly, because it takes power from both the AGP slot and its separate power connector.

Hard data seems HARD to come by .

I can't find anything anywhere, and have been GUESSING comsumption at 30-50W. I am trying to find out wether the card takes it from the 0.8V AGP port, the 5V line on the plug, or the 12V line on the plu, or the most likely a bit from everywhere.

ANYONE who can find out I'd be happy. E-mails to ATI lead to no response. I'll be damned if I start dropping hair wires to figure it all out...

measurements of power consumption of AGP cards:
http://www.tecchannel.de/hardware/907/51.html
testing method: http://www.tecchannel.de/hardware/908/5.html
(so the 54W for the R9700 pro are probably a bit too high if I understand their method right).

mczak
btw agp limit would be around 30W (6.6A on the 3.3V supply line, 2A on the 5.0V supply line) maybe higher (not sure if the 12V supply line of the agp connector (1A) is ever used) - but since the R9700pro has an additional power connector, it can draw whatever it wants (well, almost). If it doesn't work with the 200W PSU, you could try a non-pro R9700 (should use around 15% or so less power) and/or underclock the graphic card/cpu.

I'll be damned. I did not search for Shuttle in the forums. Sorry. I'll check it out immediately.


mczak:
Thank you for your useful information. However, 54W does not seem to be impossible. I'm also afraid that the power peaks might be too much for my tiny PSU.

macleod199:
It's not that hard to measure it. The simplest way is to use an external meter and connect it between the PSU and the electric outlet and then subtract the power consumption used in normal operation mode from the consumption used during heavy load. Still worried though that you had problems with your 250W PSU. Did your system freeze only in 3DMark or did it freeze during gameplay as well?


Hmm, this was a though one. Think I'll have to check out the other Shuttle'ers experience with the 9700 card. Feels a bit awkward to buy such an expensive card if it doesn't work. On the other hand I'll be stuck with a GF4 Ti4600 card

Just a small update:

I bought the 9700 card (non-PRO) and it work fine on my SS51G shuttle.
I performed the same test again and reached a peak of 148 Watts, but normally it consumed about 141 Watts during heavy load. Notice that I ran a rather exhaustive test including both gfx card, CD-ROM and HD at the same time.
My system seem to be really stable. I have not encountered any problems so far.
Btw, the card reached 12651 points in 3DMark2001 SE (1024x768, 32 bpp, no fsaa). Seems ok.

Angry minimum 300 watt psu for 9500/9700

says that on a card that came with with my retail 9700

I think the actual figure is 8.19 terrawatts.
