down-clocked 7600GT in a Silverstone LC-19 mATX case?

[R3MF]

hey-ho peeps, got a question for you.

> a LC-19 case comes with a 120W PSU
> an AM2 low power X2 3800+ uses 35W
> an nForce 570 Ultra chipset will consume about 30W
> two GB?s of DDR2 will consume about 15W
> a Seagate 320GB 7200.10 will want about 10W
> to recap, thats 90W used out of 120W available
> a 7600GT running at 560/700MHz is quoted at 67W under PEAK load
> therefore i am 37W overbudget

my question is: if i down-clocked a 7600GT to 500/500MHz would i be able to bring that power consumption down to 30W, and therefore be within budget so to speak?

power consumption appears to grow exponentially when chips are clocked very near to their maximum, so i don?t think it is beyond the bounds of possibility that i could get away with the above hardware spec, but i just don?t know.

there is a very nice albatron 7600GT board that is passively cooled and would be just ace in an LC-19 sat alongside a dual-core A64!

all assistance much appreciated

just found this:
http://www.xbitlabs.com/articles/video/display/gpu-consumption2006_5.html
given that a 7800GT never peaks more than 56W i remain that hopeful that a down-clocked 7600GT will not peak more than 30W...........

and this:
http://www.vr-zone.com/?i=3335&s=8
vr-zone list the 7600GT as consuming 51W Peak at 560/700

this is the graphics card:

that massive rear heatpipe/sink will sit just under the LC-19 venting, perfect.

so, how about it?

Dont think its going to work to be honest, my sli Matx case is running a x2 4200+ 2 x 7600gs and 4gb ddr with dvd and 200gb drive on 240 watt psu. the problem is that you have other things such as usb which will draw power.

I think you should consider a lower rpm hard drive ( i think their is a low power 540 available) and perhaps an ati chipset which reportedly use less power than the nvidia chipset. As for the graphics card a downclocked 7600 is a good idea, the gddr3 uses less power than the 7600gs ddr2. I would go further and use nibtor (sp) to lower default clock speed and drop the vcore down to 1.2 from 1.3/1.4 that the gt runs at.

cheers for the reply.

ATI is a negative, i want this as a linux box and their drivers suck.

what is this nibtor thing, and what do you use it on?

cheers.
