Old hardware power consumption!?

post #1 of 7
Thread Starter 
Hey guys,

I have this really old Dell Dimension 8100. It has an honest 250W Delta power supply with excellent component selection and good cooling.

I'm trying to upgrade it a little bit...just for the hell of it. With Ubuntu or Xubuntu, I should be able to get very good results. I'm hoping I can get a fully functional PC for less than the price of buying one.

However, I don't have a clue about what kind of power consumption this thing has because the hardware is so old. Here's the proposed system after upgrades. Mostly used eBay stuff.

Processor: Pentium 4 1.3Ghz- Socket *423*
RAM: 4x 256MB RDRAM
Video Card: NVidia 6600GT
Hard Drive: Momentus XT
DVD Drives: 2x DVD Burners
Sound Card
USB Card
Firewire Card

Does anyone have a clue about what the socket 423 Pentium 4s consume? Not to be confused with socket 478. This is a Willamette core processor.

Right now, there is a FX5500 video card installed. Stock card was Nvidia MX440. Currently 2x RIMMs of RAM in there. 2x 7200RPM hard drives.

The 6600GT takes external power. Is 250W too little?

Thanks.

Check if this is really the CPU you own.
According to that its TDP is of ~50W.

the 6600GT should be about 75W. I think those 250W will be sufficent for it.

edit: Make that 50W for the 6600GT

Yes that is the CPU. It's 180nm which I thought would mean it wouldn't be too efficient. The TDP isn't the power consumption though...but it seems that the actual power consumption is usually a bit under the TDP. So even being reasonable with the numbers, it seems that the consumption will probably be around 150-200W. I could be wrong.

Is that enough leeway for an 8 year old power supply?

The PSU has taken it so far, it could endure a few more years, but can also die in a few weeks or months. I don't think there is a way to know with some accuracy how much time a PSU will still live. Keep it rolling with this one, but get a new one to have in case of this one fails on you to replace ASAP

Right. Well the thing is. This PSU has a 16-pin CPU power connection, which I'm sure I could modify from a more modern CPU..but even then, the power distribution is much different than a regular P4. These are more Pentium IIIs than Pentium 4s.

But I just remembered, I have a Dell Optiplex that I fixed up that I keep in my living room. 250W Seasonic supply. 2.8Ghz Northwood, GeForce 6200, 2GB DDR, 7200RPM Drive. Works well. The 6200 apparently has power consumption very similar to the 6600GT..somehow. Same core I guess.

I'd imagine most of the draw of the CPU will be from the 5v rail since it lacks a 20-pin ATX power connector. To be honest any half decent 300W unit will easily power that.

Well I looked around a bit. I think the power consumption should be under 200W at load. Around 120W idle. I think 250W should be enough. I'll pretty much never load it.
