Does anyone have data on the efficiency 80 PLUS power supplied at very low power draws, ~20-30W? The SPR reviews of 80 PLUS PS' all seem to be above 40W, w/ efficiency dropping fairly rapidly as it approaches the lowest setting, and I'm wondering what they do as they get to ~20-30W, where SPR tested...

OIC, just the maximum amount of heat a cooling system may have to deal with. :oops: In that case, I wonder if a Turion would be worthwhile? Maybe from a performance POV, but it doesn't look like it would drop power consumption much. It ain't as bad as the picopsu type PS'/AC bricks in terms of cost ...

I have a Sempron 64 system w/ a FX5200, old soundblaster card, and generic TV card in the AGP/PCI slots as well as one of those "green" WD 500gb drives. According to my killawatt, the power consumption at idle w/ my processor undervolted/underclocked as low as it'll go (800mhz/.85V) is ~46W, and w/ ...

If you're building it yourself, as many used parts as possible. That is gonna have a much larger impact on the lifetime carbon footprint than cutting energy use by even 50%. Depends on what it's used for. As the uptime increases the relative amount of energy for operation compared to construction c...

It's marketed to the Web-savvy under-30 set, but unless you give it to someone who has a lot of time to learn the basic nuances of Linux (or at least how to install plug-ins on Firefox), I see the gPC as one of those PCs you buy as a gift for the holidays and return to the store in January. Meh? Se...

I'd love to nab a laptop drive or a picopsu but given the current prices I'm seeing they may never pay themselves off in terms of power consumption/savings. I've read some stuff that seems to support what you're saying about switching to another motherboard and others saying that going w/ a m-atx se...

I'm shooting for 50W consumption at max load. So far, given my current config, using cpufreq to drop the clock from 1.8ghz to 1ghz dropped power from ~115W to ~85W. I should be able to get another 5-10W from a 80+ PS, so in order to get to my goal I would need to either -Cut more from the processor ...
