low power build thoughts
Purchased:Case:
Antec P180 Mini
HDD's:
Primary: 30GB SSD OCZ Vertex
Secondary:320 GB Seagate Momentus 5400.6
CPU:
AMD Athlon II X240 Regor(undervolted and downclocked)
Xigmatek HDT-S1283 R
Mobo:
GIGABYTE GA-MA785GM-US2H
Not Purchased:
PSU:
Antec Earthwatts 380D or another ~300W 80+ PSU in the 40 buck range
maybe electrodacus's PSU?
I need a second NIC for some VPN/routing purposes, but am not sure whats a good one for power consumption.

thanks for the suggestion.
newegg needs to put it on a free shipping sale so I can snag it!
my current PC is idling at ~125w. by idle I of course mean running the junk it always runs, none of which is very intensive.
if I could get this new one to to do 45w that would be great.
save me 11 bucks a month at winter electricity rates

I have seen posts from a few guys wth the x2 240 running them at stock speed at <.9vHFat wrote:Do any of you know the low-wattage efficiencies of these PSUs?
Any experience or links for passive cooling experiments with that CPU? I doubt it'd work in every case, even with a huge heatsink.
I figure with .8ishv and turning the clock down, it shouldnt be an issue with a big HS in the p180 mini, since it has good flow and Ill leave the fans on low...
here is the toms hardware review of the seasonic:

I think it would be interesting to see what temps you get with the fans off. With the CPU underclocked and undervolted and a case that's vented at the top, it might work.
I would be willing to try it, for no other reason and checking how the temps do

That might be hit and miss on getting the CPU to run under .9V. I managed to get mine down to 1.125 in the BIOS and tested with an overnight burn in of Prime95 so I wouldn't encounter any surprises. Going below 1V causes black screens on boot, but the wattage gains were minimal at best by that point (1-2W at most).Zargon wrote:I have seen posts from a few guys wth the x2 240 running them at stock speed at <.9vHFat wrote:Do any of you know the low-wattage efficiencies of these PSUs?

I noticed 2-3W variance in running XP vs Vista though (XP giving me lower idle power consumption).
any thoughts on this combo?

with the second core unlocked how much faster is the 240?

sweet. now only if I could
getting wierd errors trying to get anything loaded.

I may pull the sata dvd drive out of another machine, as I dont have the cable to use the ide one I had planned on using

moving the hdd to another port once I got server installed fixed the boot wierdness
and a new DVD drive, an asus burner thats short enough to fit up top of the p180 mini
46w at idle with everything stock!
once I get it alil more configured we'll see how it does
and I will start to undervolt it some, maybe clock it down too

having a similar "regor" rig, maybe my experience could help you:

with a good undervoltage you can idle at a 30w ish level.

very minor undervolting(mine doesnt seem to want to go to far) got me a comfy 40w idle
I had it in the low 30's but it wasnt acting all that stable. I am also not sure that the undervolt tool was really doing what it was supposed to.
any tips in that area would be appreciated
since it replaced something in the 130-150w range I suppose I shouldnt fuss with it much more. now I just need a different monitor for it, not that I use it much, but a 21" viewsonic tube surely is gobbling power when its on.

Re: low power build thoughts
wow I need to find my pictures and post them, cant believe I forgot!
this box is about to WHS or freeNAS, so its HDD setups are going to change significantly
