    Servers that use little power

    I've been doing research, and looking around on Google for a list of processors that use little power.

    What are some of the processors out now a days that have minimal power usage?

    Chassis will be SuperMicro's with 1-4 GB ram, if that's of any use.

    If you use the latest processors from AMD or Intel, you'll save a lot of power over older generations.

    For more savings, you can try a low-voltage edition. For AMD, you could use an Opteron 2212HE or similar.

    First off, get a high-efficiency power supply for your server. They're usually not much more expensive than normal power supplies, but will save you some power in the long run.

    Are you planning single or dual processor? If single processor, by all means get yourself a new 45nm Core 2 Duo processor. They're cheap, they're amazingly fast and they don't use lots of power. The old 65nm Core 2s also work. Intel also sells the Core 2 processors as Xeon 3xxx series, but that's just a waste of money. You're paying for the brand name.

    Now, if you want dual processor, it's a bit more challenging. Intel uses FB-DIMM RAM for their new and non-3000 Xeon processors. FB-DIMM eats amps for breakfest. Consider an AMD processor, but do check the benchmarks and determine if it's good enough for you. AMD is slower than Intel and DDR2 is slower than FB-DIMM.

    Asus RS100-X5/PI2 consumes only 82.5 Watt (110V) in idle mode and 89 Watt (110V) while in full loading.

    Dell R200s are worth looking at.

    I would have to agree with this. We use nothing but the antec earthwatts 380 green power supplies. Yes, they are a bit more expensive, but they are 80Plus certified and we have yet to have one die since switching to them.

    Not entirely true for AMD desktop processors sometimes used in servers.

    "The combination of a high clock speed and a 90nm fab process brings the X2 6000+ one less desirable trait: a max thermal power rating of 125W, well above the 65W and 89W ratings of the lower rungs of the Athlon 64 lineup."

    The 6000+ is the “hungriest” processor to date. We have almost reached Intel’s record with the “Extreme Edition” Netburst dual core. The 6000+ needs even more power than the QX6700 in four sessions of Prime95.

    If you are not using dual processor/server board or can get by with P4s and alike, use a smaller case with 240Watt of power. I found out that desktop case will use less power than rackmount due to the amount of fans that are needed to cool the rackmount case (specially high density one).

    AMD X2s are great, so are the C2D and C2Q line. If you REALLY want no power, get a semperon
