617335 2007-12-02 05:54:00 Where can I find Information to enable me to assemble or buy an energy-efficient PC? Which chips/motherboards would be the best basis for such a system? I want to combine reasonably good performance with efficiency.

617336 2007-12-02 06:40:00 I can tell you what components save power, if you want to know as it saves so much time. JUST INSANE (6682)
617337 2007-12-02 07:17:00 Thanks for the suggestions. I will check them out. Where did you get the info to know that these items are energy-efficient compared to other components? (There might be some new even better ones available now).

617338 2007-12-02 07:36:00 Those were not my suggestions as it was my computer specs under signature.
Most of my facts are harvested through tomshardware and or sites over the years.

What are your requirements. Is it only powersaving.

617339 2007-12-02 08:17:00 Hi Just Insane, I am also looking for an energy efficient, quiet PC with plenty of "guts". If that is not contradicting with the before said.
Let's see ?
Thanks NT

for energy efficient then a laptop would be best. nearest would be a desktop equivalent of one.

617341 2007-12-03 01:26:00 The AMD Athlon X2 BE series are by far the most energy efficient CPU's available today for the desktop when you take into consideration performance. VIA's C7's are more energy efficient but offer very lackluster performance. Otherwise there are a couple of mATX motherboards available that use laptop sockets meaning you can use laptop CPUs in them, but they are very expensive.

AMD's 690 chipset is by far the most energy efficient chipset, Intel and Nvidia don't even come close. The new 770 and 790 chipset being released shortly are also very energy efficient and provide a good option if your a tweaker/overclocker. If your not a gamer then the integrated graphics in the 690 uses little extra power and is sufficient for Vista.

A laptop harddrive or solid state drive would be the best bet for storage.

617343 2007-12-04 05:11:00 In my opinion and energy efficient low cost pc will be:

(CPU) Intel Pentium D 2140

(MOBO) Gigabyte GA-945GCM-S2L

(Hard Drive) Western Digital 250GB Sata 2 16mb 7200 Rpm

(Memory) G.SKILL 2GB KIT (2X1GB) F2-6400PHU2-2GBNR DDR2-800

(PSU) AcBel 400W

(Monitor) Dell 19 inch widescreen LCD

The CPU is low power efficient and if tweaked properly it can be used in demanding programs.
The Motherboard has intergrated graphics and supports faster FSB.
The Harddrive is the cheapest per gigabyte.
The LCD Monitor is going cheaper than other monitors may get for $270.

617344 2007-12-04 05:18:00 This (www.digit-life.com) review show the Athlon X2 BE's beating the Intel Pentium E2140 in most benchmarks but it also consume more power at both idle and load. Since the E2140 is cheaper its probably the better buy, but Intel's integrated chipset suck big time. They consume far more power than they should and offer very lackluster video performance. AMD 690G is a far better chipset. Pete O'Neil (6584)
