Understanding the Micro ATX Form Factor Motherboard
Micro ATX (or ?ATX) is a form factor motherboard available in different sizes from 9.6' x 9.6'to 6.75' x 6.75'. The motherboard supports Intel, VIA, and AMD chipsets or CPUs. The motherboard was released in 1997 and it was designed as a replacement for ATX form factor motherboards. Some of the advantages of this motherboard over the ATX form factor motherboards it replaced include the smaller and more compact size, the integrated devices which means fewer expansion slots, lower chassis cost, lower consumption of power, and several others. ATX form factor motherboards were developed in 1995 by Intel. microATX is backward-compatible with the original ATX. The mounting points are subsets of those used by ATX motherboards and the I/O panels are also identical. This means microATX motherboards can fit in the cases of ATX motherboards. ATX motherboards and microATX motherboards also share power connectors. The two boards also share chipsets which are southbridges or northbridges. However, cases for microATX are generally smaller. The standard ATX motherboard size is 25% longer than a microATX motherboard at 12' wide x 9.6'deep.
Modern ATX form factor motherboards come with more than 5 PCI/ PCI-Express expansion slots while microATX form factor motherboards only come with 4 as the maximum. This is the reason why microATX motherboards come with integrated peripherals such as integrated graphics cards. An example of this is Asus A8N-VM CSM motherboard which comes with an onboard GeForce 6 graphics card, AC'97 audio card, and a gigabit Ethernet adapter. The power supply has three main outputs and these are +3.3 V, +5 V and +12 V. You could also get supplies with 5 VSB (for standby) and ?12 V (for low power). microATX cases support 6 SATA devices and 4legacy IDE drives only. If you so wish, you could maximize the capability of these motherboards by setting them on ATX cases. Note that some microATX cases that use power supplies that do not have standard dimensions will require LP PCI cards.
The careful design of microATX motherboards is done to give cost savings resulting from reduced output power supply, reduced costs of chassis, and minimum redesign of older ATX-compliant chassis. Other benefits of microATX motherboards over traditional ATX motherboards are space saving, meaning the case can easily fit in a small work station, more I/O spaces at the rear, and reduced emissions because of integrated I/O connectors. These motherboards have 'must-have' functions and you therefore need to know what these are when going computer shopping. Other form factor motherboards that are competing with Micro ATX include Nano-ITX 120 ? 120, ESMexpress125 ? 95, COM Express 125 ? 95, Mini-ITX 170 ? 170, BTX 325 ? 266, Baby-AT 330 ? 216, ETX/XTX 114 ? 95, PC/104 (-Plus) 96 ? 90, Pico-ITX 100 ? 72, FlexATX 229 ? 191, EBX 203 ? 146, ESMini 95 ? 55, LPX 330 ? 229, microBTX 264 ? 267, DTX 244 ? 203, Mini-DTX 203 ? 170, and EPIC (Express) 165 ? 115.
You could get specifications from the latest version and revisions of microATX Motherboard Interface Specification which indicate key changes such as the recent change of the pins in the Main Power Connector which changed from 20 for PCI interface to 24 ( 2 x12) to support PCI-Express interface.

The Board Also Houses Several Interfaces For Countless Gadgets
Upon reviewing my expertise with the Information Technologies society, I found that we are as well few. Essentially we are to numerous by count of inexperienced "technicians," to this kind of a degree, that I have made a decision to begin creating an introductory article on computer systems and their elements. Within this post I is going to be detailing the main elements of a regular desktop and/or tower personal computer. The article you read now includes an explanation of important elements, developed to offer an introduction to computer systems. In the event you know (or think you know) what the components are currently please do not waste your time reading this post as it's going to quite possibly be fairly redundant and boring to you. Over the training course of your studying I'll clarify what motherboards, Processors, Power Supplies, Memory, challenging drives, Reliable State Drives, and expansion cards are, as well as what they do.
The motherboard (also recognized because the mainboard or mobo) is the basis component that computers have to have as a way to do anything. Without this component your computer wouldn't function. It wouldn't even be considered a computer system mainly because it would not determine what a function was to begin with. The motherboard comes in a number of forms, essentially the most widespread of that are mini-ITX, ATX, and e-ATX. The board also houses many different interfaces for a number of gadgets. Serial ATA (SATA) and ATA (typically referred to as IDE) are the most typically employed gadget interfaces. You can find also many sets of pins around the board for USB interfaces. These are clusters of pins are called "headers" and allow enlargement. Also on the mainboard there's a set of plastic slots (normally situated subsequent towards the CPU) for memory. In towards the memory slots, you will uncover a number of diverse sorts of growth card slots, such as PCI, PCI-e x1, and PCI-e x8 or x16. These expansion slots allow the user to later on put in cards that can supply assorted capabilities in the as well as offering a foundation for personal computer. None of this issues with out two other components, the very first of that is the Processor.
Central Processing Models (also recognized as processors or CPU's) will be the brains with the whole operation. This component may be the mind with the computer. In an effort to do anything your laptop have to possess a effectively installed CPU. When installing a CPU, be sure that which you align notches on the chip itself using the notches around the CPU socket. This will guarantee that you don't harm the CPU or motherboard. The following step is usually to set up the heatsink and fan to cool the processor. When putting in these cooling merchandise you should use thermal compound. Thermal compound can be a paste that transfers warmth through the metal with the CPU towards the metal with the heatsink. With out thermal paste is pointless. To set up the heatsink, you 1st administer a tiny amount of thermal paste (via brush or syringe) onto the CPU. (It really is really significant not to get any thermal paste around the pin aspect of the CPU.) Immediately after applying thermal paste, you can align the heatsink using the plastic on the motherboard after which press down firmly. You might be now prepared to set up the memory.
is it possible to replace a mac 4g power supply with a non mac one e.g a atx power supply?
i have a mac g4 mdd (mirror disk door) it came with no power supply unit and it looks like i wont be getting one any time soon thanks to demand foir them on ebay and price ect
It can be done, but don't expect to close the case without some major modifications. You'll likely need to do a little cutting and splicing, though, as I don't think any G4 has an ATX pinout.
Even more recent events in Solar Power (Metafilter)
Some interesting things have recently happened in the world of solar power:
Evergreen and Solyndra have gone bankrupt, panel cost has gone sub $1.00/watt,
and China has vastly increased production capacities.
Before getting to the much-publicized Solyndra, let's see what happened to
Evergreen. Evergreen built a hugely expensive facility in the Boston area.
Certain parts of Evergreen's assets have already been auctioned off, including
7.8 megawatts of 200W to 215W panels which were purchased by SunElec, a
wholesaler in Miami. These were sold off in a couple of days at 78 cents/watt,
minimum quantity one pallet.
What went wrong with Evergreen? They received tax breaks from the state of MA
to set up a facility there. Unfortunately, economies of scale couldn't compete
with vertically integrated solar firms in China. Their string ribbon panels
maxed out at a wattage density of around 130 to 135W/square meter, while
current generation budget panels from China are pushing 155 to 165W/square
meter.
In the past year, solar panel costs from China have dropped from $1.65/watt to
sub $1.00/watt. This has driven prices down worldwide. It's now possible to
buy low quantity (quantity, one!) solar panels made by Sovello for $1.04/watt
from US ...
