Sharky Extreme bevestigt in zijn IDF Report dat de Pentium 4 een nieuwe behuizing en voeding vereist. Intel heeft hiervoor namelijk speciaal de ATX 2.03 specificatie in het leven geroepen. De power supply moet zoals bekend voldoen aan de ATX12V specs. Hieronder meer info:
Intel had a new revision of the ATX spec made for the Pentium 4 to cover its various physical needs. The ATX 2.03 specification covers the new case, motherboard, and power supply designs needed to be compliant with Intel's reference Pentium 4 platform design. This will have a direct impact on you if you ever plan on purchasing a Pentium 4 system, so we suggest you read this section and what we think the consequences will be. This will have less of an effect on companies like Dell, IBM, and Compaq, who tend to design their own platforms off of what Intel designs.
On the case side, ATX 2.03 specifies four new screw holes on the motherboard tray. These screw holes are needed to mount four screw-in supports that lie under the Pentium 4 processor. These four supports are to hold up the reference Pentium 4 heat sink, which we will talk more about later in the article. There are no cases we know of available today that meet the ATX 2.03 specifications, so we suggest you hold off on buying that $200 super cooling case if you think you might ever get a Pentium 4. Don't fret though, we do expect that you will be able to manually drill the four holes into an old case in order to mount a Pentium 4 without having to buy a whole new case.
The Power Supply
On the power supply side, ATX 2.03 includes a new kind of power supply specification called ATX12V. ATX12V power supplies will have two main differences from normal ATX power supplies:
There is a new +12V power connector and more +12 VDC output capability. This connector will provide more usable power to the CPU area of the motherboard. The Pentium 4 is a high-power processor and, by having a second power connector, motherboard manufacturers won't have to route a large amount of power across several crowded inches of motherboard. Power will instead be delivered closer to where it is needed. ATX12V cases will also need to provide more +5 VSB current. The minimum is now 1.0 amps with 2.0 amps preferred.
ATX12V cases will be fully compatible with systems that need previous ATX power supplies. In other words, an ATX12V case would work fine with most of today's motherboards. However, an ATX power supply will not work with a motherboard that needs the extra +12 V power connector.
