The Right Power Adapter: ATX Or EPS12V, Continued
With more than 350 watts, today's ATX power adapters deliver sufficient power in order to be able to supply dual systems in ATX format as well. In the meantime, there are power adapters on the market that support both ATX and EPS12V standards with the aid of a special adapter cable. Consequently, this eliminates the need for an eventual power-adapter replacement, and it saves additional expenses incurred when changing systems. Many motherboards are capable of operating with both power adapter standards.
On the left, a 24-pin WTX plug and on the right, a 20-pin ATX plug
On the left an 8-pin WTX plug and on the right, a 4-pin PWR plug
The "20/24P" marking on the large voltage connection indicates that it can operate with the 24-pin WTX as well as with the 20-pin ATX memory. The same applies as well to the "12V-8/4P" marking on the small AUX connection - it supports the 8-pin as well as the 4-pin connections. Each of the four missing leads is a redundant voltage pin for load sharing.
The various allocations of ATX and WTX plugs
For the power adapter with the EPS12V standard, additional +12V, +3.3V, +5 V and mass leads are connected to the board.
AGP: Support For All Cards
The E7505 Northbridge offers support for AGP graphics cards, while most motherboards have a "Pro" slot. With the Pro versions, the card is supplied with additional voltage pins.
|Data Rate||AGP 3.0||1.5 V||3.3 V|
|1 x AGP||No||Yes||No|
|2 x AGP||No||Yes||No|
|3 x AGP||Yes||Yes||No|
