In The Blue Corner: The Atom D525 Challenger

Efficiency Analysis: Atom D510 Vs. Atom D525/ION2
By , Achim Roos

Jetway NC98-525-LF with Atom D525 and Nvidia ION2

This motherboard is based on the mini-ITX form factor and includes the processor soldered right onto the PCB. The solution is based on the Intel NM10 chipset plus Nvidia's ION2, which helps improves graphics performance. Jetway adds an HD audio codec, four USB 2.0 ports, and DVI-D, as well as HDMI for attaching display connectivity. However, the board has no expansion slots, except for one mini PCIe slot, as a result of space constraints on the 170x170 mm form factor. Be aware that Jetway offers this board in different models with either the Atom D510 or Atom D525 processor.

There is no ATX connector on this motherboard. Instead, it employs a 12 V connector on the rear panel, which is used to deliver power through the external PSU. Since we had to run both Atom solutions with an identical power supply, we used the same Enermax Pro 82+ unit. For purely testing purposes, we attached the ATX 12V conductor and ground wires to the 12 V power connector using a soldering iron. This worked well, even if it's only a temporary solution.

The motherboard comes with a single Molex power connector. This allows you to connect one drive right away. You'll need to use a Y-cables if you want to install more than one internal drive. Finally, it’s important to ground the green power supply wire to make sure that the system turns on when you switch on the power supply.
