J&W X48D2-EXTREME Motherboard - Power Usage and Heat Tests

J&W are a new motherboard company trying to make a name in a very competitive field. Today they show us their X48 board.

Power Consumption

 

We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).

 

There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.

 

The other thing to remember is that our test system is bare minimum - only a 7,200RPM SATA-II single hard drive is used without CD-ROM or many cooling fans.

 

So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.

When it comes to power usage, J&W has done a great job at keeping the power down on the X48 chipset. While it's higher than the rest of the pack, it's still not a huge figure. The solid state components help along with DDR2 memory to keep things going.

 

Heat Generation

 

As a new measure, we are now monitoring the heat generation from the key components on the motherboards, this being the Northbridge, Southbridge (if it contains one) as well as the Mosfets around the CPU. The results are recorded at idle and load during the power consumption tests.

J&W's heatpipe may be a bit of a pain to install power cables and heatsinks around, but it does the job in keeping the components cool, especially the Northbridge which gets pretty warm on most X48 boards.
