J&W MINIX 890GX-USB3 Mini-ITX (AMD 890GX) Motherboard - Power Usage, Heat Tests and Final Thoughts

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).






We are sure that it comes as no surprise that the MINIX 890GX is not a power hungry board. Even with the Phenom II X6 thrown in we still see excellent power efficiency.


Heat Generation


As a new measure, we are now monitoring the heat generation from the key components on the motherboard; 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.






As we expected, the MINIX ran a little hot. It is certainly not the hottest board we have had in the lab, but if you plan on using it you might want to swap out the thermal pads for thermal paste and clamp the heat sinks down a little better.


Final Thoughts


The J&W MINIX 890GX-USB3 is a pretty tough little board. We have tried this same stunt in other Mini-ITX boards and we could not get past the POST, let alone actually finish our full testing suite.


The fact that this board seems to be able to handle a Phenom II X6 1100T without missing a step speaks volumes about its design and quality. Of course, we cannot guarantee that every 890GX will be able to do this, but we have a feeling that you would not be disappointed if you tried it.


Of course, there are other reasons to grab one of these. After all, you have dual GBe LAN ports, N-Spec Wireless, good Audio, room for a full sized PCIe video card and more. The down side is that you will have to spend a bit of time getting all the drivers installed as the shipping driver DVD seems built for XP and not much else.
