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).
As the ASUS board has the EPU-6 software we are not surprised to see it at or near the top of the list for stock speeds. When we overclocked the CPU that is when things get interesting. We see dramatically increased power usage from the system. The same thing can be said once we dropped the HD 5870 on to the board and asked it to perform for us.
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.
Heat generation was something of an issue on the P7H55D-M. Due to the small size of the heatsink on the H55 chipset we saw temperatures that were much higher than expected. It was something of a shock to see them in the 40c range to be honest. However, this was on an open stand without the normal air flow patterns you would have inside a case. It is possible that you would see better thermal performance there.
The ASUS P7H55D-M EVO is a nice little board. You will not win any gaming or overclocking medals (although it does clock well), but it will serve you well in the function of a mid-range or business system when you combine it with one of the Clarkdale CPUs.
Of course, if you are using this as an inexpensive base for a system then you can get quite a bit more from it. As a socket 1156 board you would potentially drop even a Core i7 in and then add on a great GPU. After all, with a cost of only $120 from Newegg.com you are getting a great board for not a lot of cash.
