ASRock P43 and P45 Motherboards Reviewed - Power Usage and Heat Tests

Today we have a double header for you from ASRock with their P45 and P43 top rocks.

| Socket LGA 775 in Motherboards | Posted: Aug 4, 2008 4:00 am

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 3DMark Vantage 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.

Power wise; both chipsets perform identically. They are mirror images of each other.

 

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.

The P45 board runs slightly hotter on the MCH, but this could be due to its dual PCI Express x8 capabilities.
