MSI P55A-GD65 Motherboard

Introduction

Right now MSI has 14 different motherboard models based on the Intel P55 chipset. Let’s take a look at the P55A-GD65 (a.k.a. MS-7585), a stripped-down version of their P55-GD85.

By the way, we’ve already covered two other motherboards from MSI based on the same chipset, the P55-GD80 and the P55-GD85.

MSI uses a naming scheme where the higher the number on the product name, the more features it carries. So the P55A-GD65 doesn’t have the same amount of features present on the other two models that we’ve already covered, but that doesn’t mean it is a low-end product – far from it.

Be sure not to confuse the new P55A-GD65 with an older model called the P55-GD65 (without the “A”). Despite the name, the two are completely different products:

• The new P55A-GD65 comes with two SATA-600 ports and two USB 3.0 ports, features not present on the P55-GD65.
• The P55-GD65 has two heatsinks on the voltage regulator circuit and a heatpipe connecting them, while on the P55A-GD65, one of the heatsinks was removed, along with the heatpipe.
• The position of the slots is completely different, plus the P55-GD65 had one PCI Express x4 slot, which was removed on the P55A-GD65.
• The previous incarnation had a place for measuring voltages with a multimeter, a feature that was removed on the new product.

In fact, the P55A-GD65 is a stripped-down version of the P55-GD85. Both have the same layout, but on the new GD65 the second voltage regulator heatsink and its heatpipe, second Gigabit Ethernet port, voltage measuring points, and SLI support were removed.
