Intel LGA775 motherboard

Street Price US$360~430

The Asus P5E3 Premium is Asus' flagship Intel motherboard and sells for around $400, which is enough to buy a whole computer system these days, albeit an economy model. Despite the ultra-high cost, PC gamers and enthusiasts drool over such products. Asus has thrown everything they have up their sleeves in making the P5E3 Premium the ultimate motherboard. The board is powered by Intel's X48 chipset, featuring PCI-E 2.0, CrossfireX capability and ultra-fast DDR3 memory support. It also has plenty of practical features including FireWire, gigabit ethernet, high definition audio, wireless draft-N, and versatile RAID options. In this board's endless feature list is something Asus calls EPU.

The P5E3 Premium ships in a sleak black box with a plastic handle.

EPU (aka Energy Processing Unit) is a built in IC controller that Asus claims can create up to 80.23% in CPU power savings. It accomplishes this by adjusting the CPU's power phases from 8 to 4 during low load, allowing for higher VRM efficiency. This chip was the center of a controversy between Asus and Gigabyte earlier this year after Gigabyte not only claimed their DES (Dynamic Energy Saver) technology was superior, but also made some disparaging remarks regarding Asus' claims. DES, as the name suggests, is more dynamic in nature, adjusting the power phases variably rather than just having two states. After several back-and-forths and the threat of a lawsuit, Gigabyte issued an apology in July, though still insisting DES is the better technology.

8-phase power is lowered to 4-phase during light load by the EPU chip, resulting in greater VRM efficiency.
