We’ve mentioned a number of downsides about the ASUS Z87-Deluxe throughout this review. Like all ASUS mainboards, it doesn’t provide any prompts about active hotkeys and doesn’t report the correct CPU clock rate when starting up. You may find it difficult to enter its BIOS interface. Not all of its power-saving technologies are enabled by default. And the CPU doesn’t work in its standard mode at high loads.
We had no problems with the mainboard’s overclocking features, though. ASUS mainboards turned out to support energy-efficient overclocking of Haswell-based CPUs without volt-modding, so the power-saving technologies were not disabled. As for its performance, the mainboard is about as fast as similar products from other brands.
We like the new options of ASUS’s EFI BIOS, especially the popup BIOS Setting Change window that show the list of changes to be applied. Besides various fine-tuning and overclocking options, top-end ASUS mainboards, including the Z87-Deluxe, offer a number of unique BIOS options in the CPU Power Management section which lower the mainboard’s power draw in idle mode. Despite this, the Z87-Deluxe turned out to have the highest power consumption among all the Z87-based mainboards we’ve tested so far.
Some of the errors in ASUS’s BIOS we had noticed earlier have been corrected, but BIOS profiles still do not save your turning off the startup picture. The mainboard cannot regulate the speed of 3-pin CPU fans. The power-saving options of the CPU Power Management Configuration page are hard to access whereas the My Favorites section contains a limited number of options and cannot be used as the start screen. Other sections can’t serve as a start screen, either. EPU Power Saving Mode with exclusive power-saving features has lost its flexibility.
Other mainboards have downsides of their own, even more serious ones, so we think the ASUS Z87-Deluxe is a good mainboard overall. Moreover, we think it is more balanced than other top-end LGA1150 products from ASUS. It features additional SATA 6 Gbit/s and USB 3.0 controllers, supports Wi-Fi 802.11a/b/g/n/ac and Bluetooth, has two Gigabit Ethernet adapters, and offers two CPU fan connectors and two POST code indicators. Its Q-Design technologies simplify the process of building a computer with this mainboard. USB BIOS Flashback allows to easily update the mainboard’s firmware. And the AI Suite III software is really useful, unlike utilities offered by many other mainboard makers. So, if you’re choosing from ASUS’s top-end mainboards, you should certainly consider the ASUS Z87-Deluxe.
