Design and features
As the low-end P8Z77-V LX model, the
P8Z77-V LK is narrower than the ATX form-factor but retains the way of classic
component layout that does not affect usability.

P8Z77-V LK Mainboard image
Supporting all kinds of LGA1155 CPUs, the
mainboard has a digital 4 +1 +1 power system. In contrast to the low-level
model, some of the voltage regulator components are covered by another heatsink
protected by the spring plastic latches. The chipset heatsink employs the same
kind of splint. Similar to the rest of the ASUS mainboards, this model can take
up to 32 GB of DDR3 SDRAM and generate the pulse at frequencies of 800 to 3,200
MHz (with an Ivy Bridge CPU). Storage devices are connected through the Intel
Z77 Express chipset, two SATA 6 Gbit/s connectors (the gray color) and four
SATA 3 Gbit/s ports (the blue color). There are no other SATA controllers here.

Unlike its low-level brother, the P8Z77-V
LK can share the 16 PCIe 3.0/2.0 entrances between two graphics slots,
supporting multi-GPU configurations based on NVIDIA SLI and AMD CrossFireX
technologies. In the latest models, you are able to even use a third slot (the
black, in PCIe 2.0x4 mode) with the position of both PCI Express 2.0x1 slots
that are disabled. In addition to that, there are two PCI slots that are
available for the expansion cards. The P8Z77-V LK also contains an additional
ASMedia ASM1042 controller that is responsible for the two USB 3.0 ports of the
back panel.
The
connectors
·
Universal PS/2 connector for keyboard and mouse;
·
Two USB 2.0 ports, another eight ports are laid
out as four onboard pin-connectors;
·
D-Sub, DVI-D, HDMI and DisplayPort video outs;
·
Four USB 3.0 ports (blue connectors), two of
which are implemented via ASMedia ASM1042 controller. Another two ports and one
more internal pin-connector for two additional USB 3.0 ports are provided by
Intel Z77 Express chipset;
·
A local network port (network adapters are built
on Gigabit Realtek RTL8111F controller).
·
An optical S/PDIF and six analogue audio-jacks
provided by eight-channel Realtek ALC892 codec
·
Universal PS / 2 connector for keyboard and

As the P8Z77-V LX, this model has wide and
convenient Q-Slot latches on the graphics slots meanwhile in the memory slots
have the normal latches. The MemOK button allows the mainboard to boot
successfully in case of problems with the system memory. The GPU Boost
converter can automatically accelerate the clock speed of the CPU-integrated
graphics core. The EPU (Energy Processing Unit) converter can be used to
activate the power-saving modes, but the mainboard lacks a TPU switch (TurboV
Processing Unit) to overclock the CPU even though it does not support the
TurboV technology. There is only one indicator (DRAM LED) outside the Q-LED
system available on the other ASUS mainboards. Additionally, we are able to see
Standby Power, EPU GPU Boost and LED. The four fan connectors are for all of the
4-pin types. Compared with the high-end models, the P8Z77-V LX lacks
technology-updated software of USB BIOS Flashback.
