ASUS Z77-A LGA 1155 Intel Z77 ATX Motherboard

This motherboard uses the Intel Z77 chipset and fits an LGA 1155 socket. It accepts Core i7, i5, i3, Pentium and Celeron processors. The board provides four DDR3 memory slots supporting speeds up to 2400(O.C.) and a maximum capacity of 32GB in dual-channel mode.

Built for overclocking with unlocked LGA 1155 CPUs

Digital power design delivers precise voltage control for the CPU and integrated graphics. This suits enthusiasts who want to tune frequencies on third-generation Core processors. Builders using locked processors or needing newer socket types should consider a different platform.

Single PCI Express 3.0 x16 slot for graphics

The board includes one PCI Express 3.0 x16 slot active with a third-generation CPU, plus one PCI Express 2.0 x16 slot and two PCI Express x1 slots. Two SATA 6Gb/s ports and Realtek 8111F Gigabit LAN complete the main I/O.

Perguntas sobre este artigo

How much power does the Z77-A draw and how hot or loud does it get when running 24/7?

The board uses a digital CPU and iGPU power design with ultra-fast sensing to deliver precise Vcore voltages, reducing waste heat; actual draw, temperatures and fan noise depend on the installed processor, cooler and case airflow.

Which components must I already own for the Z77-A to function?

You need an LGA 1155 processor (Core i7/i5/i3/Pentium/Celeron), DDR3 memory modules up to 32 GB across four slots, a graphics card or a CPU with integrated graphics for video output, storage drives for the two SATA 6Gb/s ports, and an ATX power supply with 24-pin and 4/8-pin CPU connectors.

Will my existing PCI and PCIe 2.0 cards work in the Z77-A alongside newer parts?

Yes — the board provides two legacy PCI slots, one PCIe 2.0 x16 slot, two PCIe x1 slots and one PCIe 3.0 x16 slot (active with a third-generation Core CPU), so older expansion cards can be used together with modern GPUs.
