Performance You Can Rely On
ASUS M51 Desktop PC equipped with the latest 4th generation Intel® Core™ processors and NVIDIA® GeForce® GTX graphics for smooth multitasking and high-performance gaming. M51 desktops also feature ASUS Smart Cooling technology for cooler and quieter operation, and ASUS Power Pack — a removable UPS (Uninterruptible Power Supply) that can also be used as a portable battery recharger for smartphones and tablets. In addition, the M51 is its first desktop PC to feature ASUS SonicMaster audio technology for enhanced sound quality.

Horsepower at Your Command

The Force Shield Experience
Leading in satisfaction with reliability

ASUS computers reflect a tradition of the finest quality, innovation and longevity. Based on the PCWorld USA 2012 reader survey of tech satisfaction, reliability, and service, users ranked ASUS as a leading choice for desktop PCs, citing high satisfaction with their value, connectivity, ease of use and reliability. The survey also found ASUS desktop PCs were one of the most likely to be recommended to others.

ASUS Power Pack
ASUS Power Pack is a mobile charge station that can charge devices on the go. When plugged into the desktop, it acts as an emergency power supply keeping the desktop powered for 25 seconds if there is a sudden power loss. If a power cut last longer than 25 seconds, it will enter hibernate mode automatically so that no important data is lost.


Engineered to be cool and quiet
The exclusive ASUS Smart Cooling System reduces dust accumulation, lowers operating temperatures by up to 11.4℃2, and adjusts CPU fan speeds according to its current load for stable, reliable operation.

The best motherboards in the world
ASUS desktop PCs are built on the best motherboards available — and we should know, because we make them. We’ve sold 465 million motherboards since we first started making them over 24 years ago and our models won over 1, 000 awards in 2012 alone.

Factory-tested for perfection
ASUS desktop PCs are subjected to a series of rigorous tests to ensure they meet our exacting standards — and exceed those used by other manufacturers. So you can rest assured that your new computer can cope with everything from extreme temperatures and humidity levels, to the demands of being shipped around the world.

Complimentary 32GB ASUS WebStorage
With 32GB of ASUS WebStorage provided free for three years, you can keep your important data safe in the cloud and access it on any device with an internet connection. Say goodbye to insecure USB flash drives, stream music when you’re on the move, and share photos with family and friends just by sending a link.

Nest-generation Connectivity
USB 3.0 with Ai Charger Technology
SuperSpeed USB 3.0 delivers up to 10 times faster transfer rates compared to previous generation USB4, and charges devices up to 50% faster.

SATA 6Gbit/s Ports
ASUS desktop PCs support blisteringly fast data transfer speeds with internal storage devices, so everything from saving large files to loading new game levels is quicker.

Wireless Charger
ASUS M51 desktop PCs feature Qi — a cable-free recharging technology for mobile devices*. Just place a Qi-compatible smartphone or tablet on the supplied recharging tray and the battery recharges just like it was plugged into a USB port, but without the fuss of plugs and cables.

ASUS Universal Storage module (USM)
The ASUS USM makes expanding hard drive storage easy and offers data rates twice that of USB 3.0.
