READY FOR MODERN STANDBY
Modern Standby is a feature for Windows 10 that allows your PC to wake from sleep faster, and maintain a network connection during sleep to continue downloads and receive updates, with less overall power consumption.
To make use of Modern Standby, a compatible motherboard and CPU are required.
TUNED FOR LOW NOISE OPERATION
A 135mm rifle bearing fan with a specially calculated fan curve ensures that fan noise is kept to a minimum, even at full load. When at low and medium loads, the fan stops spinning entirely until it’s needed, resulting in virtually silent operation.
A 160mm-long casing ensures an easy fit in almost all modern enthusiast PC cases, providing more space for cable management and airflow in your chassis.
PCI-E connectors to power dual or triple (RM850 only) GPUs for your most ambitious PC gaming builds.
