One Clean Solution


The state-of-the-art Seasonic SYNCRO Q7 Series is a mid-tower ATX chassis that features an aluminum body and a tempered glass panel on one side and the Seasonic SYNCRO CONNECT Module* on the other. This setup can accommodate powerful hardware and provides versatile cooling and ventilation options. The SYNCRO CONNECT Module* functions as a cable management hub, to which the components are directly connected with generally shorter cables. This setup simplifies cable routing and allows for a clean look on both sides of the case.

* In North America, the SYNCRO Q704 is comprised of a PC chassis with four pre-installed fans. The SYNCRO power supply plus CONNECT Module set is sold under a separate listing.

In the EU and the UK, the SYNCRO Q704 case is sold together with the SYNCRO Power Supply plus CONNECT Module as a bundle. For more information about the power solutions, please follow the link here: SYNCRO Power Supply plus CONNECT Module.

One Clean Solution

When used in tandem with the SYNCRO case, the Seasonic SYNCRO power supply plus CONNECT Module set keeps both sides of the case neat and tidy.

Optimized Airflow

Inverted ATX design prevents the rising heat emitted by the GPU from increasing CPU temperature.

Ventilation holes on each side of the case ensure sufficient airflow.

High-performance Seasonic-Nidec Fans

Factory installed four high-performance, Seasonic-Nidec, dual ball-bearing fans provide powerful, yet silent cooling. Up to eight cooling fans can be installed for extended cooling solutions.

Simplified Maintenance

Large-sized dust filters on the front, top and bottom sides of the SYNCRO Q704 are kept in place by magnets and can easily be removed for maintenance and cleaning.

Multiple Cooling Solutions

The SYNCRO Q704 provides ample space for air- and radiator cooling solutions.
