Seasonic SYNCRO Q704


The following system was used to test the case:
– Processor: Intel i5 4690K @ 4.5 GHz
– Motherboard: MSI Z97 Gaming 9 ACK
– Memory: Corsair DDR3 16GB
– GPU: ASUS GeForce GTX 780 Ti Direct CU II
– SSD: Crucial MX 500GB
– Mass Storage: WD 1 TB Blue
– PSU: Seasonic Connect 750W
– CPU Cooler: Intel Stock
– OS: Windows 10 64-Bit (After April Update)


The interior of the SYNCRO Q704 is big enough to accommodate any system you can imagine, apart from exotic form factors. The default fan and airflow configuration is efficient, with three fans as intake and just one fan as exhaust, this case has a positive airflow configuration. This type of configuration will deliver the best performance and keep most of the dust away from the interior components of your system.


The wire management is made easy thanks to the Seasonic Connect module which acts as a bridge or a secondary modular panel for the cables. In simple terms, the power supply has only a single cable with a large connector that hooks up into the Connect module. Afterwards, the needed cables to power your system are connected from the Connect module to your components. This reduces the cable clutter inside the system and at the back of the motherboard tray by about 70% if not more.

Final thoughts

The Seasonic SYNCRO Q704 is an amazing case and for a first product of this type for Seasonic, its impressive. The design of this case is good, but looks are subjective so you might disagree on this.

One of the biggest features of this case is the fact that it comes with an included power supply and a unique technology, the Seasonic Connect module. The included power supply is nothing short of great, it’s basically what you can buy right now as a standalone product from Seasonic but with a different modular system and cables.

However, this included power supply and new technology comes at a price, quite literally, the Seasonic SYNCRO Q704 with the included 750W Gold rated power supply costs no less than 460 USD or 407 EUR. That is a lot to spend on just a case and a power supply alone. Yes, the value is there, but it’s a lot of money especially in the today’s world where graphics card pricing has gone through the roof.

In terms of the quality, it’s nothing short of amazing. Everything is made from metal and solid plastic, even though the plastic is limited to the dust filters. The structure of the case is solid and the same can be said for the front panel and the two large stands. This level of build quality should become the norm on flagship and high-end cases.

The cooling is great thanks to the included Nidec Servo fans, which not only look good, but they do perform as expected. The Nidec fans are the same fans that everyone was using in the past for as radiator fans. That was done because these fans delivered a great static pressure and airflow.

This is one of the few cases that earns the editor’s choice award, the other two being the Fractal Design Torrent RGB and the be quiet! Silent Base 802. The Seasonic SYNCRO Q704 is in a league of its own though, not because of the design but because of the way it’s being built. This case looks and feels to be made with performance as its focus.

However, there are drawbacks, first being the high price, and second the inverted layout which cannot be changed. While the inverted layout has its benefits in terms of cooling and airflow, the fact of the matter is that the glass side panel is on the other side of where everyone wants it, and that’s an issue from a design perspective.

In conclusion, the Seasonic SYNCRO Q704 is an amazing case that offers a great performance and a few unique features that make it stand out. The inverted layout is functional and easy to work with, and the included power supply will last a lifetime, or at least until the 10-year warranty runs out.
