The Seasonic Focus line got an upgrade to become ATX v3.1 and PCIe CEM 5.1 compatible. In this review I will start with the strongest member of the line (Focus GX-1000 V4) with 1000W max power.
The Seasonic Focus GX-1000 V4 ATX v3.1 is (or will be) included in my best ATX v3.x & PCIe 5.x PSU picks article.
Seasonic recently updated its popular Focus GX line, making it compatible with the ATX v3.1 and PCIe 5.1 standards. The line consists of three models with capacities ranging from 750W to 1000W. All have compact dimensions, with 140mm depth. Despite the small dimensions, Seasonic fit a 135mm diameter fan to keep noise output low. Seasonic also talks about the OptiSink design, which brings a new PCB layout to the Focus V4 units, aiming to increase reliability by improving heat dissipation and airflow. According to Seasonic’s claims, the new PCB design offers an eightfold increase in heat dissipation, keeping the operating temperatures low and increasing the PSU’s reliability.
The prices of the Focus GX V4 units are the following
- Focus GX-750: $ 129.99 (USA) / 119.90€ (Europe) / $119.99 (ROW)
- Focus GX-850: $149.99 (USA) / 139.90€ (Europe) / $139.99 (ROW)

The downfall of seasonic must be studied.
Hi, Is there a chance for Phanteks AMP GH 1000W 80 Plus Platinum ATX 3.1 review ????
Unfortunately I don’t have any connection with Phanteks anymore.
Thank you for the great review! I’m personally waiting for the ATX3.1 compliant Vertex PX-1200. But a sales rep from Seasonic told me those are currently only available in Asians markets at the time. Do you maybe have an estimate when the ATX3.1 versions of the Vertex series become available in the EU?
