Seasonic Focus GX-1000 V4 (2024) ATX 3 Review

Seasonic have been my personal ‘go to' for power supplies for some time. I review a lot of PSUs and I have great success with Seasonic over the years. They are reliable and use the highest grade components inside.

This new Focus GX-1000 V4 for 2024 follows on from the previous 2023 model which scored very well in our tests last September. Seasonic are trying to refine and improve this design by adopting automated surface mount technology on a new PCB layout, as well as using smaller MOSFET and heat sink components to help improve airflow. This means when under very heavy loads the components should be running cooler and quieter.

As before, this is a very capable power supply exhibiting no major weakness in any area. Load regulation is tight and the unit coped with the cross load test without any concerns.  Seasonic always use quality $25 Hong Hua Fluid Dynamic bearing fans in this range of supply so when combined with the high grade 105C-rated Japanese Nippon Chemi Con capacitors and 10 year warranty, you know it is going to last many years.

Like the previous model, the power supply is over-specced for the 1000 Watt rating and it delivers high levels of efficiency – around 93% in our testing. Thankfully Seasonic have maintained the small 140mm deep physical footprint so it is well suited to a huge variety of chassis designs.

Seasonic now offer these new Focus GX power supplies in both black and white and while UK pricing is to be confirmed we have the following direct from Seasonic. The white versions of these power supplies are $10 more expensive than the white versions, so if your power supply is hidden from view it makes more sense to opt for black.

Pricing for the range is as follows:

• FOCUS GX-750: $ 129.99 (USA) / 119.90€ (Europe) / $119.99 (ROW)

KitGuru says: With the new range of Focus GX units for 2024 Seasonic have streamlined and enhanced the previous design from last year. This is a power supply that should be seriously considered if you have a high power PC and you have a budget around the $170-$180 mark.
