In recent months Seasonic have released some fantastic power supplies in the high end sector – such as the Titanium rated Prime TX-1600 (review HERE). Having a more affordable range of units is critical to maintaining market share, and this is exactly where the new FOCUS 80 Plus Gold range fit in.

The FOCUS GX-1000 is a very capable power supply that exhibits no major weakness in any area. Load regulation is tight and the unit coped with the cross load test without any issues. The adoption of a high grade Fluid dynamic bearing fan and 105c rated Japanese capacitors will ensure long term reliability.

Ripple suppression rates highly, with +12V peaking at 20mV at full load, while both secondary +3.3V and +5V rails peak at 10mV. These are at the top of the class in regards to Gold rated units we have tested in recent years.

The unit achieved both 80 Plus Gold rated certification in our tests as well as delivering almost 1,150 Watts before shutting down safely. This is an overspec'd unit that will handle 1000 watts load for many hours if required. Obviously if you need 1000 watts output for any length of time we would recommend something like the aforementioned Prime TX 1600, as efficiency levels and noise output would be much lower, and less strain would be placed on the capacitors.

Noise output on this unit is quite low and never intrusive due to the excellent Hong Hua FDB fan. The fully modular design and small physical footprint (140mm) will ensure this unit will fit into a vast myriad of chassis designs without routing issues. Seasonic also back this unit up with a 10 year warranty for peace of mind.

Pricing is competitive. The GX-750 unit is targeted at £119.99, the GX-850 at £149.99 and this flagship GX-1000 is priced at £179.99. Just be sure to get this latest ATX 3.0 model with an EAN of 4711173878049.

Pros:

• Exceeds 80 Plus Gold rating.
• 105c rated Japanese capacitors from Nichicon and Nippon Chemi Con.
• low noise levels.

KitGuru says: One of the best 1000 watt 80 Plus Gold rated power supplies we have tested. It delivers quality power well in excess of 1000 watts without making too much noise. The internal design is top drawer and adopts high grade 105c rated Japanese capacitors to ensure long life and reliability during high draw sustained load environments. The 10 year warranty offers extended peace of mind.
