1050W ATX 3.1 Power Supply

This 1050 watt unit targets high-end desktop builds that demand stable output under heavy load. It meets the ATX 3.1 standard and is ready for PCIe 5.0 graphics cards with native 12V-2x6 cabling. Full modular design lets you connect only the cables you need. The single +12V rail simplifies power distribution for modern components.

Fully Modular Ribbon Cables and 120mm FDB Fan

All cables are detachable ribbon types, reducing clutter and easing routing in tight cases. The 120 mm fluid dynamic bearing fan runs quietly while moving sufficient airflow through the 140 mm deep chassis. Active PFC corrects input current across the 100 to 240 volt range. Cybenetics Platinum and 80 PLUS Gold certifications confirm high efficiency at typical loads.

Replaces Older ATX Units Lacking Native 12V-2x6

Builders moving from earlier ATX power supplies gain direct 16-pin GPU power without adapters, reducing connection points and voltage drop. The efficiency ratings of 87 percent at 20 percent load, 90 percent at 50 percent and 87 percent at 100 percent mean less waste heat. Upgrading makes sense when a new graphics card requires the 12V-2x6 connector or when transient spike tolerance matters.

Questions about this item

What does ATX 3.1 mean for transient spikes on this 1050W unit?

The power supply meets the ATX 3.1 standard and is PCIe 5.0 ready, so it can absorb the short-duration power excursions that new graphics cards demand without tripping protection.

Will the 140 mm depth fit my mid-tower case?

At 140 mm long it fits most mid-tower chassis, but measure from the rear panel to the drive cage or motherboard tray to confirm clearance before ordering.

How do I plug the 12V-2x6 cable correctly?

Use the supplied native 12V-2x6 cable — two 8-pin plugs on the PSU side, one 16-pin connector on the GPU side — and seat both 8-pin ends fully into the PSU before attaching the GPU.
