1000 W ATX 3.1 power supply

The Dark Power 14 delivers 1000 W through an ATX 3.1 design that includes a native 12V-2x6 connector for PCIe 5.1 graphics cards. Its fully modular cabling keeps the build clean and suits high-end workstations or enthusiast gaming rigs.

Sustained-load behaviour

80 PLUS Titanium and Cybenetics Titanium certification confirm up to 95.5 % efficiency across the load range, so waste heat stays low during long rendering or compute sessions. An aluminium heat sink and a 135 mm Silent Wings fan run in active or semi-passive mode, selectable by a button, to maintain stable temperatures without audible noise.

ATX 3.1 interface limits

The PSU complies with the ATX 3.1 specification and supports the 12V-2x6 connector rated for up to 600 W per cable, while also providing traditional 6+2-pin PCIe plugs for older GPUs. Full bridge topology with synchronous rectification and LLC resonance ensures tight voltage regulation under transient spikes defined by the standard.

Questions about this item

How loud does the 135 mm Silent Wings fan get when the 1000 W unit runs all day under load?

The power supply offers active and semi-passive modes selectable by a button; in semi-passive mode the fan stops at low loads, and the aluminum heat sink plus high Titanium efficiency keep temperatures low for quiet continuous operation.

Which cables or connectors must my system already provide for this ATX 3.1 unit to work?

Your motherboard needs a 20+4 pin main power socket, and any PCIe 5.1 graphics card will use the native 12V-2x6 connector included with the modular cable set; older GPUs can use the supplied 6+2 pin cables.

Will the modular cable set support an older GPU that only has 6+2 pin power inputs alongside a new PCIe 5.1 card?

Yes, the modular design includes both the 12V-2x6 connector for PCIe 5.1 cards and traditional 6+2 pin PCIe cables, so legacy and next-generation graphics cards can be powered simultaneously.
