1300W ATX 3.0 Platinum power supply

This fully modular unit delivers 1300 W of continuous power with Cybenetics Platinum efficiency between 89% and 91%. It meets the ATX 3.0 and PCIe 5.0 specifications and includes a native 12VHPWR connector. A 120 mm FDB fan provides semi-fanless operation and delayed shut-off.

High-output builds needing ATX 3.0 native support

The 150 mm depth fits most mid-tower and larger cases, while full modularity and flat black cables simplify routing. Systems that require 89–91% overall efficiency at 50 °C ambient will benefit. Builds constrained by shorter PSU bays or lower wattage requirements should consider other models.

12VHPWR connector for PCIe 5.0 graphics cards

The single 12VHPWR (12+4) connector is the deciding specification for modern GPUs that demand the ATX 3.0 power interface. Eight 8-pin (6+2) PCIe connectors also support multi-GPU configurations. Without a 12VHPWR-equipped graphics card this specific feature remains unused.

Questions about this item

Will the 12VHPWR connector support a PCIe 5.0 graphics card?

Yes, the unit includes a 12VHPWR (12+4) connector built to the ATX 3.0 and PCIe Gen 5 standard, delivering up to 1300 W on the +12 V rail.

Does the semi-fanless mode stay quiet at low load?

The 120 mm FDB fan can stop completely at 0 dBA minimum noise, then spins up only when internal temperature requires active cooling.

Are the cables long enough for a full-tower case with bottom-mounted PSU?

The fully modular flat black cables are designed for flexible routing; the PSU body is 150 mm deep, so cable reach depends on your case layout.
