NZXT 1200 W ATX 3.1 power supply

This 1200 W unit follows the ATX12V v3.1 and EPS12V v2.92 specifications. It is built for systems that need high continuous power from a single +12 V rail rated at 100 A. The fully modular design lets you connect only the cables your build requires.

Check ATX 3.1 compatibility and cable reach

Verify that your motherboard and graphics card accept the ATX 3.1 power standard before ordering. The 24-pin ATX cable is 600 mm long with nylon sleeving. Both CPU power cables measure 700 mm, one 4+4-pin and one 8-pin, also sleeved for durability.

135 mm FDB fan, 160 mm depth, gold efficiency

A 135 mm fluid-dynamic-bearing fan handles cooling while the active PFC runs at 0.99. The chassis measures 150 x 86 x 160 mm and carries 80 PLUS Gold certification. Protections include OVP, UVP, SCP, OTP, OPP and OCP, with an MTBF exceeding 100,000 hours.

Questions about this item

Which cables come in the box and which ones must be purchased separately?

The unit includes a 600 mm 24-pin ATX cable, a 700 mm 4+4-pin CPU cable and an 8-pin CPU cable, all with nylon sleeving. Because the supply is fully modular, any additional PCIe or peripheral cables required for your build must be bought separately.

How do I decide between the available wattage options for this model?

This specific model is rated at 1200 W on the +12 V rail at 100 A, with 22 A each on the +3.3 V and +5 V rails. Choose it when your combined GPU and CPU draw approaches that ceiling; a lower-wattage unit would be a different SKU.

What does the 1200 W rating mean once the supply is installed in a system?

It means the +12 V rail can deliver up to 100 A continuously while the +3.3 V and +5 V rails each supply up to 22 A, all within the 80 PLUS Gold efficiency target and the ATX 3.1 / EPS 2.92 specifications.
