850 W ATX 3.0 power supply

This 850 W unit is built to the ATX 3.0 standard and carries 80 PLUS Gold certification for up to 90 percent efficiency. A fully modular cable set and a 135 mm fan with a zero-RPM mode keep cable clutter and noise low. It is aimed at builders assembling a high-end gaming PC that needs a native 12VHPWR connection.

Check ATX 3.0 support and case depth

Verify that your motherboard and graphics card are designed for ATX 3.0 power delivery before ordering. The power supply is 150 mm deep, so confirm the case can accommodate that length. A 100 to 240 V input range covers global mains voltages without a switch.

Fits mid-tower builds with modern GPUs

The single +12 V rail and DC-DC module design deliver stable power to a PCIe 5.0 graphics card through the included 16-pin cable. Two EPS cables, two 6+2-pin PCIe cables and twelve SATA connectors handle the rest of the system. Full modularity lets you connect only the cables the build requires.

Perguntas sobre este artigo

What cables are included in the box and is a 12VHPWR cable supplied?

The box includes one ATX cable, two EPS cables, two PCIe 6+2-pin cables, one 16-pin to 16-pin PCIe 5.0 cable, one 16-pin to 6+2-pin cable, three SATA cables and one Molex/FDD cable. The 12VHPWR cable is the included 16-pin to 16-pin PCIe 5.0 cable.

Should I choose this 850W unit or a lower wattage model for a build with a 4080 or 4070 graphics card?

The 850W rating and ATX 3.0 compliance with the native 16-pin PCIe 5.0 connector match the power requirements for 4080 and 4070 cards, providing the recommended headroom for transient spikes.

What does the 850W figure mean once the PSU is installed in a system?

It means the unit can continuously deliver 850W across a single +12V rail with up to 90% efficiency at typical loads, meeting 80 PLUS Gold and Cybenetics Standard++ noise ratings while protections guard against over-current, over-voltage and over-temperature events.
