850 W ATX 3.1 power supply

The SAMA XPH850-AP delivers 850 W of continuous power in an ATX 3.1 compatible design. It meets Cybenetics Platinum standards with efficiency above 92 percent under typical loads. The unit targets builders who need stable output for modern graphics cards and processors.

Fully modular with 12V-2x6 connector

A native 12V-2x6 PCIe 5.1 connector supplies up to 600 W without adapters. Fully modular cabling reduces clutter and improves airflow in compact cases. The 140 mm FDB fan stops below 60 percent load or 55 °C for silent operation. Compact 150 mm depth eases installation in smaller chassis.

Suits high-performance PCs

Builders seeking Platinum efficiency, native PCIe 5.1 readiness and a 10-year warranty will find this unit a strong match. Systems that require multiple 6+2-pin PCIe cables or more than two SATA power connectors should consider alternatives.

Questions about this item

How long can the 850W output hold up during a full-load spike?

The hold-up time is greater than 16 ms at 100% load, giving the system a brief buffer before shutdown.

Does the 140 mm FDB fan stay on all day under typical loads?

The fan stops completely below 60% load or 55°C, so it stays off during light work and spins quietly when needed.

Which connector must my graphics card have to use the native 600W PCIe 5.1 link?

The card needs a 12V-2x6 (12VHPWR) socket; the supply includes that 16-pin cable so no adapter is required.
