Pure Power 13 M 850W ATX 3.1 PSU

This power supply delivers 850 W of continuous output for high-end desktop builds. It meets the ATX 3.1 specification and includes a PCIe 5.1 12V-2x6 connector rated for 600 W. The unit is designed for gamers and creators who need stable power for modern graphics cards.

Modular design with four PCIe 6+2 cables

A fully modular cable set lets builders attach only the leads they need, reducing clutter inside the case. Four PCIe 6+2 connectors support additional GPUs or power-hungry add-in cards. Six SATA connectors handle multiple drives, while two legacy PATA plugs remain for older peripherals.

Semi-passive 120 mm fan under sustained load

The temperature-controlled 120 mm fan stays idle at low power draw and spins up only when internal temperatures rise. LLC resonant topology and a single 12 V rail keep voltage regulation tight during extended gaming or rendering sessions. 80 PLUS Gold certification at up to 94.4 % efficiency limits waste heat, helping the fan run slower for longer periods.

Questions about this item

At what load does the 12 V rail hit its 850 W limit during sustained operation?

The single 12 V rail is rated for 850 W continuous output, so the limit is reached when total system draw approaches that figure.

How loud and hot does the 120 mm fan run in semi-passive mode after hours of full load?

The fan stays off at low load and spins up only when needed, keeping noise and temperature low even during extended high-load sessions.

Which GPU power cables must my graphics card already support to use the 600 W 12V-2x6 connector?

Your GPU needs a native 12V-2x6 or 12VHPWR input; the PSU also includes four 6+2 pin PCIe connectors for cards that still use them.
