Platinum 850 W ATX 3.1 unit

The Montech TITAN PLA 850 is a fully modular ATX 3.1 power supply rated at 850 W. It carries 80 PLUS Platinum and Cybenetics Platinum certifications for 90 % efficiency. A 135 mm FDB fan runs in zero-fan mode below 20 % load. The unit is built in collaboration with Seasonic.

ATX 3.1 and PCIe 5.1 limits

The supply meets ATX 3.1 and PCIe 5.1 specifications and includes a native 12V-2x6 connector. Peak power can reach twice the rated 850 W. GPU peak support is rated at three times the graphics card wattage. Hold-up time exceeds 21 ms. Input range is 100 to 240 V at 50 or 60 Hz.

Check cables and clearances

Verify your motherboard needs one 20+4 pin and two CPU 4+4 pin connectors. Ensure the graphics card can use the single 12V-2x6 or three PCIe 6+2 pin plugs. Confirm the 160 mm depth fits your case. Count SATA and Molex devices against twelve SATA and four Molex headers.
