ATX 3.1 PCIe 5.1 750W PSU

The Montech Century II 750W is an ATX 3.1 power supply with PCIe 5.1 support and a native 12V-2x6 cable. It delivers 750 W through a fully modular design and carries 80 Plus Gold certification. Japanese capacitors and an LLC plus DC-to-DC topology provide stable voltage under load.

Suits new builds with 12V-2x6 GPUs

Builders assembling systems around current-generation graphics cards will appreciate the native connector and Gold efficiency. The fully modular flat cables simplify cable management in compact cases. Users staying with older 8-pin GPUs or needing higher wattage should evaluate other units.

12V-2x6 cable decides compatibility

The included 12V-2x6 cable is the single specification that determines whether this unit fits a modern GPU without adapters. If the target graphics card requires that connector, the PSU is ready; if the card uses legacy 8-pin power, the cable will remain unused.

Questions about this item

What motherboard power connector does the Century II 750W require?

The unit supplies a 20+4Pin main connector that plugs directly into any standard ATX motherboard socket.

Will the included 12V-2x6 cable work with an older graphics card that uses 8-pin PCIe power?

The 12V-2x6 cable is built for PCIe 5.1 devices; older 8-pin cards need the appropriate PCIe 6+2 cables that come in the modular set.

How can I confirm the 135mm FDB fan is running in zero-RPM mode at low load?

With the system idle the fan should stay completely still; you can verify by watching the blades or listening for silence while the PSU powers the PC.
