ATX 3.1 power supply for modern builds

The Raidmax Cobra delivers 650 W through an ATX 12V v3.1 design with 80 PLUS Gold certified efficiency. A single +12 V rail supplies stable power to demanding components. Black flat cables reduce clutter and improve airflow inside the case.

Who this suits and who should look elsewhere

Builders assembling a gaming PC or workstation with a current-gen graphics card will appreciate the PCIe Gen 5 readiness and full protection suite. Systems requiring modular cabling or higher wattage for multi-GPU arrays should consider a different unit.

The specification that decides fit

Two 6+2 pin PCI-Express connectors provide the only native GPU power outputs on this non-modular unit. Verify that your graphics card draws no more than two such connectors before choosing this supply.

Questions about this item

Will the 650 W output handle a modern GPU that needs a 12VHPWR connector?

This unit provides two 6+2-pin PCIe cables but no native 12VHPWR plug; an adapter is required for cards using that connector.

Are the cables detachable for a cleaner build?

The power supply is non-modular, so all cables are fixed and cannot be removed.

What protections guard my components against faults?

It includes OVP, UVP, OCP, SCP, OPP and OTP to shut down safely on over-voltage, under-voltage, over-current, short-circuit, over-power or over-temperature events.
