ATX 3.1 power supply

The Raidmax Cobra delivers 750 W through a single +12 V rail and meets the ATX 12V v3.1 standard. It carries 80 PLUS Gold certification with typical efficiency above 90 percent. A 120 mm fan provides cooling while flat black cables help keep the interior tidy.

Gaming and content-creation builds

This unit suits systems that need PCIe Gen 5 power connections and a full set of protections including OVP, UVP, OCP, SCP and OTP. Builders who require fully modular cabling or a higher wattage ceiling should consider other models.

Fixed-cable design

All cables are permanently attached, so the 20+4 pin main connector, two 6+2 pin PCIe leads and six SATA plugs cannot be removed. Verify that your case and routing preferences accept a non-modular layout before purchasing.

Questions about this item

At what load does the 750 W unit hit its efficiency peak under sustained use?

The 80 PLUS Gold rating guarantees over 90 percent efficiency at typical loads, so sustained output near 50 percent of the 750 W maximum is where the unit runs most efficiently.

How loud and hot does the 120 mm fan get when the PSU runs all day at high load?

The low-noise 120 mm fan uses advanced thermal control to keep noise down and dissipate heat efficiently even during extended high-load sessions.

Which power cables must my build already provide for the fixed flat-cable loom to connect?

The non-modular loom includes a 20+4 pin main connector, two 6+2 pin PCIe connectors and six SATA power connectors, so your motherboard, graphics card and drives must accept those plugs.
