Corsair launches its first PSU with ThermalProtect 12V-2×6 cables

Corsair has officially released its new RM1000E power supply, promising users “better cables and cable management” through its use of “ultra-flexible debossed cables”. This PSU also features ThermalProtect, using a specialised 12V-2×6 cable that can prevent cable melting incidents before damage can occur. ThermalProtect is a patent-pending Corsair technology.

The new RM1000E is available in black and white, with both models achieving Cybenetics Platinum-certified efficiency levels. This PSU is fully modular and features a zero-RPM fan mode under low-power loads.

– includes Thermal Protect 12V-2×6 cable
– ATX 3.1 certified and PCIe 5.1 compliant

How does Corsair ThermalProtect work?

Corsair’s new PSU cable is rated for 600W and uses flexible debossed cables with low-profile cable combs. These cables are backed by a two-year warranty and are available in black and white.

Once Corsair’s Over Temperature Protection (OTP) tech activates, users need to shut down their PCs and allow their 12V-2×6 cable to cool down. Once their cables have cooled, users should check for damage and reseat them. Users should ensure that their cables are pressed in correctly. There should be an audible click when your cable’s retention connector clamps down. Additionally, users should not be able to see the grey power connectors on Corsair’s 12V-2×6 cables.

Corsair’s OTP tech activates if temperatures exceed 65 degrees. Corsair’s detection hardware is located 30mm from the GPU connection. Corsair claims that this tech can shut down GPUs in “milliseconds”.

Corsair’s new RM1000E PSU is available now. Additionally, a new 850W version of this PSU is also available. Both models are available now from Corsair’s website. Furthermore, Corsair’s new ThermalProtect PCIe 5.1 (12V-2×6) cables are also available standalone from Corsair’s website for £14.99.
