Thermaltake, a well-known company among enthusiasts, said Tuesday its first power supply unit for graphics cards had been certified by Nvidia Corp. as “SLI ready”. Dedicated power supply units (PSUs) for graphics cards allow users with moderate PSUs to take advantage of high-performance graphics cards and multi-GPU technologies.

Thermaltake’s Purepower Power Express 250W provides two +12V rails to graphics cards with 21A current. The power supply is equipped with OVP, OCP, SCP, OTP, and other kinds of circuitry protection as well as active PFC. Additionally, the PSU features 40mm fan for more stable operation. The device is designed for integration into 5.25” bay.

The Power Express 250W is also equipped with a 24-pin main adaptors so that the unit can turn on and off at the same time the computer system is being turned on and off. The simple 5.25” drive bay is powered through an AC adaptor card in one of the PCI slots; this implementation of the unit enables easy access and easy installation of the whole system, believes Thermaltake.

“Power Express 250 just passed Nvidia’s qualification and officially become ‘The world’s first NvidiaCertified SLI-dedicated graphics card power supply’,” a statement by the company reads.

Earlier FSP has unveiled its PSU for graphics cards as well.
