SAPPHIRE NITRO+ Radeon™ RX 580 8GD5 Special Edition(METAL BLUE)

Fuse protection
In order to protect your card, the SAPPHIRE NITRO+ series cards have fuse protection built into the circuit of the external PCI-E power connector to keep the components safe.

Precision fan control
Standard industry fans may have up to 10% difference between their fan rotation cycles (RPM). With the new Fan IC Control on SAPPHIRE NITRO + graphics cards, this differential is reduced to 3%. This 70% improvement on accuracy ensures that cooling and noise performance of every NITRO + card is up to scratch.

Black Diamond Choke 4
Our Black Diamond Chokes are 10% cooler and 25% more power efficient than a normal choke - and these Mark 4 Chokes reduce the coil temperatures by other 15% over the Mark 3s. These exclusive chokes will maintain gaming stability using their built-in heatsinks and help minimize coil whine

Dual Ball Bearing - 1.85X longer life
Dual ball bearings on the fan spindles ensure smooth running and long life and are designed to keep out dust. A quiet cooling solution, Two ball-bearing fan features a high-efficiency blade design.

Nitro Glow 2
The graphics card is more than another component; it’s the beating heart of your gaming system. It should look as good as it costs. With tasteful shroud design augmented by RGB LEDs, each card is practically a piece of art. You can even change the colours of the LED, for your own customized design. This can be controlled via software using the latest version of SAPPHIRE’s Award Winning Overclocking Utility – TriXX 3.0. Users can choose from a set of five different modes including Fan Speed Mode, PCB Temperature Mode or the colourful rainbow mode. If you prefer, LEDs can also be turned off.
