The HyperX Pulsefire Haste 2 is built for gamers who maximize every millisecond. Our designers optimized the original Pulsefire Haste to deliver a solid-shell sequel that performs brilliantly, but weighs just 53g3. Then our team built a high-performance HyperX suite of components, highlighted by the precision HyperX 26K Sensor which has a native DPI of up to 26,000 with a tracking speed of up to 650 IPS.
