Incorporating various high-quality components, the new Litepower Series – rated from 350W to 650W – saves energy through its high efficiency up to 85% and accommodates any build with the most demanding requirements. An embedded intelligent cooling fan delivers excellent airflow at an exceptionally low noise level. In addition, the single +12V rail design enables non-stop usage with stable and reliable performance. Litepower Series adopts 120mm cooling fan delivers excellent airflow at an exceptionally low noise level. Users are able to properly route the cables in optimal location to prevent airflow blockage. Extra-long EPS/ATX 12V 4+4pin CPU cable (550mm) guarantees sufficient lengths of cables to the build, especially full-tower chassis. Sleeved 24pin cable makes cable management easier, reducing clutter and increasing airflow inside the chassis. Its High quality components enable non-stop usage with stable and reliable performance, no more capacitor explosion and leakage. Litepower Series is equipped with powerful +12V rails.
