The Raidmax XTB-Series 650W Non-Modular PSU is a great entry-level power supply. It utilises a single +12V rail output for enhanced stability. This power supply is designed with heavy-duty protective technologies, namely Over Voltage Protection (OVP), Over Power Protection (OPP) and Short Circuit Protection (SCP). Raidmax has designed the XTB-Series with optimal heat dissipation via a honeycomb ventilation grid and a silent 120mm fan that automatically adjusts speeds based on thermal status.
