ASUS Prime 650B 80+ Bronze Non Modular ATX 2.0 Power Supply ( 650W )

The ASUS Prime 650B is a 650-watt non-modular ATX power supply designed for reliable, efficient desktop PC builds. Carrying an 80 Plus Bronze certification, it delivers improved energy efficiency over uncertified units, thanks in part to low-ESR electrolytic capacitors and Active Power Factor Correction (Active PFC). The unit meets the ATX12V form factor standard and is compatible with a wide range of mid-tower and full-tower cases. Cooling is handled by a 135 mm fan mounted on dual ball bearings. According to ASUS, dual ball bearing designs offer an operational lifespan of up to 80,000 hours — approximately twice that of traditional sleeve bearing fans — contributing to long-term thermal stability and quieter acoustics over time. The pre-attached cable set includes one 24/20-pin motherboard connector, one 4+4-pin CPU connector, two PCI-E 8-pin (6+2) connectors for discrete graphics cards, five SATA connectors for storage devices, and three 4-pin peripheral connectors for legacy drives and accessories. Cables are constructed from an etched, pliable material that ASUS states meets UL1581 flame-test and UL758 certification requirements, making routing and cable management more manageable during installation. The CPU power cable features a color-differentiated 4+4-pin connector with an integrated locking clip, intended to simplify identification and ensure a secure seat on the motherboard header. Protection circuitry covers Over Power Protection (OPP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Short Circuit Protection (SCP), Over Current Protection (OCP), and Over Temperature Protection (OTP). The unit accepts a universal AC input range of 100–240 V, making it suitable across different regional mains standards. RoHS compliance is confirmed by the manufacturer.
