G12-GC-650

SSP-650RT2

Reliable 650W power supply with 80+ Gold certification, guaranteeing at least 87%, 90% and 87% energy efficiency of the device at 20%, 50% and 100% workloads respectively. Note that this is one of the junior models in Seasonic's G12 family, which also includes 550W, 750W and 850W modifications. It is positioned by the manufacturer as a product of the middle price category of the 2021 sample, designed to power high-performance gaming systems and powerful workstations with demanding professional graphics accelerators.

The Seasonic G12-GC-650 power supply uses an LLC resonant converter design and an intelligent fan control (S2FC) system that strikes a balance between noise and cooling. It also guarantees excellent stabilization of output voltages and the ability to deliver up to 648 W of power along the +12 V line (current up to 54 A). To cool the heating components of the device, a controlled 120 mm fan with an impeller is used, the shape of which is optimized for efficient and quiet operation at low speeds. But the wire system of this model is not modular, but all the wires are braided.

wonderful model, really honored
11 December 2024 
I have been using this power supply for about six months. I am completely satisfied. There are enough cables for connection with a surplus. It is quiet. There are protection technologies present, which are very relevant in today's power outages. The cables are made of high quality and even without braiding they look great. I recommend it.
Quiet, all protections are present, cable reserve
nothing
