Know before you buy
Yes, the Toughpower GF A3 includes a native PCIe Gen 5.0 12VHPWR connector, allowing you to power modern high-end graphics cards directly without needing bulky adapters.
The Smart Zero Fan mode keeps the 135mm cooling fan completely off when the power supply is under 40% load. This ensures silent operation during light tasks like web browsing or document editing.
Yes, it is fully modular, meaning every cable can be detached from the power supply. This allows you to use only the cables you need, which significantly reduces clutter and improves airflow inside your case.
With a depth of only 140mm, this unit is quite compact for an 850W power supply. It should fit comfortably in most standard ATX cases, though you should always double-check your specific case's clearance requirements.
ATX 3.0 certification ensures the power supply can handle the transient power spikes common with next-generation hardware. It provides better stability and safety for modern, high-performance components.
The unit comes with low-profile flat cables that are much easier to route behind your motherboard tray compared to traditional rounded, sleeved cables. This makes cable management cleaner and more straightforward.
