The most recent Toughpower GF A3 Gold series is being unveiled by Thermaltake with excitement. The Toughpower GF A3 is equipped with native PCIe Gen 5.0 12+4pin modular interface, Intel ATX 3.0 compliance, and 80 PLUS Gold efficiency to accommodate the most recent generation of hardware.

Its dimensions are 150mm (W) x 86mm (H) x 140mm (D), and it offers five wattage options: 1200W, 1050W, 850W, 750W, and 650W. The Toughpower GF A3 Gold series also complies with Intel’s voltage control regulations, improving power stability and dependability.

Thermaltake TOUGHPOWER GF A3 Gold 1050W Unboxing & First Impressions

The package of the Thermaltake TOUGHPOWER GF A3 Gold 1050W initially caught my attention when it arrived. The box had a modern appearance and included information about the features, specs, and a good picture of the power supply. The power supply was safely tucked within the box, cushioned by foam to keep it safe while being transported.

The power supply itself made a good first impression. The Thermaltake TOUGHPOWER GF A3 Gold 1050W has a solid build, a 140mm bottom-mounted fan, and a black powder-coated finish. The all-black aesthetic emits a polished and professional vibe that would go well with most PC settings.

Thermaltake TOUGHPOWER GF A3 Gold 1050W Features & Connectivity

The Thermaltake TOUGHPOWER GF A3 Gold 1050W is a versatile option for a variety of system settings because to its broad feature set. It has a variety of connections, including two 8-pin (4+4) CPU connectors, two 4-pin (4+4) peripheral connectors, ten SATA connectors, eight PCIe connectors (6+2), and eight 24-pin ATX connectors, allowing for enough connectivity for several components.

The modular architecture of this power supply is one of its distinguishing qualities. Cable management is simplified with the detachable cords, which also improve interior ventilation and lessen case clutter. This is especially useful for those that place a high value on having a tidy home, which is necessary for effective system cooling.

The Toughpower GF A3 Gold series’ Smart Zero Fan minimizes unwanted noise while producing great airflow with a 120mm fluid bearing fan that is exceptionally quiet. The fan is controlled by a physical switch and is designed with our Smart Zero Fan so that it only spins when the load reaches a specific percentage of the power supply. 

The Toughpower GF A3 Gold series is 80 PLUS Gold certified and complies with Intel ATX 3.0 and voltage regulation requirements. If you need a high-quality completely modular PSU to handle next-generation graphics cards but are constrained by your chassis dimensions, don’t overlook the Toughpower GF A3 Gold series.

Intel voltage regulation requirements are adhered to in the design of the Toughpower GF A3 Gold series, providing improved power stability and dependability. Your GPU will receive consistent power thanks to its Intel ATX 3.0 standard, which supports a 200% power excursion and a 60% low load efficiency.

The most recent, top-tier graphics cards may be powered by a single cable using the native PCIe Gen 5.0 12VHPWR connection. The Toughpower GF A3 Gold series also has better Japanese primary electrolytic capacitors rated at 105°C/221°F, a high amperage single +12V rail, and a DC to DC architecture that promotes robustness, stability, and compatibility.

Thermaltake TOUGHPOWER GF A3 Gold 1050W Performance 

Performance-wise, the Thermaltake TOUGHPOWER GF A3 Gold 1050W lives up to expectations.  It offers a steady and continuous power output, guaranteeing a smooth system operation even with high loads. The power supply has a single +12V rail configuration that works well with modern CPUs and graphics cards and is excellent for high-performance systems.

The 140mm Fluid Dynamic Bearing (FDB) fan’s construction is meant to be silent while still providing enough cooling. During testing, the fan was almost completely quiet under light loads and only made a little hum when the system was put under a lot of strain. Because of this, it’s a great option for people that appreciate a quiet computing environment.

The GF A3 Gold 1050W is 80 PLUS Gold certified, which corresponds to at least 87% efficiency at 20% load, 90% efficiency at 50% load, and 87% efficiency at 100% load. This high efficiency increases component longevity and promotes greener computing by lowering heat output while simultaneously reducing energy use.

The capacity of a power supply to sustain consistent voltage output across all rails is among its most important features. With its outstanding voltage control, the Thermaltake TOUGHPOWER GF A3 Gold 1050W makes sure that vital components get a stable and dependable power supply.

Even under conditions of full load, the power supply showed little voltage fluctuation throughout our tests. Better system stability and a lower chance of hardware damage from voltage spikes or drops result from this. This power supply is capable of handling resource-intensive rendering jobs as well as lengthy gaming sessions.
