A 12+4-pin connector is included with the Toughpower GF A3 Snow series to provide powerful and stable performance that enables the PSU to run next-generation GPUs natively. Toughpower GF A3 Gold series is completely compatible with Intel ATX 3.0 Specifications which supports up to 200% power excursion, achieves 60% low load efficiency, and meets required power supply timing standards.
The cables are delivered in a canvas bag. The lid is lined with velcro, so it can be used to store and seal the cables you don’t need safely and securely. To satisfy the increasing demand for the power consumption of graphics cards, the GF A3 Gold Snow series is designed to support NVIDIA and AMD graphics cards and is able to supply the graphics cards in different ways of connection.To satisfy the increasing demand for the power consumption of graphics cards, the GF A3 Gold series is designed to support NVIDIA and AMD graphics cards and is able to supply the graphics cards in different ways of connection. Put simply, whatever you fancy or whatever your hardware requires, there’s something for everyone here in the ToughPower GF3 series when it comes to power output. And let me make the point as well that it’s more than a little unusual to see six variants in any power supply series. Thermaltake definitely seems to be appealing to the masses with this one!
Probably youre right. Mine has cutoff mechanism inside, i can barely hear that something cutting off the power, but you cant control it. To prevent momentarily drops and transient power outages caused by a power interruption, the GF A3 series will deliver at least 17 ms at 100% workload, without system reboot or resetting. Also to anyone else following earlier posts of mine in this thread. The Hela 1200r sent a new production unit to Cybenetics and it has now passed atx 3.0 certification. Apparently they had sent a pre production unit first and that’s why it failed one of the transient load tests.

Featuring a 120 mm fluid bearing fan to deliver excellent airflow. Furthermore, the Smart Zero Fan will the fan will not spin until the load exceeds 30% of the power supply, minimizing undesired noise. Thermaltake, the leading PC DIY premium brand for Case, Cooling, Gaming peripherals, and enthusiast memory solutions, is excited to introduce the latest Toughpower GF A3 Gold series. Designed with Intel ATX 3.0 compliance, a native PCIe Gen 5.0 12+4pin modular interface, and 80 PLUS Gold efficiency, the Toughpower GF A3 is ready to fully support the newest-gen hardware. This PSU comes with the dimensions of 150 mm (W) x 86 mm (H) x 140 mm (D), and it has five watts to choose from, including 1200 W, 1050 W, 850 W, 750 W, and 650 W. Additionally, the Toughpower GF A3 Gold series meets Intel voltage regulation standards, which strengthens power stability and reliability. Toughpower GF3 Snow series saves energy through its high energy efficiency up to 90% and is certified to 80 Plus Gold. The series has been optimized to work with all generations of Intel's processors to achieve maximum energy saving. PCIe Gen 5.0 Ready! Designed with a native PCIe 12+4pin modular connector, the Toughpower GF3 series is built for the next-gen PCIe 5.0 graphics cards and is compatible with Intel ATX 3.0 specifications. The fully modular Toughpower GF3 series comes in 1650W, 1350W, 1200W, 1000W, 850W and 750W and is built to deliver 80 PLUS Gold efficiency. Aimed at providing the best performance, the Toughpower GF3 1350W includes all the critical features such as < 30mV low ripple noise design, extremely strict voltage regulation < ±3%, hold up time> 17 milliseconds, and comes with 100% high quality Japanese capacitors and other premium components to help deliver continuous and stable power.” Features On the rear side, we can see the power switch, a cover over the 3-pin plug that explains the second on/off switch, which is the switch for the “smart zero fan.” Below, we have a “mode” and “color” switch which controls the ARGB LEDs should you not want to connect them to the motherboard ARGB connectors. Turning this on enables a mode where the fan doesn’t turn on until it’s under load—keeping the unit as quiet as possible.
To ensure stability, the GF A3 Snow is made with single +12V rails for delivering power to reach the best compatibility, as well as designed with the LLC and DC to DC circuit for strengthening the voltage regulation. Voltages will be monitored via a multimeter, and the AC power draw will be monitored via a power monitor when drawn from the wall. For the idle test, the system will be simply booted up and let run into Windows 11, and after 5 minutes, the readings will be taken when the power draw has leveled out. It features a 140mm fluid dynamic bearing fan to balance silence and superior cooling perfectly. Furthermore, the Smart Zero Fan will not spin until it reaches a specific temperature, minimizing the fan noise. Electrolytic: 5x Rubycon (3-6,000h @ 105°C, YXG), 1x Nichicon (4-10,000h @ 105°C, HE), 2x Rubycon (6-10,000h @ 105°C, ZLH), 2x Rubycon (4-10,000h @ 105°C, YXJ)

The GF3 1200W is the highest capacity model of this line, based on a CWT platform. The GF3 1350 and 1650 use a platform provided by High Power, so the design is completely different. Even the modular cables are not electrically compatible. I tried to switch the cables to run EMI tests, and the GF3 1350 I was currently testing politely refused to start since its supervisor IC sensed a short. Thank you to Thermaltake for sending the TOUGHPOWER GF3 ARGB 850w unit for today’s review! Related Reading: Oct 16th 2023 Thermaltake Unveils Its First Ever Bumblebee-Colored Product in The Tower 200 Mini Chassis Series (19) The Thermaltake ToughPower GF3 is available in a wide variety of wattage outputs to suit practically all needs and requirements. These include: For optimal energy savings, the GF A3 series has been designed to work with all Intel processor generations to operate power efficiently.
High-quality Japanese 105°C/221°F main electrolytic capacitors offer stability and reliability which enhance the durability of the GF A3 Gold series. Hahah, I have been watching certain pc parts that way for the last couple months, but as far as PSU's go. I just did a few hours of research and things are very confusing with all the conflicting info you find. The Smart Zero Fan inside the Toughpower GF A3 Gold series produces excellent airflow with an incredibly quiet 120 mm fluid bearing fan, as well as the ability to minimize undesired noise. Designed with our Smart Zero Fan, the fan only spins until the load reaches a certain percentage of the power supply, and the users can turn it on and off by its physical switch. To achieve the power efficiency of the PC system and the eco design, the Toughpower GF A3 Gold series supports Intel deep power down C6/C7 status. To fully support next-gen hardware, Toughpower GF A3 Gold Series (650 W/750 W/850 W/1050 W/1200 W) complies with ATX 3.0 standards, including a PCIe Gen 5.0 12VHPWR connector.It’s also great to see Thermaltake keeping up with the latest specifications, as this GF3 ARGB 850w unit utilizes the latest Intel 3.0 ATX specification and PCIe Gen 5.0 GPU power connector. Toughpower GF A3 Gold Snow series is completely compatible with Intel ATX 3.0 Specifications which supports up to 200% power excursion, achieves 60% low load efficiency, and meets required power supply timing standards. The fully modular low-profile white cables make cable management easier and more flexible, increasing the tidiness and airflow inside the chassis. Thermaltake is undoubtedly a highly respected manufacturer of PC hardware, peripherals, and components. And especially so when it comes to their power supply designs.
