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.

Offers cable selection for users while powering the system at an advantageous voltage. Low-profile flat white cable makes cable management easier, reduces clutter and increases airflow inside the chassis.

Toughpower GF3 ARGB series is fully compatible with Intel ATX 3.0 Specifications which supports up to 200% power excursion, reaches 70% low load efficiency, and complies with required power supply timing standards. With a final shot of the GF3 ARGB 850w installed inside the case with the RGB effect on display. It’s great to see bright LEDs with great clarity on offer, even on a PSU.

Hold Up Time

Probably youre right. Mine has cutoff mechanism inside, i can barely hear that something cutting off the power, but you cant control it. Toughpower GF3 Snow comes with a 12+4-pin connector to offer powerful and stable performance allowing the PSU to run next-generation GPUs naturally. 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.Probably both use the same PCB, both are CWT production. I couldn't trust it and then returned it because I was going to use it as a rendering and workstation. Top-end build quality with low ripple noise. GF3 1200 W Snow's all ripples are lower than 30 mV on +12V, +5V or +3.3V from 0% to 100% load to ensure a stable operation and keep your performance-critical components to function reliably for longer. I had an issue during ATX v3.0 transient testing for PSUs equipped with 12VHPWR connectors, so you won’t find these tests in the review. I have informed TT to send me a second sample to run the tests, and I will update the review once I have all the data. The lower capacity GF3 models, 750W and 850W, passed the corresponding tests successfully, but things will be tougher for the 1200W model since it will have to go up to 2400W for the 0.1ms transient response test! Given that the highest power spikes I measured in a low-end RTX 4090, by Palit, were 700W, there is no need for the PSU to be able to handle such high power spikes, so the GF3 1200W won’t have an issue with any RTX 4090, even if you push the power limit up to 600W. Still, NVIDIA will raise the bar even higher, asking PSU manufacturers to tune their platforms for up to 235% power spikes! Either NVIDIA knows something that I don’t, or it just prepares the ground for the next generation of GPUs. Either way, 200% power spikes were crazy already, and now the bar will go even higher!

High-quality Japanese 105°C/221°F main electrolytic capacitors offer stability and reliability which enhance the durability of the GF A3 Gold series. Electrolytic: 3x Nichicon (2-5,000h @ 105°C, HD), 4x Nichicon (4-10,000h @ 105°C, HE), 1x Rubycon (2-10,000h @ 105°C, YXF), 1x Nippon Chemi-Con (4-10,000h @ 105°C, KY), 1x Nippon Chemi-Con (4-10,000h @ 105°C, KYA) Since we don’t currently have access to an ATX load tester, a multimeter shows the PSU performance on the +3.3v, +5v, and +12v rails. Although we can’t do complete load tests, we can provide relative information regarding variance and fluctuation of current and ripple on the rails, which is integral and indicative of the quality of a power supply. Toughpower GF3 Snow series is fully compatible with Intel ATX 3.0 Specifications which supports up to 200% power excursion, reaches 60% low load efficiency and complies with required power supply timing standards. The GF3 Snow series can sustain up to 3x GPU power excursion and 2x total power excursion.
