Thermaltake Toughpower GF A3 750W Power Supply Unit Evaluation: Delivers Solid Mid-Tier Performance and Modern I/O Connections
The Thermaltake Toughpower GF A3 750W power supply unit is making waves in the PC building community, earning praise for its efficiency, noise levels, and value. This PSU, housed in a sturdy cardboard box and boasting a sleek, understated design, offers a compelling set of features for its price point.
Manufactured by Great Wall, the internal layout of the Toughpower GF A3 750W reveals a clean and well-organized design. The unit adheres to the standard ATX form factor, measuring 140mm in depth, and boasts a 12VHPWR connector that provides ample power for NVIDIA's RTX 40 series GPUs, including the RTX 4090. The PSU's features include a fully modular design for easy cable management, with cables predominantly made of flat and ribbon-like materials.
The Toughpower GF A3 750W's efficiency is a standout feature, with the Toughpower GF A3 series, including the 750W model, being 80 PLUS Gold certified. This certification indicates high efficiency typically around 87%-90% at typical loads. The PSU performs well in efficiency tests and is often regarded as a good performer at 230V and 115V input voltages. Some reviews note that it offers good overall efficiency at a competitive price, contributing to its appeal in the mid-range PSU market.
Users and reviewers consistently praise the power supply for being quiet during operation, even under load. Testimonials from users mention the PSU as virtually silent, especially in quiet mode, making it suitable for builds where low noise is a priority. The PSU's cooling performance is impressive, thanks to its efficient internal design and 120mm FDB fan.
While one professional review pointed out an unusual ripple voltage increase between 40-90% load, with a spike over 40mV on the 12V rail for a specific sample tested, this appears to be an outlier or sample-specific issue rather than a widespread problem. The overall advice from experts is that this anomaly is not generally a cause for concern and should not necessitate replacing the unit—long-term reliability is still expected to be good.
The Toughpower GF A3 750W is seen as good value for the money, offering modern features like PCIe Gen 5 readiness and full modularity. Compared to other 750W PSUs, it rates well for ripple suppression and provides solid transient response performance. It balances good efficiency, quiet operation, and a reasonable price, making it a competitive choice in its segment.
