EVGA vs Thermaltake PSU Specs
efficiency rating
Efficiency determines how much electricity converts to usable power versus waste heat. The EVGA SuperNOVA 750W achieves 80PLUS Bronze certification, reaching up to 85% efficiency under typical loads. This is a solid baseline for general computing tasks. In contrast, the Thermaltake Toughpower Grand 850W holds an 80PLUS Gold certification. It delivers higher efficiency, ranging from 87% to 93% across 20% to 100% loads. Higher efficiency means less energy wasted as heat and potentially lower electricity costs over time. Gold certification is generally preferred for systems that run frequently or under heavy loads. The Thermaltake unit offers a clear advantage in energy conversion performance.
wattage output
Wattage indicates the maximum power the supply can deliver to your components. The EVGA SuperNOVA NEX750B provides 750W of continuous power. This is sufficient for many mid-range gaming rigs and workstations. The Thermaltake Toughpower Grand 850W offers 850W of continuous output. It is also guaranteed to deliver this full 850W continuously at 50°C ambient temperature. This thermal headroom ensures stable performance even in warm cases or under sustained stress. The 100W difference gives the Thermaltake unit more headroom for high-end GPUs or future upgrades. If you plan to push components to their limits, the extra wattage matters.
modularity type
Modularity affects cable management and airflow inside your case. The EVGA SuperNOVA 750B uses a hybrid modular design. This means the main ATX and CPU cables are fixed, while peripheral cables can be detached. This reduces clutter compared to non-modular units but still leaves some cables in the way. The Thermaltake Toughpower Grand is fully modular. Every cable can be disconnected from the unit. This allows for the cleanest possible cable routing and maximizes airflow. Full modularity is ideal for tight cases or builds where aesthetics matter. The EVGA approach is a compromise, while Thermaltake offers complete flexibility.
fan specifications
Fan design influences noise levels and thermal management. The EVGA SuperNOVA uses a quiet 2-ball bearing fan. It is designed for near-silent operation, which is good for quiet builds. The Thermaltake Toughpower Grand features a proprietary 14cm flower-shape fan with dual ball bearings. The larger 14cm size allows the fan to move more air at lower RPMs, which typically reduces noise. It also claims longer lifespan due to reduced bearing friction. The larger fan diameter is generally preferred for better acoustics and airflow efficiency. The EVGA fan is standard size, while Thermaltake uses a larger, potentially quieter solution.
physical dimensions
Size determines compatibility with your case. The EVGA SuperNOVA 750B measures 7.1 inches in length, 5.9 inches in width, and 3.4 inches in height. It weighs 7 pounds. These are standard ATX dimensions that fit most mid-tower and full-tower cases. The Thermaltake Toughpower Grand 850W is significantly larger, measuring 13.3 inches in length, 8.27 inches in width, and 6.18 inches in height. It weighs 6 pounds. The extreme length and width may not fit in smaller cases or standard PSU shrouds. You must verify your case dimensions carefully before choosing the Thermaltake unit. The EVGA offers standard fitment with no compatibility worries.
Which PSU fits your build needs
General desktop users seeking balance
The EVGA SuperNOVA NEX750B delivers 750W with 80PLUS Bronze efficiency. Its hybrid modular design reduces cable clutter while improving airflow. Japanese capacitors ensure long-term reliability. This unit offers a quiet operation suitable for standard computing tasks without excess power or cost.
High performance and mining builds
The Thermaltake Toughpower Grand provides 850W with 80 PLUS Gold efficiency. It guarantees continuous power at 50°C for 24/7 operation. Fully modular cables keep your case tidy. The 14cm fan reduces noise, while 105°C Japanese capacitors handle harsh environments with stability.
Users prioritizing pure efficiency
Thermaltake achieves 87-93% efficiency at various loads, surpassing the EVGA Bronze rating. This Gold certification minimizes wasted electricity as heat. The higher wattage headroom supports demanding components. You get better energy conversion and lower operational heat, which helps maintain cooler internal temperatures.
