Thermaltake vs Segotep PSU Specs
wattage output
The Thermaltake Toughpower Grand delivers 850W of continuous power, while the Segotep unit provides 650W. This 200W difference is significant for your system’s headroom. If you plan to run high-end graphics cards or multiple drives, the Thermaltake offers more reserve capacity. The Segotep’s 650W is sufficient for mid-range builds but leaves less room for future upgrades. You should choose the higher wattage if your components demand more steady current under heavy loads.
modularity
Cable management affects airflow and case aesthetics. The Thermaltake is fully modular, meaning you only connect the cables your system actually uses. This reduces clutter and improves air circulation. The Segotep is non-modular, so all cables are permanently attached. You must route every cable, even those you do not use, which can obstruct airflow. For a clean build, the Thermaltake’s design is superior. The Segotep’s fixed cables are simpler but less flexible for tight cases.
efficiency rating
Both power supplies hold the 80 PLUS Gold certification. This rating indicates high efficiency across a wide load range. The Thermaltake specifies 87-93% efficiency at 20-100% load. The Segotep also boasts Gold certification for exceptional efficiency. Neither unit offers a higher tier like Platinum or Titanium. Since both share this standard, you will see similar energy savings and heat generation. This aspect results in a tie for your decision.
fan size
Cooling hardware differs between the two units. The Thermaltake uses a 14cm flower-shape fan with dual ball bearings. Larger fans typically spin slower to move the same amount of air, potentially reducing noise. The Segotep uses a 120mm fan. While 120mm is standard, the Thermaltake’s larger 14cm diameter may offer quieter operation at low loads. Both fans are designed for reliability, but the Thermaltake’s bearing type and size suggest a focus on longevity and noise reduction.
atx version
Standards compliance ensures compatibility with modern motherboards. The Thermaltake complies with ATX 12V 2.3 and SSI EPS 12V 2.92. These are specific versions that support current CPU and motherboard power delivery requirements. The Segotep is listed as ATX compliant but does not specify a version number in the provided data. You should prefer the Thermaltake if you need explicit support for the latest EPS connectors. The lack of a specific version for the Segotep makes direct comparison difficult.
pcie connectors
Graphics card power depends on available connectors. The Segotep includes four PCI-E 6+2 Pin connectors, supporting modern high-draw GPUs like the 40-series. The Thermaltake’s connector count is not listed in the provided data. You cannot verify if the Thermaltake offers the same number of PCIe cables. If you need multiple high-power GPU connections, the Segotep’s known count is advantageous. For the Thermaltake, you would need to check the manual for exact connector availability.
Which PSU fits your build needs
High-end gamers with top GPUs
The Thermaltake delivers 850W continuous power, providing the headroom needed for demanding graphics cards. Its fully modular design allows for cleaner cable management. The 80 PLUS Gold rating ensures efficient energy use under heavy loads, protecting your expensive components during intense gaming sessions.
Budget builders with mid-range parts
The Segotep offers 650W of power, which is sufficient for standard mid-range systems. Its non-modular design reduces cost while still providing necessary connectors. The 80 PLUS Gold certification guarantees good efficiency, helping you save on electricity bills without sacrificing reliability for everyday computing tasks.
Users needing global voltage support
The Thermaltake complies with Intel ATX 12V 2.3 standards, ensuring broad compatibility. While the Segotep mentions global voltage adaptation, the Thermaltake’s robust construction with Japanese capacitors offers stability. Its fully modular nature allows you to use only the cables you need, reducing clutter in any case.
