Dimension comparison
Design and build quality
The physical construction of a power supply unit significantly impacts its longevity and integration within a PC case. The Thermaltake Toughpower GX2 80+ Gold 600W features a black powder-coated casing designed to seamlessly fit various PC styles. It utilizes black sleeved cables which contribute to a cleaner internal aesthetic without requiring additional aftermarket sleeves. The compact casing measures 125mm in length, ensuring an easy fit in almost all modern PC cases where space behind the shroud might be limited. In contrast, the CORSAIR CX550 80 Plus Bronze Non focuses on internal component quality, highlighting the use of high quality capacitors that provide superb performance and reliability. While external aesthetics are noted for the Thermaltake Toughpower GX2 80+ Gold 600W, the CORSAIR CX550 80 Plus Bronze Non emphasizes internal durability through its component selection.
Efficiency and Certification
Power efficiency determines how much electricity is drawn from the wall versus how much is delivered to the components. The Thermaltake Toughpower GX2 80+ Gold 600W is listed with 80 PLUS Bronze Certified status, providing up to 88% operational efficiency. This level of efficiency helps in generating less heat and lowering energy costs compared to non-certified units. However, the CORSAIR CX550 80 Plus Bronze Non supports 80 Plus Gold efficiency up to 90% and is optimized for C6 or C7 States ready. This higher efficiency rating means the CORSAIR CX550 80 Plus Bronze Non wastes less energy as heat during operation, potentially leading to lower electricity bills over the lifespan of the unit and reduced thermal load on the system.
Cooling and Noise
Thermal management is critical for maintaining stable power delivery and ensuring a quiet computing environment. The Thermaltake Toughpower GX2 80+ Gold 600W employs a 120mm thermally controlled low-noise cooling fan. This fan only spins at high speed when the power supply is under heavy stress, slowing down for quieter operation at lower loads. Similarly, the CORSAIR CX550 80 Plus Bronze Non utilizes an Ultra Quiet 120mm Fan with Dynamic Bearing technology for superior cooling performance and silent operation. Both units rely on 120mm fans, suggesting comparable airflow potential, but the dynamic bearing in the CORSAIR CX550 80 Plus Bronze Non may offer enhanced longevity and consistent noise levels over time.
Connectors and Modularity
Connectivity options dictate which components can be powered directly without adapters. The Thermaltake Toughpower GX2 80+ Gold 600W features black sleeving and casing but does not explicitly list connector counts in the provided data, though it guarantees full continuous power. The CORSAIR CX550 80 Plus Bronze Non specifies Non Modular Connectors with a detailed breakdown: Main Power (24 pin) x 1, ATX 12V (4plus4 pin) x 1, SATA (5 pin) x 6, PCI-E (6plus2 pin) x 2, peripheral (4 pin) x 3, and FDD x 1. This detailed enumeration for the CORSAIR CX550 80 Plus Bronze Non provides clarity on its ability to support multiple drives and GPUs, whereas the Thermaltake Toughpower GX2 80+ Gold 600W relies on general compatibility statements.
Power Stability and Protections
Stable voltage delivery is essential for protecting sensitive components like CPUs and GPUs from damage. The CORSAIR CX550 80 Plus Bronze Non features a Single plus12V Rail Design which supports today's GPU demands, supporting DC to DC design for stable reliable power. It also ensures low ripple noise to keep performance-critical components such as VGA cards to operate reliably for longer. Furthermore, it includes Industry Grade Protections including OPP (Over Power), OVP (Over Voltage), UVP (Under Voltage), and SCP (short circuit) protections. The Thermaltake Toughpower GX2 80+ Gold 600W guarantees full continuous power but lacks specific details on rail design or ripple noise in the provided data, giving the CORSAIR CX550 80 Plus Bronze Non an advantage in documented stability features.
Compatibility and Size
Form factor compatibility ensures the power supply fits within the chosen chassis. The Thermaltake Toughpower GX2 80+ Gold 600W boasts a compact casing with a 125mm length, which ensures an easy fit in almost all modern PC cases. This is particularly beneficial for small form factor builds or cases with restrictive PSU shrouds. The CORSAIR CX550 80 Plus Bronze Non does not specify its length in the provided data, though standard ATX PSUs are typically around 140mm to 160mm. For builders prioritizing maximum space savings inside the chassis, the Thermaltake Toughpower GX2 80+ Gold 600W offers a verified compact dimension that may facilitate easier cable management in tighter enclosures.
Price and Value
Cost is often a deciding factor when performance differences are marginal. The Thermaltake Toughpower GX2 80+ Gold 600W is priced at $65.99. The CORSAIR CX550 80 Plus Bronze Non is priced at $59.99. Considering the CORSAIR CX550 80 Plus Bronze Non offers a higher efficiency rating of Gold versus Bronze and includes a comprehensive list of protection features, it presents a stronger value proposition at a lower price point. The Thermaltake Toughpower GX2 80+ Gold 600W commands a higher price despite the lower efficiency certification, though it does offer a higher wattage capacity of 600W compared to the 550W implied by the competitor's model name.
Which one should you buy?
Choosing between these units depends on specific system requirements and budget constraints. If maximum power capacity and compact size are the primary concerns, the Thermaltake Toughpower GX2 80+ Gold 600W is the suitable choice due to its 600W rating and 125mm length. However, for most users seeking efficiency and component safety, the CORSAIR CX550 80 Plus Bronze Non is the recommended option. It provides 80 Plus Gold efficiency, extensive industry-grade protections, and a lower cost. The detailed connector list and stability features of the CORSAIR CX550 80 Plus Bronze Non make it a robust foundation for a reliable gaming or work PC, edging out the Thermaltake Toughpower GX2 80+ Gold 600W in overall value and electrical performance.
