This is a minor technical detail, but it reflects the GX2 being the more recent design in the lineup.
protections
The GX2 explicitly lists industry-grade protections including Over Power (OPP), Over Voltage (OVP), Under Voltage (UVP), and Short Circuit (SCP) protections. The Smart product data does not specify these protection features in the provided text. While both likely include basic safeguards, the GX2’s detailed listing gives you confidence in its ability to protect expensive components from electrical faults. You should prioritize units with clearly stated protection circuits for system safety.
dimensions
The Smart 700W measures 5.91 inches in length, 3.5 inches in height, and 5.8 inches in width. The GX2 measures 9.3 inches in length, 4.6 inches in height, and 7.7 inches in width. The Smart unit is significantly more compact. If you have a smaller case or limited space, the Smart model fits more easily. The GX2 is a larger, standard-sized unit. You must check your case’s maximum PSU length compatibility before choosing the GX2.
Which Thermaltake PSU Fits Your Build
Users needing higher total power output
You should choose the Smart 700W if your system requires more continuous power. It offers 700W compared to the GX2’s 600W. Both use 120mm fans for airflow. The Smart model supports ATX 12V V2.3. This extra wattage helps if you plan to upgrade components later or run power-hungry hardware under load.
Users prioritizing energy efficiency and stability
The Toughpower GX2 600W Gold is better for efficiency. It reaches up to 90% efficiency under the 80 Plus Gold standard. This reduces wasted heat. It also features low ripple noise for stable voltage. The single 12V rail design supports modern GPU demands well. This ensures reliable operation for critical components like your graphics card.
Users wanting modern ATX specifications
If you need the latest standards, pick the GX2. It supports ATX 12V V2.4 and EPS V2.92. The Smart model only supports ATX 12V V2.3.
