TS Series 550W PSU

True Wattage Guarantee

The Wattage you see isn't always the Wattage you get. Some brands tweak tests to get great Wattage ratings for their power supplies. The Wattage ratings may be based on unrealistic testing environment like 77°F (25°C). But in real world situations, their power supplies deliver much lower maximum Wattage. XFX PSUs guarantee the advertised Wattage, even above standard operating conditions at 122°F (50°C).

We guarantee the Wattage advertised is the the minimum Wattage you get.

TS Series 550W PSU

Extreme Heat Tested Capacitors

The internal PC operating temperature is around 95°F (35°C). But the internal PSU temperature can be much higher. XFX uses all high-quality capacitors rated to withstand temperature of up to 221°F (105°C).

XFX PSU's use high quality extreme heat tested capacitors designed to withstand up to 221°F (105°C) operating conditions, far above normal operating standards.
