True Wattage Guarantee
The wattage you see isn’t always the wattage you get.
Some brands tweak tests to achieve great wattage
ratings, but in reality, they deliver much lower maximum
wattages. Don’t be fooled by wattage tricks.
Continuous Power
Other PSUs claim a certain wattage by using unrealistic
testing environments like 25°C, but in realistic
conditions, they often fail to reach this wattage. XFX
PSUs guarantee the advertised wattage, even at well
above standard operating conditions such as 50°C.
Efficient Power Use
80 Plus Bronze certified means that this XFX PSU
has an 85% power efficiency (only 15% of the power
drawn from the outlet is lost). Compare that to
non-certified PSUs, which lose at least 20% of power
drawn. With the XFX PSU, get every watt you pay for.
Clean Power
Power drawn from your AC outlet is typically dirty
with voltage spikes and fluctuations, which can
harm vital PC components. XFX PSUs are designed to
deliver tight DC voltage regulation with minimal AC
ripple, giving you safer, cleaner power. This can also
reduce audio distortion and screen flicker especially
for high power gaming systems
Industrial Design: It’s what’s on the inside that
counts but we got both bases covered.
Easy Rail: With a Single Rail +12V, it gives
ample 12V output with OCP for reliability.
Tight Voltage Regulation (±5%): Improved load
regulation to reduce voltage variations gives
the user a more stable machine.
