Antec TrueBlue 2.0 480W Power Supply

Test Results:

Loads are reported at 4 different levels (Low, Typical, Heavy, and Max), the numbers will vary slightly between power supplies because voltage levels have a direct effect on current going though the resistors. Ambient temperature (outside the case) would vary between 23.8-26.7°C (75-80°F), which was somewhat proportional to the load level being tested, however the main concern was keeping the internal temp below 50°C. All PC power supplies are "switching power supplies", so please keep in mind that voltage levels will always vary between PCs because loads are always different (and quite dynamic).

• Things to consider:
  1. Voltage Regulation (% above/below nominal)
  2. Efficiency (particularly under a "typical" & "heavy" loads)
  3. Safety (Does it shutdown under unsafe conditions?)
  4. Maximum Real Power Output (does it meet rated output?)
  • Two potential reason a power supply did not meet its rated maximum power output:
    1. Voltage exceeded maximum tolerances
    2. PSU shutdown (overheat or overload condition)

Note: Maximum tested load (red background) may not always be the maximum PSU output rating (mentioned as reason #4 above). We try to get as close as possible to the maximum rated output, but the design of the load testing device only works in incremental numbers.

Comments:

• Extremely good voltage regulation, generally 1% or better!
• Good efficiency, ~80% under typical / heavy load.
• Properly shutdown from overload conditions
• Tested to ~530W peak (shutdown within a minute or two at this load)
• 120mm fan was really quiet, even under heavy load
