Hiper Type-R 580W Modular Power Supply

Load 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). Also, 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 (so it can be a little above or below).

AC Ripple Test Results:

Using a Tektronix 2215 Oscilloscope, we check for AC ripple that is present in the DC power. We only checked the +3.3V,5V,+12V1, and +12V2 rails (not the -12V or 5Vsb). Potential frequencies could be in the 60Hz range (which is what the AC line power is in the US), or in the higher KHz range closer to the PSU's switching frequency. The guideline tolerance is 50mV p-p on the +3.3V & 5V rails, and 120mV p-p on the +12V1 & +12V2 rails.

An interesting thing to note, in the Hiper Type-R manual, they specify different ripple tolerances than what is listed in the ATX guidelines. Hiper lists 70mV on the +3.3V p-p, 100mV p-p on the +5V, and 120mV p-p on the +12V1 & +12V2 rails. Thankfully the actual ripple was much lower than either printed specifications.

I've had someone ask me before what the scope actually looks like, so below is a sample picture I took. The scale is set to 20mV/div (I don't remember the time division). Ripple is measured from Peak-to-Peak, so in the picture the "spikes" go one division up and one division down, and at 20mV per division that would mean 40mV p-p. Care must be taken when measuring ripple, an improper setup can lead to erroneous results.

Comments:

• The -12V rail was generally always high and typically around 10% tolerance (nearly exceeding maximum allowed).
• All voltages stayed within acceptable tolerances.
• Good Efficiency, ~78-80% under typical loads.
• 12V Rails loaded each to ~18A, voltages still stayed within 2% of tolerance.
• Verified peak load rating of 630W.
• Both fans were very quiet, even under heavy load.
