Testing results

Our Chroma load-testing procedures can be found at this link.


Load 10% 25% 50% 75% 100%
Efficiency 83.1% 90.9% 93.0% 90.4% 88.5%

Very few supplies manage over 90 per cent efficiency across a wide load. Considered across the range most would use - 25 per cent to 75 per cent - SilverStone does manage that magic 90 per cent figure.


In terms of regulation, we're looking at just how well the supply is able to hold to the various lines. The ATX spec. has a +/- 5 per cent leeway on all but the -12V line.

Line/Load 3.3V 5V 12V
10 per cent +0.4% +1.1% +1.4%
50 per cent -0.5% +0.8 +0.8%
100 per cent -1.6% -0.5% +0.2%

SilverStone claims tight regulation in the Strider Essential Gold's accompanying literature. We see that borne out as the maximum fluctuation is less than two per cent.

Regulation - cross-load

How about providing uneven loads that stress particular voltage rails? In the first attempt, we've put 35A on the 12V rails, and 1A on the 3.3V and 5V rails. This can actually be somewhat typical for a system heavy on graphics and CPU power. In the second, we've turned the tables and gone for 12A on both the 3.3V and 5V rails - highly unlikely in a real-world environment - and just 2A on the 12V - even more unlikely.

Line/Load 3.3V 5V 12V
Cross-load 12V focus +1.2% +1.0% -1.0%
Cross-load 3.3V/5V focus -2.0% -1.1% +2.0%

Hammering one part of the PSU power delivery while using just a small portion of the other can throw cheaper supplies out of kilter. Regulation isn't quite as tight, naturally, but on a par with other 80 PLUS Gold supplies we've seen recently.


Line/Load (mv - p-p max) 3.3V 5V 12V
10 per cent 10mV 10mV 20mV
50 per cent 15mV 20mV 30mV
100 per cent 30mV 30mV 40mV

The ATX v2.2 spec states that the maximum permissible ripple is 120mV for the 12V line and 50mV for others.

PSUs convert AC power into DC, but doing so requires the AC waveform to be suppressed. What we're really testing here is the quality of the supply's rectifier and any smoothing capacitors in getting rid of this unwanted up-and-down ripple. Performance is well within ATX specifications but not as sharp as found on the similar EVGA SuperNOVA.


Temperatures Intake Exhaust
10 per cent 28°C 36°C
50 per cent 33°C 41°C
100 per cent 38°C 47°C

Fan performance

Temps are good but they mean little in isolation. Obtaining accurate noise readings is near-on impossible when the supply is connected to the Chroma test harness and dual-unit load-tester. We can test the manufacturer's quietness claims in a different way, by using an AMPROBE TMA10A anemometer placed directly over the centre of the PSU. The anemometer records the airflow being pushed/pulled from the PSU's fan. We can use a Voltcraft DT-10L RPM meter to measure the rotational speed of the fan, too.

Load Fan RPM Airflow Noise
10 per cent 700rpm circa-20cfm Very quiet
50 per cent 1,100rpm circa-35cfm Quiet
100 per cent 2,000rpm circa-70cfm Noticeable

You won't hear the fan under normal conditions. The story changes if you manage to use more than 400W as the noise escalates rather quickly.
