To provide our readers with the most accurate results, Overclock3D uses a custom built PSU load tester on all reviews. This not only gives much more reliable results than the testing methods employed by other sites, but also allows for all current and future review results to be compared side-by-side.
Efficiency tests are performed by measuring the wattage consumed by the power supply at the mains (Mains Draw) against the power consumed by the OC3D power supply stress tester (PSU Load). These results may not be 100% accurate, but have proven to be extremely close to results obtained from professional equipment.
In our continuing efforts to make power supply reviews more thorough, rather than simply checking voltage stability, Overclock3D will now be recording the temerature of each PSU as it undergoes testing. Temperature recordings will be taken from the underside of the PSU's outer casing at 0%, 50% and 100% load levels using a laser infrared thermometer in an attempt to gauge how much heat is likely to radiate into the end-users case.
Noise Level Measurements
Possibly the hardest part of any PSU review is summarising the level of noise given out by the unit. The threshold for what is considered 'noisy' varies from person to person and therefore what I may consider a quiet unit, another person may consider extremely loud. For this reason, all reviews from this point forward will be using a dBA meter to measure the level of noise output by the PSU.
All noise measurements are taken in a quiet room with the dBA meter located 30cm away from the exhaust fan on the unit at 0%, 50% and 100% load levels. The results shown below have had the ambient noise levels deducted from the results to give a better representation of how likely you are to hear the PSU in a normal environment.
Being the first PSU on OC3D we've tested using this method, it's hard to comment on the performance compared to some of the previous 1kw units we've reviewed. However, I will say that from a personal standpoint I found the M1000 to be very quiet at low to medium loads, and perfectly acceptable for my tolerances at full load.
