Return rates of power supplies

After the motherboards on Tuesday, here are the returns rates for power supplies. We use the same methodology used 6 months ago, the figures coming from a large French online store. These figures take into account cards sold between September 2008 and February 2009, namely after between 6 months and a year of use. The statistics by make are based on a minimum sample of 500 sales, those by model on a minimum sample of 100 sales.

- Antec 0.84% (against 1.6%)
- Seasonic 1.31% (against 1.9%)
- CoolerMaster 1.52% (against 2.0%)
- Corsair 1.67% (against 1.8%)
- Fortron 1.7% (against 1.4%)
- Enermax 3.1% (against 1.5%)
- Thermaltake 3.45% (against 2.8%)
- Hiper 4.47% (against 4.6%)

In comparison with the last set of stats, Antec, Seasonic, Coolermaster and to a lesser extent Corsair now have lower returns rates. On the other hand Fortron, Enermax and Thermaltake.

If you look at the figures more closely, only 6 power supplies sold at over 100 in number have a returns rate of equal to or over 3%. The least reliable is the Hiper HPU-4S425-PU with no fewer than 7.6% breakdowns. Next come the Enermax Modu82+ 625W at 4.7%, the Hiper HP-4M530 at 4.5% and the Corsair 1000HW at 4.2%. Then we have the Seasonic M12-700 at 3.7% and the CoolerMaster RealPower 850W at 3.4%.

For 500 to 550W supplies, we get the following list:

- CoolerMaster RealPower 520W 0.5%
- Seasonic M12II-500 0.7%
- Antec TruePower Trio 550W 0.8%
