• 0,2% : Cooler Master Elite Power 400

@""

Conclusions

Although with performance not comparable to more expensive models, Elite Power 400 W can really deliver its labeled wattage (in fact we could pull up to 420 W from it), provides an outstanding voltage regulation, it is very inexpensive and won’t damage your computer.

When we pulled between 40% and 60% from its labeled wattage (between 160 W and 240 W) efficiency touched 80%, which is certainly a good news, since most low-end units provide efficiency below 80% all the times.

But since it didn’t show efficiency above 80% all the times and noise and ripple levels were very high (touching the 120 mV limit on +12 V output when we pulled 400 W from it), we can’t recommend it.

• 0,3% : Cooler Master Extreme Power 400

@""

Conclusions

Cooler Master eXtreme Power Plus 400 W is capable to deliver its labeled power at high temperatures. But as we always like to point out, maximum power isn’t everything. This unit presents lousy efficiency and noise and ripple levels above the maximum allowed, which can lead you computer to present random behavior (“freezing,” random resets, Blue Screen of Death, etc) and overload components. Therefore we can’t recommend this product.

The three units from eXtreme Power Plus series that we’ve reviewed so far (400 W, 460 W and 500 W) are based on the same design, and the differences are that the 460 W and the 500 W models use more powerful rectifiers on the +5 V and +3.3 V outputs (the +12 V outputs from these three models use the same rectifiers). The 400 W and the 460 W models use the same switching transistors, while the 500 W model uses more powerful ones.
