Cooler Master Elite Power 400 W Power Supply Review

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.
