be quiet! PURE POWER 12 M 1000W 80+ Gold PSU Review

Power Efficiency Testing

be quiet’s PURE POWER 12 M 1000W is an 80+ Gold Rated power supply, on throughout our testing our review unit was able to deliver 90+% efficiency levels at all tested loading levels, which is an impressive result. Not all 80+ Gold rated PSUs are 90%+ efficient in all of our tests, and that means that the PURE POWER 12M 1000W sits within the higher-end of the 80+ Gold Efficiency spectrum, placing it close to some 80+ Platinum rated units.  

Voltage Ripple Testing

Voltage Ripple is a problem that has largely been solved by most modern PSU markers, with modern units being able to deliver remarkable levels of voltage stability under load. The fact that these variations are measured in millivolts (mV) says a lot, an even the worst PSU on our graphs, Corsair’s original 2014 RM1000 does not have voltage ripple levels that are in any way concerning.

With this in mind, be quiet’s PURE POWER 12 M 1000W power supply delivers strong voltage ripple results. Yes, there are units in the charts below that have less voltage ripple, but the PURE POWER 12 M still delivers great results. 

Conclusion – A solid ATX 3.0 power supply
