As usual we grabbed our dBA meter, enabled the PSU by hot-wiring it and started to listen to see if it made any significant noise. Short and simple, it's really silent.
The human hearing system has different sensitivities at different frequencies. This means that the perception of noise is not at all equal at every frequency. Noise with significant measured levels (in dB) at high or low frequencies will not be as annoying as it would be when its energy is concentrated in the middle frequencies. In other words, the measured noise levels in dB will not reflect the actual human perception of the loudness of the noise. That's why we measure the dBA level. A specific circuit is added to the sound level meter to correct its reading in regard to this concept. This reading is the noise level in dBA. The letter A is added to indicate the correction that was made in the measurement.
As always we measure 75 CM away from the product (usually the distance between you and a desktop computer), and yes... this test is always a tad subjective yet we measured 33~34 dBA and that's including surrounding noise levels, that's just perfect. Under full PC stress we can hardly measure the dBA level as all other components (fans/VGA/CPU/Chipset cooler) that make noise subjectively influence the results. The PSU is more silent than them.
But sure, in a normal PC, you will not be able to hear this PSU. All in all, very silent and thus highly recommended to any of the audiophiles that like silence (yours truly included). The RPM delta is pretty much very similar to the revolution series.
Enermax Liqtech 120X and 240 review We test and review the all new Enermax Liqtech 120X and 240 Liquid coolers. Can it keep up with similar Asetek and compeeting products? Let's find out!...
Enermax Fulmo GT review We review and test the Fulmo GT. Enermax has been going very strong with their power supply and fans. For a while now they also offer PC cases, and more recently they released what seems to be the biggest chassis I've ever laid my hands on. This chassis series has HPTX support for the bigger than biggest motherboards and some pretty cool features as well.
Enermax KW001 Briskie Keyboard mouse combo review Keyboard kits come in all sizes, shapes and forms .. and that's next to a gazillion of manufacturers that offers them. Surprisingly enough a few weeks ago Enermax, the guys behind the best power supplies and the brightest fans also launched a keyboard/mouse combo. Briskie is all about value and as such for 25 USD/EUR you get a mouse and what we think is a very decent wireless RF keyboard.
Enermax Platimax 850W power supply review Enermax always is able surprise us, they now have released the Platimax power supplies, that means a platinum certification and yeah .. that boils down to a 94% efficient product. Very few products get this certification. Today we'll grab a couple of older older supplies and see if what they claim is true, can we really save on energy. We fire off three PSU's at a P55 / Core i7 870 based system setup with a GeForce GTX 590. We then monitor power consumption in idle, CPU productivity (stress) mode and then lock into a gaming session.
