Efficiency is a key factor in modern systems. Organizations such as Climate Saver Computing™ are focused on improving the efficiency of a computer’s power delivery. Today’s average desktop PC wastes over half of the power delivered to it, and the wasted electricity unnecessarily increases the cost to power computers as well as the emissions of greenhouse gases. Enermax is committed to reduce this waste and to combat climate change by meeting and exceeding Climate Saver Computing guidelines, setting new benchmarks for the PC PSU industry by reaching 82-88% efficiency with all of the new MODU82+ and PRO82+ series at 20%, 50%, or 100% load. These new power supplies are also some of the quietest units in the world thanks to two new patented technologies: SpeedGuard and AirGuard. SpeedGuard allows the PSU fan to operate only at 400 to 500 rpm when the power supplies are under 50% load. It lowers the total noise profile by an astonishing 5 dBA. AirGuard is a mechanical design which bends the housing around the air-inlet to the fan and it help to reduce the total noise level by up to 2 dBA. Besides being one of the first that complies with Intel’s ATX12V v2.3 standards, MODU82+ and PRO82+ offers some of the strongest +12V rails in its class. Both series are rated at 40°C with triple +12 rails that can support up to an amazing 25A on each rail. In addition, The MODU82+ series come with 12 pin modular connectors that present endless combinations and possibilities for future CPU and graphic needs.
"Wow! What a power supply! We could not only deliver its labeled 525 W power at 50º C but also maintained efficiency between 85% and 90% all the time! In fact this is the power supply with the highest efficiency we reviewed so far. Not only that. We could pull almost 600 W from this unit still with 85% efficiency. That is impressive." "Another highlight from this product is its noise level. This was the quieter power supply we reviewed to date." "...it is worth every penny,"
“The Enermax Pro82+ and Modu82+ both perform extremely well in our tests, and as such we are awarding both series our Gold Editors' Choice Award. Users can't go wrong with these power supplies, and silence (without going fanless) has been redefined today. Enermax truly has the quietest air-cooled power supplies in the market right now, and the prices (at least for the smaller versions at the moment) make these units relatively affordable and very attractive.”
"Voltage regulation was also top notch as was ripple suppression but where this power supply really shines is in the noise output department. Not once did the noise produced by the Pro82+ rise above a faint whisper so we can definitely see this unit or its modular brother being a favorite with both quiet PC aficionados and HTPC enthusiasts." "The Pro82+ has proven that you don’t have to spend megabucks to get a stable, quiet and efficient power supply and because of this it gets our Dam Good Value Award."
The Enermax Pro 82+ 425W is a smart little power supply. For anyone with a mid-range system, this unit would accompany it nicely. Its quality, aesthetics and stability are all factors which can’t be knocked – not to mention noise. Our wallets are usually the decider though when choosing a PSU. Fortunately at such tidy price, the Enermax Pro 82+ 425W is a very tempting offering. Apart from it not being modular (there is a modular version though); there’s nothing wrong with it. Bottom line, this is one of the best bang for buck units we've ever tested and more than deserves the "Value Award" it's now received. Good job Enermax.
