Enermax Pro 82

Power supply units


When Enermax contacted us regarding reviewing a power supply for them, we were pleasantly surprised. With such a prime range of PSUs, it’s difficult to see why Enermax would release yet another series of units. However this was made clearer after doing some research…price. All of Enermax’s units top the £60 bracket, but the Pro 82+ series is aimed more so at the low-mid range and the price reflects this. But by still maintaining price, Enermax boasts that the Pro 82 range provides outstanding efficiency and a quiet fan. Let’s see how this 425w unit holds up
