With a trade-name like “be quiet!”, you’d expect products to be noiseless. – Which is pretty much the case with the Dark Power Pro 650W power supply unit.

Its 120mm fan makes almost no sound at all, cooling the internal components as they transfer up to 650 watts of power to the box, along modular cables. The fan remains spinning even after the PC is shut down to clear any residual heat left in components.

Four 12-volt rails, rated at up to 20 amps each, or a combined maximum of 52 amps jointly, make up to 624 watts of power available on these lines. The unit is ideal for SLI and Crossfire, with 2 PCIe cables ready to power your graphics.

It comes with a standard 20/24 pin P1 plug for the motherboard, a 4-pin and an 8-pin plug for the CPU’s supply, – No matter how modern your motherboard, this PSU’s ready to plug-in and power-up – 8 Molex plugs as well as 8 SATA power connectors too.

Its output is very stable and well within the standard ATX specifications. Overall it’s a very efficient mid-end unit. PC builders who are looking for a great PSU deal to power a powerful PC take note.

Bearing all the above in mind, you might expect to be looking at a price which matches the other standards; that is to say, high: You’d be mightily surprised to learn that this silent-but-deadly powerhouse actually can be bought for less than £102.00UKP Inc VAT at time of writing! (Around $160USD.)

What do you think? ‘Good value? – Or do you know of something better? If so then please do tell.
