Thermaltake's mission to put RGB everywhere continues with this pricey but effective PSU.

Even PSUs can be RGB these days, but this high-end Aerocool model has a few other tricks up its sleeve.

We constantly recommend the 650W Be Quiet! Dark Power Pro, but does the 850W afford the same awesome efficiency and virtual silence? With the same style of modular cables, shiny box, and a very similar build it be just as good or it might suffer from being just too hot.

We've rounded up and finalised our opinions of the Seasonic M12D, and now it's time for the overall performance results. Does Seasonic's champion 80Plus Silver model hit the spot to overrule the Antec Signature, Enermax Revolution 85+ and Cooler Master UCP 900W?

Antec's Signature is its definitive power supply, built on a idea of quality it's not cheap but it sports an 80 Plus Bronze efficiency, a semi-modular design and "hand certification." Are these the ingredients required to earn the bit-tech stamp of approval?

Lian Li is famed for its high quality cases but not yet for its PSUs - is that about to change? Will the company instil the same level of design and build quality into powering a PC like it does housing one? We jacked up the voltage to find out.
