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.

500W, modular, not too expensive - an ideal partner to a cost efficient system? We put OCZ's revamped ModXStream Pro to the reviewers block to see if it'll hold up to our barrage of tests in order to evaluate noise, efficiency and power quality.

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?

In-Win sent us its camo styled, CWT built modular PSU and it certainly does quite a bit to differentiate itself in the market. We tested all 750 watts of the Commander to see if In-Win is worthy of your consideration in the PSU realm.

If you like a bit of bling in your case and don't care for extreme wattages, Hipers Type R II with its shiny blue casing, LEDs and metallic fan could be right up your street. We test this feature filled mainstream performer to see if it's cheap for a reason, or just fantastic value for money.

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?

Rated Silver in the 80Plus program, this super efficient, premium wattage power supply is Cooler Masters leading model. Ruggedised and full of connectors, is it everything the "ultimate" claims to be?

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.

From its Tagan roots we have an inexpensive, yet powerful 850W power supply from Silver Power. We find out if it's a wolf in sheep's clothing or bit of bling strapped to a brick.
