We put eight 720-750W PSUs through their paces to separate the champs from the chumps.

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.
