With systems with multiple video cards requiring more power everyday, 1,000 W power supplies are becoming very common. OCZ has released a new 1,000 W product in the market, ProXStream 1000 W, targeted to power-hungry consumers that are willing to put three or four high-end video cards (this unit has four six-pin VGA power connectors) and several hard disk drives inside their systems. What is really different about this power supply compared to other 1,000-watt units around is it uses a small form factor, being at the same size of any standard ATX power supply, due to its interesting internal design using two printed circuit boards stacked. We completely disassembled this new unit from OCZ to see how it looks like inside and what design and components were used.
