Ultra X4 600w and 1050w Power Supplies Review
 

It was two years ago when we reviewed Ultra's then-new line of X3 power supplies, the 600, 800 and 1000 watt models. Not much has changed in power supply requirements since then, other than the obvious, an ever-increasing demand for more wattage! To accommodate the need for greater amounts of power, meet revamped cabling requirements and target the latest specifications for efficiency, Ultra has updated their X-series of power supplies and is releasing a new lineup of fourth generation models beginning with 400, 500, 600, 750, 850, 1050 and 1200 capacities. Dubbed the - you guessed it - X4, these latest power supply offerings from Ultra bear a striking similarity to their previous X3 generation PSUs.
