Not much has changed in power supply requirements since then, other than the obvious, an ever-increasing demand for more wattage! Today it is quite common for a high-end video card to draw more than 200 watts at load and in multi-GPU configurations, or when using multiple, multi-GPU cards, the power needs can quickly overwhelm lesser supplies. Even those 1Kw units, which back then might have been considered the mother of all PSUs, can begin to look a bit skimpish when you start talking tri- or quad- SLI or Crossfire scenarios.
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. Ultra sent over two units for review today, the 600W and the 1050W.
