Just under a year since the specification was first announced, the ATX 3.0 era for power supplies is now underway. The updated version of the Intel-maintained specification introduced several notable changes to PC power supply designs, most notably the introduction of the 600 Watt-capable 12VHPWR connector and associated cabling. Altogether, ATX 3.0 is designed to lay the groundwork for future video cards (and other high-powered accelerators) by providing for a single-cable power connection that can better accommodate the high total and rapid shifts in power consumption a video card can undergo. The biggest change since the addition of the 12V 6-pin “PCIe” power connector in the late 00s, the ATX 3.0 era has come with some new opportunities, both for computing products and for computing...
