ASRock Z490 Phantom Gaming 4SR Features First ATX12VO Power in Consumer DIY Board


PC power delivery is up for a change and I can’t seem to find the article where we discuss the misses of the current  24-pin connector for motherboard power but a new standard is being presented. That’s ATX 12VO, and has found OEM adoption steadily with no consumer market ready for it yet as well as motherboards. That changes with ASRock announcing the ASRock Z490 Phantom Gaming 4SR. With no 24-pin connector, this board uses ATX12VO with a smaller 5-pin 12V connector. Another 6-pin PCIe connector adds another 12V as well as the 8-pin EPS connector serving 12V.  A pair of 4-pin connector presumably serves the 5v and 3.3v output ports for use with SATA power, etc.

Some changes to the board layout includes power phases for converting the 12V to the lower voltages for other components. Other than that the motherboard is practically the same as traditional motherboards although finding a ATX12VO power supply is a challenge depending on your region. the board is still a mainstream Z490 launch model and will feature WIFI via M.2 device.
