ASRock’s Z490 Phantom Gaming 4SR is the first retail mainboard to require a power supply according to Intel’s ATX12VO specification. The power supply only supplies the board with 12 volt current, which the voltage converters on the mainboard convert to 5 and 3.3 volts for all connected devices. The built-in CPU socket LGA1200 is intended for Intel’s Comet Lake-S processor series, led by the Core i9-10900K.
The Z490 Phantom Gaming 4SR therefore lacks the typical ATX connector with 24 pins. In its place is a ten-pin socket as the main power supply. A six-pin PCI Express connector provides additional power, and the processor has the typical EPS connector with eight pins. In the top right are two new 4-pin sockets that supply up to four SATA 6G drives such as SSDs or HDDs with energy. Data carriers can no longer be connected directly to ATX12VO power supplies.

Manageable equipment
Despite the high-end Z490 chipset, the equipment of the Z490 Phantom Gaming 4SR corresponds to the entry-level class: only a single M.2 slot offers space for a fast PCI-Express SSD, the WLAN card can handle a maximum of Wi-Fi 5 (802.11 ac) and the LAN controller (Intel I219V) transmits a maximum of 1 gigabit per second.

The I / O panel on the back offers six USB ports, including 2 × USB 3.2 Gen 2 (10 Gbps, type A + C), USB 3.2 Gen 1 (5 Gbps, type A) and USB 2.0 (type A) ), as well as PS / 2, HDMI 1.4 and three audio jacks (on Realtek ALC1200 sound chip).
Power supplies according to ATX12VO specifications have not yet made it to the market. Manufacturers like FSP have so far only shown pre-series models.
