EVGA’s SR-3 Dark is a motherboard tailored to intel xeon W-3175X, and its prototype has been publicly displayed on Computex 2019. After months of waiting, the company finally accepted the reservation, retailing for $1,800, $200 less than the previous price tag of $2,000.
It is reported that the board in the market, the standard Asus ROG Dominus Extreme and Giga’s C621 Aorus Xtreme motherboard, is currently the only three on the market to support the Intel 28 core 56 thread monster processor board. The EVGA Dark SR-3 is the flagship, and in addition to the luxurious power supply, solid materials and rich PCIe expansion, there is an all-in-one RGB magic water-cooled head press, which is rare in the past.
Like EVGA’s Z390 DARK motherboard, the SR-3 motherboard is surrounded by six SMT DIMM slots for high-frequency and low-latency RAM overclocking. On other main boards with LGA 3647, you can find 12 DIMM slots next to the socket.
The SR-3 DARK has an Intersil NOVA-1 PWM controller, known as the ES PWM IC. The motherboard uses the 18 plus 1 (CPU and VCCO) Intersil 99380 power stage (80A) and should provide at least 1200 watts of power for the CPU slot. Although this is a much smaller VRM design than the ASUS ROG DOMINUS Extreme with a 32-phase design, EVGA is said to want to maximize the performance of the unit area at this specific size, which is much smaller than MINUS DO Extreme or C621. AORUS XTREME features a larger EEB form factor.
Powered by a total of four 8-pin EPS connectors and a 24-pin ATX connector. You can find the frequently used DEBUG LEDs and power/reset buttons in the upper right corner of the board. On the I/O side, the motherboard has six PCIe 3.0 x16 slots and dual M.2 slots. The PCIe slot is connected to a separate 6-pin EPS connector and provides more power if multiple devices are running at the same time. The motherboard also has a C622 PCH, a slight upgrade to the C621 PCH used by Asus and Tsuka on their respective HEDT boards. You can also enable/disable each individual PCIe slot via the switch next to the SATA port to save channel usage.
The C622 chipset should theoretically provide higher bandwidth for the PCIe slot because it has an x8 uplink compared to the x1 uplink on the C621 chipset. Storage options on the motherboard include six SATA III ports and dual U.2 ports. The board has three Ethernet ports, two of which are 10Gb and nine USB 3.0 connections, and a USB 3.2 Gen 2 (Type-C/ Type-A) port.
