In Win Power and Cooling Products at 2025 CES: 2500W PSU with Four 12V2x6

Fancy a rendering farm with four NVIDIA GeForce RTX 5090 graphics cards sitting on top of an AMD Ryzen Threadripper 7000WX platform with its 128 PCIe Gen 5 lanes and 8-channel DDR5 memory? You'll need juice for that, and the In Win P250II is where you'll get it. From the company's PII line of ultra high-end PSUs, this jug puts out 2500 W under 200-240 VAC, or 1650 W under 115-240 VAC. It meets ATX 3.1 and PCIe 5.1 CEM specifications, and offers 80 Plus Platinum (EU 230 V) switching efficiency. The star attraction here is that the PSU puts out four 16-pin 12V2x6 connectors—this isn't using trickery such as converting PCIe connectors to 12V2x6, but native connectors on the PSU's backplane. Each of the four is capable of 600 W of continuous output, and excursions meeting the PCIe 5.1 CEM spec.

In Win didn't put out the power distribution table of this PSU, but we're not sure if it uses a single +12 V rail. Besides the four 12V2x6 connectors, it puts out five 6+2 pin PCIe power, two 4+4 pin EPS, a 24-pin ATX, and a dozen SATA power connectors. Next up, In Win introduced two new lines of fans, the LYNX LN120 series and the LYNX LN140 series. Both are stackable fans, and feature mechanical interlocks that allow you to join up to four of these at the hip, to minimize cable clutter. The interlock is based on the USB-C physical connector, which relays both 4-pin PWM and 3-pin ARGB pins. The LYNX LN140 turns at speeds between 900 and 1,800 RPM, pushing 44.57 to 89.14 CFM of airflow, at 0.77 to 3.07 mm H₂O static pressure, and 14 to 39 dBA noise output. Its sleeve bearing is rated for 30,000 hours. The LYNX LN120 turns along a wider speed range, of 900 to 2,200 RPM, pushing 25 to 65 CFM of airflow.
