Western Digital Ultrastar DC SN650 7.68TB U.3 15mm PCIe Gen4 NVMe 1.4b

The CORSAIR CP-9020252-NA is an 850 watt power supply from the RM850x SHIFT family, created for builders who want dependable power and easier cable routing. It follows the ATX 12V Version 3.0 standard and holds an 80 PLUS Gold efficiency rating, minimizing wasted energy while delivering steady current to demanding hardware.

A patent pending side cable interface moves every connector to the outer face of the unit. Once the supply slides into an ATX case, you can reach each port without leaning over the motherboard. This layout helps anyone who values a clean interior, needs quick access for upgrades, or simply wants less hassle when closing the side panel.

The design is fully modular, so only the required cables stay in the system. Four PCIe connectors cover multi-cable graphics cards or additional expansion cards, while a dedicated 12VHPWR lead supports NVIDIA GeForce RTX 40 series GPUs. Twelve SATA and eight PATA connectors power large banks of drives, fans, and accessories, making the unit suitable for gaming rigs, editing workstations, and storage-heavy builds.

The 80 PLUS Gold certification delivers up to 90 percent efficiency at typical loads. When the system idles, a 140 mm fluid dynamic bearing fan enters Zero RPM mode and stops completely, keeping the PC quiet during web browsing or office work. Under higher demand, the fan spins up smoothly to move air without adding excessive noise.

Inside, 100 percent industrial grade 105 °C Japanese electrolytic capacitors help maintain stable voltages and extend service life. Outside, the standard ATX footprint lets the RM850x SHIFT fit into most mainstream cases with no special brackets. Whether you are finishing a high-end gaming build, refreshing an older tower, or assembling a professional workstation, this power supply offers a practical mix of efficiency, accessibility, and long-term reliability.
