ASRock Steel Legend SL-850GW 850W ATX 3.1 Power Supply (White)
850W80 Plus GoldCybenetics PlatinumFully Modular
The ASRock Steel Legend SL-850GW is the white edition of ASRock's premium fully modular ATX 3.1 power supply, rated 850W with 80 Plus Gold and Cybenetics Platinum efficiency, built for white-themed high-end gaming PCs running PCIe 5.1 graphics cards. It carries part number 90-UXS085-GFEABA (EAN 4710483949067) and includes a native dual-color 12V-2x6 cable that delivers up to 600W directly to the GPU. Built with 100% Japanese capacitors and a 135mm striped axial FDB fan with iCool intelligent control, it earns a Cybenetics Lambda A+ noise rating and is backed by a 10-year warranty. Typically in stock with fast delivery across Cyprus.
Compatibility & installation
Complies with ATX 3.1 and PCIe 5.1. The included native dual-color 12V-2x6 (12+4 pin) cable connects directly to current-generation GPUs — seat it fully until it clicks; older cards use the three 8-pin (6+2) PCIe leads. Two 8-pin (4+4) EPS connectors cover modern motherboards. Fits any case taking a standard ATX PSU at 150 mm depth (150 × 150 × 86 mm). Use only the ASRock-supplied modular cables — third-party cables can differ in pin configuration and damage your hardware even if the connector physically fits.

Frequently Asked Questions
Singular Expert Insight
The Steel Legend SL-850GW brings the same strong value as the black SL-850G in a white finish: although rated 80 Plus Gold, it achieves Cybenetics Platinum efficiency and a Lambda A+ noise score, pairs 100% Japanese capacitors with a quality FDB fan, and is fully modular with a 10-year warranty — ideal for a clean, light-themed build. It is a clear step up from ASRock's value, non-modular Challenger line. Browse the full range of PC power supplies to compare efficiency and finishes.
Buyer's Guide
Buy it if
You want a white, fully modular 850W ATX 3.1 PSU with Cybenetics Platinum efficiency, Japanese caps and a 10-year warranty.
Skip it if
You prefer a black PSU (choose the SL-850G) or your build draws well under ~550W — a smaller unit costs less.
Also consider
The ASRock Challenger CL-750G for a cheaper non-modular option, or a 1000W unit for more headroom.
