Last year, ASRock took a bold step into the power supply unit (PSU) market, surprising many with its new lineup aimed at a wide range of PC users. Known for expanding its product range with gaming monitors and Mini PCs, ASRock’s entry into the PSU arena brings more choices for consumers—something always welcomed in the competitive PC industry.
Among its offerings is the ASRock SL-1200GW, part of the Steel Legend “Mainstream Durable” series. This 1200W model is an upgrade from the previously tested SL-1000G, providing more power for those who need it.
The ASRock Steel Legend series caters to mainstream enthusiasts and offers wattages ranging from 650W to 1200W, with options extending up to 1650W in their premium Taichi and Phantom Gaming series. Our focus, the 1200W unit, features a fully modular design.
Key specifications of the SL-1200GW include a maximum DC output of 1200 Watts, active PFC, and an 80 PLUS Gold certification. It boasts over 90% efficiency, complies with Intel’s C6 & C7 power states, and operates in temperatures from 0-50°C. Highlights include:
– 80 PLUS Gold and Cybenetics Platinum certified
– ATX3.1 and PCIe5.1 readiness
– Fully modular cable design
– High-quality Japanese capacitors
– 135mm Striped Axial FDB Fan
– iCool Intelligent Fan Control Mode
– Built-in 5V Boost function
Protection features abound, including safeguards against over-voltage, under-voltage, over-power, over-temperature, over-current, and short circuits.
The compact design fits an ATX form factor measuring 150 x 86 x 150 mm, cooled by a top-mounted 135mm fan with a semi-passive operation, controllable via iCool software. Available in black or white, it comes with a 10-year warranty and is priced competitively at $179.99.
The unit shines with a range of connectors: five 8-pin for CPU/PCIe, two PCIe 12+4 (12V-2×6), an ATX 24-pin, and three 6-pin connectors for peripherals. Cables include an ATX 20+4 pin, Gen5 (12V-2×6), and various CPU and PCIe connectors, facilitating versatile builds.
ASRock’s dual-tone 12V-2×6 power connector ensures secure connections, with high-quality cables featuring 16 AWG UL4411/UL3266 wires. The iCool button on the back enhances cooling control, while the 135mm FDB fan ensures efficient heat management.
Internally, the PSU relies on HEC components, and Infineon and Champion units for APFC functions—showcasing decent soldering quality and build integrity.
ASRock’s recent venture into PSUs has shown commendable quality and adherence to the latest standards. Having dual 12V-2×6 power connectors is a boon for AI workstations or high-end GPU setups. The refreshed design and efficient cooling make it appealing, with its pricing paralleling other 1200W options in the market. For high-end PC builds, ASRock presents a compelling choice.
