ASRock Steel Legend SL-1000P — 1000 W ATX 3.1, 80 PLUS Platinum, Fully Modular

1000 W80 PLUS PlatinumFully modularNative 12V-2x6

The ASRock Steel Legend SL-1000P is a 1000 W ATX 3.1 power supply with 80 PLUS Platinum certification and Cybenetics Platinum / LAMBDA A+ ratings, for high-end gaming PCs and workstations with one powerful graphics card. It delivers 83.4 A on the +12V rail, is PCIe 5.1 ready with a native dual-colour 12V-2x6 (12+4 pin) connector, and supports 200% total power excursion.

All cables are fully modular. A 135 mm striped axial FDB fan with switchable iCOOL mode keeps noise low, the capacitors are all Japanese 105 °C parts, and ASRock adds a built-in 5V Boost function and PCIe 5.1 Cable TempGuard. The unit measures 150 × 150 × 86 mm and carries a 10-year ASRock warranty.

Before you order: At 150 mm long it is deeper than many 140 mm units — check the PSU bay of compact ATX cases and leave space for the modular cable plugs.

What's in the Box

  • 1 × ASRock Steel Legend SL-1000P power supply
  • Modular cable set (connector counts below)
  • Other box contents are not listed by ASRock — ask us for confirmation

What It Means in Practice

  • 1000 W covers a single high-end GPU with a high-core-count CPU and leaves headroom for upgrades.
  • The native 12V-2x6 cable connects directly to current GPUs; Cable TempGuard is ASRock's temperature safeguard for that connector.
  • Nine SATA and three Molex connectors handle large storage builds.
  • iCOOL mode keeps the fan slow at lower loads; switch it off if you prefer constant airflow.

What Will Not Work

  • It has only one 12V-2x6 connector — for two modern GPUs, look at the SL-1200P.
  • It is not SFX and will not fit SFF cases that need SFX/SFX-L.
  • Modular cables are specific to this PSU — do not mix in cables from other units.
  • No RGB lighting or software monitoring.

Frequently Asked Questions

1000 W or 1200 W?
The SL-1000P suits one high-end GPU. Choose the SL-1200P if you need two 12V-2x6 connectors or more headroom for workstation loads.
What is Cable TempGuard?
ASRock's temperature safeguard for the PCIe 5.1 12V-2x6 cable, aimed at protecting the high-current GPU connector.
Can I reuse cables from my old PSU?
No — modular pinouts differ between brands and models. Use only the SL-1000P cables.
Singular Expert Insight · Buyer's Guide
