The ASRock PRO-1000G is a 1000W, 80 PLUS Gold, non-modular ATX 3.1 power supply with a native 12V-2x6 connector, suited to desktop builders powering a high-performance GPU and other demanding components.
Recommended For
- Builders of a high-end single-GPU gaming PC who need up to 1000 W and a native 12V-2x6 cable; check the CPU/GPU combination against ASRock’s wattage guide.
- Value-focused PC builders who want an ATX 3.1, 80 PLUS Gold power supply and are comfortable with permanently attached cables.
- Builders who want a straightforward 1000 W PSU for a demanding gaming or creator system with several storage drives and multiple PCIe power connections.
- PC builders who prefer a compact-length ATX power supply for a standard ATX case with limited PSU depth; the unit is 140 mm long.
Real-World Use Scenarios
- Building a high-end gaming PC around an RTX 5090 and a standard desktop CPU? ASRock’s guide recommends 1000 W for those CPU categories, so this PSU matches that guideline; check the exact CPU and full system configuration before buying.
- Upgrading to a graphics card with a 12V-2x6 power input? The native cable connects directly, and its dual-color connector is designed to make it easier to check that it is fully seated.
- Planning a high-end GPU build with room for added drives and cooling? The 1000 W capacity can suit systems whose CPU-and-GPU combination calls for up to 1000 W under ASRock’s guide; the guide notes that recommendations include other components, so check the specific configuration.
- Assembling a desktop with several SATA drives? The six SATA power connectors can serve multiple storage devices without relying on SATA power adapters, provided the drives’ locations work with the fixed cable layout.
- Replacing a PSU in a standard ATX case with limited PSU-bay depth? Its 140 mm length may help with fit, but the non-modular cables stay attached, so allow space to route unused leads.
