The ASUS ROG Strix 1000W Platinum is a fully modular ATX 3.1 power supply for high-performance gaming PCs and workstations, offering 1000W, PCIe 5.1 support, a native 12V-2x6 GPU cable, GPU-First voltage stabilization, and a 10-year warranty.
Recommended For
- High-end gaming PC builders using current flagship GPUs who want an ATX 3.1 PSU with a native 12V-2x6 cable, including systems built around GeForce RTX 50-series or Radeon RX 9000-series graphics cards.
- Quiet gaming and workstation users who regularly run demanding loads but prefer a PSU that can remain fanless during lighter use and stay relatively quiet under higher loads.
- Premium custom-PC builders who value fully modular cabling, a refined visible-build aesthetic, and long-term component support more than minimizing the purchase price.
- PC owners planning future GPU upgrades who want a high-efficiency, fully modular 1000W platform backed by a 10-year warranty instead of replacing the PSU with their next major build upgrade.
Real-World Use Scenarios
- A user building a high-end gaming PC with a current-generation graphics card uses the PSU’s native 12V-2x6 cable to avoid separate GPU adapters; the build has a cleaner power connection and is prepared for modern GPU power requirements.
- A gamer plays demanding titles for extended sessions on a high-end GPU; testing indicates strong voltage regulation and low ripple, so the system is likely to maintain stable power delivery without the PSU becoming a major thermal bottleneck.
- A user wants a quiet gaming or everyday PC and enables 0dB mode; during light workloads and lighter gaming, the PSU fan can remain stopped, reducing one source of system noise.
- A PC enthusiast upgrades an existing system or assembles a new enthusiast build with multiple CPU and PCIe power connections; the fully modular design lets the user install only the cables needed, making routing and cable management easier.
- A user runs a high-end gaming, rendering, or workstation PC under sustained load; the 1000W capacity and tested thermal performance provide operating headroom, while the fan ramps up gradually as demand increases rather than running continuously at full speed.

Reference Q&A
Q: Is the ASUS ROG Strix 1000W Platinum better than the Corsair RM1000x SHIFT?
A: Choose the ASUS ROG Strix 1000W Platinum if you want 80 PLUS Platinum efficiency, a compact 160 mm PSU length, and a conventional rear-mounted modular layout. Choose the Corsair RM1000x SHIFT if your case supports side-mounted PSU connectors and easier side cable access is more important than the ASUS model’s higher efficiency certification. Both provide 1000W capacity, full modular cabling, ATX 3.1 compliance, and a native PCIe 5.1 12V-2x6 cable.
Q: Should I buy the ASUS ROG Strix 1000W Platinum or the ROG Strix 850W Gold Aura Edition?
A: The ROG Strix 850W Gold Aura Edition is sufficient for many single-GPU gaming PCs and offers the same 10-year warranty, fully modular design, and 16-pin GPU power support. Choose the 1000W Platinum model when you are pairing a high-end GPU with a power-hungry CPU, want more upgrade headroom, need ATX 3.1 and PCIe 5.1 support, or prefer higher Platinum efficiency. The 1000W model is also shorter at 160 mm, compared with 180 mm for the 850W Gold Aura Edition.
Q: Is the ROG Strix 1000W Platinum enough for an RTX 5090?
A: For an RTX 5090 system, the ASUS ROG Strix 1200W Platinum is the more appropriate choice because ASUS recommends 1200W or higher for the RTX 5090. The 1000W Platinum model is more closely aligned with RTX 5080-class systems, for which ASUS recommends 1000W or higher, although the required wattage still depends on the CPU, overclocking, and the rest of the build.
Q: How does the ASUS ROG Strix 1000W Platinum compare with the older ROG Strix 1000W Gold Aura Edition?
A: The 1000W Platinum model is the stronger choice for a new high-end build because it upgrades the platform from ATX 3.0 and PCIe 5.0 support to ATX 3.1 and PCIe 5.1, adds a native 12V-2x6 cable, and uses an 80 PLUS Platinum efficiency rating instead of Gold. The older 1000W Gold Aura Edition remains suitable when its RGB lighting, larger connector count, or lower sale price matters more than the newer platform standard and efficiency rating.
Q: Is the ASUS ROG Strix 1000W Platinum a good choice for a compact ATX gaming PC?
A: It can work well in a compact ATX build because its 160 mm length is shorter than several conventional high-wattage ATX units, and its modular cables reduce unused cable volume. It is still a full-size ATX PSU rather than an SFX model, so case compatibility and clearance around the PSU cables must be checked before buying. Its 1000W output makes it more suitable for performance-focused compact systems than for ultra-small or portable builds.
Q: Does this power supply include the cable needed for a newer graphics card?
A: Yes. It includes a dedicated 16-pin 12V-2x6 PCIe cable for compatible newer graphics cards, along with four traditional PCIe 6+2-pin connectors. Verify your GPU's required connector and power rating before installation.
Q: Will this 1000W power supply be enough for a high-end gaming PC?
A: It is suitable for many high-performance gaming PCs and provides up to 1000 watts through a single 12V rail rated at 83.3A. Actual suitability depends on the graphics card, processor, overclocking, and other installed components, so check the system's recommended PSU rating.
Q: Will it fit in my PC case?
A: The unit measures 160 x 150 x 86 mm and uses the standard ATX power-supply form factor. Check your case's PSU-length limit, cable-routing space, and clearance behind the PSU before buying.
Q: Is this power supply quiet during normal use and gaming?
A: It is designed for low-noise operation, with a Cybenetics Lambda A+ noise certification rated below 20 dB and 0dB technology that can stop the fan during light loads. Fan behavior will vary with system load, temperature, and airflow.
Q: Is it fully modular, and does it include all the main cables?
A: Yes. It is fully modular, so only the cables required by the build need to be connected. The package includes motherboard, CPU, 12V-2x6 GPU, PCIe 6+2-pin, SATA, and peripheral cables; do not mix modular cables from another power supply.
Q: Is the ASUS ROG Strix 1000W Platinum worth buying over a cheaper 1000W PSU?
A: It is most suitable for buyers who value Platinum efficiency, ATX 3.1 support, a native 12V-2x6 cable, low-noise operation, and a 10-year warranty. Reddit discussions indicate that comparable lower-priced 1000W PSUs can provide similar core power capacity, so the ASUS model may be difficult to justify if price is the main priority.
Q: Who is the ASUS ROG Strix 1000W Platinum suitable for?
A: It is intended for high-performance gaming PCs and workstation-style builds that need up to 1000W, particularly systems using demanding modern GPUs. Its ATX 3.1 design, PCIe 5.1 support, native 12V-2x6 connector, single 12V rail, and 83.3A 12V output make it a stronger fit for high-end builds than for basic or midrange systems.
Q: Are the 18 AWG cables and long cable lengths a problem?
A: The community discussion did not identify the included 18 AWG wiring or its longer-than-typical lengths as a confirmed safety or performance problem. The PSU includes 1000 mm CPU cables and 750 mm PCIe cables, which can help with large cases but may require more cable management.
Q: Can I use custom cables or RGB extensions with the GPU-First feature?
A: Custom cables are available for this PSU, but compatibility with the GPU-First sensing feature depends on whether the replacement GPU cable includes the additional sensing connection. Reddit and CableMod discussions indicate that standard custom GPU cables may not carry that feature, while RGB extension cables do not change how GPU-First voltage sensing operates.
Q: Is the ASUS ROG Strix 1000W Platinum quiet enough for a gaming PC?
A: It is designed for low-noise operation, with a Cybenetics Lambda A+ rating, a stated noise level below 20 dB, and 0dB fan technology for light loads. Community discussion also mentions an audible shutdown tick on at least one unit, so buyers who require completely silent switching sounds should treat that as a possible trade-off rather than assume silence in every operating condition.
