The ASUS ROG Strix 1000W Platinum is a fully modular ATX 3.1 power supply for high-end gaming PCs and workstations using power-hungry modern graphics cards. It combines 80 PLUS Platinum efficiency, a PCIe Gen 5.1 16-pin cable, GPU-first voltage stabilization, and a 10-year warranty.
Recommended For
- High-end gaming PC builders using a modern power-hungry graphics card who want native ATX 3.1 and PCIe 5.1 support, including a 12V-2x6 cable, instead of relying on adapter cables.
- Enthusiast builders who prioritize clean cable management and a visually distinctive PC interior; the fully modular design, individually sleeved cables, and ROG styling suit showcase gaming builds.
- Users running demanding gaming or workstation workloads who value strong electrical performance, low ripple, thermal headroom, and a long replacement horizon supported by the 10-year warranty.
- Noise-conscious desktop users who spend much of their time at light or moderate loads and want semi-passive operation through ASUS 0dB fan mode, with fan noise becoming more relevant mainly during heavier loads.
Real-World Use Scenarios
- A user building a high-end gaming PC with a modern, power-hungry graphics card connects the GPU directly with the included 16-pin PCIe cable; the ATX 3.1 design and native 12V-2x6 connection provide a cleaner installation and are better suited to handling modern GPU power behavior than older adapter-based setups.
- A gamer uses the PC for web browsing, esports, or light gaming between intensive sessions; the 0dB mode can keep the PSU fan off at lower system loads, making the power supply effectively silent until the system demands more power.
- A user runs demanding games, rendering workloads, or CPU-and-GPU stress tests for extended periods; independent testing found strong voltage regulation, low ripple, and no thermal stress during high-load operation, so the system should remain electrically stable when properly sized for the build.
- A builder wants a clean-looking showcase PC with minimal unused wiring; the fully modular design and flexible individually sleeved cables let the user install only the required connections and route them more neatly behind the motherboard tray.
- A user upgrades from an older power supply while keeping a current high-end GPU platform; the included ATX 3.1-compatible 16-pin cable reduces the need for separate GPU power adapters, but the user still needs to confirm that 1000W is appropriate for the complete CPU, GPU, storage, and accessory configuration.

Reference Q&A
Q: Should I buy the ASUS ROG Strix 1000W Platinum or the ROG Strix 1200W Platinum?
A: Choose the ROG Strix 1000W Platinum for most high-end single-GPU gaming systems when 1000W provides adequate headroom. Choose the 1200W model for RTX 5090-class systems, heavily overclocked CPUs, sustained workstation workloads, or a larger future-upgrade margin. The 1200W version adds 200W of capacity but is only useful if the system can draw substantially more than the 1000W model can comfortably support. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-strix/rog-strix-1000p-gaming/spec/?config=90YE00W1-BTAA00&utm_source=openai))
Q: Is the ASUS ROG Strix 1000W Platinum worth choosing over a cheaper 1000W Gold PSU?
A: Choose the ROG Strix 1000W Platinum when you want higher certified efficiency, ATX 3.1 compliance, a native PCIe 5.1 16-pin cable, 0dB fan operation, and ASUS's GPU-First voltage-stabilization features. A 1000W Gold model is the more practical choice when the system has the same power requirement and the lower purchase cost matters more than the Platinum efficiency rating and premium features. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-strix/rog-strix-1000p-gaming/spec/?config=90YE00W1-BTAA00&utm_source=openai))
Q: Should I get the ASUS ROG Strix 1000W Platinum or the 850W Platinum model?
A: Choose the 850W Platinum model when the system's estimated peak consumption remains comfortably below 850W and no major GPU upgrade is planned. Choose the 1000W model for higher-power GPUs, enthusiast CPUs, frequent sustained workloads, or additional upgrade headroom. Both models belong to the same ROG Strix Platinum family, so the main decision is available wattage rather than a different feature class. ([press.asus.com](https://press.asus.com/news/press-releases/asus-rog-strix-platinum-psu-gaming-series-release/?utm_source=openai))
Q: How does the ASUS ROG Strix 1000W Platinum compare with the Corsair RM1000x?
A: Choose the ASUS when Platinum efficiency, ATX 3.1 support, a native 16-pin GPU cable, GPU-focused voltage sensing, and selectable 0dB operation are priorities. Choose the Corsair RM1000x when a current ATX 3.1 Gold-rated 1000W platform with low-noise operation is sufficient and you prefer Corsair's RMx ecosystem. Both are fully modular 1000W desktop PSUs, so the deciding factors are efficiency tier, feature set, cable design, and price at the time of purchase. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-strix/rog-strix-1000p-gaming/spec/?config=90YE00W1-BTAA00&utm_source=openai))
Q: Is the ROG Strix 1000W Platinum suitable for a compact PC build?
A: Choose the ROG Strix 1000W Platinum for a standard ATX case or a performance-first build where cable capacity, cooling, and upgrade headroom matter. For a small-form-factor case, choose an SFX-L unit such as the ROG Loki 1000W Platinum instead; the Strix measures 160 x 150 x 86 mm, while the Loki measures 125 x 125 x 63.5 mm and includes an ATX-to-SFX adapter bracket. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-strix/rog-strix-1000p-gaming/spec/?config=90YE00W1-BTAA00&utm_source=openai))
Q: Is this 1000W power supply suitable for a high-end gaming PC?
A: Yes. It is designed for high-performance systems with a 1000W maximum output, ATX 3.1 compliance, and a native PCIe Gen 5.1 16-pin cable. Whether 1000W is sufficient still depends on the specific CPU, GPU, storage, and overclocking configuration, so users should confirm their components' recommended PSU requirements. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-strix/rog-strix-1000p-gaming/spec/?config=90YE00W1-BTAA00&utm_source=openai))
Q: Does it include the cable needed for a modern graphics card with a 16-pin power connector?
A: Yes. The package includes one PCIe Gen 5.1 16-pin-to-16-pin cable, along with four PCIe 6+2-pin connectors. This supports graphics cards designed for a native 16-pin connection, while compatibility with a specific GPU should still be checked against that card's power requirements. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-strix/rog-strix-1000p-gaming/spec/?config=90YE00W1-BTAA00&utm_source=openai))
Q: Will this power supply fit in my PC case?
A: It uses a standard ATX power-supply form factor and measures 160 x 150 x 86 mm. It should fit cases that support standard ATX PSUs, but users should verify the case's maximum PSU length and cable-clearance requirements. It may not be suitable for proprietary OEM desktops or small-form-factor cases. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-strix/rog-strix-1000p-gaming/spec/?config=90YE00W1-BTAA00&utm_source=openai))
Q: What cables and connectors are included?
A: The fully modular package includes one 24-pin motherboard cable, two CPU cables, one PCIe Gen 5.1 16-pin cable, four PCIe 6+2-pin connectors, six SATA connectors, and three peripheral connectors. Because the cables are detachable, users can install only the connections their build requires. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-strix/rog-strix-1000p-gaming/spec/?config=90YE00W1-BTAA00&utm_source=openai))
Q: Is it quiet enough for a gaming PC?
A: It is designed for low-noise operation, with 0dB technology that can stop the fan during lighter loads and a Cybenetics Lambda A+ noise certification. The fan may still operate during higher system loads, so silent operation is not guaranteed during demanding gaming or rendering sessions. ([rog.asus.com](https://rog.asus.com/us/power-supply-units/rog-strix/rog-strix-1000p-gaming/spec/?config=90YE00W1-BTAA00&utm_source=openai))
Q: Is the ASUS ROG Strix 1000W Platinum a good choice for a high-end gaming PC?
A: Yes. It is best suited to high-end systems using powerful GPUs and CPUs because it provides 1000W, ATX 3.1 support, a native PCIe Gen 5.1 16-pin cable, and multiple legacy PCIe connectors. Reddit discussions commonly pair it with RTX 5080-, RTX 5090-, and Radeon 9070 XT-class builds.
Q: Is 1000W overkill for this power supply?
A: It can be overkill for midrange systems or builds with lower-power graphics cards, but it provides useful headroom for future high-end GPU upgrades. Reddit users specifically discuss choosing 1000W to avoid replacing the PSU when moving from an 850W-class system to a more demanding graphics card.
Q: Is the ASUS ROG Strix 1000W Platinum suitable for a future GPU upgrade?
A: Yes, provided the future graphics card and system remain within the PSU’s 1000W capacity. Its ATX 3.1 compliance and included PCIe Gen 5.1 16-pin cable make it appropriate for newer high-power GPU platforms, which is why Reddit users consider it for future RTX 50-series upgrades.
Q: Is this PSU a good option if low noise is important?
A: It is designed to operate quietly during light loads through ASUS 0dB technology, but fan noise under sustained gaming or stress loads remains an important trade-off to check in independent testing. A Hardware Busters review specifically discusses fan-bearing noise, so buyers prioritizing a quiet room should review load-noise results rather than relying only on the 0dB feature.
Q: What are the main trade-offs of choosing this power supply?
A: The main trade-offs are likely cost, physical fit, and capacity utilization. It offers premium 80 PLUS Platinum efficiency, ATX 3.1 support, fully modular cabling, and a 10-year warranty, but those features may be unnecessary for a modest gaming PC, and a 1000W unit can provide more capacity than the system actually needs.
