This article covers Asus ROG Strix 1000W プラチナ ホワイト PSU.

Overview

The ASUS ROG Strix 1000W Platinum White PSU (model ROG-STRIX-1000P-GAMING-WHITE) is a high-end power supply designed for enthusiast gaming PCs. It carries the 80 PLUS Platinum certification and fully supports the ATX 3.1 standard, including a native 12V-2x6 connector for the latest GeForce RTX 40-series and beyond graphics cards. The standout feature is the adoption of GaN (Gallium Nitride) MOSFETs, which replace traditional silicon MOSFETs, delivering up to 30% better power efficiency and allowing for a cleaner internal layout with reduced heat generation. Another key innovation is the patented "GPU-FIRST" voltage sensing technology, which increases voltage delivery to the graphics card by up to 45%, ensuring stable power during demanding gaming sessions. This helps reduce frame-time stuttering and improves overall system stability. The large ROG heatsink covers critical components, keeping temperatures lower than reference designs, while the 135mm dual-ball bearing fan offers a 0dB fan mode that stops the fan completely under light loads, making it virtually silent for everyday tasks. The unit is fully modular, allowing you to connect only the cables you need, which simplifies cable management and improves airflow. The white color scheme is perfect for builders who want a clean, coordinated look in their system.

Compatibility Guide

This PSU uses the standard ATX form factor (150mm wide, 160mm deep, 86mm high) and fits in most ATX and Micro-ATX cases. However, the 160mm depth may be tight in some compact cases, so always check your case's PSU clearance before purchasing. Connectors: 24-pin ATX, EPS 12V 8-pin (4+4)×2, PCIe 5.0 12V-2x6 (600W capable), PCIe 8-pin (6+2)×4, SATA×12, Peripheral 4-pin×4, FDD adapter Standards: ATX 3.1, EPS 12V v2.92 Efficiency: 80 PLUS Platinum (92% at 115V, 94% at 230V) Protections: OCP, OVP, UVP, SCP, OTP, OPP This 1000W unit easily handles a high-end configuration like an Intel Core i9-14900K or AMD Ryzen 9 7950X paired with an RTX 4090 or RTX 5090 (expected). The native 12V-2x6 connector means no adapter is needed for the latest NVIDIA cards.

Product Info

The ASUS ROG Strix 1000W Platinum White PSU was released in late 2025 and sits firmly in the high-end tier. Its 80 PLUS Platinum certification and GaN MOSFETs give it a 2-3% efficiency advantage over 80 PLUS Gold competitors in the same wattage class. The unit comes with a 10-year manufacturer warranty, reflecting its long-term reliability. Rated output: 1000W (single +12V rail: 83.3A / 1000W) Efficiency: 80 PLUS Platinum ATX version: 3.1 12VHPWR connector: Native 12V-2x6 Modular design: Fully modular Fan: 135mm dual-ball bearing Noise level: ~25 dBA max (silent in 0dB mode) Dimensions: 150×160×86mm Weight: ~2.5kg Color: White

Best Use Cases

High-End Gaming Builds If you're building a system with a flagship GPU like the RTX 4090 or RTX 5090 paired with a top-tier CPU, this PSU is an excellent choice. The 1000W capacity provides ample headroom, and the GPU-FIRST voltage sensing ensures stable power delivery under heavy loads, reducing stutter in demanding games at 4K or VR. However, if you're using a mid-range GPU like an RTX 4060, this unit is overkill and you may save money with a 750W or 850W unit. ### Silent PC Enthusiasts The 0dB fan mode makes this PSU completely silent under light to moderate loads. The large heatsink and GaN MOSFETs keep temperatures low, so the fan rarely spins up during normal desktop use or light gaming. This is ideal for those who work late at night or need a quiet recording environment. Note that under sustained heavy loads, the fan will spin audibly, though it's still relatively quiet. ### White-Themed Builds The white chassis and fully white modular cables make it a perfect match for a white-themed PC. You don't need to buy custom cables to achieve a clean look.

Things to Consider

This PSU is priced significantly higher than a standard 80 PLUS Gold 1000W unit. If budget is a concern, consider the non-Platinum ROG Strix 1000W Gold model or a Seasonic Focus Plus Gold 1000W. The benefits of GaN MOSFETs are most noticeable under heavy loads; for typical desktop use, the difference may not be apparent. Check your case's PSU clearance: the 160mm depth might be a tight fit in some compact ATX cases. Also, while 1000W is sufficient for single-GPU flagship builds, if you plan to run dual GPUs or a workstation with continuous high load, consider a 1200W+ unit. ## FAQ
Q: Is this PSU compatible with ATX 3.0 motherboards? A: Yes, ATX 3.1 is backward compatible with ATX 3.0. The 12V-2x6 connector is an improved version of 12VHPWR and works with all current NVIDIA RTX 40-series cards without adapters. Q: Are there other color options besides white? A: This model is exclusively white. A black version is available under the model ROG-STRIX-1000P-GAMING (without the "WHITE" suffix). Q: Does it come with all white ca
