What reviewers say

  • Tom’s Hardware reviews the Asus ROG Strix 1000W Platinum as a high‑performance, visually striking power supply that delivers excellent electrical and thermal performance. The unit justifies its steep price with premium components, extensive customization options, a 10‑year warranty, low noise levels, full protection features, flexible modular cabling, outstanding power quality, and remarkable efficiency for its class, though some design choices are more aesthetic than practical.

  • KitGuru’s review of the Asus ROG Strix 1000W Platinum ATX v3.1 PSU highlights its high efficiency thanks to GaN MOSFETs, a fully modular design, and robust build quality with large heatsinks and dual ball‑bearing fans. The unit is praised for its low noise (including 0dB technology), strong voltage stability via ASUS’s intelligent stabilizer, and future‑proof PCIe 5.0 readiness. With an 80 PLUS Platinum rating and a 10‑year warranty, the review rates it 9/10, noting that the price (£240) reflects its premium features.

  • The review discusses the Asus ROG Strix 1000W Platinum’s use of GaN MODFETs and an extra voltage‑sensing system that, according to Asus, should improve GPU performance and gameplay smoothness. The author notes that while the PSU incorporates these technologies, it relies on a Champion CM6502UHHX controller for its APFC converter, which may not fully exploit the GaN FETs’ potential for higher efficiency. Overall, the review evaluates the design’s theoretical advantages but expresses uncertainty about whether the claimed benefits are realized in practice.

  • Gaming PC Guru gives the ASUS ROG Strix 1000W Platinum a thumbs‑up as a high‑end, fully modular PSU that delivers excellent 80 Plus Platinum efficiency, advanced ATX 3.1 and PCIe 5.1 support, and a clean design with ARGB lighting. The review praises its robust build quality, low noise levels, and the inclusion of a GPU‑First Intelligent Voltage Stabilizer for stable power delivery to demanding GPUs. It notes that the unit is priced on the higher side but justifies the cost with its performance, longevity (10‑year warranty), and future‑proof features.

Our take

Based on 4 reviews

Three of the four reviews agree the ROG Strix 1000W Platinum delivers excellent efficiency, low noise, and premium build quality with an 80 PLUS Platinum rating and 10-year warranty. Tom's Hardware, KitGuru, and Gaming PC Guru all highlight its strong electrical performance, robust construction, and quiet operation, justifying its premium positioning.

KitGuru and Gaming PC Guru praise its future-proof PCIe 5.1 support and voltage stabilizer, while Tom's Hardware calls the design visually striking but questions some practical choices. HWBusters expresses uncertainty about whether the GaN MOSFETs fully exploit their potential, suggesting buyers should verify real-world gains before paying the premium price.

Pros

  • 80 PLUS Platinum efficiency
  • Low noise with 0dB technology
  • 10-year warranty
  • Future-proof PCIe 5.1 support

Cons

  • Questions over GaN MOSFET practical benefits
  • Premium price
  • Some design choices prioritize looks over utility

Best for: High-end builders seeking maximum efficiency and quiet operation; budget buyers should look elsewhere.
