What to know before buying
- The listing identifies the unit as ATX and gives dimensions of 16 x 15 x 8.6 centimetres. Check available case clearance and whether the case layout provides access to side-mounted PSU connections before buying. The 140 mm fan, zero-RPM mode, Cybenetics Gold claim and ATX 3.1/PCIe 5.1 positioning are listing claims, not independently verified here.

Customer feedback reports positive impressions of quality and functionality, with quiet running and the zero-RPM mode also mentioned favourably. For a PC build where low-load fan noise matters, those reports may be relevant, though they do not establish measured noise levels or performance. The overall rating distribution is mostly five-star, with a smaller spread across lower ratings, so the positive picture is not universal.
Positive themes
- Customers describe the unit as good quality and functional.
- Feedback appreciates quiet operation and the zero-RPM mode.
