Description
The InWin P-II series, specifically the P105II and P130II, represents a significant leap in power delivery for modern computing. Engineered to meet the Intel ATX 3.1 specification, these units are designed to handle the massive power excursions common in high-performance graphics cards. With an 80 PLUS Platinum certification, they offer up to 92% efficiency, reducing heat waste and electricity costs. The inclusion of a native 12V-2x6 cable ensures compatibility with the latest PCIe 5.1 hardware, providing up to 600W through a single connection.
This product is for:
- Hardcore gamers utilizing NVIDIA GeForce RTX 40-series or upcoming 50-series GPUs that require stable 12V-2x6 power delivery.
- Professional workstation users running multi-GPU setups for 3D rendering, AI training, or video production.
- PC enthusiasts and overclockers who demand tight voltage regulation and high-wattage headroom for system stability.
- Silent PC builders who benefit from the 135mm Fluid Dynamic Bearing (FDB) fan that operates under 25 dB(A) at 50% load.
- Long-term system builders looking for a future-proof investment backed by a comprehensive 10-year manufacturer warranty.

Integrating the InWin P-II series into a build is streamlined by its fully modular design and flexible flat cables. The 150mm depth makes it compatible with most mid-tower cases while leaving ample room for cable management. During high-load scenarios, the active PFC and high-quality SECC steel construction ensure the unit remains cool and quiet. The transition to ATX 3.1 means the PSU can handle power spikes up to 200% of its rated capacity, preventing the sudden shutdowns often seen with older power standards when paired with modern high-TDP components.
Compared to standard ATX 3.0 power supplies, the InWin P-II series adheres to the updated ATX 3.1 and PCIe 5.1 standards, featuring the improved 12V-2x6 connector which offers better thermal performance and a more secure fit than the original 12VHPWR design. While Gold-rated units are common, the Platinum efficiency of the P-II series results in lower internal temperatures and a longer lifespan for internal capacitors. Its compact 150mm length also provides a significant advantage over longer 180mm or 200mm high-wattage units that often struggle to fit in modern chassis.
Q&A:
- What is the difference between ATX 3.0 and ATX 3.1 in this PSU? The InWin P-II series follows ATX 3.1, which introduces the 12V-2x6 connector for improved safety and power delivery reliability compared to the older 12VHPWR standard.
- Does this power supply support the RTX 4090? Yes, both the 1050W and 1300W models include native 12V-2x6 cables capable of delivering 600W, making them ideal for high-end cards like the RTX 4090.
- How quiet is the fan during operation? The 135mm FDB fan is designed for silent operation, maintaining noise levels below 25 dB(A) even at 50% load, ensuring a quiet computing environment.
- Is the 10-year warranty global? InWin provides a 10-year warranty that covers defects in materials and workmanship, reflecting the high-grade components used in the Platinum-rated P-II series.
- Can I use this PSU in a small form factor case? While it is a standard ATX PSU, its 150mm length is relatively compact for its wattage class, allowing it to fit in many compact ATX cases that might reject larger 1300W units.
