DeepCool PS850P PSU SFX 3.1 1000W 80 Plus Platinum, ITX, Full Modular

DeepCool PS850P is a compact SFX power supply with 850W power, aimed at more serious ITX and small form factor builds with a powerful GPU. Despite its small size, the power supply offers an 80+ Platinum certification and up to 92% efficiency, which means less heat loss and quieter operation under load. Thanks to support for ATX 3.0/3.1 - PCIe Gen 5.0/5.1 and the included PCI-E 5.1 connector, you are ready for modern graphics cards without the need for adapters. The SFX format and a length of only 125 mm make it particularly convenient for compact cases.

What you get

With real 850W available and output lines of DC 3.3/5/±12 V, this power supply easily handles a combination of a powerful CPU + high-end GPU in ITX format. The 80+ Platinum certification with up to 92% efficiency means lower load on the electrical grid and less energy lost as heat — crucial for small cases with limited airflow. The fully modular design allows you to use only the necessary cables, reducing cable clutter and improving airflow. A 92 mm fan takes care of cooling, and in combination with high efficiency, helps the fan not to spin unnecessarily fast under partial load. The added PCI-E 5.1 and three PCI-Express 6+2 pin connectors provide enough flexibility for modern and future GPU configurations.

• Power 850W – sufficient for high-end GPU and powerful CPU even in compact ITX systems.
• 80+ Platinum certification and up to 92% efficiency – less loss, lower temperatures, and quieter operation under load.
• SFX format and dimensions 100 x 125 x 63.5 mm – ideal choice for small cases and SFF/ITX builds with limited space.
• Full modularity – connect only the cables you need for a cleaner build and better airflow.
• ATX 3.0/3.1 - PCIe Gen 5.0/5.1 support – ready for modern and future graphics cards without the need for additional adapters.
• PCI-E 5.1 x 1 and PCI-Express 6+2 pin x 3 – enough connectors for one powerful GPU or several more moderate cards as needed.
• 6 x SATA and 2 x Molex – flexibility for SSDs, HDDs, fans, and additional accessories in the system.

Who it is suitable for

PS850P is a logical choice if you are building a compact ITX or other SFF configuration with a powerful graphics card and do not want to compromise on power supply quality. It is suitable for gaming, creative work, and any demanding systems that need to fit in a small case. If you are aiming for a super budget build with low consumption, this power and class may be more than you need.

The combination of high power, SFX format, and 80+ Platinum efficiency makes DeepCool PS850P a very sensible choice for a serious small build. You get a compact, modern, and well-cabled PSU that easily handles today’s and tomorrow’s components.
