Lian Li Lian Li SP850 SFX Modular 80 Plus Gold Power Supply SP850B

The SP850 is an exceptional power supply produced by Lian Li. With its SFX form factor, the SP850 is ideal for the enthusiast... morewho needs a powerful PSU for an SFF build. With a maximum DC output of 850W, this PSU can supply even the most power-hungry components available today. Furthermore, it is extremely quiet, with a maximum fan volume of just 40.6 dB. It even boasts a zero RPM mode when operating at less than 40% load. Lian Li is so confident in the SP850's performance and reliability that they offer a 5-year limited warranty for peace of mind. Lian Li SP850 PSU at a Glance: Maximum DC output of 850W 80 Plus Gold rating - 91.55% efficient at half load SFX form factor, perfect for small builds Zero RPM mode under 40% load Fully modular design for minimal cable clutter PCIe 5.0 12-pin cable included Big Power in a Small Package Lian Li has managed to pack a large amount of power delivery into a small package with the SP850. Boasting an SFX form factor, the dimensions are 100mm x 63.5mm x 125mm (DxWxH), perfect for a small build. This PSU will be able to supply even the most powerful components available. The SP850 is able to achieve this by delivering 100W on its combined +3.3V and +5V rails, and 840W on its combined +12V rails. Quietly Efficient The Lian Li SP850 is an amazingly quiet power supply, and when under a full load, the cooling fan only reaches 40.6 dB. That's as quiet as a library! What's even better, the passive heat dissipation of this PSU is so effective that when under 40% load, the fan can enter a zero RPM mode for totally silent operation. The cooling potential of this power supply is possible thanks to the 91.55% efficiency at 115VAC at 50% load. Thanks to this capability, this PSU is able to achieve an 80 Plus Gold rating and only narrowly misses out on an 80 Plus Platinum rating. Fully Modular Design The Lian Li SP850 allows you to only use the cables you actually need, thanks to its fully modular design. This makes it feasible to construct extremely clean builds, free of cable clutter. Included with this PSU is a full range of modular cables, from the necessary motherboard and CPU cables to a range of PCIe, SATA, and peripheral cables. Alongside these standard cables, the SP850 also includes a PCIe 5.0 dual 8-pin to 12-pin cable, perfect for supplying power to modern GPUs without requiring an adapter.
