Power supply DeepCool PS850G (850W) SFX Black PSU - R-PS850G-FE0B-JGEU

DeepCool PS850G is an 850W SFX power supply for compact but serious gaming and work configurations. The SFX format and length of only 100 mm allow you to fit it into small ITX cases without sacrificing power or stability. The 80+ Gold certification and efficiency ≥90% at 50% load mean less heat and quieter operation. You also get modern standards like ATX 3.1 and PCIe 5.1 with 12V-2x6 (16-pin) connector for the new generations of GPUs.

What you get

With a total power of 850 W and a strong +12 V rail with up to 70.8 A / 849.6 W, this PSU easily handles high-end GPUs and multi-core CPUs in the same build. The modular design gives you only the necessary cables, which is super important in SFF cases for better airflow and easier cable management. Active PFC + Half Bridge SRC LLC + DC-to-DC topology help for more stable voltages and higher efficiency under different load modes. The 92 mm FDB fan takes care of cooling and quieter operation, and Japanese electrolytic capacitors increase reliability in the long term. The official ATX 3.1 certification for 200% system and 300% 12V-2x6 instantaneous load (0.1 ms) is important if you plan a powerful GPU with aggressive power spikes.

• 850 W total power with +12 V: 70.8 A / 849.6 W, which is enough for a high-end GPU plus a powerful multi-core CPU in a compact build.
• SFX format with dimensions 125 × 100 × 63.5 mm and length of only 100 mm, suitable for mini-ITX and other small cases without compromising power.
• 80+ Gold certification and efficiency ≥90% at 50% load, meaning less heat loss and lower cooling load.
• ATX 3.1 and PCIe 5.1 support with 12V-2x6 (16-pin) connector for GPUs, ready for the latest graphics cards with high short-term peaks.
• Modular design with connectors: 1× 24-pin ATX, 2× 4+4 pin CPU, 2× 6+2 pin PCIe (single + dual cable), 1× 12V-2x6 PCIe 5.x, and cable with 3× SATA + 1× Molex for a clean and organized internal look.
• 92×92×20 mm FDB fan for quieter and more reliable operation in the long term, even under higher load.
• Full Japanese electrolytic capacitors, operation up to 40 °C and up to 5000 m altitude plus protections OPP, OVP, SCP, OTP, OCP, UVP, SIP, NLO for maximum component security.
• Cybenetics Platinum and PPLP Gold efficiency, which further confirms the real efficiency and acoustic behavior beyond the standard 80+ rating.

Who it's suitable for

This power supply is aimed at people building a compact but powerful gaming or creative configuration – mini-ITX or other SFF build with a modern GPU on PCIe 5.x. It's suitable if you want high power density, modern standard (ATX 3.1), and reliability without unnecessary noise. If you're aiming for a huge full tower with easier airflow and don't need the SFX form factor, you might have a wider choice with standard ATX PSUs.

The most sensible aspect here is the combination of SFX format, 850 W power, and official ATX 3.1 / PCIe 5.1 with 12V-2x6, reinforced with quality components and real high efficiency – exactly what you need for a serious, modern SFF build.
