Power Supply Corsair RMe RM850e White 850W 80+ Platinum ATX 3.1, Thermal Protect - CP-9020338-EU

The Corsair RMe RM850e White is an 850W ATX power supply unit in white, aimed at mid–range to high-end gaming and creative builds. It combines high efficiency with 80+ Platinum / Cybenetics Platinum ratings and a modern ATX 3.1 design, ensuring your build is ready for the next generation of GPUs. The fully modular design and compact length of 140 mm make it convenient for smaller cases and clean cable management. Add to this the special 12V-2x6 cable with ThermalProtect protection for the GPU, and you get a power supply that is both practical and well-protected.

What you get here: a real 850 W output power with 92 % efficiency, which means less heat loss and lower noise under typical gaming or rendering loads. ATX 3.1 / PCIe 5.1 support and the 12V-2x6 connector guarantee compatibility with modern and future graphics cards, without the need for adapters. The ThermalProtect feature in the 12V-2x6 cable monitors the connector temperature and protects the GPU from overheating – especially valuable for more powerful cards that draw a lot of current. The Zero RPM mode of the 120 mm fan allows for completely silent operation under light loads, while the 105°C-rated capacitors and the full set of protections (OVP, OTP, UVP, SCP, OCP, OPP) reduce the risk of long-term issues. Modern Standby support, in turn, provides faster system wake-up and better consumption in idle.

• 850 W output power is sufficient for powerful gaming and work configurations with a modern high-end GPU and many storage devices.
• ATX 3.1 certified, PCIe 5.1 compatible power supply, ready for current and next-generation graphics cards without additional adapters.
• 12V-2x6 PCIe 5.1 600W cable with ThermalProtect provides stable power delivery and protection against connector overheating directly to the GPU.
• 80 PLUS Gold; Cybenetics Platinum, Cybenetics Noise A ratings indicate very high efficiency and low noise levels in real-world use.
• Fully modular (fully modular) design and debossed low-profile Type 4 cables help achieve a clean case interior and better airflow.
• Zero RPM mode of the 120 mm fan stops the fan blades under low load for completely silent operation in idle and light tasks.
• Compact dimensions 140 x 150 x 86 mm and weight 1.53 kg facilitate installation in smaller ATX cases without sacrificing power.
• High-quality 105°C-rated capacitors and MTBF 100 000 hours provide reliability for a long operating period, including at higher temperatures.
• Full set of protections – OVP, OTP, UVP, SCP, OCP, OPP protects your components from overvoltage, overload, short circuit, and overheating.
• Modern Standby support ensures faster system wake-up and better efficiency in low-power modes.

This power supply is suitable if you are building a serious gaming or work PC with a modern graphics card and want headroom for a future upgrade to a more power-hungry GPU. It also fits well for quieter builds where the Zero RPM mode and Cybenetics Noise A rating matter. If you are aiming for an ultra-budget computer or a very low-power system, 850W and this class of efficiency might be an unnecessary luxury.

The most meaningful aspect here is the combination of ATX 3.1 / PCIe 5.1 readiness, ThermalProtect for the 12V-2x6 connector, and high efficiency, all packed into a compact, fully modular, white chassis. You get a power supply that is adequate for today's high-end components and will not hold you back when you swap your GPU next.
