Product Information

Full details

The Cooler Master V850 SFX Gold PSU is designed for builders of small form factor (SFF) mini-ITX PCs who need reliable, high-wattage power in a compact size. Its key benefit is delivering 850W of 80 PLUS Gold certified power with premium components and full-modularity, making it suitable for demanding builds. A potential caveat is its SFX form factor, which requires an adapter for use in standard ATX cases, although this adapter is included.

FAQs

What is the primary advantage of the SFX form factor?

The SFX form factor allows the power supply unit to be significantly smaller, making it ideal for compact PC cases such as mini-ITX builds where space is limited.

Can I use this PSU in a standard ATX case?

Yes, the V850 SFX Gold comes with an SFX-to-ATX mounting bracket that allows it to be installed in standard ATX power supply bays.

What does '80 PLUS Gold' certification mean?

It signifies that the power supply is highly efficient, typically operating at 90% efficiency or higher under common load conditions. This means less energy is wasted as heat, leading to lower electricity bills and reduced thermal output.

How does the 'fully-modular' design benefit me?

A fully-modular design means you only connect the cables you need for your specific build. This reduces cable clutter, improves airflow within the case, and makes the building process easier and cleaner.

Is the fan always on?

The V850 SFX Gold features a 92mm FDB fan with a semi-fanless mode. The fan will remain off under low loads for silent operation and will spin up as needed when the system's power demand increases.

What is the warranty period for this PSU?

The Cooler Master V850 SFX Gold comes with a 10-year warranty, reflecting its high-quality components and reliable design.

What type of capacitors are used?

This PSU uses 100% Japanese capacitors, which are known for their high quality, reliability, and long lifespan.

Troubleshooting

PSU does not power on the system

Verify all modular cables are securely connected to both the PSU and the motherboard/components. Check that the AC power cord is fully plugged into the PSU and a working wall outlet. Ensure the PSU's power switch is in the 'On' position.

System randomly shuts down

This could indicate an overload or overheating issue. Ensure the PSU's wattage is sufficient for your components. Check that all cables are properly seated and that the PSU fan is unobstructed and spinning. Monitor system temperatures.

Fans are noisy

At lower power draw, the fan may be in semi-fanless mode and only spin up under load. If noise is constant and loud, check for obstructions around the fan or consider if the system is drawing more power than expected for the current load.

Component not receiving power (e.g., GPU, SSD)

Confirm that the correct modular power cable for that specific component is used and securely connected. Try a different cable or a different connector on the PSU if available.
