Pros & Cons

Pros

  • ✓ 850W in SFX footprint fits mini-ITX and SFF cases
  • ✓ 90-degree 12V-2x6 connector bends flat in tight side-panel clearance
  • ✓ ATX 3.1 compliant, delivers up to 600W to a single GPU

Manufacturer description

The Cooler Master V850 SFX Gold packs 850W of 80 PLUS Gold power into an SFX chassis built for mini-ITX and small-form-factor systems, so you can drop a full-height graphics card into a case the size of a shoebox without derating your build. It ships ATX 3.1 ready with a 90-degree 12V-2x6 connector rated to deliver up to 600W to a single GPU, and the right-angle exit is the detail that matters in SFF: the cable bends flat against the side panel instead of fighting the glass. Cooler Master builds it around Japanese capacitors, a full-bridge LLC topology with an integrated transformer and…

Cooler Master's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Will the Cooler Master V850 SFX Gold power an RTX 5090 or other 600W GPU?

It ships with an ATX 3.1 12V-2x6 cable rated to deliver up to 600W to the graphics card, which covers current single-connector GPUs. Confirm your specific card's total system draw against the 850W rating before buying.

Does it fit a standard SFX bay, or do I need SFX-L clearance?

It is an SFX-form-factor unit designed for mini-ITX and small-form-factor cases. Check your case's PSU spec for SFX support and verify the manufacturer's listed dimensions against your bay.

Why does the 12VHPWR connector come out at a 90-degree angle?

The right-angle design routes the cable flat against the case rather than forcing a tight bend, which Cooler Master cites as improving electrical durability and safety. In SFF builds it is often the difference between closing the side panel and not.

Are the included cables long enough for a mid-tower build?

They are cut to SFF-optimized lengths to cut clutter, and Cooler Master notes that extended cables may be needed for larger cases. Plan on buying extensions if you are using an SFX-to-ATX bracket in a full-size chassis.

How loud is it under load?

Cybenetics rates it A- for noise alongside its Gold efficiency certification, which is a strong result for an SFX unit. Small-form-factor supplies use smaller fans than ATX units, so expect audible ramp-up during sustained high-wattage sessions.

What warranty does Cooler Master offer on this unit?

Cooler Master lists a 10-year warranty on the V SFX Gold series. Check the product listing for current terms and registration requirements in your region.
