Cooler Master V SFX GOLD 850 ATX 3.0 Power Supply Review

Conclusion and Verdict

I can’t believe what I’m seeing here. How it is possible that a compact SFX power supply, no bigger than a couple of cans of Coke/Pepsi, can easily power a complete system with high-end PC components? That’s just crazy!

Measuring just 100 x 125 x 63.5mm, it’s one of the smallest PSUs we’ve tested in our labs. And it’s perfect for any mini-ITX systems, or custom PC builds (such as a special modding project), that require a solid, reliable and compact power supply supporting the 12VHPWR connector and ATX 3.0 standards.

For our test rig, we used an Intel Core i9-14900K processor, which has a Turbo Boost TDP of 253W+, along with the GeForce RTX 4080 SUPER with a TBP of up to 320W. At 100% load, just these two components alone consumes a lot of power.

During our AIDA64 full load tests, the +12V line on the PSU dropped from 12V idle to 11.094V at load. A small change of only -0.096V. Nothing to be concerned about, but I would watch this carefully. If that 12V line drops below 11V … then we might have a problem.

For the +5V line, it dropped from 4.96V to 4.920 (-0.04 difference) and for the +3.3V line, it also dropped from 3.312V to 3.264 (-0.048 difference).

Although all 3 voltage lines did drop during 100% full load, I’m still pretty happy with the performance, stability and reliability of the power supply, so no real complaints here.

I love the flat modular cables as it allows for easy cable management, plus it allows me to use the only cables I need. However, the cables are a little shorter than I expected, and this could a problem for larger ATX cases.

The power supply does not come with any RGB nor does it feature any Smart Zero fan on/off switch. There’s a sticker covering the power socket. It states that the fan does not spin until a specific core temperature is reached. What that temperature is … is not mentioned.

The power supply is rated 80 Plus GOLD, which means it offers a power efficiency of up to 87% at full load. This is more than enough more for most PCs, even with power-hungry components installed.

However having said that, if you do overclock or have a beefy system that’s used for heavy work loads, I would recommend a larger power supply of 1000W or higher.
