Cooler Master V SFX GOLD 850 ATX 3.0 Power Supply Review

Ever since the SFX form factor was introduced over 25 years ago, I’ve always been fascinated with its compact size. And over the years, this form factor has become so popular, we’re now seeing it everyday from mini-PCs to custom built mods using mini-ITX motherboards.

Today, we’ll be taking a look at the Cooler Master V SFX GOLD 850 ATX 3.0 Power Supply. It’s a compact modular power supply that’s certified 80 Plus Gold and supports ATX 3.0 standards.

It uses high-quality Japanese capacitors for improved efficiency and reduced ripple noise. It features a powerful +12V single rail at 70.8A giving you a maximum power output of up to 850W.

The power supply comes in a compact SFX form factor, measuring just 100 x 125 x 63.5mm. It also includes a SFX-to-ATX bracket, allowing easy installtion on to any mini-ITX PC, all the way up to a full-size E-ATX system.

It comes with a 90-degree 16-pin (12VHPWR) PCIe 5.0 connector that allows for higher electrical durability, lower temperatures, and improved safety.

The package also includes additional flat modular cables … 4 x PCIE power, 2 x SATA power, and 1 x Molex. And for easy cable management, you get load of cable ties and a velcro strap allowing you to tidy up those messing looking cables.

You also get a massive 10-year warranty, which is unbelieveable.

I would like to thank Cooler Master for providing these review samples! Let us see what Cooler Master has to say about themselves on their website:

Building a PC is a highly personalized journey. We know that components are carefully chosen based on price, functionality, and aesthetic preference. Your personality is embedded in each of those choices, transcending from hardware to an immersive, custom-built experience. From custom PCs to all-out gaming rooms, we encourage every decision to reflect who you are.

Our components represent so many different personalities because PC enthusiasts don’t fit into just one mold. It doesn’t matter if you’re a student on a tight budget, a graphic designer that’s brand new to building, or a veteran modder of high-end gaming PCs; we offer components to inspire creative freedom in everyone. We believe that personal preference and individual expression leads to innovation.


The simple desire to make something better is exactly why Cooler Master is the standard in thermal innovation today. The aspiration to provide better cooling was a matter of personal preference, inspired by the freedom and enjoyment in building and creating something new. Now, our strategic partners like NVIDIA and AMD, our loyal community of gamers and PC enthusiasts, all rely on Cooler Master to strive for thermal excellence. That’s the result of simply wanting improved functionality and wanting to tailor something to fit our personal preference. That’s how innovation starts.

The PC community is never short on feedback and strong opinions—we love that. Hearing your thoughts and ideas give us the opportunity to be a part of your building journey, it helps us perfect the DIY experience, and it encourages us to adapt our product development process. After all, it is the community of builders, creators, and gamers who are an integral part of Cooler Master, helping bring our ideas to life. Together, we have been able to heighten the standards of how PCs are configured, transform the way they look and feel, and surpass the technological expectations of today. That’s where our passion stems from and that’s what it means to truly Make It Yours

This is one of the first ATX3.0 SFX power supplies we tested in our labs, so it will be interesting to see how well it will handle today’s power-hungry components.

To test the power supply, we’ll be using our usual test rig which is comprised of an Intel Core i9-14900K processor, which has a massive Turbo Boost TDP of 253W+ at full load. We’ll also be using an Asus Z790-E motherboard, 32GB of DDR5-7200 ram, a Lexar NM800 2TB SSD, and a GeForce RTX 4080 Super (with the 16-pin PCIE 5.0 power connector). For cooling, we’ll using a Thermaltake ToughLiquid 360 Ultra AIO cooler mounted with 3 x SWAFAN 12 EX ARGB cooling fans.

OK, let’s jump straight in and start by taking a look at the specifications in our next page. You can buy the Cooler Master V SFX GOLD 850 ATX 3.0 Power Supply or around USD $149 from Amazon – https://amzn.to/4bM9EPL
