Full-modular, V850 SFX Gold Perfect CM Power Supply

When it comes to power supplies, most people will focus on things like rated power, cable type and efficiency, which makes sense as they are extremely important. There is a fourth value that is rarely talked about because it has not changed much, the physical dimensions. A standard ATX power supply measures 150mm x 86mm with a depth of 150mm. depending on the manufacturer of the power supply, the depth measurement may change depending on the characteristics and power requirements.

For example, when power supplies started accepting modular cables, the power box would be made a little longer to accommodate the plugs. When the power capacity began to increase, the accepted standard grew from 150mm to 180mm and remained so for more than 10 years. For this reason, many people have forgotten that the physical size of their power supply is important when building a computer. In this review we will see a new Cooler Master Power Supply called V850 SFX Gold. The ” V ” series is very popular thanks to the modular design and affordable price, however this Cooler Master V850 Gold is different in that everything power has been packaged in an SFX form factor.Cooler Master V850 SFX Gold

The V SFX Gold is Cooler Master’s debut entry into SFX power units. After much demand, CM finally produced a power supply that was specifically made to meet the needs of mini-ITX system builders. This unit delivers performance in excess of 550, 650, 750 and 850 watt levels. It offers an 80 PLUS Gold efficiency rating, full modular wiring, a 92mm FDB fan, 16AWG high efficiency PCIe cables, 100% Japanese capacitors and a 10-year warranty. And with SFX-to-ATX support included, this unit is compatible with cases ranging from mini-ITX to E-ATX systems.
To put it in perspective, the SFX form factor measures at 100mm x 125mm x 63.5 mm, making it one of the smallest power supplies you can buy and which is based on a widely accepted standard. Here we have three elements to provide some scale. The first is the V850 SFX Gold depicted on the front. Behind it you will find an old Corsair 850W ATX with the entire depth of 180mm along with a single 2.5″ SSD to provide some reference.

Much has changed over the years. The Corsair power supply is not fully modular and has been built to support 4-way video card configurations. Due to the size of the Cooler Master V850 SFX power supply is built slightly differently. Photo: Cooler Master
