Corsair VS400 Casing
The change of the Corsair VS400 is a lot more than its predecessor. From the first look at the box, the main color is black gold is very prominent, sturdy, containing full information of the product. Provides the most intuitive and useful view for users to view information about the product.
The VS400 is a PSU cable circular very beauty, resistant to cutting and breaking. In addition, the cable length is enough for the PSU to connect devices in the mid-range high-end ATX case as well as the current line.
Unlike the old VS450 predecessor, the VS400 has a full ripple when it’s a full-range A.PFC equipped PSU with theoretical voltage range from 88VAC to 264VAC. With the A.PFC, it does not interfere with the AC input and the PSU does not need a 110 / 220V line switch like some other popular products, which is very convenient for end users when the PSU is automatic. Transfer lines to fit the use. In addition, if a user uses an extra UPS, the UPS retention time will be longer if an A.PFC is available.

At this Entry Level line, Corsair has partnered with HEC instead of CWT OEM for their products. This led to the VS400 being a completely new product by HEC OEM. The first thing to notice is the 120mm 120mm, 12V, 0.33 A, 1500 RPM 120mm fan from Hong Hua, which provides good cooling capacity when it can move large volumes. The air is slower than the smaller diameter fans, leading to faster cooling and lower noise.
The windshield is covered by a molded plastic molded into the fan frame, which guides the air flow from the inside out, optimizing the cooling of components located in the corner of the PSU.
Interior of the VS400 with PCB is quite airy and clean. Cooling system is well designed with thick aluminum sheaths to heat the heat from the PSU components.
Similar to many other PSUs, the design of the convex aluminum radiator bulb is raised to allow for better air exposure for heat dissipation. With 2 separate aluminum radiators for the hottest operating components: PFC, PWM and secondary DC diode.
The main transformer is Corsair, which looks pretty big and it’s the ERL 39 – a transformer that only works on 600W PSUs, which is too much for the VS400.
The most obvious part is the A.PFC section, where the PSU is equipped with a mains filter of 270uF / 400V rated at 85 degrees Celsius, with a rated power of 400W (12V line occupies 384W). Equipped with a filter capacitor like this filter is very suitable for places where power voltage not stable.

To assess the specific power that the VS 400 represents, we put it in a configuration that exceeds the power of the following:
– ASRock Z170 Extreme 7+
– CPU Intel i5 6600K @ 4.2GHz
– Asus Strix RX480 running Crossfire
– Kingston Hyper X 2x4GB bus 2133MHZ
– Kingston V300 120GB SSD
Western Digital Green SSD 120GB
– Seagate Barracuda 1TB
The result is shocking when we let the system run at full power, Kill A Watt measured power consumption of up to 460W, exceeding the nominal power quite well. As a result, the Corsair VS400 can pull up two RX480 cards (components in the configuration are dragged full load by running AIDA 64).
However, over-powering this just proves that the VS400 is capable. We do not recommend that you use the VS400 with two RX480s. Remember that running at full power for maximum power for a long time will only cause components to fail fast, not to mention running overload as this case.
As for the measurement results in the operating mode does not load the voltage by 12.21V alarm clock and Kill A Watt 79.1W AC.
