Corsair SF750 - Review

We see more and more users demand high power systems that take up little space. There are more and better solutions for mounting systems of small dimensions and a lot of power. For all these systems Corsair has developed the Corsair SF750 power supply with 750W power. This power supply is in SFX format and has been developed for mini-ITX systems.
Thanks to Corsair for lending us the Corsair SF750 for review.

Unboxing Corsair SF750

The Corsair SF750 power supply is a highly compact solution developed for very small systems. This is evidenced by the box for this PSU, smaller than other boxes. Naturally, the case has a dark body, as well as graphite gray and yellow edges.

We turn the box and on the back we find some technical data. The measurements, the efficiency curve and the fan curve of the same are shown. This source is 0dB, which means that until it reaches the 300W supply, the fan will not work.

Something quite curious is that the power supply comes with a cloth bag that protects it from bumps and damage. In addition, inside the box we find the user manual, cable ties, screws and a sticker with the Corsair logo. We also have the power cord that the power supply to the Schucko wall socket and an adapter to use this power supply in chassis with ATX space.

Regarding the cables, we find:
- 1 ATX cable (24 + 4 pin) [30 cm]
- 2 x ATX / EPS cables (4 + 4 pin) [40 cm]
- 2 cables x 2 PCIe connectors (6 + 2 pins) [40 + 10 cm]
- 1 cables x 3 Molex connectors [10 + 12 + 12 cm]
- 2 cables x 4 SATA connectors [10 + 10 + 10 + 10 cm]
Corsair SF750 design

This Corsair SF750 power supply features a very compact design. It is based on the SFX standard and has a total dimensions of 125x63x100mm, much smaller than any other font of the brand. Due to these small dimensions, it is an ideal power supply for mini-ITX systems.

To dissipate the heat generated by the components, a 92mm fan has been installed. The fan has rifle-type bearings, which makes it not particularly noisy. Note that the fan is inactive until it reaches 300W, which is the power that is considered to be idle.

We also see on one of the sides the voltages offered by this power supply and their power. Something interesting is that this source is monorail (mono, mono, monorail) for 12V voltage with an intensity of 62.5A for a maximum power of 750W.
Characteristics Corsair SF750

To offer clean and efficient cable management, this power supply is 100% modular. This allows the user to choose which cables to lay out, without having to have a soup of cables.

A very interesting element is that the power supply has the Corsair NR092L 92mm fan. The fan makes use of 0dB technology, which establishes an operating point. The fan is activated if the source reaches 300W of consumption or exceeds 50ºC with an ambient temperature of 25ºC.

On the internal construction of this power supply, we see that work has been done for the compact integration of all the elements. Making fonts so compact has its complication, since you cannot do without any conversion elements. We see the input transformer that reduces the voltage, as well as the filtering to convert the alternating into continuous. We can see in the central area the heatsink of the voltage transistors. The electrolytic capacitor Nippon Chemi-Con stands out above all for filtering and rectifying the alternating wave.

Conclusion
The Corsa SF750 power supply is characterized by being a compact power supply. It offers us an 80Plus Platinum certification, which guarantees us an efficiency of between 90-94%. This is important, since we are talking about a very compact source that would otherwise be very difficult to refrigerate.
We have verified the constructive quality of this power supply, something that very few can say. The finish is very clean, despite the compactness of the source and the welds are of very good quality. Also noteworthy is the fan that makes use of 0dB technology, not operating up to a certain power and / or temperature. The cables are modular, to allow efficient cable management and avoid having more cables connected than necessary.
- High quality components, clean and solid construction, and very good welds
- 80Plus Platium Efficiency, and Cybernetics ETA A and LAMBDA A-
- Fully modular wiring with meshing
- Compact design
- Very quiet even with the fan running
- Very fine tensions
- The cables can be short for ATX boxes, it is designed for mini ITX chassis or similar
