Corsair CP-9020186-UK SF750 80 Plus Platinum Certified Power Supply Unit, SF Series, 750 W, Fully Modular - Black (UK)

Product Information

This is the first desktop PSU with fan failure protection I have come across. In other words, if the fan has a problem or the PSU doesn't detect it, which would happen if it isn't connected, the SPX-750 won't start.

I did not have any issues with temperatures before but now I am worried about the PSU, as the summer is approaching and the ambient temperature rises. We are happy to see Corsair have adopted all Japanese capacitors in both primary and secondary stages to offer long term reliability and stable operation under heavy load conditions. The primary bulk capacitor is by Japanese manufacturer Nippon Chemi Con and is rated 105c. OVP (Over Voltage) | UVP (Under Voltage) | SCP (Short Circuit) | OTP (Over Temp) | OPP (Over Power) Corsair are using Great Wall as the partner for this particular power supply design. The layout, construction and overall design is very similar to the SF600 model in the range which we had a look at before. All of the electrolytic capacitors inside are Japanese made, which is good to see – especially as Corsair claim this in their literature. The primary bulk capacitor is made by Nippon Chemi Con rated for 470uF, 420C and 105C.

Most of my gaming is 1440p and I limit the frame rate to 144. I don't see the point in going over that when my monitor is 144Hz. The only SFX unit that matches—actually surpasses—the SF750's overall performance is the SF600 Platinum. Although with 150 W less power output, it achieving better performance in some areas isn't surprising, like load regulation on the minor rails and ripple suppression. However, while it trumps its smaller sibling in power density, the SF750 also has the better cable configuration since it is equipped with twice the EPS, PCIe, and SATA connectors.

KitGuru says: If you are building a high end gaming system inside the SFX platform then this should be right at the top of your list. Peripherals: GK61 (Optical Gateron Red) with Mistel White/Orange keycaps, Logitech G102 (Purple), BitWit Ensemble Grey Deskpad. SFX power supplies always have to make sacrifices in regards to fan noise, and thankfully Corsair have taken some clever steps forward to alleviate this potential headache. They have adopted a larger 90mm rifle (normally 80mm) bearing fan inside this supply, and thanks to Corsair's Zero RPM system, it does not spin at all under lower or even normal load situations.The Corsair SF750 is an SFX power supply – and not one of the many extended units we have seen in recent years – its only 63mm x 125mm x 100 mm (HxLxW).
