Corsair SF600 80 Plus Gold SFX Power Supply Review

Final Thoughts

Pricing

The Corsair SF600 is available from Scan.co.uk for £99.98, which is obviously a bit more than most 600W units, but keep in mind that gold efficiency and the compact SFX form factor, as it’s one of the best performance and priced SFX PSUs on the market today.

Conclusion

Corsair has been pushing hard to make some truly spectacular power supplies recently and time and time again, they’ve delivered the goods. Their latest, the SF600, isn’t just good for an SFX PSU, it’s one of the best 600W units I’ve ever tested, and that’s something that shouldn’t be taken lightly. When you’re building a compact gaming system, size is important and an SFX PSU allows the use of a much slimmer form factor chassis. However, this used to mean a compromise on wattage, or efficiency and even then, you would be paying a price premium.

The SF600 delivers a huge amount of power for its size, more than enough to power any of the latest high-end graphics cards and a heavily overclocked CPU with relative ease. What’s impressive is that it manages to deliver all this power with exceptionally stable voltages, incredibly low ripple and even more so, it steps closer to the 80 Plus Platinum efficiency rating when it’s only rated as 80 Plus Gold; if that’s not great value for money, nothing is.

Overall, the build quality on this unit is as good as it gets. There’s not a single wire to be found on the interior of the unit, just nicely laid out PCBs that use a modular 3D design to save on space and help with airflow. The 92mm fan is excellent in terms of quality as even at higher RPM is was much quieter than we would have expected and even then, the optimised layout of the PSU means that it’s able to cool passively under lower load scenarios. The addition of fully modular all-black flat cables only helps to sweeten the deal.

“Picking the right power supply for an SFX build just got a whole lot easier. If you’re looking to build a compact gaming system or workstation, the SF600 is the best option on the market right now. Highly recommended!“

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
