SF1000 (2024) Fully Modular SFX Low Noise 80 Plus Platinum Power Supply – ATX 3.1 Compliant, PCIe 5.1 Ready, Small Form Factor, Bracket Included – Black

I chose the CORSAIR SF1000 (2024) for my small form factor build, and it has been an outstanding purchase. The build quality is exactly what you’d expect from Corsair—excellent. It’s compact, incredibly well-built, fully modular, and operates very quietly, even under demanding workloads. Cable management is also much easier thanks to the incredibly flexible modular cables, which are some of the best included cables I’ve ever used. For compact cases like the A4-H2O, their flexibility makes routing and managing cables significantly easier, helping achieve a clean build without putting unnecessary stress on connectors or components. For a high-end system, especially in a small case where airflow and reliability are critical, I simply trust Corsair more than any other brand. The power supply is one of the few components where I never want to compromise, and knowing my hardware is powered by a unit with such a strong reputation gives me real peace of mind. When you’re investing in expensive components, that level of confidence is worth every penny. If you’re building in the A4-H2O or any other premium SFF case, this power supply is an easy recommendation. It combines exceptional build quality, whisper-quiet operation, excellent efficiency, outstanding flexible cables that are ideal for SFF builds, and the long-standing reliability Corsair is known for. It’s exactly the kind of PSU you can install once and trust for years to come.

This is great sfx psu, but the cables might be short if you are planning to use this in an atx (or non-sff) case.

The Corsair SF1000 (2024) SFX Power Supply shipped incredibly fast and showed up the next day with Prime, which is always a great start. Right out of the box, Corsair’s attention to detail is obvious - excellent packaging and a premium feel throughout. Installation was straightforward, especially with the included SFX-to-ATX bracket, and it fit my L300 case perfectly. Compatibility was spot-on for a compact build, though it’s still smart to double-check cable lengths depending on your setup. Speaking of cables, there are plenty included, they’re nicely sleeved, and they make cable management clean and efficient. Performance-wise, this PSU delivers serious power with rock-solid stability. The 80 Plus Platinum efficiency and 105°C-rated Japanese capacitors translate into excellent reliability, even under heavy loads. The low noise level is another big win - the 92mm PWM fan stays quiet while keeping everything cool. Cybernetics rating this as one of the best SFX PSUs of all time definitely shows here. That said, I’d recommend waiting for deals around the $180 mark with coupons - t’s an absolute no-brainer at that price. Overall, this is a top-tier SFX unit that nails power delivery, reliability, cable management, and ease of installation in a compact form factor.

I bought this item brand new, shipped and sold directly from Amazon, so I expected a factory-sealed product. Unfortunately, that wasn’t the case. The PSU I received was clearly used — it had the well-known LPN label on the box, which is usually a dead giveaway. On top of that, the box wasn’t shrink-wrapped, and the cables weren’t sealed in their original packaging. Everything was just loose inside, which isn’t what you expect when buying a “new” product. After looking through other reviews, it seems like this isn’t an isolated issue either, which is pretty disappointing for something advertised as brand new. That said, the PSU itself seems solid. It’s clearly a high-end unit — efficient, well-built, and easy to install, with great connectors. No complaints there. I just wish I actually received a new one like I paid for. At this point, I’m going to keep it because I don’t have the time or energy to deal with a return and wait for a replacement, but it’s definitely frustrating. I’d recommend buying from somewhere else if you want to be sure you’re getting a truly new unit.

I have it powering my 9800X3D and 4070ti Super combo. Probably couldve gone with a 850W, but for future proof upgrades, I went with the 1000W. It of course powers these components beautifully, the internal fan had never even turned on. It’s dead silent. I use it inside my Lian Li A3 case, and the cables are the perfect length! It helps with the organization and management of all that, especially if you have built inside an A3, you know the challenges lol, I love this psu, looks cool too.

Fit great in my mini itx build, it powers my 5070 ti oc and ryzen 7 9800X3D quietly and cable management was great, I love the modularity of the cables and they all click into place nice and tight. It's small but extremely powerful and lives up to the hype. 5/5

Built my first SFF gaming PC and the SF1000 was the gold standard so I had to get it. One thing to note (which surprised me) is that corsairs SFX PSUs don't have a native 12v-2x6 connection like other SFX PSU's. It uses dual 8 pin on the PSU side and 12v-2x6 on the GPU side. No difference in performance but something to consider in terms of cable tidiness. Overall happy with the PSU performance and noise levels.

Handles my ryzen 5 5500 and 9060 xt 16gb great, quality is good, cables aren't too stiff, good for itx build. Noise is excellent I don't think I've ever even noticed fans turning on, and for the price I got it at ($169) I have zero complaints. Not sure if it's worth full price for such a mid range build but for me it's perfect.

Excelente fonte. Está segurando uma RTX 5090 Astral OC e um Ryzen 9800X3D tranquilo.

La fuente es super silenciosa, solo cuidado los cables son muy cortos

No significant complaints except the cables can be slightly too short depending on which case you are using. They do list the lengths on their site so I would highly recommend checking it prior to ordering as getting other cables is quite costly.

Anteriomente tuve fuentes de la serie SF y nunca me decepcionaron, tener una version de 1000 watts es genial

Dead silent, cables are a bit tight in my Lian Li a3 but it works perfectly. Bought a Lian Li SFX power supply first, coil whine was unbearable. Save yourself a headache and just buy corsair.
