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

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.

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.

Using this in a custom diy epgu setup, cables are braided and high quality.

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.

HWBusters.com recommended, preforms well, and silent at low and medium loads. Corsair made a very good psu for those looking for a silent build. It has short cables meant for small cases, without cable extensions this is useless for a normal sized tower. So don't make that mistake. Highly recommended.

First, I can't get over how small this thing is! I have it powering a build with a 7800X3d and a RX 9070 XT and it's been running rock solid and super quiet. Yes, it is pricey but you are without a doubt getting what you pay for.

I did not get to use this power supply. It does appear to be very well built, however the cables (all of them) are far too short to reach any of the motherboard connectors. It appears this power supply is meant to work in a mini tower case. My full size case was much too large for this unit to operate.

Excellent power supply. Clean and simple design fits well in any set up.

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.

Great PSU. Comes with braided cords that are super flexible. It is quiet so far.

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