Review: Muy recomendable para ensambles pequeños, por el tipo de cable que tiene es muy fácil si orden y manejo. Pero solo la recomendaría si le encuentras en oferta como yo, ya que en su precio normal puedes comprar una de otra marca con más watts.
Review: I've had my last few rigs in the Lian Li 011 mini (OG version) so I need SFX PSUs. Prior to this I had the Cooler Master V850, which served me just fine for the last couple of years. However, recently I upgraded all my Corsair fans and AIO to the new LINK ones and the controller requires a PCIe power cable connection as SATA is insufficient for the power requirements. The CM V850 did not come with enough PCIe cables. Sure, I could have bought another cable but I'm actually glad I bought this Corsair PSU instead, it was definitely an upgrade over the V850. First of all, the included cables are braided and are very nice, that alone was worth it for me. In addition, the Corsair has 5 PCIe ports and includes 3 standard type 5 PCIe cables, 2 CPU cables, and a 600W cable for modern GPUs (this was a nice surprise for me when I opened the box, I didn't know it came with this PSU). That allowed me to get rid of the nVidia adapter I was using, which further cleaned up my case. All in all I'm very pleased with this PSU, its dead silent and the cables are amazing.

## Questions & Answers

**Q: Do Small (SFX) PSUs Have Different Cables to Regular (ATX) PSUs?**
A: Yes, they do. SFX PSUs come with significantly shorter cables. These units are built for very compact PC cases that don’t require the long cable runs typical of standard-sized PC cases.

**Q: Does the quality, design, or actual connections differ when compared to large ATX power supplies?**
A: No. They use the same types of cables. While you can technically power a full-size PC with a smaller SFX PSU, the practicalities can be troublesome. In mid-to-large PC cases, it might be impossible to stretch the short cables far enough.

**Q: What type of case should I use with a SFX PSU?**
A: SFX PSUs should only be used if you plan to build a PC in an SFF (Small Form Factor) case.
