The Focus Gold, 80 Plus Gold 550W unit that I've purchased works just as well as I would expect. Even though of course, it's quite brand new for me and has only been with me for about 2 weeks of ownership, it's does exactly what I want from it.Thus far, It's quiet and has my new PC running smoothly, and it's hard to beat the 10 year warranty with it. I'm very happy to have made this purchase, and happy with Seasonic for this model. Full modularity makes cable management a decent breeze even with a relatively SFF (small form factor) build via a mini-ITX motherboard build. Makes me and my tiny PC both happy. To everyone reading this review, thank you very much, and take comfort in my assurance that with my personal experience with this PSU model, it's worked a charm so far. ~ Kevin ### ⭐⭐⭐⭐⭐ Easy to install and quiet *by J***S on May 7, 2019* Modular was pretty much a requirement for my ITX build. This PSU fit the bill and runs very quiet. It looks and feels well made and it comes in a small cloth bag (I don't know much about materials. Is it nylon? Dunno) that feels very professional. The cables come in a separate bag (in the same box) with a drawstring.I'm happy with my purchase. ### ⭐⭐⭐⭐⭐ Just worked, with no hassle *by J***N on March 19, 2019* My five-year-old and I built a gaming PC last weekend. Installing this PSU was so simple I let _him_ screw it into the case. I had to do a bit of Googling to figure out whether I wanted the fan facing up or down (I've never built a PC before), but after resolving that question, everything else was smooth sailing. Very happy with the hybrid fan control: one of my main aims was to build a VERY quiet gaming PC and I think I've achieved that. Even in modern games with all settings on ultra high (and a 4k@60Hz monitor to boot), I can't hear ANYTHING from the machine.I'd definitely recommend Seasonic; the PSU felt well-built and has served me well so far. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/45002889-seasonic-focus-plus-550-gold-ssr-550fx-550w-80-atx12v](https://www.desertcart.tn/products/45002889-seasonic-focus-plus-550-gold-ssr-550fx-550w-80-atx12v) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-21*
