Seasonic Focus SGX-750 | 750W | 80+ Gold | Full-Modular | SFX Form Factor| Low Noise | Premium Japanese Capacitor | 10 Year Warranty | Nvidia RTX 30/40 Super & AMD GPU Compatible (Ref. SSR-750SGX)

I'm using this 650w Seasonice SFX for a SFF living room PC build in a Silverstone Sugo 16 case. For initial testing, I hooked this up to my main PC (running a 3080 ti), and overclocked the gpu so that total system power draw was 630w. I ran it for 20 minutes with no issue and I eventually got bored. I was satisfied it could handle anything I would use in the SFF PC (would be much lower power draw). The fan made noise, but at 630w, it was impossible to hear over the rest of the cpu and gpu fans anyway. At reasonable power levels, the fan is essentially inaudible. I've switched it over and have been gaming on it for several weeks at around 300w or so. Works perfectly, and I picked it up on a good sale. Overall: quiet, reliable, lots of connectors. Would purchase again.

Alright, so I caved and bought the Seasonic Focus SPX-750. Why, you ask? Because if I’ve learned anything from watching Linus Tech Tips, it’s that Seasonic makes PSUs so good that even Linus might marry one if he could. Seriously, the guy talks about Seasonic like they invented electricity or something. And you know what? Maybe he’s onto something. This little SPX-750 power supply is like the Swiss Army knife of PSUs—compact, powerful, and so reliable it could probably babysit my kids. It’s got all the premium features Linus keeps raving about: fully modular cables (because who needs extra cable clutter), 80+ Gold efficiency (because we care about saving the planet and our power bills), and the legendary build quality that makes me feel like I’m holding a sacred tech relic. But let’s be honest—did I really need to spend extra on a Seasonic just because Linus practically sings their praises in every video? Maybe not. But did it feel good to hear that angelic choir of efficiency when I plugged it in? Oh, absolutely. So, if you’re tired of hearing Linus praise Seasonic like they’re the best thing since sliced bread… you might as well give in and buy one. Turns out, he’s right (this time). Five stars for a PSU that lives up to all the hype and makes me feel like I’m part of an elite Seasonic fan club. And hey, if it’s good enough for Linus to serenade, it’s probably good enough for your build.

750-watts PSU is more than enough as a replacement for 600-watts ATX PSU I've been using. It is really silent even in full load(maybe because power drawn isn't that much). I can hear little coil whine in high load and relay-clicking sound during booting/shutting down. But it doesn't bother me as they are quieter than chasis fan and CPU fan noise.

The Seasonic PSU is SFX and it is so small. This PSU was silent, no hitches or anything. The build seemed to great. It's an efficient 80+ gold psu with Japanese caps. Wish there were more SATA cables and ports but its understandable for the form factor. The cables did seem a bit short which is also understandable as this is usually meant for a SFF build in a small case. Plan was to use this for test bench and ultimately throw this into a NAS system.

I opened the box and it all seemed OK. Connected the essentials, motherboard power, graphics power, and it powered right up. I continued my build - and connected the RGB to a fan controller. Upon power up, sparks flew, melted cables, etc. What happened was a catastrophic failure due to having a cable in the box which did not belong to the Seasonic power supply. I counted them, and there were 3. Two were alike, one was not. I checked the back of the connectors to the PSU and the wires were not in the same order, on the same spots. Evidently there was a 3rd cable in the box that didn't come with it from the factory, and unfortunately for me, I chose poorly. I lost a case, a motherboard, and my argb controller in the process.
