INTRODUCTION:
I've read the other reviews, I didn't experience any of the issues these other customers are talking about. My unit is perfect. I don't know if that's fluke luck or if these reviewers are blowing smoke. Whatever the case...
WORKSTATION SPECS & VOLTAGE:
I have a 5950x and an RTX 3090 running primarily as a 3D V-Ray workstation inside a small, M-ITX form factor case. That requires some serious power, and my 800W SFX-L PSU just didn't cut it without having to limit the draw to both my CPU and GPU. The SX1000? No such trouble. Didn't have to undervolt anything. Everything "just works." My workstation can use up to 804W draw from the wall at full load, and the PSU is completely unaffected.
NOISE:
This PSU is incredibly quiet. I'd never noticed a PSU in my day to day, but the reviews here had me pay attention to it. I run at full load often, because I'm rendering in real-time daily. At night, I'm rendering scenes. After two weeks 24/7 consistent usage, I have had no issues whatsoever. The only noise I've noticed in my machine has been my GPU fan. The PSU is near silent.
I'm going to double down on this. I record music on the Macbook in my office, I was surprised when my studio mic (Shure SM7B) picked up more sound from my brand new 16" Macbook Pro's fans than it did from my rendering machine.
HEAT:
My unit does not generate a significant or noticeable amount of heat, either. It's perfectly normal and what I've come to expect from Seasonic. My experience with Seasonic has been mostly positive, as I still use a Titanium Seasonic 860W ATX modular PSU on another workstation in my office going on 8 years with no issues.
CABLES:
My cables weren't stiff at all. They were quite flexible and bent exactly as needed in a small, small form factor PC. They weren't luxury braided cables but for how premium and impressive this little PSU is, I didn’t have a problem. However, I’d implore Seasonic to make official braided cables I could use with this PSU. I’d pay a premium for them, even.
IN SUMMARY:
In my personal experience I can with full confidence recommend this product. In fact I'd do more than that: it's an impressive technical achievement to stuff this much power into such a small package. It's the cream of the crop for SFF PCs.
I'll update in six months and let y'all know how it's going, and soon I'll upload pictures of my build (still perfecting cable management).
