The best PSU I've bought, for a few reasons.1. It is under $150 for 1000w, and being Seasonic, the name speaks for itself in the PC Building community.2. Comes with braided premium cables, unlike say a Corsair RM1200E that was near $300 that uses very rigid cables.3. As seen in my pictures, I built in a smaller case, the Lian Li Mini V2. I had absolutely zero issues "training" the cables to bend certain ways. This PSU is very cable management friendly. I used 3XPCIE cables in this build for a 3090, in a smaller case and had no issues tidying it up.4. Most importantly - for those who may upgrad

It really like that this power supply came with braided cables which made it easier for cable management. One of the small gripes I had with my old Seasonic Focus is that the cables were stiff but I really like that these are flexible. You can't go wrong with Seasonic, my old Seasonic is still working awesome with no issues, I had to replace it because I bought a new graphics card so I wanted to future proof my pc and not worry about meeting the minimum power requirements in the future. I have my old Seasonic for about 6 years and never had issues with it, I like that they are reliable and don
I built a new PC using all different parts. PC with a Ultra 9, Windows Pro, 128gb ram, ASUS motherboard with the works on it, I mean everything. I have a million things plugged into this PC. During the architecture part of my build this power supply was recommended by several of the AI systems I was using to evaluate the build. I've been on this new power house for about a month now without any problems. They included so many cables, more than you need and it should fit anything you have. They really thought this through. I would not hesitate to buy this again.
This power supply is the missing piece to complete my white build. The finish is premium and, unlike others, the cables are also completely white and of excellent quality, which makes cable management much easier and visually enhances the interior. Besides being aesthetically flawless, it is extremely quiet even under load. It is the perfect combination of style and reliable power.
I've been using Seasonic for a while now and I have never been disappointed with one of their products. Fairly priced for performance and they're just solidly made. Quiet performance even under full load it does have a zero rpm mode if turned on. Cables feel to be of good quality and the braid is worth it as well. Would recommend to any builder.
Amazing quality and cables are fancy out of the box it’s quiet super modular simple installation works with most gpu and motherboard
Doing its job! No problems from the 750w and 1000w!! I hear their cables can be swapped. Well do the test.
Nice look, heavy so you know it's got good components, great looking/flexible wires to make your rig look good and route easier and the modular attachments are just what you need to use only what's necessary. Have had a seasonic psu for years without a hickup, wanted another one for my upgrade. Extremely happy with this purchase.
