Not often I say this about a power supply, but this product is a standout. From the time you open the package you appreciate the attention to detail the manufacturer put into it.

I love that this is completely modular. I only need to connect the cables I need.

Also the cooling solution is very nice. In fact, in the default mode, the fan doesn't even spin up until the power supply hits moderate load. Even then it is almost silent.

It's a little longer than the typical power supply, so if you have a small form factor case (mini-ITX or mini-ATX) make sure to measure beforehand.

It's a premium product, and as such carries a premium price. It's hard to judge if it's worth the extra cost, but it's high power output and modularity should mean it'll have a fairly long usable lifetime.

I purchased this power supply unit back in Aug. 2011 from Newegg, for a gamer/work horse desktop. It was on pre-order for quite some time, at Newegg. I got it for $237, but with Newegg's shipping costs and sales tax, it winded up costing me more than what Amazon's price is, now. I had some issues with my ASUS Deluxe motherboard, but as soon as I resolve them, I'll post some pics of my new build with this Seasonic PSU. Here are some key features it has:

Seasonic Platinum-860 and Platinum-1000 PSU Key Features:

860/1000 watt continuous power output (up to 50°C)
80Plus Platinum certified super high efficiency
7-Year warranty

This has been my first purchase of a high end PSU (I've been building computers for years) and this just has a fantastic WOW factor, from the moment you get the box, it has quality written all over it. Extremely well presented, makes you feel you got value for money even before you install it. Install was a breeze (They even throw in a mini philips screwdriver, cable ties), however do bear in mind it is bigger than your average PSU. I love the modular cables, you plug only what you need, makes your case interior nice and managed. Very quiet operation, no issues.

For anyone out there hesitating to buy..... just buy it, it is a real quality product.

Check JonnyGuru, TechPowerUp, Guru3D and they all give this power supply a near-perfect rating. This is what drew me to this selection aside from Seasonic's stellar reputation for quality power supplies.

I got this to replace an aging TX950 not because it was bad, but because I'm a firm believer that you don't wait on a power supply to start flaking out on you before you replace it. This has kept all of my home-built systems running without fail until I deem them obsolete.

This Seasonic is my first fully-modular power supply. It now powers an Intel i7-3930K, an Asus P9X79 Pro, an Intel 520 Series 120GB SSD, an Intel X-25 M 80GB SSD, 2 Western Digital Black Edition 500 GB hard drives, 16GB Corsair Dominator RAM, a Corsair H80 CPU cooler, 2 GTX 680s in SLI, an LG DVD burner and 8 fans (2 on the radiator and 6 case fans) all within the confines of a Thermaltake Spedo case. I still have 2 PCIe 2x8-pin cables left over (and connections for both) as well as an SATA and a couple of 4-pin molex cables. I could theoretically connect two more 680s and another set of fans or power another strand of SATA-powered disks. I do not need 1000W for my system, but I know if I add more video cards or if new cards come out with an increased power requirement over the next 7 years (this is the warranty period through Seasonic!), this supply can do the job.

It was easy to install due to its modular design. There were absolutely no "gotchas" with this Seasonic unit. I removed the old power supply and then installed the Seasonic. Cable management is even made easy with the supplied zip ties and more than enough velcro ties. After it was installed I flipped the power on and made sure everything was running as expected.

Purchased this after lot of research, and when found on a deal. Excellent power supply. This is fully modular and supplied cables are plenty. Only negative is size, this is little longer than normal ATX hence can't fit in smaller size cases (like HTPC's which support ATX PSU's). Only reason to take out a star, but since I knew this before purchase keeping it 5...:-)

In talking to PC builders the number one component to cause problems is the power supply. Get a great, stable power supply and save yourself the hassle of an inferior product. This PS runs very cool and rarely does the fan even turn on (driving a hex core PC with a Asus Matrix Radeon 7970). I built my PC to be as fast as possible, and as quiet as possible which are often goals at odds with each other. This power supply is cool, quiet and efficient and does everything that I needed it to do. There is no better, the cost is high but worth it.
