You only need to look it up on Google for reviews to tell: this PSU is amazing.
I've been building PCs for well over 10 years, and have always found funny how some Builders cram the highest powered PSU their budget allows into their PC. That's not how it works. You need to know approximately what's the peak power of the PC you're building. Reason? Efficiency. Efficiency suffers the most when a PC is pulling a small amount of power (eg: idle, web surfing, music, youtoubing, office, etc). The lower the percentage of load you're pulling from the PSU from it's total, the less efficient it is, the more money you're not saving on the electricity bill. That's why office PC usually have a 250W-300W PSU.
Secondly: don't bother with 80Plus Platinum/Titanium PSUs just yet. It's 2% and 4% more efficient than Gold at 50% load, but usually come with a hefty price premium over Gold certified PSUs. It would take a lot more years to get the Return on the extra investment, than what you're probablly going to keep the PSU.
With that off the table, let's talk about the PSU. This device is powering an Intel Core i5 based system, overclocked to 4.0GHz, 16GB of RAM, one SSD and one HDD, 5 fans and a GTX760. It has power to spare, while being EXTREMELY quite, and exhaust air is relatively cool compared to older PSUs when gaming. The cables are flat, which are a godsend for cable management within the case, and a pouch for those extra modular cables you won;t be needing. Comes with a rather large sticker.
Why Seasonic and not higher named (Seasonic is not small by all means) brands like Corsair, Antec eVGA or similar? We can't generalize, but keep in mind that SeaSonic is one of the OEMs for many of the PSUs from those brands. They rebadge, relabel and rename the units, and sell them usually more expensive, adding little to no value. Save yourself a couple of bucks here.
Great power supply! Well reviewed and the 80 plus rating means it will waste less electricity than other units -- most of the power taken from the wall will wind up as clean energy for your computer and not be wasted as byproducts like heat.
Speaking of heat, this is a very quiet power supply! I can't even hear it from six feet (two meters) away.
The power is very clean even under stressful conditions. How do I know? It's science!
Seasonic is a well known OEM for other manufacturers. What is an OEM? Google it! Okay: it's an original equipment manufacturer. Which means it makes the products more recognizeable marketers put their labels on and sell to you as their own. Antec, Corsair and XFX all sell Seasonic power supplies that they label with their own company monikers. Not that there is anything wrong with that! Seriously it is a common practice, I am just letting you know that Seasonic is a well known and well respected power supply manufacturer.
I love this power supply so much. Very quiet and the wiring is of very nice quality. I will certainly buy another SeaSonic PSU in the future.
Details in case you are curious if you can run your computer with this 550 Watt. CPU: Intel i5-4670k running at 4ghz Ram: 32gb (4x8gb) G.Skill DDR-1600 Storage: 4 tradition spindle hard drives including a Raptor and one Samsung SSD. Graphics: 1 GTX 770 Motherboard: Asrock z87 extreme4 CPU cooler: Corsair h100i Case: 5x 120mm fans
I did a lot of research and reading about reliable power supplies when deciding which one to buy for my new custom-built desktop PC. Seasonic power supplies were always at the top of the list of reliability and good quality. I bought this power supply because it is built for the new Intel Haswell processors and it has an 80 PLUS GOLD rating. My new desktop has been running for a month now and there have been no problems at all from this power supply. It is never loud when on, even when running games at high graphics (the video card fans are much louder and audible than this fan). No major issues as of yet, hopefully it will keep my computer running for many years to come.
The only thing I had trouble with was the location of the SATA plugs on the back of the unit. In my case, the power supply is at the bottom, with the fan facing down. This allows the fan to draw cool air from the bottom vent opening and the fan pushes the hot air out the back of the case. The SATA plugs in this configuration are set low, closer to the bottom of the case. Since my case allows for an additional fan to be placed on the bottom of the case, the location of the SATA cables prevented me from using a 140mm fan. I had to settle for a 120mm fan instead. This may not be a problem for your particular case, but just be aware that when the power supply is facing down (fan facing down), the SATA plugs are closer to the bottom. Other power supplies have their SATA plugs closer to the center or near the top of the back panel (further away from the bottom of the case).
