I purchased this power supply in an attempt to reduce the jet-engine noise level on my system.

A bit of back story: My previous 550 Watt power supply, manufactured by Ultra, was a nightmare. The first one had an unacceptable/poorly manufactured fan inside of it. I argued with Ultra for days about a replacement. The whole process was a nightmare. I finally received a replacement. And though it was functioning normally, it was VERY loud. The fan would operate at full speed. The only thing my computer needed was a pair of wings, and it might have passed for a jet. It also generated an incredible amount of heat. Enough was enough...

I searched for some reviews on silent power supplies, and SeaSonic appeared on every search. Upon further searching, I found that there are some power supplies with "80 Plus" certification. Meaning that you'll get more efficiency out of your power supply. More efficiency = Less heat = Less fan noise. There are several levels of 80 Plus certification, each with increasing levels of efficiency: 80 Plus, 80 Plus Bronze, 80 Plus Silver, 80 Plus Gold, and 80 Plus Platinum.

I ultimately decided to purchase this SeaSonic 750W X750 Gold Power Supply. Excellent decision.

The packaging alone made me feel like I was going to be impressed. The embossed black and gold box made it appear sleek and elite. Upon opening, I found the power supply inside of a black velvet-like bag with gold writing on it. Cooool.

Aside from the packaging, the product itself was very easy to install in my extremely quiet Cooler Master HAF X case. This particular case positions the power supply on the bottom, rather than the top.

Purchased the SeaSonic X750 Gold in Nov/2010, for a new computer build. It was delivered within about 10 working days in excellent condition. I have used the computer every day for two months without any problems with the power supply. It is very quiet. Even when the cooling fan comes on (rarely), I cannot hear it. The power supply probably exceeds the requirements for my system but it allows for future additions. I considered less expensive makes (Corsair, Asus, other good quality) but decided to spend a little extra because of the reviews. Manual is good and comes with many more power cords than needed for a new build. All the parts seem to be excellent quality. Would purchase - from Amazon - again.

I got this one to replace the Cooler master one I had . This is a Rock and extremely quiet. I did have to figure out the right connectors to use. This one is overkill, but that is what I like. Do it right once.

The Seasonic 750w power supply was purchased as a warehouse deal. It arrived with all the parts in good condition. It became a part of a new built computer. The new build computer is using a Intel I5 Skylake CPU on a Asus Z170 mobo.

No issues, excellent package overall with ample cordage and convenient organization for unused components (i.e. cables).

Update: 1 year

This PSU has continued to deliver great performance and pay for itself over again with the extra cables provided. I've dealt with several power supplies in building various systems (Corsair, CoolerMaster, etc.), but I will say without hesitation that I would now buy a SeaSonic every time.

This is a fantastic power supply backed by an extremely solid company. I love the design and the hybrid feature. Fully modular was an awesome choice as well when cable management was taken in to consideration.

It came with an assortment of goodies including cable bags made of fine material, twist ties, and extra screws.

This power supply is currently powering an Intel i5 4690k, an MSI Gtx 970 Golden Edition, 8GB of Corsair Vengeance Pro, 1 7200RPM Hard Drive, 3 140mm Case fans, multiple USB devices and a Corsair H100i liquid cooling system.

Being gold certified this power supply will help save on your electricity bill. It also comes with a 5 year warranty from the manufacturer. These things are built pretty solid especially considering it is a Tier 1 power supply on newegg.com so you can expect nothing but the best from this product and the company that sells it.

I really dug on the packaging for this unit, normally I wouldn't remark on it but...the inclusion of a velvet bag is a nice touch. It being fully modular at such a great price is quite awesome as well.

I'd like to note though that if you are using a large case such as the HAF X like I am, you will need to know that certain cables might require extensions (such as the 8pin CPU cord). Also worth noting is that the 24pin motherboard cord is unusual where it connects to the PSU, so if you are ever in need of a replacement it could be difficult.
