The S12II Series SS-620GB 620W 80 Plus Bronze Power Supply from Sea Sonic Electronics is designed for basic desktop computers that require low noise and simple installation. It has a 80 Plus Bronze rating, ensuring up to 87% efficiency and power savings. The 120mm fluid dynamic bearing (FDB) fan utilizes Smart & Silent Fan Control for a balance between silence and cooling, and is built to last longer than traditional sleeve bearing fans. In addition, the unit uses high-quality 105°C Japanese aluminum electrolytic capacitors, ensuring stable operation under extreme conditions and extended life. Included are all the cables you would need for a standard system build; however, this power supply unit is not modular so you'll have to organize and hide any unused cables.

    S12II Series SS-620GB 620W 80 Plus Bronze Power Supply is rated 4.9 out of 5 by 9.
    Rated 5 out of 5 by from Solid PS, Even With Everything OverClocked I have a few PS already, but they were all to big to fit inside a Bitfenix Prodigy M case (which I also bought from bh photo video) and still house a big graphics card. This one replaced them nicely, I have all the power cabling I need and more, but the rest is easily tucked away out of sight. Component's I've got it powering now Asus Maximus IV Gene Z Gen3 Mobo with boosted power settings i7 2600k OC to 4.6 Ghz GTX 560 maxed power boost in gputweak h100i 5400 HDD SSD Pretty Maxed out USB headers CPU is still a beast. Not sure of the power draw but I'm confident the PS can handle my upgrade to a 1080 water cooled.

    Rated 5 out of 5 by from Runs perfect and quiet All the needed cables and easy to place in a mini tower. Very happy to have invested $50. on this power supply. 5 years warranty in the box.

    Rated 5 out of 5 by from Simple, quality power supply. This product is simple quality. Like the cheapo power supplies out there it is not modular. All the cables come out in a bunch from the back and can't be removed or swapped out. Not the best for cable management inside your PC, but it gets the job done, and I wouldn't expect a quality modular PS for this price. And it gets it done well. Unlike the cheapo type power supplies, this one has top-notch components that are unlikely to fail and either stop working or break other components with an erratic power surge. It looks pretty nice too.

    Rated 4 out of 5 by from Fantastic product, but consider a modular PSU! Works great, the only thing I didn't like is simply the fact that it isn't modular, so the cables are bundled a bit tight and can be tricky to work with. If I had known that beforehand, I would have probably gone with a modular power supply. However, I still like this product and it was a great price.

    Rated 5 out of 5 by from Trustworthy Brand - Excellent Power Supply Needed a new power supply for my computer since my old one was becoming obsolete and saw this one for a good price. SeaSonic has always been a good brand so I decided to give this a try. Everything's working perfectly fine and there are no issues at all for me!
