VERY Dependable, Powerful, Cool Running Power Supply

VERY dependable, cool running power supply.  Have it powering an iCharger 308 1300 Watt battery charger with no problems whatsoever.  I have tried multiple brands of power supplies, and nothing has come CLOSE to the power, dependability, efficiency, and ease of use as this thing.  If you're on the fence about buying it.. just buy it.  Dependability is worth something.  I don't write a lot of reviews, but this unit is worth taking the time.

On full load I'm drawing 787 watts (includes my 2 LCD's and my router) per my UPS and I idle at 380 watts.  Q6600 overclocked stable at 3495mhz so far, QuadFire 3870's (x2 3870x2's ASUS) overclocked, 4 hard drive raid 0 + 1, 500gb sata II drive, 2 DVD burners, and a floppy all in the Antec 1200 case.  This PSU is very quiet, and so far so good it can handle everything I'm throwing at it.  Plenty cord length for my tower of a case to hide the cables behind the mother board too.

As an update, having used this power supply for 8 years now and it's been on 99% of that time, it's still kicking, never had 1 issue, and I'm a big gamer & overclocker.

This is a very high quality built power supply, and saves money over cheaper ones.  I am reaping back the larger initial investment, in lower power usage over the 12 year warrantied life expectancy.  As high of quality as the components look, it will probably last as long as whatever equipment can be ran by 600 watts.  It has had no problems pushing a 3370K i7, two case fans, a processor fan, four spindle hard drives, and a 970 GTX SSC wired with both the pigtail harnesses.  Pay close attention to the instructions, which show to run both pigtails to the video card, to provide more copper for the power flow.

This is a really nice power supply. Heavy-duty aluminum case. Mounting tabs on either end with three bolt holes each. I'm using this to drive about 6 meters of 5050 (60LED/meter) strip for a 40" sign backlight.

I bought two of these and am happy with both units. Both of my units run very quietly with no problems during the two months they have been running.
The last Rosewill I bought has been running for six years and still going strong.
One of these power supplies is hooked to a i5 Skylake with 16 gigs of ram and two hard drives.
The total power draw including a 24 inch monitor is only 47 watts, granted this is with onboard graphics but still very impressive.

arrived before the estimated delivery date, very nice power supply, i'm using it with a asus h61m-k pair with a core i5 3470 ,8gigs of ddr3 samsung memory at 1600 mhz, a couple of 500 gb seagate  hard drives and a amd r9 290, everything work flawesly

Delivers consistent power from each port.
Very reliable imo!

I'm very pleased with this power supply.  It is a replacement for a Corsair power supply that died in less than a year.  The fully modular design makes cable management and routing a breeze.  Lots of bang for the buck here.

Excellent power supplies. I have two of these power my workstation. Have had these for several months and power is consistent and reliable. Hands down has my Antec 1000 80plus beat!

LOVE this power supply. Super quiet, and fully isolated. I had to go with this particular model because I really needed that single AC output it offers. But I would buy it again regardless if I needed that feature or not. Built like a tank too. Very satisfied.

This is an excellent power supply useful for a variety of devices. I use mine to power an Arduino (an embedded processor board), and to power various DIY projects.

Just remember this delivers a range of voltage up to 12V. 12V can fry devices not made to withstand it. Therefore it's a really good idea to "turn it down" to 3V when you have unplugged it in case you or someone else picks it up and plugs it into a sensitive low-power device like a GPS. This warning is not a device fault, of course, but a feature which you could accidentally misuse.

It does everything it claims - and does it well - so 5 stars. I do wish it also supplied 3.3V (not just 3V) as 3.3V is a power requirement for some electronics. (But I knew this did not provide that voltage when I ordered it, no fault there. For low and specific power needs like that, I really just need a bench power supply).

I've been building my own PC's for over 10 years now, and there are two things I've learned not to skimp on:  cases and power supplies.  That means replacing the el cheapo power supplies that come with most cases.
This is even more critical with today's multi-core processors, large amounts of memory, and large hard drives, and DVD drives.  This product gives lots of good, clean power, has a single rail design with 35A on the main (12V) rail.  There are also more plugs than you'll probably ever need
(I just tucked the unused ones into a empty drive bay).

I just bought a second one of these puppies for another one of my boxes - same comments apply

Originally bought a different supply (80+Gold) for this build. while I was waiting for the other one (won't mention brand but part starts with SDGR). The power was drawing 23 to 50 watts during the build. Received the other brand plugged it in and the power jumped to 47-52 watts idle and up to over 100 watts under load at times. Not to mention the fan never stops and is very load if your looking for a quit supply that not going to drive up your electric bill.
Now about this supply Supper quick with no fan running unless required. Even at the highest loads and intentionally blocking the vent it did turn on at a few RPM's and still silent!
Now for the next even better part is the power usage dropped way down comparable to the first full size supply. Idles around 25 watts and maxis out under full load of about 65 watts under the highest load I could put on it.
Being a big Seasonic fan even before most people ever heard of them! As usual another great little supply from a great company.
Just for some simple match I did on the other junk supply it would cost 25~45$ per year in wasted energy not to mention the heat. And that is also it is on 24/7 as most computers are these days. This was also a priority low power build. Using it in a higher demand system could run that cost a lot more. SO save your 30$ up front and give it tot he electric company and heat your or cool your house worth the other wasteful supply. Besides the other one weights half the weight and most supplies I see like that have a very short life plus little protection from frying other components !

I like this power supply mainly because it stays so cool when in use and has the adjustable voltage for use with many devices.

This PSU is pretty darn amazing. If you're looking for a 550w Power Supply, I highly recommend this.
It's virtually silent, has sleeved cables, and the quality is extremely high.
There are no negatives I can think of.

I haven't owned this power supply long enough to definitively review it, but it has been rock solid for 24/7 operation in the south Arizona heat. There's not much to say that the product information doesnt. I have the rated continuous power i need, the connectors (and then some!) i need, and the industry standard for clean and protected power supply.

Review may change if a failure occurs

Good value for the money! I am very happy with this power supply and would recommend it to others!
