Great psu that is gold certified!
This is a great power supply that is modular, gold certified and has a single 12v rail. It has plenty of modular plugs, though i wish it had more sata power plugs, that were strictly sata. I'm using this in a custom built server and have run out of sata ports, ill have to see if they sell just the sata modular plugs.
By Dwayne Gonzalez
Great product.
Pros:this product is powering my overclock phenom ll 965 (4ghz),hd7870 (tahiti le), fan controller (with 5 fans), card reader, dvd drive, 2 traditional hard drives and ssd perfectly! It seems to be better providing more stable voltage to my components than my other power supply. I'm actually able to knock a few volts off my cpu and the monitoring software for my gpu actually shows that the 12v energy staying over 12v, unlike my other psu (at least get an bronze psu when shopping). Monitoring software isn't 100% true, but something is better than nothing and my last psu wasn't split it.Cons:i just look inside the psu since i want to eye-judge what quality it is. I've seen a few places where white puss looks to be on two small areas of the psu. I was disappointed thinking,"how in the heck did this pass rosewill qc!" after being mad for a day and a half i decided to try it before rmaing it (i love rosewill too much without giving them a try). I tried it on my backup, backup system. It worked! Next, i tried it on my main system..... It worked with cpu & gpu under their respected stress test. I've seen multiple failed psu with white puss coming out. I don't know if this was because of an failure or the white puss/paste is just some way to have definite components stick to where they want them to stick. I just don't like it. It seems to not be affecting the product..... And that is all that matters, isn't it?I would recommended this psu to anyone that needs the recommended wattage. Product seems high quality and it comes with an 5 year warranty to give you that peace of mind. Hopefully when i get an fx-8320 this product powers it for 3 years till i retire it. One shouldn't skimp on the psu during a build. Trust me, i heard that when i first started building and kinda disregarded it. It held firm even though i didn't. Psus aren't the prettiest but it is need for the whole thing to work. An beautiful $5 million house on bad isn't worth anything. ;)

Excellent power supply
Everything was included in the box.All necessary power cables, with choice of connectors - molex and sata for storage drives.
By Argemira Da Rosa
As good as i could hope, but could have fit better.
The power supply works extremely well as far as i can tell after a few weeks. I got this to replace a second hand power supply that was fairly noisy, and had some cabling issues. The modular cables made getting things wired up very nice and easy, as well as not having to find a place to stuff unnecessary cables. The only issue that i have with it is that it was a very difficult fit in my case (dell xps 8000). I can't fault the power supply for that part as much, but once i got it seated, the upper two screws went in without a problem, whereas the bottom two didn't quite fit. I got the supply secured, but not as ideally as i would have hoped.
By Aubree Campbell
Just right for a dual power supply set-up.
So far, so good, ... No problems. Go to mfg web site to read all the specs, etc.Pro: quiet for it's power range.Con: price. It's not a fancy dancy power supply, but costs like one.
By Emy Louis
I've heard nothing but good things about the build quality of the rosewill legacy ...
I didn't necessarily need the gold certification, but since i was using this psu in a mini-itx build, i wanted as little heat as possible, hence the higher efficiency rating. I've heard nothing but good things about the build quality of the rosewill legacy line, and i've had no problems so far with the supply.
By Morris Lambert
Stable cool and quiet
I've been using rosewill psu's for over a decade and they've always been good to me. So when i recently built a m-itx pc i thought of rosewill again. Very well packaged and very cool and quiet operation.Specs:gigabyte z97n gaming 5 itxintel core i5 4960k (nooc)8gb gskill sniper2gb evga gtx 750ti sccorsair 250d mini itx (air cooled)

High quality product and excellent power
I'm very impressed and satisfied with the quality of this power supply! It's robust and i could also notice that it is manufactured with high quality components.It comes with long cables and is perfect for mounting in cases of any size. And finally, the energy it provides makes all the difference.For your computer's performance. If you employ a generic font, fair cease using it now! I highly recommend switching to a high quality source, especially being a rosewill. Your computer thanks!
