    Silent and powerful power supply, worked right away, I use it to drive an Intel i3 3.6 GH and an nVidia GTX 970 no problem so far. Only con: it's not modular

    I've had this power supply for a month now and it is still going strong. No complaints for me, fit in my case just fine and powers my graphics card as well.

    Great power supply for the money would definitely recommend it for lower to mid level gamers or if you just need to replace the old power supply in your PC

    Well, I've only had it in a couple of months, but it's working great! I love the 5 year warranty that came with it. My previous supply was an Antec one that had a 2 year warranty. It went out in 18 months, was replaced, then went out 18 months later. So I got 3 years and a lot of headaches from Antec. I was ready to try a new brand. The low price, long warranty, good reviews, and many ports is why I chose to try this one. Let's hope the gamble pays off. I'll come back and edit this review if it doesn't!

    If you want a good power supply then this one is working really well for me so far. Its a little harder to manage the wires since this isnt a modular PSU but it is a very reasonable price for the power you get. Just put in a little effort with cable management and this will be a perfectly fine PSU.

    This power supply is your basic power supply; it gets the job done, plus a toggle power switch--which isn't on every power supply I've ever owned, but now I don't want to not have it. Bells and whistles aren't terribly abundant options, considering this is a component piece, but they do have a couple details I enjoy, like all black cables. The cables are also flat, which, depending on your case, could go a long way toward packing a clean case--not everyone cares about these things, but I do. A heads-up: if you're working on an older rig, with that standard 4-pin input to the motherboard, they're making 8-pin hook-ups, now and this power supply has both covered, but you have to snap the piece apart to use just the 4-pin. Most people who build computers, that I know, read reviews, but skip directions. So before you take it back, take a solid look at the connection, you'll see the seam, snap it, it's meant to do that.

    My PS failed and I needed to replace it. This unit did that! The Thermaltake engineers have figured out how to shrink the magical power gnomes to fit into the very small case. They work very quietly, but if you listen closely you can hear them singing a catchy tune. I can't quite make it out maybe somebody else can tell me the song.

    Works great. No problems after a three month of use. Good built quality. I was looking for a good power supply for the price. This supply gets good reviews. It is very well made with flat ribbon cables for routing cables easy, long cable for no compromises if you have full tower or want to rout cables behind motherboard tray. It was very easy to install.

    I bought this to power my new graphics card on my computer. Works great and has plenty of power to run all of my components. The cables are flat, instead of round bundles like typical power supplies. The only thing I wish this had was a modular design to remove unused cables.

    My old power supply crashed and this was the closest thing that Best Buy had to what I was replacing. It's got enough power and cable do so an SLI hookup, but I really just needed enough for my GTX 970 gfx card. It's not very pretty and it's not a modular unit, but it does the trick .

    I was looking for a quality power supply to get my desktop up and running again. This was just what the doctor ordered. Decent price and about 10 minutes of time to swap the old unit out and I was rolling again. Would recommend!

    Works flawlessly with my 6-core AMD FX Processor and AMD R9 380 4GB Graphics card. It has two PCI 6+2 connectors which means you can easily upgrade to other graphics cards later on. However i can't say how well it works with Intel CPUs and Nvidia graphics cards.......
