Well I just installed it as a replacement and as a Tech guy I can tell you it is one of the quietest I've ever heard, or maybe I should say not heard. Quick and smooth installation with all the connections you might need. 2 PCIe connectors if you need them for a dual video set up. SO far I am more than happy with it, but of course only long term use will really tell on a power supply so I only gave it 4 stars. I tell you what though, I was very impressed with the packaging it came in. It was very snug in a nice box with bubble wrap tight on the PS. If you have seen as many Power supplies as I have you know that some are just tossed in the box, however it did not come with any "instructions" so if you don't know about power supplies, don't get it expecting even the simplest instruction.
I'll update this later if I have any problems with it.
One thing I do want to say negative is about the shipping..It took less time for it to get delivered to the town I live in then to be delivered by UPS. (one day shipping) According to the tracking info (ordered on my wifes account) it went out for delivery at 7:39 am and it was not delivered until about 7:15 that evening...Now thats almost 12 full hours..Is this a single driver making deliveries all those hours ? Doesn't this lead to a little fatigue ? Anyway 12 hours to deliver something it would have taken me 15 minutes to go pick up at the UPS facility is just not right for my money..If UPS is that busy on a Wednesday then maybe they should think of hiring more people on some routes ?

I bought this as an exact replacement for my old tower. The original was making a terrible sound and I came to find out that one of the fan blades broke off and was causing the racket. This power supply has been running 24/7 for the last year and I've no issues with it at all. You could spend a whole lot more money for a 650 Watt PS, but for what I need it for it's perfectly fine. Some other reviewers stated that it was noisy but I don't find that to be the case. It runs cool and quiet and has been purring along just fine.

Operates as advertised. Before I bought this power supply, I purchased another brand from Amazon - a Corsair, which was completely inoperable when I received it. I had to return it. No problem there. Amazon accepts the fact that they sell duds once in a while. I then bought this power supply and it is performing very well as we speak.

It has been running in the system for a while now with no problems. Built a simple system that needed a good processor and lots of RAM for database work and got this PS to power it. Checked over the voltages before using and numbers are in spec and hasn't given me any troubles.

For the price it's a good Power Supply. I haven't had any issues yet.

I found that some of the cables' lengths a bit short, and it seems a bit short on SATA power connectors and 6-pin PCI-Express connectors. Instead, it has an ample amount of the legacy 4-pin connectors. If you plan on using this in a machine with lots of SATA drives, video cards that need the 6-pin connectors, you may want to prepare to get some adapters. If you have an ATX case where the PSU is bottom-mounted or a BTX case where the drives aren't right next to the PSU you might want some extension cables.

I bought this as a replacement for a Dell that has a BTX case. I wouldn't use this in my main PC's build, as I'd need to invest in a lot of adapters and extension cables. This may or may not be a good choice for you depending on your setup.

Ive had mine for about 4 years, it worked great but just recently it hasn't been working, its been overheating, anyone know a way I can fix that, or should I just get a new one?
