Still working just fine and runs very quiet.

The case fan that came with the box is louder than the power supply even though the case fan is pretty quiet too.

I would recommend this product to anyone needing a power supply.

I am an IT professional and have 4 desktops, 3 of them being in a lab environment, so when I fire up my lab, I have 3 PCs running which produces a lot of heat and uses a lot of electricity, so I decided to replace the 400W non-energy compliant power supplies with 4 of these. So far I have to give it 5 stars as I have not found any issues after about 2 months of use.

Runs quiet and cool and has enough connectors for my needs (4 SATA or less). The wires are shielded and thick, so they do look "cleaner" than if you have non-shielded wires, but I can see how they could be difficult to work with in a smaller case with little room. Also comes with tie wraps for the wires. I ran pre and post install power consumption tests using a P3 International Kill A Watt meter and the power consumption of these 430W power supplies was considerable less than with the previous power supplies (about 20-30% on average).

The power output (430W) works fine for me on all 4 computers although I run only on-board graphics. The specs of my two highest power consumption PC are:

-- MSI mobo with AMD 965 Black Edition 3.4 GHz Quad Core(no OC), 4x2GB (8GB) OCZ Platinum DDR-800 latency of 4-3-3-12, 2x120mm 3-speed fans, 2xWD 300GB Velociraptors in a RAID 0 and a dual layer SATA DVD drive with Lightscribe
-- ASUS mobo with Intel Q9650 3GHz Quad Core(no OC), 4x4GB (16GB) OCZ DDR2-800 latency 5-5-5-18, dual 300GB Velociraptors in RAID 0, 2x80mm fans, and a dual layer SATA DVD with Lightscribe.

Both systems run Win 7 64 Enterprise with power settings on High Performance (needed for my IT testing and VMs) and I use stock CPU fans that come with the respective processor.

Well packaged, good length on cables, very quiet, comes with zip ties for the unused cables and strapping things down. Hopefully will last more than my previous supply, but Corsair has good reliability ratings.

This is great!
No need to excess watts, this will hold up fine for most quad core PCs even with modern GPUs.
Do some research, don't overspend!

I bought this power supply 2 months ago, but I waited this long to write a review to see if the product was defective or not.
So far, it's running just fine! I would highly recommend this PSU as it doesn't cost much, has more than enough wattage to power a mid-hi-range graphics card such as the GTX 550 Ti (which uses 116Watts, for your information), and comes from a reputable company.

Specifications are as follows:
+3.3 Volts @ 20Amps = 66 Watts
+5 Volts @ 20Amps = 100 Watts
+12 Volts @ 28Amps = 336 Watts
-12 Volts @ 0.8Amps = 9.6 Watts
+5 Volts Standby @ 3Amps = 15 Watts
====================================
Total: 527 Watts (the 430Watts is what they advertise, but this can provide the extra ~100 Watts if needed)

A typical computer uses 150 to 200 Watts maximum (assuming that you don't have any other extra components other than the default included hardware). Even an overclocked system doesn't use more than 250 or 300 Watts maximum, so that leaves you with more than 140Watts for you to add a nice and powerful graphics card, extra harddrives, extra DVD drives, and other components without worrying about overloading the power supply. Unless you are going to use a super-high-power-consuming-uber-ultra-hi-def graphics card like the GTX 590, or you are going to SLI or Crossfire cards, this power supply will be more than enough for you. If you ARE planning on SLI(ing) or Crossfire(ing) cards, you must be crazy to think this PSU will do for you, because it WONT.

Hope this review helps. Also guys, when buying power supplies, remember to NOT buy multi-rail power supplies as they can be a pain in the neck. Even an overload on a single rail will shut down the whole PSU.

Size Name: 600 Watt Verified Purchase
When you first open it, you can tell the great quality when you see the shielding on the wires. I got this power supply because I was upgrading the video card on my HP Pavilion Elite HPE-480t. The installation was easy and it fit perfectly where the original power supply was located. It took me awhile to figure out I needed to detach the 8-pin connector into 2 4-pin connectors for my cpu fan. All and all, easy install, can't hear the psu fan at all, and is powering my AMD Radeon HD 6870 without issue. ***Rebate still works*** Saw that it expired on 12/31/11 but went to the website to try it out anyway. On their website, they are offering the $10 rebate till 01/31/12.

I bought the 600w Power Supply and after reading other reviews, I had concerns about fan noise and just wanted to report that it's quiet and appears to function properly. If you look at all the reviews where there are "problems" it appears to be less expensive 430w model.

In terms of cabling, the 600w supply has 2x PCI-E cords and will comfortably support (1) high-end graphics card. It will NOT support (2) high-end graphic cards, so you will need to look bigger (750w or more) if you are planning to go SLI.
