It is hard to get excited about a power supply, but this one exceeded my expectations.
There is a BIG fan, plenty of power cables that are bundled logically and a "real" on-off power switch.
The IDE and SATA power cables are "daisy chained" which make cabling different drives in the same machine bays easier. Watch the routing of these long power cables to avoid fans.
Mechanically, It fit perfectly into my 5 year old Compaq Pentium D.
Electrically, no problems.
The fan is much quieter than the one in the OEM power supply it replaced, no more 747 take offs.
What's great about it: No Hassel Installation
What's not so great: Nothing
I would recommend this to a friend!

My old Best Buy rig I got for school had an old PSU that wouldn't support PCI-E among other things so I was stuck using the onboard video, which was horrendous. Bought this today and installed it along with my Nvidia 9800GT and things are looking much better, literally. Although the price online and the price in-store was different, I am still satisfied with this PSU. For a 400 Watt that supports numerous Sata and 1 PCI-E you can't go wrong. Just not sure why the price in store was $59.99 when it shows online as an in-store pick-up option for $49.99.
What's great about it: Good upgrade to use better GPU's
What's not so great: Price difference online vs. in-store
I would recommend this to a friend!

The power supply in my 4yr old HP computer died. This power supply was purchased to replace the original 350watt supply. It is a little more powerfull than the original and has all the right connectors. It even has more SATA power connectors than the original PS I replaced. It installed easily and has worked flawlessly. The fan in this supply is as quiet as the original, maybe a little more quiet. I found cheaper supplies at other on-line sites, but this one was available the day I needed it. I bought it at Best Buy On Line and picked it up an hour later with in-store pick-up. Overall I am very satisfied.
What's great about it: Has all the right connectors, quiet, installed easily
What's not so great: none

I had never replaced a power supply before and this one was recommended to me by the Geek Squad. I bought it and was able to install it into one of my computers with no problem. I simply set the computer on its side and as I disconnected each item from the old power supply I connected the item to the new power supply. It was very easy to install and would highly recommend this product to anyone to repair their computers.
What's great about it: ease of installation
What's not so great: bulkiness of all the wires
I would recommend this to a friend!

The troubleshooting of my computer down to the power supply was rather quick. The technicians worked on it while I was in the store but I had to leave and pick it up later. The computer works fine. The only negative thing I have to say is that someone on the geek squad broke a hinge on a front panel on my computer that hides my outlets. There was no compensation or we will try to replace that. They did try to fix it but realized they couldn't. Computers brought in for repairs should leave in the same condition plus the repair as when they are brought in.
What's great about it: quiet
I would recommend this to a friend!

What's not so great: nothing so far
I would recommend this to a friend!
