Pros: It works and is very easy to install.

Cons: My negative comment is just in regard to the COA and key code. I'm a retired system builder and this is the first build I have done with Win 7. The COA was on the plastic DVD case, but it is only 1/2" x 1 1/2". The product key is printed in black ink over a blue background and I had to put it under a magnified light and turn it at angles to finally read the key code. I really don't know what Microsoft had in mind by making a key code almost impossible to read. If at some time it is necessary to reload Windows, there is no way the key code can be read with the COA attached to the chassis.

Overall Review: Before retirement I built a ton of machines with 98, ME, W2K Pro and XP. I have never seen a COA that was this hard to read.

Pros: I'm an OEM builder and use mostly PC P&C 610 and 750 watt units. This is the 1st low wattage unit I have used for a special application.

Cons: +12v aux connector needs to be about 4-6" longer. It reached the motherboard socket, but I couldn't route it exactly like I would have liked to run it.

Overall Review: Tested the unit before installation and Power Good signal response time was 390ms. This was higher than I would have liked to see, but I'll just wait and see how the unit continues to perform.

Pros: Using it an old Dell Optiplex 7020, works great with the Windows 10 drivers from StarTech.

Cons: None so far.

Pros: Shipping was fast, and the works, what else can I say.

Cons: No cons whatsoever.

Overall Review: I would purchase this drive again, and recommend to anyone needing an inexpensive drive.

Pros: What can I say, it's a computer and it's working today.

Cons: I am a retired Microsoft OEM Partner/Builder, and during startup/activation there were some numbers texted to me for startup/activation, and FOUR times the numbers texted to me were incorrect. I finally figured out the code that was being texted and got the machine running. The machine is nice and clean, and seems to be running ok, EXCEPT the external sound port is not operating.

Overall Review: Seller needs to provide better set up instructions. As a previous OEM builder, I got it running, but some people might have problems due to the lack of instructions.

Pros: None that I can see.

Cons: Watery, poor transfer footprint from processor heatspreader to heatsink.

Overall Review: Purchased a tube to test. Tried it in my test machine with both an Intel P4 631 and an Intel C2D E6700. Tc temps averaged 5-6° hotter in BIOS at idle than with 2 other well known thermal compounds. I'm a professional OEM builder, and this stuff went in the trash immediately after testing.
