Example Input: It works, not sure what else to say. Edit: Just died on me a few weeks ago after switching to a new GPU. Worked fine until then but now it freaks out if I play games. Gonna upgrade to an EVGA.

Example Input: Came as expected. Packaged great. Nice and tight. That's typical for ipower though. I have purchased many things Over the years from these guys and have never been disappointed. So far this is working great for my seedlings. 3 of these side by side approx 2 to 3 feet apart and I've got hundreds of seedlings thriving. Low power usage and low heat u can't beat it for the price.
Example Output:
5
