Review on HotTopStar Replacement H240AS 00 AC240AS 00 AC240ES 00 by Marcus Rash

I purchased this power supply for a Dell Optiplex 390 on January 9th 2018. It was installed in my car on January 13, 2018. After a little over 1 year of normal use, it failed on January 31, 2019. The amber power light on the front of the computer blinked. After replacing it with a known good PSU, the machine booted and performed as expected. If you don't plan on using this power supply for just one year, don't buy it!
