Review: desertcart SHOULD NOT SELL THIS - I didn't read the reviews before buying as this is such a utility item. Had a boot issue, got the card, put it in the PCi slot. The code display flashed once, then went off. Then found the board was now dead. I am not the first reviewer this has happened to. This is a hazardous product, wheel of death. You might get a result, you might fry your board!

### ⭐ AMAZON SHOULD NOT SELL THIS
*by A***G on 22 May 2024*

I didn't read the reviews before buying as this is such a utility item. Had a boot issue, got the card, put it in the PCi slot. The code display flashed once, then went off.

### ⭐⭐ Burned out my 12V rail.
*by A***. on 10 November 2024*

Tested it on my AOpen AX5T board, completely burned out the 12V rail running from the ATX connector to the PCI slots, destroying a bunch of via and components along the way, lifted the trace right of the board, with a big gap in between. Basically eWaste now. Test it on a dummy board before putting it in any board you want to keep.
