This is a genuine Dell Optiplex 790 USFF Motherboard. We have done more than just test this motherboard. Here at Discount Electronics we go one step further and replace any components that have potential to fail in the near future.
Sometimes motherboards have 'known bad components' such as capacitors that may bulge or leak. The presence of these may not cause failure today but will in the future. That is where the experience of our techs comes into play. They know what components to be on the lookout for and they replace them.
The result is that the Dell Optiplex 790 USFF Motherboard you buy from DiscountElectronics.com is better than the motherboard you can get anywhere else. It may even last longer than the original.
