This is a genuine Dell 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 Motherboard you buy from is better than the motherboard you can get anywhere else. It may even last longer than the original.

Our There is a reason we have been on the Inc 5000 list of fastest growing companies 6 years in a row and voted Best Computer Store in Austin year after year. Service after the sale.

We are just a phone call or email away should you need help.

    I've purchased several refurbished motherboards from Discount Electronics for a Dell Dimension 4700, a Dell Optiplex 780 and, most recently for a Dell Optiplex 330. The customer service, tech support, shipping price and speed have always been exceptional. If you have a vintage computer that you like and want to keep it running, this is the place to go. Their boards are as good as new, if not better.

    Product arrived quickly, decent price for the age of system. Board did not work, and am waiting on RMA to get a replacement. Company easy to work with.
