Shopping for cpus, motherboards & memory can look like a simple price decision, but the processor socket and desktop designation need to come first. The ASUS Intel PRIME H310M-A R2.0 and Dell XPS 8940 boards both use Intel and DDR4 wording, yet they are aimed at different hardware plans. Start with the machine or processor you are selecting around, then use price and condition to settle the decision.
Quick verdict
The ASUS board carries the lower listed price at $43.96, while the Dell board is listed at $161.58, creating a $117.62 spread. That difference matters, but it should not outweigh the socket and desktop-model wording. ASUS is the more natural route for a plan centered on LGA1151 and a MicroATX format. Dell is the focused choice when the board is being selected around the Dell XPS 8940 designation and LGA1200 processor entry.

Where each motherboard wins
ASUS Intel PRIME H310M-A R2.0
ASUS stands out for shoppers specifically looking for a MicroATX form factor. The title also includes an I/O plate, and the named ports include DVI and VGA. Those are concrete reasons to favor the ASUS board when they line up with the rest of a planned configuration. Its appeal is about matching that compact board description and named connection set, not treating it as interchangeable with a Dell desktop-specific board.
Dell XPS 8940 Desktop Motherboard
Dell's advantage is its named connection selection: RJ-45, USB 3.1, USB 2.0, USB Type-C, M.2, SATA, PCIe, and headset are all specified. Those listed interfaces can help narrow the decision for a shopper seeking those particular connections. The Dell board is also identified with a specific desktop model rather than only a general form factor, making it the more targeted choice when that model designation is central to the purchase.
Product notes
ASUS Intel PRIME H310M-A R2.0 LGA1151 DDR4 mATX Motherboard + I/O Plate
The ASUS Intel PRIME H310M-A R2.0 LGA1151 DDR4 mATX Motherboard + I/O Plate suits a plan where its two memory slots are enough for the intended configuration. The stated I/O plate adds a concrete item to the package, while DVI and VGA are named in its port list. Its important limitation is condition: the board is used. That calls for a different buying decision than Dell's new condition. Keep the focus on the ASUS board's own configuration and use it when the motherboard and processor requirements align with its stated design. The Dell model designation points to a different use case, so the two boards should be chosen by fit first.
Dell XPS 8940 Desktop Motherboard Intel 10th 11th Gen LGA1200 DDR4 K3CM7 427JK
The Dell XPS 8940 Desktop Motherboard Intel 10th 11th Gen LGA1200 DDR4 K3CM7 427JK is the direct choice when the purchase is for a Dell XPS 8940, the compatible model named for it. That clear model focus is a concrete reason to pick Dell over the ASUS board. A limitation comes from the processor entry, which identifies 10th and 11th Gen Intel Core processors and the H470 chipset. The maximum memory configuration is listed as 128GB; treat that as a stated capacity rather than a performance ranking. Dell's new condition is another defined distinction, but the XPS model and processor wording should lead the decision.
Final choice by use case
Choose the ASUS Prime H310M-A R2.0 for a MicroATX setup when its two memory slots suit your configuration. Choose the Dell XPS 8940 Desktop Motherboard when the board is being selected for a Dell XPS 8940. Finally, let the LGA1151 versus LGA1200 socket designation make the deciding call: that processor requirement is the clearest divider between these two Intel DDR4 motherboard options.
