ASUS K751MA-DS21TQ is a new mid-range laptop coming from the world-famous Taiwanese electronics company. A distinctive feature is the touch display with 17.3″ diagonal, suggesting a desktop replacement rather than a real portable laptop. But how about its performance and value for your money? I’ll tackle these questions here!


Intel Pentium N3540 is the name of ASUS K751MA-DS21TQ’s processor. Released in late 2014, it features a quad-core setup and clock rate of 2.2GHz – 2.7GHz, the latter when turbo is activated. Despite these solid specifications it’s not too power user friendly, as it receives only a low 1800 points in the popular Passmark tests. In comparison, the real low end processors like Celerons get around 1000 points. For mundane things like web browsing or MS Office it works fine, but somebody with heavier programs would probably find the Pentium too weak.

The memory amount is however excellent. There’s 8GB DDR3L installed and according to several vendor pages it’s also the maximum the system supports. You don’t have to worry about that, since the current 8GB covers pretty much all the activities you’d do with this rig.

The hard drive capacity is 1024GB so there shouldn’t be any problems with storage size: high resolution photos, games and pieces of music can all be put there in very large quantities. But some people value speed over storage, and if that’s you, the 5400RPM rate might be disappointing. In that case, consider tinkering and remove the hard drive and install a fast solid-state drive.

Display and graphics

17.3″ diagonal is large, more than an average size of 15 inches. It works well for home and entertainment use, but the 1600×900 resolution could bug some especially when you can sometimes find Full HD screens for this price. However, if you’ve wanted to test Windows 8.1 (64-bit)’s latest features, you’ll find the touch support an useful thing. Casual users are probably satisfied with this display, but professionals might want to keep searching.

ASUS K751MA-DS21TQ has the Intel HD (Bay Trail) graphics engine speeding up your games. Of course, the “speeding up” part is quite minimal. It’s a sluggish integrated unit, good only for games with low system requirements. For example, new 2014-2015 action titles don’t fall in that category, with most of them getting unplayable frame rates below 10. I would expect Battlefield 4 reach 15 FPS tops on low details. However, if you’re a friend of older or otherwise lightweight titles like WoW or Minecraft, you should do fine if you turn most eye candy off.


Three USB ports are offered, one of those being USB 3.0 marked by a blue connector. Next to the USB ports there’s a HDMI output which lets you to hook up a HDTV or external PC display.

ASUS K751MA-DS21TQ has a 10/100Mbps Ethernet RJ-45 port and 802.11b/g/n WiFi for Internet. People with mobile phones might also like the enabled Bluetooth 4.0 which can be used to easily transfer small files from devices to the laptop.

A DVD writer is installed on the right so you don’t have to worry about using an external drive. SD/MMC/MS card reader is likewise there, giving you another means of data transfer or temporary storage.

For video chatting, the laptop features a built-in webcam and microphone.

Any other things to keep in mind?

It’s no secret these big notebooks are not too road warrior friendly. On Amazon, the weight for ASUS K751MA-DS21TQ is 7 pounds, although several other sources list a 6.2 pounds weight that is probably the correct one. The 4-cell battery has a maximum run time of 5 hours.

The keyboard has a numeric keypad on the right hand side. However, there are no backlight available.

Wrapping it up

ASUS K751MA-DS21TQ is a big laptop for casual users. I say that because performance of the Pentium processor is not great, and for a laptop of this price it’s a bit strange choice. However, there are other features that compensate, such as the large touchscreen and excellent hard drive size. If you don’t want absolute power but a decent laptop for everyday computing, this Asus should not disappoint you.
