The Bottom Line

If you don't want to run Microsoft's latest operating system and have a very limited budget, then the ASUS K30AD-US002O is probably the desktop that you are going to get because it uses Windows 7. The one downside is that consumer will notice that the system features a bit less performance than a Windows 8 system at the same price because it features a slightly slower processor and Windows 8 has a bit better memory management. It still has enough performance for the average tasks that many people need a computer for.

Review - ASUS K30AD-US002O

The main reason that most people will probably be interested in the ASUS K30AD-US002O desktop system is less to do with the hardware but the fact that it ships with the Windows 7 operating system. Many people have actively avoided the new operating system but now more companies are realizing that there is a demand for it. The one downside seems to be that users looking to get the old operating system seem to have to sacrifice a bit of performance to get it probably because of Microsoft's licensing costs.

Powering the ASUS K30AD-US002O is an Intel Celeron G1820 dual-core processor. While the Celeron name is generally associated with low performance, this is actually based on the Haswell chip architecture that is similar to the latest Core i3 processors. The difference here is it runs at a lower 2.7GHz clock speed and does not feature Hyperthreading. This does mean that the performance will be lower particularly when multitasking but it still provides enough for basic computing tasks like web browsing, media streaming and productivity. The processor is matched up with 4GB of DDR3 memory which is a bit disappointing. It is smooth enough with Windows 7 but it really can benefit from being upgraded to 8GB total.

Storage is fairly typical of a very basic low-cost computer. It uses a 500GB hard drive that is less than half of what many desktop systems now come with. This will be a problem mostly for people that store a lot of digital media files, particularly high definition video. If you do need to add extra storage space, there are two USB 3.0 ports for high-speed external storage. The only downside is that they are on the front which means they are easy to reach but if you are going to have an external drive connected all the time, the cables will be highly visible. At least there is space inside for adding a second hard drive. There is a standard dual-layer DVD burner for those that require playback and recording of CD or DVD media.

As this is based on the Haswell processor, the ASUS K30AD uses the Intel HD Graphics but it has been tweaked a bit. It is still not something that you would want to use for 3D graphics and gaming although it can run games at the lowest resolution and detail levels if necessary. What it does provide though is some solid performance with Quick Sync Video compatible applications when encoding or decoding media. Now if you want faster 3D performance, it is possible to add in a PCI-Express graphics card to the system. The only drawback is that the power supply is limited to 250 watts, which excludes all but budget graphics cards that don't require additional power such as the GeForce GTX 750 cards.

Pricing for the ASUS K30AD is $400 which seems a bit high given the features of the system. For instance, the Dell Inspiron 3000 can be found with a faster Pentium G3220 processor and double the hard drive space for roughly the same price. The big difference here though is that the ASUS comes with the Windows 7 software which is a compelling enough feature for many people that want to avoid using Microsoft's latest operating system.
