The Bottom Line

Aug 18 2011 - The ZT Affinity 7137Ma offers a good overall compromise for those looking at a general purpose system. It may not have the same level of performance as Intel Core i5 based desktops, but the AMD A8-3850 does offer more then enough performance for the average user. The best part is that the desktop comes packed with plenty of memory and storage space that users will not likely need to upgrade. The main drawback is that even with the integrated graphics that are good, the system is not really well suited for those looking to do some serious gaming as the low wattage power supply limits graphics upgrades.

Guide Review - ZT Affinity 7137Ma Mainstreak Desktop PC

Aug 18 2011 - Zt Systems is offering a very different PC at the $700 price range with the ZT Affinity 7137Ma. While Intel dominates the desktop processor market right now, AMD has released a very interesting product with their new Llano series APUs. For this system, they use the current top of the line AMD A8-3850 Fusion processor. It offers both an quad core processor and integrated Radeon HD Direct X 11 graphics built into the chip.

In terms of raw general computing power, the A8-3850 falls short of the latest generation of Core i5 processors from Intel. The closest Intel processor would be the Core i5-2300 which is also a quad core processor. For the majority of users however, the processor will provide more than enough performance for the applications they use. Only more demanding applications such as desktop video editing will really show that it is slower than the Intel processor. What is surprising however is the fact that Zt System includes a whopping 16GB of DDR3 memory in the system. This is double what most companies offer and means that it should run smoothly in heavy multitasking and have minimal memory slowdowns with tasks such as desktop video.

As mentioned earlier, the A8-3850 has an integrated Radeon HD 6550D graphics core built onto the processor. This is actually a very capable graphics processor that is even capable of casual PC gaming at lower resolution and detail levels. This should be sufficient for the majority of users looking at a general purpose system. What is nice about it though is that the internal graphics can work with an dedicated AMD Radeon graphics card in a CrossFire configuration that allows for additional performance. This means those looking to get a bit extra for gaming don't sacrifice the integrated graphics core. The problem is the Affinity 7137Ma only ships with a 350 watt power supply. This means that the system can only really only support the more budget oriented graphics cards which makes it not as well suited as a dedicated gaming system even with upgrades.

The system offers a large amount of storage space thanks to a spacious two terabyte hard drive. This is double what the average system offers in the $700 price range. The downside is the speed of the drive that relies on a slower spin rate as it is a green style drive. Performance isn't impacted too greatly though thanks to the higher density on the drive which does make up a bit for the slower spin rate. It is also nice to see that the system does offer two USB 3.0 ports for use with very high speed external storage to make for easy upgrades. A standard dual-layer DVD burner handles playback and recording of CD or DVD media.


Overall, the Zt Systems Affinity 7137Ma makes for a solid general purpose desktop system. The base configuration shouldn't require any real upgrading by consumers thanks to the large amount of memory and hard drive space. The only drawbacks is the graphics are a bit limited but it does make for a decent casual gaming PC and can be slightly upgraded.
