Zotac ZBOX MAGNUS EN970 Review - A Gaming mini-PC Done Right
by Ganesh T S on September 28, 2015 8:00 AM ESTPower Consumption and Thermal Performance
The power consumption at the wall was measured with a 1080p display being driven through the HDMI port. In the graphs below, we compare the idle and load power of the Zotac ZBOX MAGNUS EN970 with other low power PCs evaluated before. For load power consumption, we ran Furmark 1.12.0 and Prime95 v27.9 together. Despite consuming close to 19W at idle, the ZBOX MAGNUS EN970 actually happens to be the PC with the lowest idle power amongst all the discrete GPU-equipped machines that we have evaluated so far.
The load power is also amongst the highest in the set of numbers that we have seen till now. However, the big separation between the idle and load powers indicate that the sytem can operate efficiently over a wide range of loading conditions.
Our thermal stress routine starts with the system at idle, followed by 30 minutes of pure CPU loading. This is followed by another 30 minutes of both CPU and GPU being loaded simultaneously. After this, the CPU load gets removed, allowing the GPU to be loaded alone for another 30 minutes. The various clocks in the system as well as the temperatures within the unit are presented below.
According to Intel's official specifications, the junction temperature of the Core i5-5200U is 105C. We find that pure CPU loading keeps the clock frequency half-way between the base frequency (2.2 GHz) and the maximum burst frequency (2.7 GHz). However, the temperature remains well below the junction temperature (around 82C). Getting the GPU into the equation ramps up the motherboard temperature as well as that of the GPU and GPU. However, the CPU remains below the junction temperature despite going up to as high as 102C. The GPU stabilizes around 81C.

I have to agree with milkod2001, specially if you compare it with the base alienware alpha that cames with storage, OS and even a Xbox controller for half the price of the Magnus barebones.In order to make the Magnus compeling I would like a Quad-core CPU (even if it is a mobile part) and about $150 discount of the barebones price, then I would be all over it.

The Alpha that you're referring to that's half the cost has a 2 year old i3 cpu, 860M gpu, spinning hard drive, and 4 gb of ram. So yes, the Magnus is a more powerful, smaller device, and it costs more money. What's your point?Winterblade - Sunday, October 4, 2015 - link
That 2 year old CPU is a desktop part, should be about the same performance compared to the 5200U, and the GPU is a 860M OCed, so it will handle 1080 gaming just fine, also it has Windows already installed and even an xbox controller, it is ready to use out of the box and it is half the price, that's my point, 400-500 USD is the price these gaming mini PC's have to hit to truly compete with gaming laptops and DIY gaming PC.Jauffins - Saturday, October 17, 2015 - link
The Alienware Alpha can be equipped with any size 2.5" SSD, up to 16GB RAM, and a 2.9 Ghz desktop Core i5 (or i7), all for less than the price of this barebones kit. And my 4590T runs at 65-70c full load, not 100+. The only downfall is the 860m, and I must say I've been very impressed with what it can do, and have yet to run into an issue. As long as you don't expect either of these systems to run The Witcher 3 on Ultra, you're good.meacupla - Tuesday, September 29, 2015 - link
FYI, mITX PC can get quite heavy, easily tipping past 7kg, and they are, at least, 4x as large.My RVZ01 build is 14L and around 8kg.
Compared to a SFF that's 2.23L and probably not even 2kg fully equipped.

FINALLY, a very small form factor gaming box with a GPU fast enough to handle all 1080p console ports for the current generation!Unfortunately, the price remains dramatically just way too high. If this came in around $500 like the Alienware Alpha, I would buy it instantly. Of course that would be an 80% discount so obviously Zotac isn't at all interested in fighting on price.
That's what I really want-- an Alienware Alpha with a 970M GPU, as the 860M it comes with just isn't fast enough for solid 1080p gaming. Keep hoping the next-generation Alpha hits that performance level.

Ok but the Magnus has much better parts than the Alpha so why would it be the same price? The Alpha with the "comparable" specs is about the same price as the Magnus. And by "comparable" I mean the Alpha has a shitty spinning hard drive and a 2 year old Haswell cpu and 860M gpu...schizoide - Monday, September 28, 2015 - link
Nope. The CPU doesn't matter for gaming and the Alpha GPU is much slower.smorebuds - Monday, September 28, 2015 - link
What're you saying nope to? So what if zotac made an sku with an i3, 960M, 500gb HDD, and 4gb ram and sold it for $499 would you be happy? That's your alpha in 2015 except in a smaller package which is the whole damn point of this.Jauffins - Saturday, October 17, 2015 - link
I want to see the adoption of MXM. My Alpha is the perfect SFF system (2.9Ghz desktop i5, 16GB RAM, SSD) but in a few years, the 860m will start to show its age. Why nVidia isn't pushing this form factor, where I can spend maybe $200-250 to get an MXM form factor desktop 760 or 960, I don't understand.
