The SilverStone Sugo SG07 is a small form factor (SFF) case supporting mini-ITX and mini-DTX motherboards. Although small, it is targeted to users that want to build a powerful gaming PC, as it supports video cards of up to 12.2” (310 mm) in length. It is a hybrid case, with its body made of steel and its front panel made of aluminum. One of the highlights of this product is that it comes with a 600 W 80 Plus Bronze power supply, which we tested. Let’s see if the Sugo SG07 is a good pick.

By the way, we’ve have already reviewed two other models from the SilverStone Sugo family, the SG05 and the SG06.

The Sugo SG07 can be found in two versions, one with a transparent side window (SG07-BW, which is the model we are reviewing) and one without this part (SG-07B).

As mentioned before, this case has an aluminum front panel, but if you pay close attention, only the middle part of the front panel is made out of aluminum, the parts on the sides are made of plastic. The SG07 has two USB ports on its front panel and the traditional audio jacks. There is only one external bay, for a slim optical drive (i.e., originally targeted to portable computers).

On the bottom panel of the Sugo SG07 we have a washable air filter, which matches the power supply fan. This filter can be removed from outside the case, making it easy to clean. The bottom panel also has a mesh for helping to ventilate the video card.

The rear panel and the interior of the SilverStone Sugo SG07 are painted black. On the rear panel we have a switch for controlling the speed of the big 180-mm fan available on the top of the case (more about that in the next page), the reset switch, two expansion slots with vented covers, a tiny mesh above the expansion slots, and the AC receptacle for the power supply. It is interesting to note that the power supply is installed on the front part of the case, and this AC receptacle is connected to the power supply receptacle through an internal power cord.

Let’s now take a look inside the SilverStone Sugo SG07.

The top cover of the case is attached to the chassis using regular screws, but painted black. In Figure 6, you see the Sugo SG07 with its top cover removed. The highlight of this case is its top 180 mm fan (S1803212HN-3M). The switch available on the rear panel allows you to choose between two speeds, 700 rpm (18 dBA) or 1,200 rpm (34 dBA). This fan comes with a washable air filter that is very easy to remove.

Another ventilation option available in this case and that is very unique is a ventilation duct for the video card, shown in Figure 8. In order to use it, you have to remove the center piece of the rounded foam that comes with the product and install the resulting foam ring on the air filter, as shown in Figure 9. Then you need to screw the duct on the side panel, matching the position where the fan of your video card is located. Since the side panel has several holes, you will be able to perfectly match the position of this fan.

In Figure 11, you can see the inside of the SG07 with the top fan removed. Although being very small, this case supports video cards up to 12.2” (310 mm) in length and CPU coolers up to 4.6” (117 mm) in height.

[nextpage title=”The Disk Drive Bays”]

The SilverStone Sugo SG07 comes with one external bay for slim optical drives (i.e., optical drives originally targeted to portable computers), one internal 3.5” bay, and two internal 2.5” bays.

By removing the optical drive bay we have access to the hard disk drive cage. This cage supports one 3.5” hard drive inside and two 2.5” devices on its bottom.

[nextpage title=”The Power Supply”]

The power supply that comes with the SilverStone Sugo SG07 is a SilverStone SST-ST60F-SG, a single-rail 600 W power supply with 80 Plus Bronze certification. This unit is manufactured by FSP and, at least right now, it isn’t sold separately.

The power supply comes with the following cables:

  • Main motherboard cable with a 20/24-pin connector
  • One cable with two ATX12V connectors that together form an EPS12V connector
  • Two cables with two six/eight-pin connectors for video cards each
  • One cable with three SATA power connectors
  • One cable with one standard peripheral power connector and one floppy disk drive power connector

The number of connectors is perfect, as it allows you to install a high-end video card, the optical drive,  and up to three hard disk drives or SSDs.

We made a complete load test with this power supply. Let’s see how it fared.

[nextpage title=”Load Tests”]

We conducted several tests with this power supply, as described in the article, Hardware Secrets Power Supply Test Methodology

First we tested this power supply with five different load patterns, trying to pull around 20%, 40%, 60%, 80%, and 100% of its labeled maximum capacity (actual percentage used listed under “% Max Load”), watching the behavior of the reviewed unit under each load. In the table below, we list the load patterns we used and the results for each load.

If you add all the power listed for each test, you may find a different value than what is posted under “Total” below. Since each output can vary slightly (e.g., the +5 V output working at +5.10 V), the actual total amount of power being delivered is slightly different than the calculated value. In the “Total” row, we are using the real amount of power being delivered, as measured by our load tester.

The +12VA and +12VB inputs listed below are the two +12 V independent inputs from our load tester. During our tests, both inputs were connected to the power supply single rail (the power supply EPS12V connector was installed on the +12VB input).

Input Test 1 Test 2 Test 3 Test 4 Test 5
+12VA 4 A (48 W) 9 A (108 W) 13 A (156 W) 17.5 A (210 W) 22.5 A (270 W)

Final Result Pass Pass Pass Pass Pass

The performance achieved by this power supply was impressive. It could maintain efficiency above 85% during all our tests, peaking at 87.6%. It could easily have received the 80 Plus Silver certification.

Voltages were always inside the allowed range, and noise and ripple levels were always low, except at the +3.3 V output (but still below the maximum allowed). Below you can see the results for the power supply outputs during test number five. The maximum allowed is 120 mV for +12 V and -12 V, and 50 mV for +5 V and +3.3 V. All values are peak-to-peak figures.

Let’s see if we can pull even more from the SilverStone SST-ST60F-SG.

Below you can see the maximum we could pull from this power supply. If we tried to pull more, the power supply would shut down, showing that a protection kicked in, which is great.

[nextpage title=”Conclusions”]

The SilverStone Sugo SG07 is an impressive case for users that want to build a high-end gaming system inside a small form factor case, allowing you to easily carry your computer around. The only “problem” with this case is its price. At USD 220 (or USD 210, if you choose the model without the transparent side window), it is a little bit overpriced, even when we put the excellent 600 W power supply that comes with it into the equation.
