In-Win Commander 850W Power Supply

Like most other components in the computer, a power supply is 100% required for the computer to function. Let’s see how the In Win 850w Commander does.



The power supply is sometimes misunderstood as one of the main components that every computer requires to run. When shopping for power supplies, sometimes we don’t understand exactly how important it actually is and tend to not give it some serious thought and even sometimes grab the least powerful/costly unit that we see. This is a very bad idea because the power supply regulates and protects all your other components, and when getting the cheaper units, they tend to die and most times they don’t go out alone.

In Win has been targeting the gaming market with the Commander lineup of power supplies and so far the units have seemed pretty impressive. Today we will be cracking down an 850w model from the Commander series, but first lets take a look at who In Win is.

Here’s the front of the box, kinda looks like its hiding something inside.

This is the back of the box that lists all the features and power specifications of the unit.

Here’s everything that came in the box. You can see all the supplied cables, user manual, included mounting screws and power cord, the power supply, and even a nifty little carry case/bag to slip the power supply in along with all the cables.

The only cable that comes pre-attached to the unti is the motherboard power cable which is, obviously, used by every computer out there. The left 4 plugins are for PCI-E cables and the others are for SATA drives and 4-Pin molexs. That lonely one on the far right is the power for the CPU.

Here are all the cables, you can see that each group and types of cables are labeled so that you can tell which one goes where.


This is the Commander installed in my Antec 900 2 gaming case. The installation of this power supply was a breeze compared to the other PSU’s I’ve used in the past. Afterall, this is the first modular unit I’ve ever used.



Test Setup & Testing Methodology
CPU Core i7 920
Motherboard ECS X58B-a
Case Antec 900 2
Memory Samsung DDR3 1333MHz
Video Card Leadtek 9800GTX
Hard Drives 640GB Western Digital
CDRom Drive Lite On Sata DVD Burner
Power Supply In Win Commander 850W
Type Of Coolers Used Cooler Master V10
CPU Speeds Used 3.3 GHz
Operating System Used Microsoft Windows Vista 64 bit Home Premium
Type of Software Used During Testing Prime95, WinRar, 3DMark06

To test my power supplies, I used a GB Instruments multimeter. Idle voltages were recorded after letting the computer sit for 15 minutes to ensure everything really was idle. Load results were taken while running 3DMark06, then Prime95 the WinRAR. Both idle and load results were the average of 3 testings.


Power Output Results(V)
Measured With Craftsman Multimeter
Power Rail OCZ GameXStream 700W
In Win Commander 850W
Idle Load
Idle Load
4.96 5.02 5.01
12v2 12.35 12.28 12.00 12.00
12v3 12.33 12.30 12.00 12.00
12v4 12.30 12.27 12.03 12.05
5.10 5.11 5.10

The test results from the In Win alone are astounding and compared to my older OCZ power supply, the In Win completely blows that thing away! At the most, the In Win moved from 12.04v idle to 12.00 load which to me seems extremely reasonable. As you can see these results show how well this power supply performs, so all that’s left now is the conlusion.


When designing this power supply unit, In Win has taken careful consideration to all the details and in the end provided an extremely well polished product. This 850w model from the Commander line of In Win PSU’s provides stable power across all the rails and passed everything I could throw at it.

The overall looks and appearances of the power supply are different than what the other companies have to offer which is what really sets this unit out from the rest of the group. Although it doesn’t light up your case with a bright LED fan, the green paint makes it look badass and the performance lives up to that. The modular design is especially cool, although not unique, because I don’t have to run all those extra cables to the back of the motherboard making for some neat and tidy cable management. Although your paying a premium price for the cool features and good looks, at $209 from the Egg, I would for sure say it’s worth it.
