Closer Look

Upon opening of the package I was surprised to see a non-modulator power supply. It was after some research that I come to find out there are two models of the Chouriki 2 power supply; there is the ‘regular’ version (which we are reviewing today) and then the “Plug-in” model which is modular. The modular version is present on the Scythe EU site, so my guess is it should be available here in the States soon.

Getting back to our review model the first thing that stands out is the color, or lack of color. Scythe decided not to apply any paint to this unit. The unit was machined to give it a brushed aluminum look, topped with a nice polished finish. While it’s not quite my cup of tea and even without the black surface we are accustom to seeing, the Chouriki is a nice looking power supply.

Our 750 watt model, or officially titled SPCR2-750, is cooled by a large 135mm Kama Flex fan.  The 135mm fan is rated at 1250 RPM at 20dBA and was built around the mentality of having a quiet PC; and through our testing we find this to be true.

According to the specification sticker the Chouriki has some pretty impressive rails. Across the dual 12v rails there are a total of 95A producing almost 750 watts max.

Scythe uses what I like to call “industry standard sleeving” as the cable extensions are sleeved up to a safe distance from the plugs but still allows you to easily see the wiring that makes up each leg.

Testing

We know that testing a power supply on a loaded system is not the very best way to do so, but you can not overlook real world testing. Other sites have methods that use thousands of dollars in equipment to provide them greater detail. We have a trusty digital multi-meter. Those sites and the methods they use should be the true means of determining how good a power supply really is; however, we feel that showing you how it performs under real world conditions is also a valid measure of its performance.

Conclusion

I know when it comes time to purchase a new power supply that many of you look at stability, performance, price and even cosmetics. If that is indeed the case then you will get all of that from the Scythe Chouriki 2. One of the most important features of a power supply today is it’s efficiency rating, and the Chouriki 2 pulls off an 80Plus Silver for maintaining 85% efficiency at 100% load. 

We did not find the Chouriki 2 on Nvidia’s list of certified SLI power supplies, but according to Chouriki 2’s specs, it should be more than capable of handeling both SLI and Crossfire. Even the 750 watt model we tested had four of the 6+2pin PCIe connectors, which is sufficient enough for 2 high end cards or 4 mid-ranged cards (like the HD5770). If you are building a system that will need more than the 750 watts that this model has to offer, then there is still the 850 and 1000 watt models.

To re-enforce their pledge of quality, Scythe uses only high-end Japanese components and provides all the standard protections like: OVP, OPP, SCP, UVP, just to name a few.

The MSRP on the Chouriki 2 750W is to be around $130, but we will have to wait for retail prices as they’ve been known to deviate from the suggested price.
