Street Price
€160?

Cougar is a new brand, a wholly-owned German subsidiary of HEC, which is a long-established Taiwanese computer power supply manufacturer. The GX-700 is 80 Plus Gold approved, a marque for the most efficient computer PSUs in the marketplace. At time of writing, the Cougar brand is only available in nine EU countries, not including the UK.

The GX-700 was not available from any of the retail outlets listed on the Cougar web site; the €160 price cited above is a guess based on the ~€130 and €180~190 prices of the GX-600 and GX-800, respectively. The GX-700 naturally goes up against other premium 80 Plus Gold power supplies such as the Seasonic X-650 or X-750, the Corsair AX-750 or the Enermax Modu87+ 700. Our GX-700 sample came directly from Cougar.

Cougar GX-700 FEATURE HIGHLIGHTS
FEATURE & BRIEF Our comment
MAXIMUM EFFICIENCY - Up to 93% of efficiency, compliant with 80-PLUS® GOLD efficiency requirement . See 80 Plus web site.
RST (RAPID SWITCH TECHNOLOGY) POWER - Highest efficiency performance with Rapid Switch Technology. Whatever that means...
DC-DC TECHNOLOGY - Provides highest efficiency, most stable performance, and perfect regulation (Regulation <3%). Refers to generation of the lower voltage lines from 12VDC.
CLC FILTER DESIGN - CLC filter design efficiently suppress Ripple/Noise ‹1%
OK.
HIGHEST DURABLE & RELIABLE SOLID CAPS FOR 12V,3.3V,5V - Solid caps for 12Vs, 3.3V, 5V provide highest efficiency, best reliability, and extend power lifespan. Not unusual these days in premium PSUs.
105°C JAPANESE CAPACITORS
105°C Japanese capacitors for uncompromised performance and reliability and 4 times the lifespan of conventional 85°C rated capacitors.
Not unusual these days in premium PSUs.
HIGH PERFORMANCE AT 50°C
Non-stop high performance and full rated wattage at 50°C/122°F ambient temperature.
Good.
HDB (Hydro-Dynamic Bearing) 14cm FAN
Best lifespan and super silent performance. Temperature-controlled design adapts rotating speed to PSU temperature. Even on its highest rotating level the fan is still quiet enough to be barely noticeable.
We'll find out.
DYNAMIC MULTI-12V - Automatic dynamic load distribution on multi-12V line provide power separately to the GPU and the CPU. If you are not using all output lines, the PSU automatically reroutes needed power from unused lines. This improves the performance and safety of the 12V lines for systems with multiple high-end graphic cards. It' sounds much like a single 12V rail behind all the marketingspeak... but let's give them the benefit of the doubt.
FLEXIBLE CABLE MANAGEMENT
Only about half the cables are detachable.
COMPLIANT W/ EUROPEAN DIRECTIVE 2005/32/EG (EuP) - Standby consumption is ‹0.3W. Good.
SUPPORTS ENERGY STAR 5.0
Not unusual!
FULL PROTECTIONS - OCP, SCP, OVP, UVP, OPP, OTP Expected.
5-YEAR WARRANTY Very good.

The multiple 12V lines usually means that there is a current limiter on each one. However, the claim about "Dynamic Multi-12V" suggests a single 12V line. The technology is not clearly explained, and which output connectors carry which 12V lines is not really identified.
