Cougar G1050 - GX 1050W Review

Introduction & Specs

Cougar PSU

I'm back!...

Some of you may have heard the rumours that I was reduced to a pile of smouldering ash after over-zealously pushing a Chinese made no-name 1500w (relabelled 500w) PSU beyond its limits last year. And yes, everything you heard was true. Unfortunately for me though, my esteemed colleague Tom Logan wasn't going to simply let me rest in peace. Instead he exhumed my body, (probably fondled it inappropriately -ed), and by combining the power of his 1,000 CPU strong J@H (Jim@Home) server farm, was able to re-animate me so that I could bring a steady stream of PSU reviews back to OC3D once more.

Of course, everything I've said up to this point is complete nonsense. But I think you'll agree that it makes for slightly more interesting reading than "The wife gave birth to our Daughter, and I decided to take a well deserved break"!

So, today is my first PSU review in almost a year. And what better way to get back into the swing of things than with a PSU from a manufacturer who simply refuse to churn out drab black boxes....


Cougar - Not just your best friends mum

Cougar first came to us in October 2009 with their 1000CM 1kw PSU. Fresh on the UK scene at the time we agreed to take a look and came back to them with some constructive criticisms regarding the unit. Much to our surprise, a month later they delivered a revised version of the PSU to our offices which addressed most of the issues and earned a recommendation from us.

Since then it would appear that they have been going from strength to strength, with a vastly expanded range of PSU's available in wide selection of outputs and designs. Today though I'm going to be concentrating on the latest and greatest model in the line-up, the GX 1050w. Let's get cracking....

Cougar PSU  Cougar PSU

Starting at the most logical place - the beginning, we can see that Cougar have changed their design very little from the original 1000CM unit. The theme is dark with a feint orange/gold pinstripe and a glassy Cougar emblem takes up the majority of space (almost like Cougar didn't really have an artist available to help with the design). Around the back of the box is the usual specs list in the four main Euro languages along with a brief explanation of some of the PSU's technologies and the obligatory rail layout diagram as reproduced below.

Cougar GX 1050w Rail Layout
DC Output+3.3V +5V +12V1 +12V2+12V3+12V4+12V5+12V6-12V+5VSB
Max Power 160W1008W6W20W

25A appears to be the magic number here as every single one of the rails barring the -12v and +5VSB is rated...well more likely that amount. The GX 1050w has a total of six +12v rails capable of a combined power output of 1008W (84A), which certainly will make my testing of the unit more involving. However, as most enthusiasts will probably tell you, there's no clear winner when it comes to single rail vs multi rail configurations, so I'm not going to get into that debate.

Up to 93% of efficiency, compliant with 80-PLUS® GOLD efficiency requirement .

DC-DC technology provides highest efficiency, most stable performance, and perfect regulation (Regulation <3%).

CLC filter design efficiently suppress Ripple/Noise ‹1%

The best solution for a High-End PSU by using solid caps for 12Vs, 3.3V, 5V, solid caps provide highest efficiency, best reliability, and extend power lifespan.

COUGAR® use highest durable 105°C Japanese capacitors providing uncompromised performance and reliability and delivering 4 times the lifespan of conventional 85°C rated capacitors.

Non-stop high performance and full rated wattage at 50°C/122°F ambient temperature.

HDB (Hydro-Dynamic Bearing)
140mm FAN Advanced HDB (HYDRO-Dynamic Bearing) fan provide best lifespan and super silent performance. Temperature-controlled design adapts its rotating speed to the PSU temperature. Even on its highest rotating level the fan is still quiet enough to be barely noticeable.

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 considerably for systems with high-end graphic cards in SLI® or CrossFire® mode and provides high voltage stability to keep components safe.

Other notable specs as extracted from Cougar's much longer list on their website, include impressive 93% efficiency, DC-DC voltage conversion and <1% ripple thanks to a 'CLC Filter Design'. These are all things we should be able to test over the next few pages, so it will be interesting to see if the GX lives up to the marketing spiel.

Inside the box everything is compartmentalised to minimise any transportation damage. Cougar have provided a generous bundle of modular cables along with some velcro cable ties and the usual mains cable + case screws. Essentially, everything you need to get up and running.

Jumping straight in with some pictures of the unit, we can see that Cougar have gone for an off-black wrinkle powdercoat finish complimented by a gold fan grill. This not only makes the unit look (and feel) quite rugged, but also gives the impression that you've purchased a premium brand unit.

Moving around to the back, we can see a total of eight modular connectors along with a small bundle of hard-wired cables exiting the unit. As expected, the red connectors are designed to used exclusively with PCI-E graphics cards, whereas the black connectors are for both SATA and Molex modular cables. Cougar has also thoughtfully printed the +12v rail number below each bank of connectors, making it easier to balance the load on the unit.

Now let's move on to the fun bit - dissecting the unit...

A bit expensive for my tastes, but a nice looking product nonetheless.

Welcome back Jim Quote

Jim is the PSU GURU period. It was your reviews that helped me to choose a PSU some time back, nice to see your LMAO reviewing style gracing the pages of OC3D once again.Quote

I have this PSU and it retails at less than US $170 here in the Philippines. Clearly at this price, its bang for the buck. Thanks for the review. It made me feel better about my decision to get the cougar GX1050w.

Great review love the way you have incorperated all the tech specs and put a video to it, I like the idea of this new theme and hope to see more of the same.

Keep up the great work guys! Quote

Nice one Jimbo mate. Great to have your reviews back.

By the way....

I personally like it and would be almosy tempted to build a PC around the design....

And then stop half way through and leave it to catch dust for a couple of years Quote

10-08-2011, 10:21:40

I like the look and the design of the psu, however it seems a tad on the expensive side, probably worth waiting till it cools down a bit, brilliant review as usual.

Also - "Cougar - Not just your best friends mum" - LOLQuote
