The Cougar GX Fan (PLA14025S12M) is a seven blade design and is sourced from Power Logic. This is a Hydro Dynamic bearing unit (MTBF 150,000 hours) which is said to lower noise levels. Rated specifications, while not easily available online are said to be 100 CFM @ 1,800rpm. We will analyse this later in the review.
The Cougar GX PSU is a DC-to-DC design with synchronous rectifying. This is an HEC designed product.
The GX 1050W uses primary capacitors from Nippon Chemi Con, a popular choice. They are rated 420v, 390uF @ 105c. Secondary capacitors are sourced from Teapo. The rectifier bridge has a dedicated heatsink for added stability under load. There is full safety protection implemented (OCP, SCP, OVP, UVP, OPP & OTP). They claim that due to the CLC filter design that ripple suppression is very good.
A little off track here, but i would love to know the percentage of the market who buy 1000W+ power supplies. just coureous as they seem so damn expensive.
One of the most attractive looking power supplies IMO. their custom cabling job is stunningly good looking, its an area of PSU design that always seems like an afterthought. I know enermax do a nice job of them too.
Specs seem ok. and I wouldnt worry too much about +5V as those figures are close to spec. if it was 80mV+ or more it would be a problem.
I am looking at a new 750W. I dont run more than one card, but Id like the PSU ideally to be running at 50% load to keep temps down.
THis is way out of my price bracket, can anyone recommend a 750W psu at around £100?
Cougar/HEC is lying, the fan is not a Fluid Dynamic Bearing or Hydro Dynamic Bearing; the part number alludes to that with the 12SM on the end. Meaning it’s a medium speed, 12v, Sleeve bearing fan.
You can cross check this on Power Logic’s website. Beyond that, disappointing performance all around.
Hi Charles, thanks, good info!
not worthy of 8. should be 7. ive read another review of this and the results are quite poor. these results arent great either.
There are two ways to look at it. the psu is stable real world with high end systems, most people wont know. but does it excuse poor noise suppression? it shouldn’t, there are better alternatives, and this one isn’t even cheaper than the others.
I actually bought this as I wanted something high power and with good cabling. I got a deal on it locally for 50 off. I have been very happy, it is very quiet, looks great in my case and handles two high end video cards.
I am surprised the ripple results arent great. it hasn’t caused a problem for me yet, even powering a watercooling kit.
Just because some of the ripple results aren’t great doesnt mean it will be ‘unstable’,. the guidelines are set out as goals to achieve. some PSU’s are outside those parameters and are stable. but its still slightly weak in some areas as the test results show. They could do with revising it.
Also surprised to read the fan isnt hydro bearing. I thought I found that fan last month and it said it was.
How can they lie about a fan bearing system? isnt that illegal? Very little information on that product.
Charles we received the following statement: “The reason is simple – one fan number allows you to use the safety registration number for different bearing types.
POWERLOGIC SAYS:
Powerlogic make it the same code name between sleeve & Hydro, because of the safety registration issue
they will specially mark “Hydro-Dynamic” under the model number in the fan label”
Thanks Zardon, good info to have, I was wondering how they could get away with that. the pictures showed ‘hydro’ in them, but there is little information on the fan online.
The fan is the least of the problems. I can’t say this company have a great reputation. the forums on johnyguru are full of comments about them and the designs.
No thanks.
Good testing but the scoring is much too generous. I read a thread on hardocp or tomshardware and one of these units caught fire in a consumers home, he lost his computer. Avoid.
Hi Pranic, have you got a link to that thread please? The company want to investigate as they haven’t heard about it.
Hardware Secrets just reviewed their 750 watt power supply and rated it as a “cannot recommend”. Cougar specs are based on an operating temp of 25 degrees C. When tested at closer to real-world temps, the performance degraded significantly; even below the 80-plus bronze rating they proclaim. Seems that this company has some credibility issues.
