That's why he quit doing reviews several years ago. To maintain the impartiality of his site.

Apparently, it didn't work. Seems the Wolf wants to keep his boss happy and knows which side of his bread gets buttered. That's not much different than us as unpaid moderators even. We're not going to knock Purch backed products or commentary unless it's pretty blatantly foul. Like with the ad blocking article. Rocking the boat too much creates undesirable results. It would seem like working for Corsair and maintaining an entirely indifferent perspective for a power supply review based site don't and could never, go hand in hand if impartiality is desired.

I don't see any way some of those units would have scored as high as they have were he not directly linked to the company. Not with the real world results we see and the conflicting scores from some other review sites. Then again, considering he DOES work for Corsair, I suppose they have SOMEWHAT kept things as impartial as could be expected, in most cases, but I'd still tend to think some of those units would have taken a few more hits on scoring were they not Corsair units.
 
For my part, I'm not going to consider the uncertainty of a Corsair when I can be much more certain about the quality of numerous other units. I suppose they might be okay in low-demand non-gamer builds, but that's it.
 
It's not like they explode on a regular basis. Yes, most people see the Corsair name and think quality but most people aren't computer nerds like we are 😀 And in all honesty all Corsair units are rated correctly for continuous output and not peak like some companies ( *cough* CoolerMaster ) do. A great many people use CX and VS units in high end builds and for a lot of those people those are the best choices just because of regional availability and pricing.

So no, their power supplies are not as good as they were 5 years ago in comparison to the competition but some of that is attributable to the competition stepping it up. And at the high end their units are as good as anything on the market.
 
As far as I know the only truly impartial testing is by HardOCP because they buy their units off the shelf. All the other review sites are sent samples.
 


Yes those units are pretty good.
 





What I posted there:

Just like to say howdy, decided to poke my head in over here and and possibly interject a comment here and there.

I wanted to make a suggestion for a review, not that you needed any, but it would be nice to see a retail review of the EVGA B2 850w and Corsair CX 850w unit's since the claims on them are so high. Considering the meh results of prior CX models I'm skeptical of the claims on the CX and the B2 850w doesn't seem to have a reputable, or any any other kind of review so far as I can see. I know it's a pared down version of the G2 Golden green platform but considering the B2 750w had a few checkmarks against it, although an outstanding unit, it would be nice to see how the 850w unit rates.

Concerning the CX 850w unit, it seems to have scored exceptionally high for a model series that has traditionally been somewhat lower in quality. As quoted from elsewhere:


Quote:
wolf seems to have a few marbles missing on the CX850M (Bronze doesn't have a 10% requirement). Unit was staring at a Silver rating until test 5, which was not 100% load, but did miss Wolf's 97% load by 0.137%, which is better than the XFX Core 850's actual 100% load results.

The load regulation on the 12v is not impressive. It survived to 47C but is only rated for 30C, which is horrid. 30C is 86F, which is open window weather for many.


To which was replied:


Quote:
I think Jonny himself needs to take a look at the CX 850, a retail one, because that seems to be a review unit if it did THAT well in the rigorous tests.


Just a thought for future reference.

I have 6 EVGA units currently in the pile, and am not too anxious to take on any more until these are done with. The 850W B2 isn't one of them, but the 750W has been reviewed: http://www.jonnyguru.com/modules.php...Story&reid=393

That was a retail unit.

My CX750M came from the same source as the CX850M and performed significantly worse with some major build quality issues. Both were review samples, so I'm not sure how anyone could argue Corsair cherry picked them. I personally have no interest in exploring these units any further... they're no longer relevant in the marketplace.

That 750W was almost bad enough to offer them a chance at sending a second sample. I certainly thought about it.

I have been doing 10% load for all reviews for years now. Only recently did I decide to move that load level into the main tests. The 10% efficiency figure is not scored on unless the unit is Titanium.

My question is, how can they no longer be relevant in the marketplace if the review is on the front page, first article, on the Jonnyguru site?
 
I don't know what your original post was, but his answer looks reasonable. I do remember the move of the 10% test into the regular loading not too long ago.

Edit: I would say they're not relevant because they are either hopelessly outclassed or there are too-much-better prices from competitors.
 
Yeah I think he means they are so bad there is no reason to give them another chance. There is just always a better choice at the same price range. I sort of got that from his review of the 850w so I was wondering where people were getting it was a good review.
 
Sort of wondered that myself. Even at that, I think it got an 8, which is higher than the 7.1 the cx750 got, but still pretty lousy. The EVGA B2 750w got a 9 so those units wouldn't seem to be playing in the same league at all.
 


I don't see any reviews at least not in English. If it can really supply 46 amps on the 12v rail then it should be labeled as a 550w unit not 700w and that assumes it can put out what it's rated. No 80 Plus certification and a single 6+2 pin PCI-E connector.... I wouldn't use one.
 
Oh dear, its bad when zip ties being included is one of the only good things a review can say about a power supply!
 
Glad to see my PSU is tier 2 (Seasonic M12-II EVO) good little power supply, love the flat black cables and that its fully modular, decent price as well. Gonna use it again on my nephews ultra budget/scrounged build (the only part im not gonna scrimp/go second hand on, plus I can alway use the unused cables in my own pc if I need them)
 
I think it is also necessary to consider the usage. I'd like to think even a tier-3 PSU ought to be able to survive HardOCP's 80% load test for what, 12 hours? I know it simulates a marathon gaming session...
