Good point with that quote, however, to give answer, no, they are not good. They are tier 5 units, or at least they used to be. It seems there are a whole slew of new ones that haven't been reviewed yet, but I wouldn't expect them to be very good, and considering your location those units you have access to are unlikely to be these newer units anyhow.
 
80 Plus ratings are mostly meaningless when it comes to quality. They are only a measure of efficiency and not all units are even capable of running at what they are rated at. That's why we wait for reviews. And you certainly can't judge a unit's quality based on how much it costs.
 


The Chieftec NAVITAS 80 PLUS GOLD models are based on the CWT PUQ (G) series platform. Think Corsair HX750 V2 and HX850 V2.
 


It's Chieftec that decides and approves what component substitutions are made to the BOM (Bill Of Materials) since they are the customer of CWT. CWT just builds what the customer has contracted them to build.
 
Just read a couple of articles from ocaholic on the chieftec Navitas 650 and 1250w units. CWT seems to have built a couple of solid units, the only drawback to the 650w is the CapXon caps in the secondaries, but both have Nippon-Chemicon primaries, very good solder, ATX spec'd ripple and otherwise solid build. From everything there, I'd say the Navitas 650 would be a good candidate for tier3 and the 1250 for tier2

And yes, I understand that the client specs out the components etc, but that's not to say the builder has to actually do a good job with the build and any/all quality control, as was the case with the RM 750/850 that Chicony built, excellent build, solid quality all around, except for the base design which leant to such crappy thermal properties it landed in tier4 instead of the tier2 it could have been. Just from those articles I'd say CWT has actually picked up the ball this time and run with it, doing a respectable job on a good design, not something I've come to expect from CWT quality units.
 
Look at the bright side, the vs650 may not be a great psu, but it's tier3 and has at least a 3yr warranty and isn't a really bad psu. So you have a decent amount of time and coverage to now do some research, save some money, and make an informed and educated decision on your next psu without worrying about your current psu bursting into flames tomorrow like many tier5 psus will.
 
The VS/CX are only now just moved to tier4 from tier3 because they don't last very long per individual unit, usually 6months to 18 months on average. That's really crappy. But the unit itself has tier3 performance, build quality, output quality when it is working. Having a 3 yr warranty means if it does crap out, you get a new one, or maybe a refund, depending, and Corsair units aren't known as psus that go up in a ball of smoke and flames, they tend to just quit working altogether. So you are good, for as long as the psu works.

And yes, definitely better off than your friend.
 


I know a guy still driving an Edsel. But there are also 60,000 other people who received lemons when they purchased theirs. Some people can eat a salmonella infected cucumber and not get sick while twenty other people die. Just because somebody is using something and "appears" to not be having issues with it, doesn't mean that it's good or that you WON'T have issues using the same model.


Also, just because a power supply is "working", doesn't mean that it isn't also slowly damaging your other hardware, in small increments over time. People think, oh, my hardware failed because it got old. In many cases the reality is that , NO, it failed because your power supply slowly destroyed it. Something to think about anyhow.
 
There's a reason I call such things "PSU-shaped objects," unfit for purpose and nothing you want to connect to delicate electronics (e.g. computer components) if there is any possibility they will be connected to an A/C power source at the same time.
 
So... After a lot of searching I decided to save money to get a new much better psu to keep it for too many years and be safe (instead of upgrading gpu)

So i am thinking of the EVGA SuperNova 850 G2 and the Seasonic SS-850KM-X850W. I know they are both very good but which one you believe is better? Which one has more outputs? Also I think that I should get the supernova cause it has 10 YEAR WARRANTY and the seasonic 5years... Opinions??
