    So what should i get? :??:
  3. The CX is a quality PSU. It's just not the ideal choice for your application. If the price is right, though, it will work fine.
  4. The CX is not a good unit, its biggest issue is its poor quality secondary capacitors(capxon), they have a high failure rate and a low temperature threshold. The CX should not be used in a gaming system. A good quality 620w psu would run that system and will usually cost the same if not less. In the US the 750w Evga B2 is less than a CX750 and is a far better psu.

  5. The CX does not have a high failure rate. Yes, the secondary side capacitors are not that hot, and yes it is usually a bit overpriced. It wouldn't be my first choice, but it's not nearly as bad as you guys make it out to be. If you can get it at a good price and are on a budget, it's not a bad choice.
  6. Look through the forum i see about 5 failures a week just on these forums, id call that high. I have had 100% failure rate on the 5 CXs that bought a few years ago shortly after they released, 4 of them failed within thier first year 3 of them on systems under a low load using igpus. Have a fring who went through 3 cx750s in 2 years first lasted 18 months (longest ive personally seen one last) its replacement lasted 2 months and the replacement for it lasted 2 weeks. The vast majority of the failures have been bad secondary capacitors that shut down the psu under load. One of the CX600s i used had a cap that exploded. Im not alone in these expriences, others here have had similar problems. While they are not system killing garbage they are NOT a good psu and not a psu I would ever reccomend in a gaming grade system.
  7. The CX fail a lot, and it's not just the secondary always. There is the CX and the CX V2 power supplies which go by the same name, the CX, so they can be hard to tell apart, but some Corsair PSUs use Samxon primaries rated at 85C, too, or a Capxon primary capacitor.

    The temperature is another issue. They don't handle temperatures well.
  8. You should know better than to depend on anecdotal evidence, even your own. I know people who refuse to use seasonic after a string of failures.

    The launch CX DID have issues, but was long time ago. It's a stable unit now.

    The biggest problem with the CX is price point. It's a quality psu, for its class, but usually finds itself priced against higher class units. I will say that the 750 is almost always overpriced, but that might not be true everywhere.

    I agree with you in that I much prefer a better grade of PSU, but that's not the same as the CX not being up to the task. It's a mature, respectable, power supply.

    I'm guessing you own a CX and have bias toward it. I was once the same way a long time ago, trying to argue about how my EVGA 500W was good, but it is futile and wrong. The EVGA 500W is bad quality.
  10. Bias? The only bias on this board is anti-corsair, pro-seasonic/superflower/EVGA. I haven't purchased Corsair PSU since the CX400, which was the only CX based on the S12II. That was 6 years ago. I have not been happy with the direction they have gone since.

    However, none of that changes the fact that the current CX is a quality product. I wouldn't go in that direction myself, but I'm not the one buying. I owe the OP an honest assessment, not some fantasy about the CX having a 100% failure rate in the first year.
  11. Well, since "quality" is subjective I'm not going to argue with this over it, but "quality" for me must be different than "quality" for you. But there is a reason people are pro-Seasonic/Superflower/EVGA. Their power supplies are high quality for a good price. Just look at the EVGA 750 B2, which runs at $48 on NCIX right now with a $30 rebate. It's just incredible pricing. The EVGA GQ lineup also runs for a good bargain. You have the G2 running cheaper than any of Corsair's high-end offers such as the RM, RMx, RMi, AXi (well, that's Platinum and competes with the P2, but still). You get a 10 year warranty with some of these EVGA power supplies.

    I wouldn't call it bias toward EVGA, I'd call it mere realization that these power supplies sweep much of the competition. They're just really good. I'd like to argue why there are better offers, but there aren't.
  12. Can you guys give me a final answer for a good quality affordable PSU?

    it's all about the price: the 1$ is 3.91 here
    like 150$ is my max affordability at the moment
  13. Location? Sites you can buy from?
