Catastrophic System Failure!! NASTY PROBLEM!!! - Page 4

post #31 of 34
And I hear the lower end PSU like the Corsair CX, even though it may produce decent power, it uses less expesive parts on the caps and whatnot, thus cutting down on the costs.

Of course, who am I kidding. I'm personally running a dangerously bad PSU ATM.

The only drawbacks I see to Corsair CX PSUs are very stiff cables (non-modular only), Samxon brand capacitors (not the best but not crap and at least as good as the Teapos found in OCZ ZS products), and SATA plugs that are a bit too short for some hard drive caddies and Seagate GoFlex drives.

I ignore those reviewers, but which relevant metrics did places like HardwareSecrets, JonnyGuru, HardOCP, XbitLabs, SilentPCreview, and TechPowerUp fail to measure? All of them measure amps as well as volts and apply full loads that are real full loads, not just computers running a video game.

And other than the drawback I mentioned, Samxon capacitors, exactly how are Corsair CX PSUs not built well? I searched some of your comments about them and found only Chinese components being mentioned.

Sleeve-bearing fan too, though those Yates do reasonably well over the long haul even in horizontal orientation, especially given the usual operating speed. It's mostly just concerns with long-term reliability. Some of the bad reputation may come from original CX430 / 500 / 600, which had undersized... somethings. I forget... maybe the switchers? +12V rectifiers? Supposedly current models no longer even use Samxon for the big primary-side hold-up cap because Corsair noticed a few RMAs caused by those blowing. But supposedly they haven't had problems with RMAs coming in based on those Samxon (and Teapo) secondary caps blowing, despite the harshing on those. Maybe more importantly, the series has a bad reputation of +5VSB coil whine.

As far as budget group-reg designs go, the performance is definitely there on the most CWT DSA variant units like the Corsair CX models based on that.

At some budgets and particularly at non-rebate prices, you might as well spend a bit extra or the same on something better, but CX is a fine option. I'm not really a card-carrying member of the anti-CX camp.

Not even 80 plus rated. Coonix has some that are, a 400, 600 and 750 watt. http://www.plugloadsolutions.com/80PlusPowerSuppliesDetail.aspx?id=190&type=2
