Why you should not buy a Corsair CX430/500/600 - Page 15

Almost every PSU nowadays is assembled in China, component resources are more or less the same between them using parts from specific ranges, and the same dozen of OEMs and known platforms are used from all manufacturers each time period.

So if Coolermaster for example prices their V series 850 watt power supply more than the Corsair AX860 or the Seasonic X KM3 850 equivalents, then there is no reason to get it. All 3 are the same internally and all are made by the same company. Getting the more expensive one doesn't make sense.

Let me start w/ an analogy ..... GMC sold the Envoy and Chevy sold the Trailblazer .... both are GMC companies and they both used many of the same parts .... the GMC Envoy sold for quite a premium above the Trailblazer, so did Envoy buyers overpay ? May features optional on the Trailblazer were standard on the Envoy .... some Envoy features were not available on the TB ..... some basic manufacturing details were different for example the front fenders on the Envoy were one piece with molded flares where the TB had two piece and a gasket. The latter design was subject to corrosion as road salt, slush and mud would collect at the gaskets.

So while many or even most of the components may be the same, without a careful takedown and detailed review, we can't always assume that various PSUs made by the same OEM are the same. So while buying by brand name may be a fool's errand, considering different OEM's, even basing purchase decisions by line while somewhat more reliable is oft unreliable also.... as we saw with the HX line ..... most were among the best ever sold but the HX 1050 and 1000 were just "average" performers. It should also be noted that while Channelwell makes most of the budget level CX and VX series, they also made the enthusiast level TX series and even the highly regarded HX series. Seasonic made the TXv2 series and the HX series froim 450 - 650 watts

The AX*60 series BTW isn't made by Seasonic, it's made by Flextronics....Seasonic made the 650, 750 and 850, Flextronics makes the 760i 860i, 1200 / 1200i.

And while many vendors buy "standard offerings" from OEMs, many prepare their own designs and then put those designs "out to bid" by OEM's. This is also true in other areas..... while Corsair's H series coolers for example are straight Asetek designs, Antec's coolers which are also built by Asetek and fundamentally based upon their OEM design, Asetec builds the Antec coolers in accordance with Antec's design and material criteria.

In short .....

1. There are PSU's which are terrible and should never be used.
2. There are budget level PSU's which are suitable for basic builds and if they meet the user's needs, there is no reason to spend more.
3. There are enthusiast level PSUs which will fit the needs of all but the most demanding users.
4. There are premium PSU but you are gonna pay for this level of quality.
5. Many vendors sell PSU's that fit into multiple categories above......the the better known brands for the most part avoid category 1.
6. While a "line" may usually be an indicator of which category a PSU falls in, there are exceptions to the rule.
7. OEM is not always a reliable indicator of quality as the OEM's also produce PSU's in multiple categories.

*cough*

To be fair any power supply can blow. Just last week I saw a HCP Platinum blow and that's the best PSU on the market in my opinion. It is quite funny that they were both on the front page at the same time though. tongue.gif

That's true. Comes down to individual circumstances I suppose. Anything can happen.
There's always a higher risk of it happening with cheap components though.

The ATX Specification requires no more than 5% voltage variation. If the numbers you quoted are correct and consistent, that's not likely to be the problem. Have you looked in event viewer ?

A 4670k can draw as much as 135 watts depending on voltage required at even 4.4 GHz and a 780 can reach close to 300. While the 670's were perhaps the best value hi performance product ever released (the Asus 670 got a 10.0 rating from techpowerup, only one ever) the 570 and 770 have not shined as far as OC'ing goes. If ya looking at a 780 and concerned about cooling as well as performance, read this:

Not exactly.
AX650/750/850 = Seasonic
AX760/860 = Seasonic
AX760i/860i/1200/1200i = Flextronics

I didn't list the 760 and 860 (no "i") as I had thought they were out of production.... hadn't seen them for ages but looking on newegg, I see that they are back, my bad.

Trust me. There are A LOT worse out there than CapXon. At least the CX is actively cooled.
post #149 of 230
Yeah, Corsair tends to enhance the components compared to the defaults of each platform. I've encountered it with their Seasonic units too. Sometimes the caps are bigger, sometimes the fets are stronger, sometimes it's something like bigger transformers or a combination of things.

But seriously, in the US you can get a gold unit with "japanese" caps for like 10-20$ more. Outside the US, Corsair units tend to be quite overpriced, to the point that they cost the same as some gold units with "japanese" caps from other manufacturers.

If you make a budget oriented purchase (the kind of purchase someone who'd get a cx would do) there is no point to go for it, apart from brand preference, which is the point of this thread.
If budget is not a concern, then you might as well go all out and get something exotic with catchy features and the likes, so that you can show off more efficiently and such. tongue.gif
post #150 of 230
For all the talk of the Samxon caps in the original CX 430/500/600 (which are like 3-4 years old with 2 year warranty), there haven't seemed to have been a lot of failures, right?

Current units have higher efficiency too.
