If you have an CX its not going to blow up or kill your PC, its not a crappy PSU, but it has some shortcomings about it which is what i will talk about in this thread.

Before i begin i would like to make it clear that this thread is about the old CX 430/500/600 NOT! the newer CX450/550/650

So i am going to make this thread and give you reasons why its not as good as many make it out to be.
Before i start i just want to say the CX750 is based on the CWT PUB-Q and not the CWT DSAII like the CX430/500/600 which is why i dont talk about the CX750 here.

Also i have not made or reviewed any of the data in here all of it comes from Techpowerup / Jonnyguru and google and a few other places.

So lets dive into more details.
CX 430/500/600 pictures (Click to show)
CX430M


CX500M


CX600M




Build quality (Click to show)
Now what i see here is a lot of cheaper parts, the main capacitor is a Panasonic but only rated for 85c not 105c like the better capacitors


The rest are CapXon´s from China which are not the best you could use.
Voltage regulation (Click to show)





Now this is not the worst voltage regulation in the world, but its not great either so the CX is a bit mediocre here.
Ripple suppression (Click to show)

Again this is not the worst in the world but its not great either again just average at best and mediocre at worst
Hold-up Time (Click to show)
The hold-up time is a very important characteristic of a PSU and represents the amount of time, usually measured in milliseconds, that a PSU can maintain output regulations as defined by the ATX spec without input power. In other words, it is the amount of time that the system can continue to run without shutting down or rebooting during a power interruption. The ATX spec sets the minimum hold-up time to 16 ms with the maximum continuous output load. In the following screenshot, the blue line is the mains signal and the yellow line is the "Power Good" signal. The latter is de-asserted to a low state when any of the +12V, 5V, or 3.3V output voltages fall below the undervoltage threshold, or after the mains power has been removed for a sufficiently long time to guarantee that the PSU cannot operate anymore.

Next is fact that the CX series is actually only rated to work at and below 30c (Click to show)
I will quote OklahomaWolf from his CX750 review on that as he can explain it much better and why its a problem on the CX series
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=416

Guys, this thing is only rated to full power at thirty degrees. I've spoken about this kind of thing before, but not for a while, so here's my position on this: I have no use for anything that can't do full power at forty degrees or better, and I review these units accordingly. Computer cases routinely see temperatures higher than thirty at the power supply intake, and this becomes more and more of an issue the further south you live, depending on whether or not you're buying this budget unit so you can afford to run the AC.

It also becomes more of an issue depending on where your unit is located. I have family with computers next to heating vents, because that's the only place available to put them. Guess what that does to a Canadian computer? Most of their cases don't have the newer layout where the power supply pulls room temperature air in from underneath the case, so those power supplies are taking in air heated by the vent and the computer hardware. Thirty degrees? Ha!

No, folks, thirty degrees just doesn't work for me. A unit this heavily de-rated is likely only good for 650W at a more reasonable forty to fifty degrees. It may be a perfectly decent little unit, but my hot box will not stay cool enough to make this unit happy. This is by design - my methodology is to get these things to at least forty whenever possible, because that's the lowest temperature I personally expect to get full power out of a unit. Forty is more than reasonable, even for a good budget unit.

Really, here's what it comes down to... this unit has to pass hot box testing, or there will be scoring repercussions on page six. I haven't had to use those particular scoring rules in a looooong time. Corsair, I hope you had CWT give you overtemp protection, because I think this unit is going to need it.

So all of these reasons are why the CX series are so cheap they are not all great and are fairly mediocre in most areas.
Does this mean that the CX is crap / trash / junk / garbage or any other such things NO! they are NOT! that bad they are just mediocre, but you should buy something better if you building a gaming and/overclocking rig and you can afford it otherwise you are just being cheap.
On the other hand if you building a very basic machine for office work web browsing media viewing and other light task a CX is perfectly FINE!.

Well, I think it's time to kill my overclock for a bit... It's a good PSU for the price, but don't expect any heavy lifting? That's what I got out of this anyway.

Doesn't Corsair design a PSU and then contracts the making of it to a OEM? I heard the AX1200i was like this.

But the CX series are designed/made by CWT entirely, correct?

Some models are like that yes

But in this case they just bought the CWT DSAII platform and slapped it into their own box and sell it as a Corsair unit

Good thread thumb.gif Some people unfortunately think that everything Corsair branded is pure gold. IIRC the original CX430 was pretty good value PSU but was later replaced with this cheap low quality platform.

My cousin used CX430M with his low end gaming rig. It was otherwise stable but he had odd amount of hardware failures, especially hard drives. I heard that ripple can slowly degrade and even break components so I took the CX430M out and replaced it with Super Flower Golden Green 450w (excellent value). Ever since the computer has been trouble free. Coincidence? I think not. I wish I had replaced it earlier.
