30C internal case temperature. This is easily reachable during a gaming session or even simply during a warm day or with central heating on.
You do realise that the CX 430W which replaced the earlier CX 400W actually supplies less amps on the 12V line?? The CX 400W was rated at 40C:
http://www.corsair.com/products/cx/default.aspx
The CX400W is 80+ rated too unlike the CX430W.
The CX 430W is actually a 380W unit. Even Corsair themselves have said that they are not sending out any review units.
Even the DSA platform the new CX series are based on only goes upto 500W.

Given that most modern cases mount the PSU at the bottom of the case, 30C isn't a realistic PSU intake temperature in the UK unless you're in the middle of a summer heatwave or you sit your computer on top of a radiator. And it's not as if there's a 50% reduction of output as soon as you go over 30C anyway.
Actually most of the cases which will see a PSU like the CX430W will have a top mounted PSU mounting. Most cases under £35 still tend to have PSU mountings at the top.
How many people also have sufficient cooling fans in their PC then? Many people would rather have a slightly warmer running PC which ran quieter.
Another thing is that this PSU is being sold worldwide not only the UK.
Remember the FSP Epsilons then?? They too were only rated at lower temperatures and had over-enthusiastic ratings too. They were a disaster AFAIK.
Also,why are you making excuses for Corsair then??
So basically they are selling a PSU which actually provides less amps on the 12V line,has lower efficiency and is rated at a lower temperature and saying it is an upgrade.
It is funny that the CX 400W is actually rated at 40C and the CX 430W which replaces it is rated at a lower temperature.
Like I said before Corsair said they do not want to send out any samples for review.
The Corsair VX,HX and AX ranges are rated at 40C.

I'm not making excuses for Corsair, I just don't see any reason to get my knickers in a twist. The PSU will output more current than is needed for the target market, the budget end. If you start attaching a gazillion cable extensions and splitters and doubling your CPU frequency, you've nobody to blame but yourself when your PSU fails.
This is getting better!
The 450W VX450W actually only provides 1 amp less on the 12V line than the 500W CX500W:
http://www.corsair.com/products/vx/default.aspx
The 550W VX550W provides more amps on the 12V line than the 600W CX600W.
The VX450W and VX550W are also 80+ certified too.
So basically Corsair have jacked up the ratings by increasing the amps available on the 3.3V and 5.0V lines.
I don't like it when companies start mis-selling products based on brand name. You are making excuses for Corsair as you seem to condone them selling an inferior product which replaces a superior one at the same price point. Remember many people would think a CX430W would be an upgrade over a CX400W. For modern systems it is a downgrade.
The CX series now extends upto £60 and essentially replaces the VX series too. This is NOT budget PSU territory.

Another factor why a higher temperature rating is important is dust build-up as this decreases the cooling efficiency of a system. Most people will probably only open up a desktop to replace a component and not to remove any built up dust.
Again. I'm not making excuses for them. I'm just not making a mountain out of a molehill. And how is the CX430 inferior over the CX400? It'll supply 30W more energy to components than the CX400. Not only that, they're no longer over-provisioning current in the units design. Again, 336W on the 12v rail is more than enough for any budget machine, and even many mid-range machines.
For a 600W PSU. That sounds pretty inexpensive to me, compared to the cost of competing 600W units. The 430W unit is £37, and that most definitely is budget pricing in the contemporary PSU market.
???
Wrong.
CX430W:
http://www.corsair.com/products/cx430/default.aspx
Max Combined Wattage
120W
336W
9.6W
15W
CX400W:
http://www.corsair.com/products/cx/default.aspx
MAX COMBINED WATTAGE
130W
360W
9.6W
12.5W
The CX430W provides less wattage overall. The PSU is rated at a lower temperature. The PSU is not 80+ rated. It costs the same as the unit it replaced.
Even you think that the CX430W provides more power than the CX400W.
On top of this the CX400W has a three year guarantee and the CX430W two years.
You are making excuses for Corsair again.
Again they inflating the wattage of the PSU.
Here is a much better PSU for the same price:
http://www.ebuyer.com/product/245671
The Seasonic platform this is based on actually provide its rated power at 40C and the PSU is 80+ Bronze rated.
Here are the specifications from the Antec website:
http://www.antec.com/Believe_it/product.php?id=MjU5Ng==
3.3V and +5V combined maximum output: 130W
+12V1 maximum output: 40A(480W)
Total Continuous Power: 520W
Here are the specifications of the CX600W:
http://www.corsair.com/products/cx600/default.aspx
3.3V and 5V lines: 150W
12V line: 480W
The PSU is only rated at 30C and is under 80% efficient which is pathetic for a modern PSU.
So basically,the 600W Corsair is only providing 20W more than a 520W Antec. On top of this the extra wattage is on the 3.3V and 5.0V lines which is meaningless for a modern PC as most power draw is on the 12V lines.

Didn't you notice that the CX400W can output more watts on each line??
The CX400W is actually based on the VX450W and is more like a 450W PSU but is only 80+ rated upto 400W.
The problem is that you don't seem to realise that the wattage figures for new CX series are overrated and most of the "improvement" are on the 3.3V and 5.0V lines. On top of this none of the new CX range have 80+ certification.
In fact the CX400W by the new CX rating system should be at least a 450W PSU.
The CX430W is a 380W DSA platform PSU rebadged as a 430W one. The 380W DSA is 80+ certified BTW. The CX430W also uses a cheaper sleeve bearing fan whereas the CX400W uses a ball bearing fan.
All the OCZ StealthXStream II PSUs have 80+ certification. The OCZ StealthXStream II 400W is a 400W DSA PSU but is correctly rated and is 80+ certified.
I have a Corsair HX520W myself but the new CX line is just a triumph of marketing. Just because I bought some of their products does not mean I need to defend all of them either.

Well even in the UK we can have the odd summer day reaching 32-34, if you run your pc hard on a day like that what are you supposed to do? Watch your power drop off?
TBH I am not going to lose sleep over it be I can see why people get upset. What corsair is basically doing is trading on their reputation rather than on the quality of the product they are selling, although not illegal that is pretty cheeky.
30C is waaayyyyy too low an operational temperature. I wouldn't touch that psu with a barge pole.
Also consider the fact that there are psus that only cost £5 more around all of the new CX psus that are clearly significantly superiour and you see what a joke the range is.
CAT you missed out one of your favorite other points, the new CX range use cheaper capacitors, the old CX used japanese caps, the new CX are using taiwanese caps, I'm sure the primary are only 85c rated as well but I cannot find when I found that. so I may of been mixed up with another unit (on the 85c only)
And that's the thing that can really people off.
Many of us recomended the CX400w because it's a really solid unit, it was reviewed well and was good.
Now corsair has brought out a new de-proved version which they are not sending out for review so your average not so tech savvy person will do a quick look for reviews only find the good cx400 ones but will also find the reports of the new cx430 and incorrectly assume it's a new improved version, when it's actually a result of major cost cutting, production to cost and and excellent example of how to massage a PSU's numbers while still being legal.
Must say I'm worried about the new GS range as well, looks like something very similar is going on there.
