Wanting 'noiseless' PSU for system - Page 2

450W is indeed overkill but that's not a problem. Just look at the price.

VX450 does seem to be very quiet though in general, particularly for the loads you are going to be running:
http://www.silentpcreview.com/article751-page5.html

Note that that's an old review and compared to old units, since the VX450 is old. Perhaps the Antec High Current Gamer 400W (around 42£ incl. VAT on scan.co.uk today-only page) is quieter, as it has a larger fan and higher efficiency, and is likewise made by Seasonic.
Yes, though no linked reviews, that PSU is recommended on above sticky. Cheaper too. Whether it is quieter I do not know for sure.

This is what was in my mind when I said the fan doesn't spin, as per jonnyguru's review (refering to a box image):
"The next graph shown on the back of the box is a noise level graph. According to this, the fan does not spin up until the PSU is almost fully loaded."

As however the graph image shows a dAB reading at around 20, I am taking him too literally, I think.

If this fan is quieter, and indeed the 30A in the 12v rail ample, it would probably make more sense to buy this, right?

Ought the Corsair 430cx (actually 380w; CWT manufactured not Seasonic) be any good for my machine? 380w is still enough overhead, right? And does anybody know how loud it is in dAB?

See here:
http://www.overclock.net/power-suppl...cx-series.html

It is generally cheaper than the above power supplies, and gets a good review here:

http://www.hardwaresecrets.com/artic...-Review/1200/1

The grievance within the other thread seems mostly a politcal one and focused on being misled by Corsair on the PSUs testing methodology. Indeed Phaedrus2129 does not say the PSu is bad of itself. I'd most likely opt for a newish, second hand unit in any case, which I don't see as supporting this product line, so can't too exercised about the political ramifications in that scenario.

The CX430 would work well for your computer.

And would I need to split the cable for my CPU 4-pin plug? This is easy to do?

It has a 4+4 connector, it's designed to come apart, no worries.

You are missing reading comprehension. Page 2 of jonnyGURU's review states:
"The fan was so quiet, it was surreal. I kept having to put my ear right up to the power supply to hear anything at all. If I hadn't have seen the fan spinning, I would have thought it was a defective fan."

He doesn't say it doesn't spin. He said he saw it spinning, but couldn't hear it. That is understandable as his testing equipment has fans.

If you want to really know about the noise level, you need to read Silent PC Review's... review. Not only do they care about silence, they have the proper testing facilities (anechoic chamber). Page 5 of their review states:
"Beyond 250W, the fan speed and noise climbed quickly"

Thus, the PSU is super quiet up to 250W output, then quickly ramps up in fan speed/noise.

The CX430 is a 430W PSU. It is just how it gets that number which has thrown some people into a tiff. Also, initially there was an "armchair review" that stated it was a 312W PSU. I say "armchair review" because someone posted up pics of the guts, and other people looked at the pictures and went, "yup, looks like a 312W PSU to me."

Actual reviewers who used load testing equipment found that the CX430 can put out every single watt that the label on the PSU claims it can.

If that doesn't make it a 430W PSU, then apparently whoever still claims it is a 380W PSU must have a different way of calculating wattage than the rest of the world.

I do understand where they are coming from, because the CX430 has the +12v output of popular 380W PSUs like the Antec EarthWatts EA380. Still, a PSU is not rated merely by the +12v output.

I understood that perfectly well, thanks very much. Were it not for the graph I would have never figured him to mean that the fan spins at all below 400w, and as it was took the above in context of this.

I'll take a read through that - thanks.
