It's also fairly "normal" in terms of sound when you put it up there with the PCP&C or the Enermax :p
Seriously, you're making me having second thoughts about buying this next month, just because of the tone you are striking in this article
(Its good...for a cheap PSU ... That's maybe all you can expect from a cheap kilowatt PSU)
But when looking at the facts, it still comes out as one of the better ones out there >_<
+ The amount of pain(you've never overdone PSU's like this), it's like your just wanting to kill this PSU and make it die a horrible death to try and prove it's worthless, while in the end you're getting even more fed up with it just because the little bugger makes it out alive :p.

But here's the thing - if this were a HX750W it would be fantastic, and indeed we gave the TX750W an excellence award but not many people need 1000W PSUs. It's complete overkill for 90% of us. And for those that DO there are products on the market to pamper people and Corsair doesn't provide that. It doesn't have a UK RMA base and it doesn't have the hand-testing shindig that some of the ultra premium super-high wattage PSUs have. When it comes to 1kW the emphasis is less on price and more on total features and the Corsair, like many others, doesn't do absolutely everything - it's literally just a kilowatt of PSU.
The connectors fit well but the quality of plastic is not perfect and every review goes on experience. The model is virtually identical to the Thermaltake ToughPower 1,000W which is another CWT model - both have 5 year warranties, except the Corsair costs less. Now if I was to have reviewed a Thermaltake 1,000W and it got this result most people here would have said "Ah TT, must be **** and noisy".
We've tested the PCPC 750W to 850ish and that was perfectly fine, although very noisy. Corsair (subtly) challenged us to test it at 1,200W, so we did. I did strongly indicate we did not hold it against Corsair at all and it certainly does not affect the results. It does 1,000W perfectly fine - what it is rated to do. I rate 1kW models with a strong tone because they've got to offer something special since only few people need them - you don't buy a Ferrari without serious consideration for the extras an a driving test etc.
For those of you claiming it's super quiet - I'd suggest your rigs are quite hardware heavy or you're not loading it anywhere near the 1,000W it's designed to do.

Lights are all of 3W, and you'll not ever get a silent or even that quiet 1,000W PSU when you run it at 75%+ - they simply don't exist yet.
I'm testing the Cooler Master UCP Ultimate 900W next week - that's 80Plus Silver and a custom design by CM. Other than that Be Quiet! use a fluid bearing fan which is so quiet I can't tell it's even on without looking at it, however I cannot recommend the models above 650W because I haven't tested them.

But you seem pretty adamant about hand-testing BTW... Why is that going to be a Plus? IMO it only ups the cost of the PSU?
Meh, guess i'll be in doubt a little while longer
Compared to other 1,000W models it's not unexpected - you'll not yet find a "silent" kilowatt power supply, after all, even at 87 percent efficiency it has 130W of wasted heat to dissipate and most older models barely scratch much over 80 percent so that's 200W of excess heat.
