We definately need to get a better setup for measuring dynamic loads of real components. Tom's Hardware (Igor) and TPU do a great job, the rest, well, most measurements are closer to an educated guess than reality.

Sounds to me like the more glue the better. Coil whine has been a huge issue for anyone who's hunting for silence. Probably the reason why people complain about seasonics since they probably didn't glue down everything and their psus are quiet enough to make coil whine obvious.

Either way this is an amazing psu and I'm glad flextronics and corsair were ableo to pull this off. I'd personally never run more than one gpu ever unless the computing world majorly changes, but I hope they find ways to slowly trickle down the improvements to smaller psus.

Glue isn't always the best way to fight coil whine.

It may help. But if you need it to reduce coil whine, you already have done something wrong. So there is a design flaw in the unit or some components don't work well in that design.

That doesn't (neccisarily) mean that the components used are of low quality, it just means that those components don't work well under those circumstances and produce some electronics noise you don't want...

Irony of Irony.

Complainers going to complain.

Hence, a little insurance can't hurt.

As far as I know, coils always vibrate during normal operation in a PSU, but not always at frequency audible to humans.

Incorrect. The only way to eliminate coil whine without cement or glue is to eliminate the coils entirely. That's not happening in an SMPS.

Correct.

Correct.
There's plenty of people out there who could use some cement + gluing to remove their whine also.

Yep I meant voltage regulation, d'oh. What Delta units would those be BTW? I bet they didn't have 1500W of capacity...

Decent review and definitely a great power supply. However, it is a bit overpriced at the moment. I'll wait until the price drops below $400 before getting one And notice that Corsair recently dropped the price of the AX1200i to around $299 MSRP...
