Hi guys

I had posed a question on here before, but I don't think I had explained myself properly, so I didn't get the answer that I'm seeking... so here goes again.

I'm looking at possibly purchasing a new PSU with a view to overclocking my system. My only concern at the moment is keeping it all quiet.

There's a SuperFlower Leadex Platinum 1000w and a SuperFlower Leadex Platinum 1200w. Either of them will be more than sufficient for what I'm looking to do.

I'm aware that both of them keep the fan off when the system isn't under much load. From what I'm able to ascertain it starts to fire up at about 40% load or something similar. So, the question is, does the 1000w bring the fan on sooner than the 1200w one given the same load, or have I completely misread something?

I know that it doesn't work like this on the Corsair ones the 40% figure given was for just one model of PSU, but I'm completely in the dark with SuperFlower's offerings!

Thanks in advance.
 
My system spec is entirely within the boundaries, last time I gave my system specs and had a load of people telling me that it was overkill, and all of that. I know 1000w is overkill. I'm not asking if it'll power my system. I have no doubt that it will. Sufficiency of power availability is not at question.

The information that I'm seeking pertains to which PSU will remain quieter for longer, if either. If it's the case that they all start the fan spinning at a relatively similar wattage, then the obvious option would be to buy the one that matches my system's power requirements plus a margin to cover upgrades, etc.

If it turns out to be that the 1200w one keeps my system quiet up to say 400w, while the 1000w only does it to say 300w, then the 1200w one meets my needs better than the 1000w, regardless of how much of the available power that I'm not using.
 
That's what I'm using now! It does the job for my build (just about), but I couldn't push it any more than that. I'm hoping that by going for a huge PSU, there'll be more headroom before the fan kicks in... but that may not be the case.
 
Thanks for the multitude of recommendations! I don't really mind if it makes a bit of noise once the fan does ramp up (at that point I will have my headphones in and game noises blaring... along with case fans, CPU fans and those two 970s whirring away)... it's just when nothing else is making any noise, I want my PSU to be making no noise either, so it's the actual threshold I'm worried about more than the noise it makes when it does fire up.

But those reviews do seem to be useful. I'll take a look at them when I get home.

Thanks again. :)
 
That's basically what I was looking to know. I found a review that showed the 1000w turning the fan on at a lower load than the 1200w, but then when I looked, the ambient temperature for one was 35c, and the other was 47c! That makes comparing them really easy!

Looks like the 1000w it is.

Thanks for the help, guys. :)
