You forgot the delta in the deltaTemp column header of the results table

why do I even see that O.o

Aside from that, great unit for high end rigs. Bring on the next gen graphics cards

I was taken back by the amount of amps that were on the 12 volt rail.

Impressive bit of kit. So many good products being released lately that we're almost starting to need a "OC3D top three recommendations" for catergories

Btw, did I miss the noise results? 100+cfm @ 30db sounds too good to be true.

Like the aluminium finish, just wish manu's would stop slapping big-ass stickers on them. We know what it can do, we've already brought it. Yeesh.

Good spot. The stupid wysiwyg editor keeps stripping those out randomly

Yeah even I was pretty impressed by how much that unit was pumping out, especially for its size.

I dont really like to make any official noise comments on PSU's these days, but in the new 'Performance Overview' chart there is a 'Noise' section which I rate at either Low, Med or High based on how noisy it sounds at full load with my ear pressed against it.

The Z1000M certainly sounded low - in fact it hardly seemed to increase the fan speed (or at least the noise associated with a fan speed increase) through any of the loads.

I'm looking into a fan bypass switch for the load testers so I can briefly turn the fans off for long enough to hear the PSU. Thing is, even the bloody oscilloscope has a fan in it, so its never going to be a perfect analysis.

Thanks Jim. I know noise is stupidly subjective (I've got a 19db fan that sounds like a hurricane) but PSUs can be a source of noise it's impossible to rectify, unlike other cooling, so it's an important part in my decisions (which is still a HX series one).

Just a reasonable "loud, not so loud, is it on?" is absolutely fine, so thanks

I must have missed it in the performance chart. Overwhelming information lol.

Yeah if you're just looking for the low-down then the new overview charts is probably the way to go. It shows the percentage of voltage fluctuation from idle to full load (highlighting those PSU manufacturers that set their idle voltages really high to compensate for the amount of droop at load), Average efficiency and noise.

I'm also putting together a top 10 chart at the moment which will be sorted in order of performance for all PSU' I've tested in the last year or so.

What if you make a fan connection like used in psu's with a 5-12v pot and connect the fans to it? You're already ripping open the psu anyway.

Sure it would not be completely accurate and still be subjective, but together with your while-testing super subjective measurements it should be a little more precise.
