Power Supply Roundup: 730W to 900W

Product Comparison - DC Outputs
To provide a better overview, we have averaged the results of the separate 12V rails into line for each PSU. All of the 12V rails were stable during testing and we didn't experience any major problems. The 12V rails of the OCZ ModXStream tended to be high, but this is still acceptable as they fall inside the specified range.
The 3.3V rails are equally good and we only see minor flaws at higher loads from most of the units.
The 5V rails also remain within specs, but the last two units (OCZ and Amacrox) are very close to the lower boundary at 100% load.

the efficiency charts are fantastic as you can see exactly how all the units compare at a specified wattagebut then you go back and do the acoustics charts by % load? why?
if i want to see how all the units compare at a 500w load, there's no easy way to do that as that might be a 68% load on one unit and a 55% load on another unit

Thanks for doing the charts in watts instead of load. I've been asking for that for some time. As has been said here it makes it much easier to find a good unit based upon a known wattage your system uses. Good article.tynopik - Friday, November 23, 2007 - link
great!and then once all units are tested to the same baseline, that opens the door for dynamic comparisons
as you build up a database of reviews, you could have a dynamic system where you can choose a 400-500 watt unit you reviewed 9 months ago and a 600 watt unit you just reviewed and it will generate the comparison charts on the fly
something for the future perhaps ;)

Could you please design and test with a machine that actually uses 700+ Watts of DC output?Jjoshua2 - Thursday, November 22, 2007 - link
I like the old review better. I don't have time to read the whole reviews, so I just read the conclusion and then go over a few interesting paragraphs. I hope you have a longer conclusion next time!Thanks.

Ehm there are 8 pages comparison/conclusion.... not enough?Of course people not appreciating the work and just read the last page find it boring... so next time I write a page about 10 PSUs and that'd be enough? ...

Check the hot deals section of Anandtech forums, a little while ago I posted a $50 price drop of the Silencer 750 down to a budgetable $150.

That would be a really good deal indeed.
