Power Supply Roundup: 730W to 900W

Silverstone OP850 - 850W
We have seen already two other versions of this unit before in the 650W class. The 850W version doesn't differ too much, and from the outside it looks the same. On the inside, however, there are plenty of changes, including a new topology. The power supply comes in a black housing with a large 120mm fan.
As we have seen before the OP850 has just a single 12V rail which supports up to 70A.
Cables and Connectors
All the cables are sleeved as usual. The mesh starts outside of the power supply which is not as attractive. If a company pays for the additional costs of adding sleeves, they should do the job correctly and start the mesh inside the power supply chassis. Other than aesthetics, though, there's no disadvantage in this approach. The cable harnesses are very long and have a maximum length of 110cm for the floppy connectors and 100cm for the Molex connectors. There are six Molex and SATA connectors, which is enough though a few more wouldn't have hurt.
The inside is nicely arranged and makes a good impression. There are two large heatsinks that reach from front to back. The fins are thick and should provide ample cooling. However, our measurement of up to 90°C in the heat-chamber is quite high. With an exhaust temperature of just 58°C, it appears the airflow isn't removing heat from the heatsinks. Instead, heat builds up inside the housing, which is not the intended result. Still, the power supply did complete our tests and we couldn't find any major problems.

The arrangement will be changed next time ;)What about the amount of PSUs? Too many?

I like the voltage vs. load charts used previously better than the bar charts. Obviously impractical with a 10 PSU roundup, but I hope they come back for smaller articles.Would it at least be possible to keep a consistent order to the PSUs, instead of sorting by output voltage? On the 3.3V charts on page 4 for example, it's confusing to have the Hiper 730 at the bottom of the 20% chart then the top of the 50% chart.

The first graph on page six seems to be missing the results of the silverstone.rickon66 - Thursday, November 22, 2007 - link
I love it when folks complain without even reading the review."Maybe you just forgot to upload the final page?"
Maybe you just forgot to read the review!!
Anyway-Good job on the review.

Good job guys, the o-scope readings/explanations are particularly nice =D.SOLIDNecro - Thursday, November 22, 2007 - link
No "Final thoughts" or "Conclusions"???A summary report is one of the most important, if not most important part of any article, to leave it completely up to the reader to draw conclusions based on charts requires to much time and expertise for your average reader!
Also your "Editors" choice awards are invaluable, you guys are the "Pro's" and should be able to guide the reader to what you would purchase for your own rig, and why it stood out from the rest of the pack
Maybe you just forgot to upload the final page?

So whats so hard about making your own conclusion and thinking a little bit?Editor`s awards are bogus!
Grow up dude!

Editor choice rewards awards are bogus!You can read and comprehend - can`t you?
Make up your own mind!

Just check the new arrangement. I wrote the comparison first and if somebody is interested to know more about a product he/she can check details after. The conclusion is on page 8.ChronoReverse - Thursday, November 22, 2007 - link
I find it rather confusing that way. I also thought that there was no conclusion until I read the comments.That said, I do usually read the conclusion first. Perhaps it should go back to the end and then a short abstract placed in the front?
