Power Supply Roundup: 730W to 900W

Hiper 4M880 and 5X880 - 880W
The second series of Hiper today comes with a different design and a different internal topology. The 5X includes eight USB ports and an additional port that can support up to 1A while the PC is off. This PSU also comes in a nice, shiny paintjob. Due to the USB ports on the back, the venting holes only occupy the upper section.
The 4M has no USB ports and a has normal black matte coating, but the space where the USB ports would have been located is still closed. Hiper started the idea of keeping the housing open with a mesh a long time ago. This idea has pros and cons since we might have increased problems with EMI and the airflow could also recycle back into the system. During our tests we couldn't answer the EMI question since we lack the proper equipment, but we might be able to help out with the venting issue since we didn't find any negative temperature results with the actual design.
Both units are the same inside and therefore we see the same data on the labels. The first two 12V rails are rated at 18A and the second two rails at 30A. The both 30A rails will be powering the graphics card PEG connectors, which makes sense.
Cables and Connectors
The cable harnesses look nice and sleek, and we see a slightly different harness output from the housing than we have seen before. Hiper doesn't have one big hole where all the cables are pressed through. Instead, the different harnesses are pressed in groups of two to three harnesses through five different openings. The benefit is that it's easier to access the different harnesses when you want to attach a new device since the connectors are not mixed.
The cables are quite short and especially the Molex connectors have a very short length. However, it's clever to make the graphics card connectors of different lengths since the cards always sit on top of each other. There are two harnesses for the graphics cards, each with one 8-pin and one 6-pin connector attached.
The inside of the Hiper unit looks very similar to a well-known manufacturer. We won't name names, as Hiper made many changes to the internal design. There are several smaller heatsinks inside; the secondary heatsink remains as a single unit, while the primary is made up of three smaller heatsinks that cool different components like rectifier bridges and diodes.

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?
