Gigabyte's New Odin GT 800W Power Supply

Inside, Cont'd
Some readers might have already recognized the little silver/clear dots on the heatsinks. These are actually LED lights that will shine out of the power supply once it's powered on. Don't worry: the lights can be switched off through the software if you so desire.
There are a total of four LEDs installed in this power supply. They shine through the fan into the system when active. They provide blue lighting and look a little like UV light, but as they aren't true UV lights UV-active material will only glow slightly in the dark.
Secondary Side
The secondary side is packed and the components are hard to see. There's a big PCB on the edge of the secondary side that includes all the controls and power connections for the system cables. The fan and temperature diodes also connect to this PCB. There are so many cables that it's impossible for air to come through to cool components under it. Unfortunately, we weren't able to see the capacitors' manufacturer(s) or their rating, but we didn't want to dismantle the unit any further for fear of damaging it prior to testing.

hi everyone,a noob here. I was wondering whether to get this PSU for my upcoming rig. I'm gonna run a quad core q6600, 4 sticks of ddr2 RAM, and a gf 8800GT (maybe SLI later). I was wondering, if the PSU is rated at 800w like the one being reviewed, does that mean that it is powered constantly at 800w or will the mechanism in the PSU determine the actual power consumed? Also, the author mentioned that there are a few PSUs that peform equally to this unit but cost less, can I know which ones are they?
Thanx.

about to buy a new PSU, want something future proof and modular. This looks about perfect for my needs. I find it odd that my Ultra X, which is years old and was the first Modular PSU. Still has better looking cables than any other modular unit on the market. Gigabyte seemed to step up the modular appearance a bit though. Kudos to them for that.wrong - Wednesday, July 25, 2007 - link
I can think of an excellent reason to honeycomb the side wall and put a sheet of plastic in to block airflow.Weight.
Not necessarily what they had in mind, of course. But LAN boxes should be light, and this could be one way to cut weight without reducing heatsink size and compromising cooling performance or noise.
I wonder if it makes a difference to EM noise.

I really really like the way you do these PSU reviews. Much more informative indeed than anything else on the web. I am a bit dismayed over the way AT reviewers sugarcoat conclusions on obviously poor performing equipment - tho I understand why you have to do it.Now heres a review I would like to see......
There is a just out new Coolermaster MODULAR 1000W PSU with humungous rails

Heres the first review.......

This is the new esba model, NOT the current emba
Note in the review are the usual stupid useless graphs showing "rock solid" unchanging rails. Since I am about to buy, I would love to see how your review compares. And this is modular so it might help in your investigation of this modality.
Keep on truckin'

Totally agree. It would be much easier to see where your system typically falls on the efficiency graph.
Also, on the 'Power Loss' graphs, the upper line should be input, and the lower one output. Oh, and watts are power, not energy!

You should pictures of the LEDs, but there should have been a lights out LEDs enabled pic :)Good article though, and the build quality looked fantastic

I assume that the software is only for windows? Of course the power supply will operate without the software but it would be nice to use the product to it's full potential with any operating system. In future articles please tell us if there is software for linux or not.Vidmar - Tuesday, July 24, 2007 - link
While I think the Efficiency charts in load percentage are nice, if you included Efficiency charts in watts it would be more informative from a buying perspective.The reason? I know the sum of system load is 375watts normally. The way it is now, if power supply XYZ has a max load of 650watts, I have to calculate where my ~375watts falls into that load chart (~57% load). But if the next power supply has 1000 watts max, then I have to yet again calculate what load percentage that may be for *that* power supply. If the Efficiency charts were in watts, instead of load, no calculations would be necessary. If I could look at your charts and see that XYZ power supply provided those watts the most efficiently, that would be the power supply I would get.
Maybe you could just provide a second X axis on the chart that included the watts.
Thanks!

I really like the software component possibilities, looks like it needs some tweaking though like with 18a max per rail.As to memory and CPU usage, well that is .Net for you, that footprint problem is here to stay. Thx to MS.
I'm a little curious to the max 25a per rail.
Nvidia states 8800 GTX should have 30a http://nvidia.custhelp.com/cgi-bin/nvidia.cfg/php/...">Link
Maybe someone can clarify the real draw of an 8800 GTX and is 25a completely sufficient.
What about next gen?
Good review, looking forward to more like it.
As cool as this PSU is, $200+ is a bit too much for a PSU.

Depends on how much your graphics card needs to work. When your display just has 1024pxl in width you can run the 8800 in a decent system with a 300w psu. If you are using a 30" screen with 2560pxl in width it is a total different story. But don't worry, we are working on an article to make things like that very clear.
