Gigabyte's New Odin GT 800W Power Supply

Cables and Connectors
On the front of the power supply are the jacks for the detachable cables. This is the first modular power supply we've looked at, so we are certainly interested in seeing whether there are any drawbacks to such a design, as has been suggested by other manufacturers in the past. There are four sockets located in the middle that can be used for the Molex/SATA component cables. The jacks on the right are for the two PEG graphics card connectors which come with 6/8 pins. On the left side are jacks for an adjustable fan and four temperature sensors. There are four temperature diodes included, two of which are 50cm and the other two are 70cm in length. Another cable that can be used for a 3-pin fan - for use with the already mentioned port - is also included.
All the cables come in a good quality bag, similar to what we have seen from other high-end manufacturers. The cables are all sleeved, even after the first connector. This is special because it costs quite a bit more to sleeve the cables from end to end, but it results in a more pleasing appearance.
With a minimum length of 50cm and a maximum length of 90cm you can deliver the power to all components even in a large tower chassis. To make comparisons with other power supplies easier we are now using this standard graphic that lists all of the most common lengths. The connectors at the SATA-cables are angled and the last one of the two cables is straight. The ATX connector is very stiff which doesn't allow the cable to move much once connected to the mainboard. If the cable is bent or pulled it could potentially damage the jack on the mainboard.

Does the software need to be running for the voltage regulation to work? Or can you make changes then close the software and have the changes still work on the PSU?Also I'd guess if UV lighting is that useful for a case you could swap the blue LEDs for some UV ones - looks like enough wire is exposed to cut the blue ones and solder in UV ones.

Hello,nice review (i wouldn't expect anything else of you). But I've got a question about the measuring-software: Was it reliable, when measuring voltages? You already mentioned, that the wattage was not reliable. So I'd like to know, if that was because of wrong measured amps or volts.
greets Oberst.

Voltages have been quite accurate; amps have been wrong in almost every case.qpwoei - Tuesday, July 24, 2007 - link
Once you've got the ripple measurements sorted out, it'd be nice to get some scope traces as the load changes. Poor transient response of the rails can cause all sorts of hard-to-diagnose problems in the real world.Christoph Katzer - Tuesday, July 24, 2007 - link
We use a scope to follow response on the rails but until now we feel the data is not good enough to present. If there would be something to extraordinary to tell we surely would.bob4432 - Tuesday, July 24, 2007 - link
what about that? a good quality unit, the Corsair 520HX seems to be a lot of people's favorite lately, how does it really stack up? or some of the FSP "Green" units - are they really that efficient? what about seasonic - really as good as everyone says?these reports are all fine and dandy, but you are catering to possibly 5% of your user base, yes even here 800W is extreme overkill.
and it is not a $$$ issue but rather a reality issue. i am surprised you guys testing these are continuing the thought process by only reviewing the upper wattage units and thus making everyone think they need one when they don't - people on review 750W psus, so i must need one...come on guys

Will come. No worries about that. At the moment we are just starting as you can see and of course every company wants to have the best PSU tested first. We'll have lower ones very soon but need to work on that mountain of PSUs here first. With 380w you will see a Seasonic pretty soon for example.bob4432 - Tuesday, July 24, 2007 - link
will definitely be looking forward to them :)ATWindsor - Tuesday, July 24, 2007 - link
I disagree that an OCP per rail i s a good thing, it onyl makes using the PSU more of a hassle, since you can draw a lot less from the PSU on 12V than the specs would make possible, if you are unlucky and draw most of it from one rail. Several manufacturers have one big rail without any know safety-problems, having an OCP for the combined drav from the 12V-lines however is a good thing.AtW

I would be interested in knowing how a psu runs with dual 8800gtxs in virginia in summertime in an old house with a window air conditioner.Not these theoretical white glove clean room lab environment tests.
triple sli 8800gtx?
come one stop playing with your iphone.
