Enermax Revolution 85+ SLI or Crossfire certified, but not both.

Finally these powers supllies are starting to make it into retail (end of next week for the UK, where I am). But according to the Enermax website you have to pick a supply depending on if you are going to run Crossfire or SLI. That's how I read it anyway.

See 'http://www.enermaxusa.com/cata...h=21_60&page=1&sort=2a'

Once you have decided on the wattage you want, say 950w, you then have to pick a model that is either ati or nvidia certifies. Either the -00 or -01 model....

That seems a bit rubbish to me. Now I have not brought a power supply for a while, and this maybe standard nowadays that a PSU cannot be both SLI and Crossfire certified. Enermax extol how much the the revolution85+ is ready for anything the future may hold, that is unless you change between Nvidia and ATI graphics cards.... Yeah, great furture proofing.

These are going to be quite expensive power supplies, so I would expect them to be relavent for a few PC upgrades.

Anyway maybe someone on the Ananatech staff, after give the PSU such a glowing review and recommeding it as part of the XMAS buyers guide (even though it was not avliable before XMAS), can ask Enermax to explain this further. What is the difference between the -00 and -01 models, if any? And if no difference why the two models per wattage class.

This is going to cause great problems in buying these, since all the retaillers I have seen selling these at the moment, don't tell you if it is the Crossfire or SLI certifies supply they are selling.
 
How exactly does this matter? You know there's nothing inside the power supply that says "Oh noes, ATi cards! I can't do this!"
 
I believe the nVidia SLI certification requires the PCI-e connectors to be on separate 12v rails from the rest, so that may be the difference - even though the spec sheets for both say they 12v are split the same

Who knows maybe you will get more crashes etc.

It must matter some how, else why make two models. It must cost them more to have two models for each wattage than one, different packaging, etc.
 
No.....as far as I know nVidia will not certify a unit that is ATI certified and probably vice versa...so in order to have the unit certified by both, they just give the same PSU two different SKU numbers...otherwise they are 100% the same.

Really silly, but there it is. Kind of like how both ATI and NVIDIA used to lock their multi-GPU abilities to their chipsets.

I don't think ATI ever locked thiers to a chipset... intel made the chipset... nvidia just refused to allow thier's on a competting chipset until the x58 came out and they were caught with thier pants down without something to compete.

edit.... except for the AMD cpu platform ... :roll:
