Gerrard have you tried the drivers on the CD to see if they still have the fan issue.

Tokenbrit · 15 May 2007 at 21:30

I am using CD drivers and they have the fan issue also.

Doubt it

Are you confident 400w will be enough? What wattage does it recommend on the box?

I have a 500w psu albeit a fairly average one and it dies a little way through 3dmark06

What PSU?

DidStock · 15 May 2007 at 22:08

Its a zoostorm 6500HP.

Says it can run 2 cards in SLI

the owners or the shuttles?

It looks like you only have one molex connector plugged into each adapter. Don't you need two molex connectors to supply the necessary 75w for one 6-pin connector? (4 seperate molex connectors are needed to power 2 6-pin adapters).

I love my shuttle but there is no way it will run a 2900XT.

Yeah but theres nowhere near enough molexs on this psu to get the job done, i think theres maybe 2 regular molex connections. If the psu aint up to the task, splitting them off to fill the remaining connection in the pcie splitters wont make any difference.

The box reccomends 750 watt, but that of course is playing it very safe. The card maxes at 200 watts for normal usage and aroud 220 or so for overclocking. That leaves maybe 180 or so for he rest of the system, i don't see 2 sata drives and an optical drive taking up that much power.

The site has the psu advertised as this:

Shuttle SilentX 400w Power Supply to suit all 'P & P2 series' XPCs. This special Shuttle PSU is incredibly efficient and is capable of running two nVidia Geforce 7900GTXs in a SLI configuration so should be thought of as an equivalent to a 600w conventional ATX Power Supply.

Im assuming this will be enough for the card, shuttle don't offer anything higher than a 400 watt so its my only real alternative anway.

It is your only alternative if you choose to stick with shuttle.

Apart from implication of pulling 75W down a single wire. Don't forget the voltage drop on just two conductors. More current means less voltage.

Thats assumes the wattage is all 12v? What is the CPU clocked at?

True, i'll proly be building a new rig later this year when the new intels and amd's hit so we'll se then.

Well the way i have it currently it seems to run anything but 3dmark 05, during the airship graphics test the system will shut down totally. Ive tried filling the molexs's and the same thing happens.

Maybe i should check the splitters incase thers a dodgy wire somewhere.

Do you have a multimeter?

Not at present, bloody battery died and its a really akward size to get a hold of.
