You need to check voltages under load tbh...Your never going to tell otherwise.

Tom|Nbk · 15 May 2007 at 23:09

No wonder it dosnt work you need those Molex all plugged in to get the Full 75W from each 6 pin.

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

Its the only way to be certain. Checking the 12v on the card after the connections under load. It'll tell you if the PSU is drooping to much and/or the connections are dropping voltage as well. Its one of the reasons the use so many commons on the 8 pin, it helps reduce voltage drop with high current.

I had them all plugged in before and it was the same situation.

Its not just the plugs being full, its having enough separate wires/conductors from the PSU. Apart from the resistance problem, too few will make them run warm. Maybe not so you notice, but over time, say they cross a sharp edge it sinks into the insulation...

Thought you had another psu ? you tried using that to run the card and use the internal psu to run the shuttle.

have they just released newer drivers?

Gerard · 15 May 2007 at 23:26

Well same thing happened, system died near the end of the airship test.

Same ones that are currently out.

the owners or the shuttles?

doubt it's the owners

Gerard what is the model # of your Shuttle PSU?

Hello Gerard.

If it helps I'm running 2 1950XTX's in Crossfire on a Shuttle 400W Power Supply, I'm using the 6 pin splitter that came with my SD37P2. Not sure how much power the 1950XTX's take but I guess it's a lot. Rest of the spec is E6700 at 3.4Ghz, 2 Raptor 150's, Water pump, 120mm fans etc. Under extreme 3D load my cards are clocked to 695 the Power Supply fan speeds up but other than that no side effects.

I would hazard a guess the 400W powersupply will handle the 2900XT.

That helps, according to xbit they consume 124.70 at peak 3d load Thats almost 251 watts for 2. :eek:

That psu has one dedicated pci express connector im asuming? How many 4 pin molex's does it have floating around? :confused:

If i could id just bung one of these into it

The contact area would have to smaller than the shim around the GPU as it's raised. I did see a pic of a Dangerden full cover block though...

Arse.. There goes my big selling point.. But still the money I saved by buying it through work will go to buying a waterblock and it'll still probabaly work out cheaper!

Connector wise it has 1 PCIe connector and the Shuttle came with a splitter for it, so it's supplying a fair old bit of juice at the moment.

3 SATA power leads

I think just 2 std molex connectors, but I am using splitters on them for the 120 fans at the moment, the Shuttle came with a splitter type cable for a floppy drive too.

I was amazed when mine booted up when I first built it, but these 400W power supplies seem very strong.

Sounds good, 1 dedicated pcie means only 1 splitter needed. Hate having a load of them laying around.

I think you'll be OK with a 400W, are the motherboard connectors the same?

On mine there is one at the front and one at the back, you can see the front one in the piccy, the other one is hidden under the PS.

EDIT I hope it's OK, I fancy the 2900XTX when they come out.

Yup, the psu does all p chassis layouts, just checked one at the front one at the back.
