X1900XT on P5WD2-E PREMIUM HELP PLEASE

post #1 of 12
Thread Starter 
Has anyone gotten their X1900XT to work on the ASUS P5WD2-E Premium motherboard?

Mine will power up but nothing will show on the monitors.

Thanks in advance for your replies.

I know this is probably going to sound funny but did you plug in the PCI-E power connector in the back?

Chim3ra,

Thanks for the reply.

Yes, I plugged the 2x3 plug into the back of the card.

I have a Antec NeoHE 550 PSU.

I'm currently running a BFG NVidia 9800 GTOC 256MB card in the PCI-E slot that I want to have the ATI one in.

Any ideas?

Since when you have that Antec NeoHE550W?

I'm asking because I had that PSU and it ended up being the single source as to why my system never powered up.

NeoHE and ASUS boards are not a good combo.

And BTW, that's the last time I buy an Antec PSU for my future rigs, my 430w was faulty, my current SP2.0 500W couldn't power my 650 @ 4.2ghz and the NeoHE550 ended up being a 3 and strike out, no more Antec's for me.

Nasgul makes a great point. Reading through the reviews on newegg, a lot of ASUS owners have been complaining about these PSUs. Their complaints stem from something about the 5v rail.

That Card specifically needs 30A on the 12VDC rail to operate. Maybe the problem is that each of the three rails is 18A max. I somehow doubt it. More likely the PSU Asus issue posted above.

Hi guys,

The PSU has worked great on my other machine and similarly well on the machine in question. In addition, ATI actually picks that PSU as it's recommended Crossfire PSU:

http://www.ati.com/technology/crossf...crossfire.html

Click on the X1900 link.

With the power spec does that mean 30A on 1 rail or on them all together? My understanding is that it's for all of them together. That's why that PSU should have enough juice for 2 of those cards.

Also, is there anyway to know that the card IS actually getting enough power?

The fan spins up, is that a sign? Also, where the 2x3 plug connects it turns red for a sec when the comp first turns on.

In addition, the BFG Nvidia 7800 GTOC is working great with that PSU.

If there was a clear way to determine it is the PSU I would gladly get something else. However, it seems that ATI themself recommend it.

Thanks to all of you for the responses. Any way to tell that it is actually the PSU or further suggestions?

Did you just buy the card?
Maybe it is a DOA.

It has happened before to other people.

I bought the card a few weeks ago from newegg. I returned it for replacement as ASUS said it sounded like the card was bad. Got the new card and it did the same exact thing.

These are new cards out of new boxes (vacuum sealed). The chances of both cards being DOA is slim.

From the looks of it I'll be going to BestBuy or Fry's tomorrow to get a new PSU. I just wish there was a way to know for sure that that was the culprit.

Though I guess it's the only thing that makes sense.

Gonna look at what's available ... suggestions for a new PSU would be greatly appreciated.

Also, what's the real meaning of amps on the 12v rail? Is it per single rail or all combined?
