I just ordered a Sapphire X1950 Pro video card and I was wondering if my Dell XPS 400's power supply (375W) would be sufficient for the video card. The video card also comes with a 4-pin Molex to 6-pin auxiliary power cable and I don't know if it will be able to connect to my PSU.

Someone please help

I'd get a new PSU with better ratings on it, that Dell PS is a generic, non gaming PSU, and you might not have enough draw for the card to function like it should. You can just get by, but I wouldn't chance brown outs on the vid, it will destroy it. And if you OC your card, it would not have the load to do it with.

I'm also wondering if you have enough clearance in your case to fit the card. The 1950 is a full size vid card.

You'll be fine with the stock psu, use the 6 pin connector from the psu, marked "P12" and don't worry about the adaptor that comes with the card.

Thanks for the feedback, my video card along with 2*512 ram sticks should be arriving in a day or two. I thought I had to use the cable it came with, but now that you mentioned the "P12" connector it makes sense to me now. As for the card fitting into the case, I checked the measurements and it should be able to fit. Once the vid card comes I'll post back here on how it's running.

You will find that Dell PSUs are excellent and deliver clean amps. Wattage is not always a good indicator, and there is really no such thing as a gaming PSU, only PSU's that can and cannot deliver certain watts and amps. Most high watt PSUs are like that to support a large number of drives, dual processors, quad video cards etc. Your dell case limits you to a reasonable 4 drives, if you want more go e-sata external on external power. You wont run out of watts on your 375 watt unit.

In the future it may be best to ask this question before you buy the video card, however it seems theres no specific additional power requirements specified pertaining to your video card, its news to me that Dell PSUs are excellent and deliver clean amps these days as the former poster stated, its more like just enough power to cover the original machines hardware, so upgrading can be funneled through them, its kinda legally how they make additional money, the machine worked perfectly until the upgrade.

If the card performs flawlessly then I'd say you're lucky, if it starts freezing, locking up, or no reason blue screening, upgrade the power supply quick, so you don't damage anything, hope the best for you! Ryan

I'm not very good with computer hardware so I was unaware of the whole wattage/PSU stuff and I learned about it a day after I placed my order. I also forgot to mention that the video card says it requires atleast a 450W PSU, but I have read posts of people running high-end video cards with Dell's stock 375W PSU.

Its better to be safe than sorry, thats a 75w difference, you'd be better off if you could find the exact amp draw on the 12v rail and target satisfying those requirements.

The Dell 375w psu can provide 30amps on the dual +12v rails, it is used to power the 8800 GTX in thier XPS 410, so the X1950 Pro will be no problem.

dells use power supplies made in bulk by pc p & c, if they are shipping heap of units and say 1 in 10 fails, that is alot more money for dell, they want something reliable.

That's news to me.

The X1950Pro will work fine in the XPS400. I have a X1900AIW that is in my kids XPS400. No Problems at all. The power supply that Dell uses is a good power supply. Its not great by any means, But it will power a 1900XTX.
