Dell underrates thier PSU's, I believe they are rated to sustained output, whereas others are rated as peak.

6800gt is power hungry, id be rather carefu. richpls might be right, check max output on your PSU label...

I have a the same card and the requirements are a 300w psu as stated above, but also 22amp 12vrail min.When I first got the card I had a 20amp 12vrail and it ran fine no hiccups.A few months ago I picked up a Ultr X Connect 500w psu 34amp 12vrail, because I planned on over clocking the whole system.

22 amps?!?

Are you talking SLI?, 'cause there's no way a single card is gonna draw 22 amps.

oh crap you know that dell makes crappy products so the psu could give out at aany minute oh wait rdram nevermind that pc was built when dell actually made good parts but just to be safe get a new psu with 300 wattage in that vicinity

I ran a 6800gt agp on a light as a matchbox 400w psu (shite free with a case job) for a while with no probs, but then after a while hdd's started switching off etc, so ended up upgrading after a while anyway

I'll keep you guys posted but its still huming along fine, maybe it helps that I do not have many other stuff pulling from the PSU.

By the sounds of it this should be my last Dell

I know for a fact the BFG 6800GS OC AGP draws 18A, because I have it. I wouldn't be surprised if a single 7800GTX 512MB can draw 22A.

Anyways, you can try to run it on that PSU, but I wouldn't recommend it. It might run for awhile, and then burn out. If I were you I'd get a safer, more stable PSU (you can get a good PSU for as low as $40) and stay on the safe side rather than risk frying your video card.

Those BFG lifetime warranties sure can come in handy though, can't they?

If it's running fine then good for you. But with less power your graphics card settings would automatically sets to low. But if your not getting a message that your graphics card needs more power, then you're fine. Buying a 350 watt psu would only set you back $25-$30.

I wouldnt do it go out and buy a $50 450w Power Supply.

Them Dell 250 W PSU's are quality, very solid. A friend of mine runs a 7800GT with an X-Fi Platinum and reports no problems after 4 months or so.

Yeh I ran a 9800xt on a dell 250w psu for a year, its still working now as my brother has it.
The 9800 prob has the same power needs as a 6800.

Dell do under rate there psu's, go to the dell oforums there will be loads of people running a 6800 on a 250w.

6800gt needs FAR more power than a 9800.

With PSU's being as good and cheap as they are today, theirs no reason not to get a good one somewhere in the range of 450 W minimum to 600 W max.

The wattage rating is primarily bullshit. A 500w shitbox isn't worth half as much as a 350w high quality brand-name PSU. Stability for a PSU matters more than pure power in a rig.

The 6800gt and 9800xt both have a min of 300w psu, how can there power requirements be much different. A 6800ultra would be pushing it but not a gt.

A dell 250w psu if rated as max output like the rest of the market is 345w, more than enough for a 6800gt.

As I saif there are plenty of people running the 6800gt on a dell 250w on the dell forums.

6800ultra's are just overclocked gt's with extra power. Exact same core/chip needs, just slightly higher vcore.
Minimum requirements don't mean jack. Why do you think the high end 6800's are notoriously hot?
