Upgrade Old Dell XPS 420

I have a 2.5 year old Dell XPS 420 desktop...it either has a 375W or 425W PSU and a 8800 GT video card. I want to replace the card with something like a 5850/6850/460. I'm not sure if the PSU is adequate or if the cards would even fit in the case/motherboard.

Anyone have a clue?

Thanks.
 
what are the rest of the specs of that computer and what res do you want to play at? and please take a few seconds and see what psu that you actually have instead of just guessing.
 
You should stick with a card that is close to, or under, what the 8800GT requires in power. So the HD6850 is your safest option, as it generally needs less power than a GTX 460 and 5850.
 
I don't have the computer with me...I am in the process of moving and it is being shipped currently so I can't check out the specs until it arrives. It does have a quad-core 6600 and just a regular 8800 GT with 4 GB of RAM and Windows 7.

Someone on another forum said they upgraded their XPS 420 with this http://www.newegg.com/Product/Produc...82E16817139005 and it worked well, so I will probably get this one.

Seems like most people are recommending the 6850 rather than the 5850 or 460...so that is what I will probably buy after I confirm that the PSU works properly.

Get this PSU instead of that one.

if that is a 425 watt psu in then there will be no need to upgrade the psu. what res will you be playing at???
 
Someone on another board said the XPS 420 requires six SATA connections on the PSU, and from what I could find online, the PSU you recommended only has five. I have no idea what any of that means, but the person was pretty insistent that it needs six.
You better look at the computer for yourself. Don't always rely on what other people say, especially if you have the hardware on hand and you can check it out in person. I'm not sure why you would need six SATA power connectors. I mean, it's possible, but it doesn't seem probable.

Probably 1900x1200. I can already play games like Mass Effect 2 at that resolution on full detail with my current setup, but I want to be able to play newer games as well.

well a stock Q6600 will limit you from getting the full use of a high end card in a some cases so don't expect to be able to get the same numbers you see in gpu reviews. at 1920x1200 I would go with a 6850 and keep your current psu if it is a 425 watt unit.
 
well depending on his res any suitable gpu will be fine with that 425 watt psu. these 375watt and 425watt psus were good beefy continuous power units.
Yeah? So? If he upgrades to a new PSU, which should have other benefits such as higher efficiency, then he won't have to worry. I'm not saying he needs to, at all. An HD 6850 should work perfectly fine without a power supply upgrade. Really any of the cards he mentioned should work, but the 6850 would be the safest option since it uses the least power.

and it would make no sense to upgrade the psu if he doesn't need to is all I am saying.
 
Do you even know what you write?

I do. His system came with a 375 watts psu (8800gt came with the 375 watt) and a older 65nm quadcore cpu.

I think a 2.5 year old psu, a older quad core cpu, with a 155 watt (peak) card is pushing it.

Edit: after some more research it has a combined 12volt rail of 30 amps . 18amps + 18amps but only 30 combined or 360 watts.

I'd recommend a gtx460 1gb or 6850, whatever is cheaper and you will NOT need a psu.

Unless the PSU he uses is a quality brand, i still believe he should get a new one, after all, it is 2.5 years old and PSU efficiency decreases with time. At 500W, he'd be perfectly fine for this and even future upgrades.

with a stock Q6600 any future upgrade beyond a 6850 or gtx460 would have minuscule results compared to the jump from an 8800gt to one of those cards. those psus that Dell used back then where very strong and underrated. thats why they used them in their XPS line that could be configured with quads and top of the line gpus.
 
You'd probably do fine with a 6850 with that psu, but this Seasonic is one of the highest rated around and is not expensive and will offer you good stable, clean power for that card, and you could buy an even more powerful card like the 6870 (or 560 when they come out).

One issue you are likely going to run in to though is screw/hole placing on the back of the unit to affix the psu, if this is your case here:

A standard ATX PSU should fit fine in the case, but you are going to perhaps run into an issue with only 2, or 3, screws fitting. It should still be secure though.

If upgrading your psu is too much of a bother, then a 6850 would do fine as mentioned since it is a XPS series PSU (just so long it is the 425 watter). A 460 would be out of the question because I doubt that PSU has 2 pcie connectors, and though you could use an adapter it wouldn't be worth the bother.

LOL this right here is why you don't know what you're talking about.

http://www.gpureview.com/show_cards.php?card1=544&card2=636
8800GT: 105W TDP
HD6850: 127W TDP

http://www.techpowerup.com/reviews/HIS/Radeon_HD_6850/26.html
HD6850 Peak: 109W (on the high side compared to other reviews)
HD6850 Max: 129W

http://www.xbitlabs.com/articles/video/display/radeon-hd6870-hd6850_9.html#sect0
HD6850 Peak: 90W

So please don't pull some bologna 155W number out of your butt. The GTX 460 is the only card (mentioned here) that comes close to that.

So I ask again? Do you know what you write? You did expand on it after I probed you, but your initial post is just worthless. You say nothing of any value, using an undefined pronoun "it" in a declarative statement. I mean, let's look at that post again...

A Dell xps 420 with a 6850? I think thats pushing it.

How in the world would you think to write this and only this? ARE WE SUPPOSED TO READ YOU MIND?! Be clear; that post could mean several different things. There are two good reasons why you would simply make that post. One reason involves me insulting you, so I'll cut that one out. The other reason is that perhaps you were just looking to push buttons. You can't honestly think posting that and only that is enough to make your point without posting why you think that or even, gasp, what the hell you're actually saying.


So I ask again, did you know what you wrote, and why you wrote it? Well the answer is clearly NO, as you receded your earlier comments with this:
Edit: after some more research it has a combined 12volt rail of 30 amps . 18amps + 18amps but only 30 combined or 360 watts.

This is really funny. And not in the "ha ha" kind of way - in The Watchmen's The Comedian "it's all a joke" kind of way.

My old machine was a XPS 420, I swapped the old card for a 5770 and it ran like a top in that system. Computer has since been moved to a closet as the emergency back-up for the new rig below.
