DELL XPS and Radeon HD 5770

If you have the 425W psu, you should be able to run it without a new psu.

In fact, you might well be able to run it with the 375W psu, if that's what you have.

You have a BTX motherboard, its a custom design for Dell. If you decide to buy a new psu,let's make sure its not a custom psu as well.

A better power supply in ANY Dell system is a good upgrade, the video card with the correct power needs should work just fine...

What are the exact specs of your PC? Dell typically understates the power rating of the PSU by an amp or two (that's a good thing). If I remember correctly, Dell farms outs their PSUs to Fortron Source Group who has a reputation for making solid and affordable PSUs.

First off, lol, malmetal we have the same pic XD..... I just contacted Dell and they told me that I can't get a new PSU cause I would have to replace my components within the computer. So I'm just going to get the Radeon HD 5670. How can I run the HD 5770 if the card says that I need a 450W PSU??

Also forgot to mention, I have a PCIE 2.0 slot, can i use a PCIE 2.1 card??

They are full of it.
Your stock psu, wether the 375 or 425, can handle a 5770, how? because manufacturers overrate the wattage needs to make up for the lack of amperage on generic power supplies. The Dell power supplies can provide most of thier power to the 12v rail.

thank you for your answers, if i were to go with the Geforce 9600GT, will the low power version affect the life of the card of the performance? also I see that some cards require a PCI-E 2.1, and mine is a PCI-E 2.0, will I be able to use a PCI-E 2.1 card? And I don't know what you mean by C2D or C2Q, I'm a beginner at this XD

I meant "or" performace

i got a Core 2 Quad Q9450 2.66 GHZ, 3 GB of ram, and just to let you know, I have a 425W PSU

Even when i contacted Dell, they told me it's a Dell xps 420 (must be an upgraded version), currently got windows 7. what PSU should I get, I just might get a 700W PSU, not sure of what brand and how much does it cost, and for video card, I might just stick with the Radeon HD 5770, but what brand is good to get? Also, I'm thinking of getting more Ram later, I think the max ram is 8, so once my computer slows down, i get more ram, lol

700 w psu, if a quality brand is over kill.

a 5770 is a good buy as it is on the edge of dx11 runnability at 1600x1200 ish levels

with a 425 w psu, i'd say, get the gfx first (even if you need the molex adaptors it may still work) if it complains get the psu second

although, if you do want to upgrade your psu and everything in one go, maybe the gtx 460 1 gb (not the lesser 700 mb one) would be a better fit, or even a 5850 if you want to stretch budget

what do yo game on? if it was 1920*1200 then i would say all of this talk is moot point and if you are on 1280*1024 then any and all of the above is over kill and an older ati or nvidia card may be better suited

my screen resolution is 1680X1050, currently I'm trying some MMORPG games, the games that I have for some time are NFS prostreet and Crysis. What do you mean on the edge for DX11 at 1600X1200. I let you know what I choose, I'm still deciding, just want to make sure everything is perfect  . Actually i have 4 GB of ram, but since i have 32-bit WIN 7, it reads as 3 GB of ram

Are you letting the fact that the OP has 3 gigs of ram lead you to believe that it's DDR3 ?

my ram is DDR2, it would be nice if it was DDR3  

fyi no a regular atx psu will not perfectly fit into a xps case... but 2/4 skrews will line up so i've replanced em with standard atx psu's that way just warning people it'll work but make sure if they move it ever to make sure the two are in tight.. alternativly you can take out the mobo and everything and drill in the holes in the proper location for all 4 to line up

Will it fit perfectly ? No, there will be a gap because the Dell psu is 10mm taller than standard, but there's no need to drill any holes, all 4 psu mounting screws line up just fine

must depend on the case, i was working on a xps case where i had to redrill 2 holes they were off by just a bit to get it in there right, the system i was workign with was an xps with a intel core duo i'd have to ask fo rthe model but i couldn't get it to line up correctly without a little dremeling  

I hope it fits it perfectly without making any holes, also was it easy to put the new PSU into your DELL computer?

Something's going wrong here - the OP has a 425W psu and does not need a different psu to run that 5770. Why are we going down this path?

He's got a purpose-designed BTX mobo, and I wouldn't touch that psu unless/until I had to.

because we tend to over spec things and new things = shiny = pleasing?

anyways seriously try a 5770, at 1600 you should be fine with it for some time, if not dx11+aa+af all the way for new games at least dx10 or dx9 codepath

that is a drop in upgrade, so hell maybe try it out from a local frys or something and see
