XPS 420 and ATI RADEON HD 5770 Questions

Hello, I have DELL XPS 420 and I'm want to upgrade my video card. 

I bought this computer last year here are the specs : 

Core 2 Quad E6600 2,4 GHZ

4 GB RAM 

ATI RADEON 4650 HD

Will ATI RADEON HD 5770 fit in to DELL XPS 420? 

If so, will the stock power supply 450w (On label it says DC output 450w so i guess that's it.) be able to work fully with this card and specs above?

How do i change the card? I'm confused about those blue "rails" or whatever they are is there a way to take them off?

Thank you for quick answer.

I did not realize the XPS 420 came with a 450W power supply.  The XPS 420 came with a 375W power supply and if you got the 8800 GTX video card they put in the 425W power supply.  Most likely you have the 375W.  The instructions for installing and removing the PCI Express video card can be found HERE. You should still be able to easily run the HD 5770 on the 375 watt PSU as others have run the HD 4870 on the power supply which uses a lot more power.

  • Dell Optiplex GX280, P4 3.2 GHZ, 80GB SATA HD, Windows XP 32-bit
  • Dell Inspiron 530, Q6600 Quad, 500GB HD, Vista Home Premium 32-bit

Thank you, and sorry my mistake I have 425w checked it now... but I have HD 4650 strange.

Doesn't that card need a reserve? Will the PC be able to handle it even on maximum power usage? 

On the cards website there was a recommended power supply 500w.

I don't want to mess something up so I'm just asking.

If you look at this chart here, you have more than enough power since you are only looking at 272 watts for the entire system under load load with the HD 5770.  The manufacturers always overstate what is actually needed.

Re: XPS 420 and ATI RADEON HD 5770 Questions

just one fast question before I order the card. 

Does XPS 420 Motherboard has PCIe x16 2.0 slot or 1.1??

Not sure, but more than likely it is 1.1.  However, it will still run fine and really not effect the performance of the card much.

I just installed an XFX 5770 in my stock XPS 420 (375 PSU), no issues at all and a nice performance gain from my old 8800GT.  Used the new 9.12 Catalyst drivers.

My System:

XPS 420

Windows 7 64bit

Re: XPS 420 and ATI RADEON HD 5770 Questions

Thanks so much guys, I googled something like "will a dell 425W power supply work with a video card recommending 450W" and up pops this thread, with people already installing the very Radeon HD5770 I have on order on the same XPS420 I have! 

I was *pretty* sure the power supply and size were okay, but great to get confirmation.

Should be installing tomorrow. I really want to run GTA IV on full settings and my old 8800GT just can't handle it.

Also, I did a little checking -- it appears the XPS420 uses the X38 chipset, which means it has PCIE 2.0. 

http://www.lifeatmost.com/pc/dell-xps-420/

http://www.intel.com/Products/Desktop/Chipsets/X38/X38-overview.htm

It's hard to tell if it really matters. The max bandwidth of the 5770 is 73.6 GB/sec, but the 2.0 16-pin PCIE is only 8GB/s.  I'm not sure if this means processor bandwidth is unrelated to the PCIE bandwidth, or the processor is so rarely fully utilized it doesn't matter, or the PCIE bandwidth is bottlenecking the processor (seems unlikely), but it looks like GPU bandwidth always greatly exceeds PCIE bandwidth. 

http://en.wikipedia.org/wiki/PCIE#PCI_Express_2.0

Maybe someone more familiar with these issues can elucidate.
