GX520 Motherboard Upgrade

Hi,
 
i would like to upgrade the motherboard on my Optiplex GX520 to accomodate a PCI-e graphics Card.
 
I can get a hold of a GX620 motherboard which i believe would be a direct swap?  any idea what the part number is for a GX620 mobo just so i know i'm getting the right one - its for a mini-tower
 
is there anything else i would need to change?
 
is there a guide to changing a btx motherboard online anywhere?  i have never swapped a mobo before so don't really know what i'm doing but have been told it can be done in ten minutes.
 
any idea how this would effect my warranty?
 
Cheers,
 
G.

The part number is F8098. Service manual: support.dell.com, enter service tag, choose Manuals, Service Manual, removing and replacing parts. Yes, it will void your warranty to replace the system board.

Thanks,
 
do you know if i can upgrade the PSU? 
 
i was thinking of something in the range of 400 watt to get a half decent graphics card.
 
Would i need just any 24 pin PSU or does it need to be a Dell?

Yes, a standard BTX-connector PSU will work fine.

Probably you don't need upgrade your PSU.

thanks,

bearing in mind it is a 220watt PSU in the GX520 do you still stand by this statement?  or would the 305w be needed?  i see your test shows only 200w drawn but would extra not be needed to allow a tolerance for peaks?

Hi ZooHornRollo,
 
Generally speaking, you can push DELL's power supplies. They are undermarked!
Based on my tests 200.8W was the "highest" consumed (peak) with all devices FULL LOAD (Graphics Card, Processor, 2 x HD, 2 x DVD and Network Card).
If you decide to go, don't forget to share your results later at this Forum.
 
Best Regards, :smileywink:
