Dell Dimension C521 upgrade

This question is not answered

I was wanting to upgrade my Dell Dimension C521 computer.

I was wondering what type of socket the 521 has. Would this AMD processor work? (AMD Athlon 64 X2 5600+

Windsor 2.8GHz Socket AM2 89W Dual-Core Processor Model ADA5600CZBOX - Retail )

I was also wondering if the PCI Express(X16) slot was version one or two.
Would this video card work?
(SAPPHIRE 100253HDMI Radeon HD 4650 512MB 128-bit GDDR2 PCI Express 2.0 x16 HDCP Ready CrossFire Supported

Low Profile Video)

Thank you for your time and any info you can provide.

    The Athlon 64 X2 5600+ Windsor 2.8GHz Socket AM2 89W Dual-Core Processor, should be fine, prior to installing, update the BIOS to the latest version.

    The SAPPHIRE 100253HDMI Radeon HD 4650 512MB 128-bit GDDR2 PCI Express will work, but requires a 400w power supply.

  • I'm in the process of doing the same thing. Through my research I found the following thread on the Forum pages http://www.techsupportforum.com/hardware-support/motherboards-bios-cpu/354366-cpu-upgrade-recommendations-dell-2.html it was very usefull. On my particular model of C521 I found out that I had to reuse the same origonal Heat Sync that came with my computer, so I had to go out and get some Arctic Silver 5 from Radio Shack to install my AMD Athlon 64 X2 5600+. As the previous poster said your PSU unit is only rated at 280. I found a Vidio Card on Dell's web site that is supposed to be compatable according to Dell. I have ordered it and it's supposed to arrive this coming Monday.  it is XFX GeForce 9500 GT http://accessories.us.dell.com/sna/products/Gaming_Video_Cards/productdetail.aspx?c=us&l=en&s=dhs&cs=29&sku=A2418163. The PSU requirement was @ 300 if I'm not mistaken. This is based on running XP. I do not know if it is Vista compatable.

  • clewlessinflushing,

    As for the video card, there have been many discussions on video cards and required PSUs on this and many other forums. 

     

    The manufactors overstate the recommended PSU wattage required and  Dell understates the power of their PSUs.

    Just for another opinion check at this site for reviews from 4 Dell owners with 250w PSUs, 1 Dell owner with 275w PSU, 1 “other Brand” with 280w PSU, all said it ran great with no problems.

    I purchased the same Sapphire HD 4650 low profile and have been using it on my stock 250w PSU with no problems at all, I am not a heavy gamer so do not stress the card.

    According to ATI recommended PSU of 400w it is risky to get a HD4650 if you have a lower watt PSU. It will depend on the individual computer and what has been added to it and what the user wants it to do, heavy gaming or other heavy video use then maybe no.

    Check out this article on The Truth About Graphics Power Requirements See how many watts you really need.

    The best thing to do would be to keep the safety margin. Best way to ensure no problems in the future.

    Regards,

    Dave
