Dell Inspiron 620 - Graphics Card Upgrade

Jump to solution

Hey,

I currently own a Dell Inspiron 620 desktop, with a 300 Watt power supply, and AMD HD Radeon 6450 as my graphics card. I am thinking about upgrading my graphics card, but I want to avoid upgrading my power supply unit as well. Can anyone suggest some good graphics cards that a 300 Watt power supply would work on? I know its low, but I don't have enough budget to upgrade the PSU as well. Games I play include NFS Hot Pursuit, COD: MW2, L4D2, Portal 2. (I'm thinking about getting MW3 and BF3)

Other Specs:

2nd Gen Intel Core i5

6GB RAM

Also, are all graphics card the same in size, or are they different. I would also like to know the size of the video card required for my Inspiron 620, too if anyone knows.

Thanks for reading.

You need single slot cards.  Radeon HD6670 works fine and is about the max you can do. For the TOWER version of the 620.

Some Double Slot cards will be (TOO LONG) to fit in the case and will REQUIRE a non stock 650W power supply.

Agoraptor,

I'm not a gamer myself, but  the Nvidia 9800GT gets pretty good reviews.

Unfortunately, the minimum power supply recommended for the 9800GT is 400 watts.  It would work in your 620 if it's the mini-tower version and you upgraded the power supply.

All graphics cards are not the same size.  If your 620 is the mini-tower version, you shouldn't have any problems installing the 9800GT if you upgrade the power supply to 400+ watts.

Information on the 9800GT can be found here:  www.nvidia.com/.../product_geforce_9800gt_us.html

Note that the 9800GT requires two 6-pin supplementary power connectors as do many high-end graphics cards.  Be sure your replacement power supply has these.  Some of the 400+ power supply only have one 6-pin supplementary power connector, requiring the use of a power adapter for the second one.  I recently ran into this problem on a client's graphics card upgrade for his gaming system.

Hope this information helps.

Actually 2 Slot wide Versions of the 9800GT will not FIT into the 620 without Upgrading the power supply.  There are versions of the 9800GT that are

ENERGY Efficient that work.  Aka 9800 GT EE version.   I have used these as well.   There is a 2 slot version from Zotac or the PNY VCG98GTEE1XPB.

Speedstep,

Agreed!  Two-slot versions such as the Gigabyte 9800GT which has that huge Zalman heat sink would not be recommended.  The Nvidia 9800GT to which I made reference  is a single slot card.   The Zotac card which you referenced was the card I installed in my client's custom-built full tower system.

I have no issues with the Zotac card that I got.  Its an uneasy feeling hacking off the bracket to shoehorn one into a GX620.

I'm confused! You said that the Radeon HD 6670 works fine, it says here that the minimum power requirement is 400w.

www.amd.com/.../amd-radeon-hd-6670-overview.aspx

I have the tower version, and I want to try to avoid upgrading my PSU.

Thanks

The power requirements are overstated.

K, but what about the sizes? I'm not sure which size I should get, and which size graphics card is mine (AMD HD Radeon 6450)

Single slot cards only. Some Double wide ones (Too Long) do not physically fit. Double Wide Cards also need a Bigger Power Supply.

The 6670 5670 4670 all work fine with stock power supply.
