No. Dell uses a proprietary power supply. You can find them in the internet for around $30.

It seems Dell uses the same model numbers for different computers over the years, I found this http://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf which is for an older version that would for sure not work with the ram. Or I guess looking at your link no it won't work, this is DDR3 memory, where as yours uses DDR2. But you could try downloading CPU-Z (http://www.cpuid.com/softwares/cpu-z.html), go to the SPD tab after memory, you can at least get what speed of ram you have there and work off that.

As long as the OptiPlex uses PCIe cards this one has a "low profile", meaning that it is NOT thick and should easily fit into any Dell tower. It's really easy to remove your old card and install the new one - very easy.

can't be sure w/o your xpress code or svc tag - just look at the different form factors for optiplex 755 - http://www.dell.com/us/dfb/p/optiplex-755/pd that said - if your optiplex is no more than 2-3 years old - 99% yes, b/c it's PCI express ready and low profile (so should fit in small form factor - the worst case in sense of space for ext. card). given that - if I were you, unless you want to share your xpress code so I can actually check what hardware specs you have, then I'd say go for it - worst case return...

This is a TFX type supply which is a standard form factor for desktop computers. Check the one that comes out of your Optiplex to see if it's TFX as well. If it is, the only question that remains is whether the wires are long enough to reach peripherals etc.

As long as the Optiplex has a low profile PCI-e slot. If this is the Optiplex Micro, then No, it will not work. The Micro is an all-in-one machine. Not much for upgrading on the Micro.

I installed this card on couple Dell OptiPlex 3020 SFF PCs without any issues. It's a decent card to support dual LCDs Panel w/Display Port.

If yours is the mini tower (leftmost in this picture: http://en.community.dell.com/resized-image/__size/550x0/__key/communityserver-discussions-components-files/3514/2806.Opti-745.JPG)...that card will fit fine. In fact, it doesn't have to be a low profile card like that. Any full size card will also fit. The only issue would be length if the room in the case is limited by a drive bay or something else.

I'm not sure if this video card is compatible with an Dell Optiplex DT. We used it for Dell Optiplex 3010. I hope this helps!!

Looks like it would according to dell's website. http://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdfKeep in mind that the OptiPlex can have a max of 8GB of ram. Therefore, if you were wanting to max the installed ram you're better off buying 4 2GB modules rather than buying 1GB modules for all models except for the Ultra small form factor. The ultra small factor uses 2 4GB modules.

I've purchased one of these for an Optiplex 745 Small Form Factor and the front plastic panel on the drives cd tray fitted too tight in the PC'c opening, therefore the drive was unable to open. As far as the drivers windows 7 pro will install it automatically as long as you connected to the internet.

David, you should see in your mother board dell optiplex, and check the model

Nancy, according to the Dell website this model optiplex 745 is already equipped with the Core 2 Duo but hard to tell which series- Possible upgrade to that would be the core 2 Quad.

Call up Dell's product specs on this board...it may work OK, but I am not privy to this info

My son's computer is a Dell Inspiron 5315, which is what I bought it for. But the Dell site does say it should work with the Optiplex 745. One thing you might want to think about, when I took this memory to Best Buy to have it installed (I have a service contract with them so that was a free service), they told me I could have also bought the 4 GB kit (2GBx2) to max out the memory. This 4 GB set was also available here on Amazon for about five bucks more if I remember correctly. Hope this helps.

I can't give you the full thing of specs but here is the link to a .PDF with the full specs http://i.dell.com/sites/content/business/solutions/engineering-docs/en/Documents/optiplex-780-tech-guide.pdf

Dell in the past has used a proprietary power supply that is incompatible with industry-standard ATX, but dropped this practice some years ago -- several sources says 2001, another says 2007ish. The "tech specs" document for the 745 is © 2005, so it's probably OK, but you can easily check yours to be sure. Wikipedia has an excellent article about this (under "ATX") with one section ("Issues with Dell power supplies") describing how to determine if your Dell computer is or is not compatible.
