Will this work in a dell optiplex 755? I'm planning to get graphics cards and I need a better PSU

It works well if the this CPU fits into the case. This CPU very reliable, quiet also remains cool under load.

I have one of these, and yes it will work fine. On my other PC, I have a GTX750Ti- same or slightly better performance, but new GPU needs much less power and so no 6-pin power connector- and, it runs 10 degrees C cooler. Also cheaper!

I would not worry about using this card with Dell's 220W power supply in a stock 660s system. The Radeon 6450 is rated to draw just 27W at peak load; this version which uses DDR3 and a passive cooler is likely to draw even less. Both the Geforce GT 620 (30W) and Radeon 7570 (>40W) are tested and supported by Dell for use in your machine, which you can confirm in your owner's manual.

Yes just make sure the PC has a powerful enough psu to run it. I have it running in a small form factor dell optiplex 755 with no problems.

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

It all depends on the 750watt PSU you have. If you have a gold rated high performance name brand PSU it will probably handle it. You will need 4 PCI-E video card power connectors. (6 prong connectors for video cards). You will be pushing a 750w PSU to the max under 100% utilization. If you're just playing games or doing graphics/CAD work and you have a top notch 750 PSU you are probably okay. If you're bit mining and running full throttle 24/7 go for the 1000w PSU. A good indication is, what's the brand and rating of your PSU and does it have four pci-e power connectors. Do not try to use adapters to create more Pci-e power connectors - they fail under full load. It all depends on the 750watt PSU you have.

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/pdthat 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...

Yes...very good graphics card...I do a lot of CAD and it works fine. If the EVGA 500w is a power supply, I would bump up to more like 750, no, I'd make it a 1000W.

This EVGA GT 610 has a PCI-Express 2.0 x16 connector. If I remember correctly, your Optiplex 745 has one PCI-Express x16 slot, so this video card should work for you. NOTE: you can only hook up one DVI-D monitor (Dual link, which supports Dell's 30" monitor in the max resolution). The other DVI port can only go up to 1080P.

I don't have experience with the Dell Optiplex 755. Manual for this PC has table of the compatible ram.

yes it will work just fine if it works the one I got was DOA and they would not exchange it just refund it. I ended up getting a Coolermaster from Best Buy since i did not want to wait for it to be shipped again. I got a 750 watt PSU and hooked it up to a GTX 260 and works great so this should be more than enough to run your card.

It looks like the Optiplex 745 motherboard uses DDR2 ram, the likes of which DDR3 is not compatible. So no, this ram will not work in your computer, you need DDR2 ram.

I can't say for your specific motherboard, but this card is working for me in a Dell Optiplex 755 that shipped on 06/02/2008 (so my MB, model number 0GM819, is 4 years 4 months old, and I believe it's PCI-E 1.0). I think the chances are good it will work for you.Red/.

I have my whole system hooked up to a 750 watt PSU except for my second card, which is hooked up to my 500 watt PSU. So if you're putting both cards on the 750 watt PSU then you should be fine.

I have one of these and the graphics card I use requires PCI Express 3.0 so I guess the answer's yes. It's a VisionTek Radeon HD 7750 SFF (Mfr#900549) which I chose because Dell recommended it. You can go to Dell.com and see what they suggest to get an idea of what you can add.

That should work fine, as long as you don't have too many other things drawing power from the power supply. I believe the recommendation is for a 750, but that assumes you might have multiple drives, etc.

I used it in a Dell Optiplex 455 SFF - if your system is anything like what I have, you should have no problems - hope this helps..
