Dell optiplex 755 mt graphics card upgrade
Hi all!:)
I have an optiplex 755 minitower. I have a EN8600 gt graphics card, i want to buy http://www.asus.com/Graphics_Cards/R72501GD5/ this. Will it fit in the box? I know that the best choice is 7750 low profile, but in my country is not available. Sorry for my english when i wrote something incorrect. Thank you for your reply :)

Ok so I ended up buying the Diamond HD Radeon 1 gb low profile card for my Dell Optiplex 755 MiniTower, well right off the bat I knew there was gonna be problems, First the big black case is really tight against the card and because of the two "transistors" right above the video card slot the radeon hd7750 would not fit. So I removed the fan from the top of the video card and it went in but when I started up the computer, black screen. Ok so next I made sure I had uninstalled the drivers from my previous ATI Radeon X600 series and yes they were gone I also made sure that in my BIOS that video card was s elected and when that didn't work I went back to "auto". Still didnt work, the monitor doesn't say no signal it just remains black. I tried installing the drivers before I put the video card in and that didnt work, I tried putting the card in and removing the cmos battery to see if it would work and NO it didnt work either I am thoroughly frustrated and this was my birthday present and I was very excited to receive it now really pissed! I know I should of dealt with Tigerdirect!! I bought the video card from DiamondMultiMedia on eBay they had a 99% positive rating so I was like ok good deal lets roll. After all this I called support and the tech talked to me like I was a fifth grader to which I informed him that I had tried everything. He wanted to give me another card but I have to pay the shkpping to send back this Radeon HD7750 and then they will send me the other Video Card lmao I said no way I want my money put back on my card!!!!! Dont buy this http://www.diamondmm.com/7750pe51glp-diamond-amd-radeon-hd7750-low-profile-video-graphics-card.html it wont work in the Dell OLptiplex 755 MT

A full sized card will not work because the black fan case and the transistors are all in the way!!!!

Thats why you get Sapphire or ASUS because they fit.
Problem with THICK cards is that they don't physically fit in the Case.
This guy documented this problem very well.

So for those still looking for the 7750 low profile I think its this card now.
http://www.newegg.com/Product/Product.aspx?Item=N82E16814129294
All low profile sizes of ×4 and ×8 PCI Express cards are allowed a maximum power consumption of 25 W. All ×1 cards are 10 W
Towers with 305w power supplies allow up to 75w for the X16 slot on bigger power supplies
http://www.intel.com/support/motherboards/desktop/sb/CS-012073.htm
Optional connectors add 75 W (6-pin) and/or 150 W (8-pin) power for up to 300 W total Video power.
Cards that need more power have Molex power tap for X1 slots.
Only Fits in MT MINI TOWER
Also you have to watch out for Double slot versions

The R7 250 is not that far behind the performance of the HD 7750 anyway. You do not need a low profile card in the Mini Tower. A full size card like the Asus you linked will fit fine. If you want something with much better performance, the new Nvidia GTX 750 would work also if available in your country. All three have the same power consumption. However, the 755 is an older system with a slower CPU so I would probably stay with the R7 250 and not go too high or spend too much. It's still much better than the old 8600 GT.

Thank you for your answer. I will stick to the asus R7 250 then. It is enough for older games in HD :)
