Dell Optiplex 745 Mini Tower Graphics Card Help

Okay so i have long been searching these forums without an account, hoping to find an answer to my predicament.

Lately I have been trying to start getting into computer gaming since the games tend to be cheaper, not to mention that buying games through steam is very convenient. However when it comes to my computer, I realize it's graphics card is lacking in quality. In fact, I'm pretty sure it's just integrated graphics that came with the computer.

Anyways I have a 305w PSU, and like I said it's the Dell Optiplex 745 MINI-Tower.

I have found that the, Sapphire Radeon HD6570 , would be perfect for me as it is well priced and relatively powerful for the limitations my computer has.

The only worries I have are:
1.) It (the card) says it has a PCI express 2.0 but my computer has 1.0 so will that stop it from working?
2.) As I said, my power supply is 305w but the product says it requires 400w, will it ruin my computer? Also someone in the reviews said that they had a 270w psu and it worked

Any help is appreciated

Hey !! i was using that PC before ( Optiplex 745 mini Tower ) and i upgraded the Graphic card to HD 7750 since it uses only 55 watt max only and you can fit it inside the case as i did

this is smaller than my model , it will fit perfectly :

i was running battlefield 3 and many decent games using that graphic card + Pentium D 3.4 + 4 GB ram

btw ... if you want to push that pc to the limit , then you have to upgrade the CPU to Core 2 Quad Q6600 as i did ..

I think u don't have to worry too much though.

PCI-E 2.0 card can work on a 1.0 port just like usb 2.0 disk work in usb 1.1 port. (Means this card is capable in working in the pcie 1.0 port, but may be slower by less than 10%)

Such product "requires" high wattage PSU is just laziness of the manufacturer. Of course 400W PSU can support HD 6570, but since this card has only 55w TDP your PSU can support. (PCI-E port can provide up to 75w power support)

So follow the suggestion of this @kareemGT guy and go for a HD 7750 GPU is OK

I would love the hd 7750 but I just don't want to spend that much money since I'm 14 and have no steady income. Anyways i should be good with the hd 6570 even if it isn't that powerful?

I see no problems in terms of power, but if you could squeeze a bit extra for 6670 that would be better.

If you are trying to save money, list your budget, I will take a look what can be done.

Here is little guide on what can actually fit into Optiplex Mini Tower


THIS POST APPLICABLE TO MT (MINI TOWER) FORM FACTOR ONLY.

Unfortunately no card that is more than 7.5 inches long or 2 slots wide will PHYSICALLY FIT inside the case - it was found that only single bracket video card can fit due to BTX MOBO, where card internals facing upward towards PC internals, not ATX, where dual card design is blocking another PCI slot by facing downward.
If you prefer the card with beefier fan, then the length of the card must not exceed 7.5 inches, otherwise only "skinny" single bracket, single slot cards can physically fit.

Pictures below will prove my point.

View shows no room for dual bracket



Single bracket only, or you have to cut dual bracket in half



Here you can clearly see only single place for the bracket



Visual explanation



7.5 inches explained, also shown "obstacles"



This is the picture of actual "skinny" single slot video card (not sure which model)- perfect, "glove" fit.



So, not every card can physically fit. Therefore, please list your budget and which retailer you can use, if you can use online.
