Can i install Palit xpertvision geforce gt 730?

Check the specs: http://www.palit.com/palit/vgapro.php?id=2767&lang=en&pn=NE5T7300HD46-2081F&tab=sp

It has graphics power of 25w.

The PCIe x16 video card must be low profile/no fan =
Nvidia GT 730
AMD Radeon HD2400XT/HD3450/HD4650/HD5450/HD6450

I have a 275w psu but on 1 post i seen people telling that gt 730 is working normaly.

Here is the link to post: http://www.tomshardware.co.uk/answers/id-2387193/optiplex-755-zotac-geforce-730.html

So i wanted to know if this is true and if you could sugest me a gpu that could play games from 2000 like half life 2, minecraft, team fortress 2 and so on because on intergrated gpu it realy lags.

Check your PSU. It looks like Palit needs a 300w PSU. You most likely only have the 275w or 280w PSU.

The GT 730 is too wide.  The 2ND card does fit and works fine.  The 3rd card would need the bracket to be modified or removed.

Even on Desktop models the space is very very very limited both length and thickness.  So a HUGE passive heatsink wont allow the card to go inside the slot that is ONLY 1 card wide.

SHORT AND NARROW SLOT

This guy dremeled out parts of the case and hard drive mounting on DESKTOP model just to fit a card.

Newer low profile thin cards like ASUS EAH6450 fit because the heatsink is flat and thin.

Sorry for a silly question but what is a bracket?

And i wanted to get this card: Dell Amd Radeon HD 7570 because it is in my local shop.

And does this card work in Dell Optiplex 755 sff?

For NON TOWER 4C5DK  Low Profile  Radeon HD 7570 GDDR5 works.

The full size bracket would have to be Cut and bent or removed altogether.

This card comes with BOTH Brackets.

LOW PROFILE VS FULL SIZE

Can i buy a bracket that matches size of my pc?

Not likely to be easily found.

Retail Cards Like the ASUS EAH6450 come with or without both brackets.

If you get full size you can bend the full size bracket and cut the excess off with tin snips.

Is any of these gpu's capable of running games like minecraft, half life 2, team fortress 2?
