HD 5570 uses 150-200 watts all by itself and the stock power supply in your computer is only 250 watts .
You would need at least a 5-600 watt power supply. While the HD 5570 might be a decent entry level game card it is way overkill for HD video.
For HD Video /HTPC /casual gaming a low powered fan less AMD/ATI based HD6450 1 MB 64 bit pcie 2.1 card will be more than enough for HD video and sound with HDMI output ,they will be quiet and only consume 17-25 watts depending on what it is doing so your internal 250 watt power supply will run it fine and does not require any additional power connectors .
HD 6450 runs fine from the PCIE slot power.PCIE 2.1 is backwards compatible with PCIE2.0 since you have a mini tower a low profile bracket shouldn't be needed but most 6450 cards include them .The HD 6450 is a popular HT video card. they go for $25-$35.00
If your Acer Veriton M275 has the usual Intel E6700 chip that's plenty for HD
and can play some light games .
OTOH if you are a gamer and want to try HD 5570 it is much better at games than a 6450
You could only do that if you also put in a 5-600 watt or more watt power supply then it would work.
but for anything other than games you would see no difference. If you don't plan to game on this box then for sure a 6450 will more than work.
The HD 5570 is probably overkill for the e6700 CPU it would be happier with an i3/i5/i7 CPU
I put a HD6450 in an an HP Slimline 4 core AMD box with a stock 220w power supply it runs fine.
My Sapphire HD6450 1 MB runs a PC monitor and bedroom TV set. it adds independent screen support and as a bonus upscales DVD's very well .It is way better than the on board video was.
it will run the TV and PC monitor in two different windows doing different things at the same time .it can support up to 3 monitors independently but no SLI.
I use a PS3 on the HT set up it has excellent video processing and DVD upscale the 6450 holds it's own with it at..........at least for DVD up scale and movies. BD and gaming are PS3 territory. Nothing like gaming on a 55" plasma unless it's something bigger.
Search You Tube for a video such as "installing a video card in a PC with on board video"
or just "installing a video card in a PC "
it's not hard .
You will have to uninstall your on board video drivers in Device MGR then power down unplug it and install the new card
If you get an AMD/Radeon based HD 6450 or whatever it is recommended to first download the drivers from AMD and use those instead of the CD.
Do that before you install the card just remember where you put them or just install from download folder .install the card first then the drivers .
When you reboot with the new card installed use the f10 or f9 key whichever gets you into the bios then go to settings and disable on board video .
windows will then load VGA mode low res video drivers that's normal
installing the drivers is easy go to control panel/device manager/display device /right click /update drivers /from files this computer/ find the files /open them and let it install.
You can then assign primary and secondary monitor designations /resolutions ( if using two screens ) from the desktop by right clicking then go to set resolution screen the video will be at least 4 times better than the on board Intel GMA chip. You will gain the advantage of 1GB of dedicated video ram also. Your PC will think it took a viagra !
