i bought a new pc 2 months ago and i was using gt 210 now iam looking forward to upgrade my gpu to hd 7770, that can run bf3, farcry 3, sleeping dogs,gta iv,hitman absolution i want to play all these game at high graphic setting at resolution 1280*1024 and i think hd 7770 can run it, but iam confused if my psu can handle it.....
here is my spec:
intel i3 3220(3rd generation)
dh61bf chipset (3rd gen)
2gb ddr3 ram(800mhz)
360gb wd hard drive
460watt psu(image given in the link below
http://en.file-upload.net/download-9049088/IMG_20140611_210639.jpg.html
my question is, is this power supply capable of running hd 7770 even at max performance if the answer is no, then please recommend another gpu for me that suits my psu, but i have heard nice users reviews about this gpu, i cant upgrade my psu because it comes with casing when i was buying new pc and is in 3years warranty,
so is this psu enough to handle a hd 7770 card?
thnxxxxxx in advance :)

460W is plenty for HD7770. This GPU draws near about 80-100W. So you are covered here. However, as the pic is not being opened at my site the quality of the PSU can't be confirmed at this moment. Would you be kind enough to mention the PSU model here so that it can be checked.

It has system requirement of a "Minimum of a 450 Watt power supply". So your power supply "rated" at 460 watts is just enough. I would recommend a 500-600 watt power supply.

Yes you should be ok with a 7770 in there as long as the PSU is of decent quality. I have a heavily OC'd 4670k with 8gb ram and a gtx780 and while benching my battery backup shows I'm only pulling about 400+ watts from the wall (have a 860w PSU). While your PSU should be ok I would really invest in upgrading your system memory too, 2GB system memory is pretty barebones and you will want more to have a better gaming/computer experience.

For others, I managed to open the Pic. It's a 460W "Legend HS Tech", PSU, no 80 plus certification visible. I tried a quick google search but couldn't find any reviews.

The biggest issue you have is that it's only rated for 22A on the 12V rail (total of 264W), which means it really should be advertised at around a 260-280W PSU.

If the PSU delivers its rated wattage than you're just about okay with a 7770, but it's cutting it fine. Furthermore, you've got no guarantee that it will provide its rated power, or indeed that it won't catastrophically fail (and potentially take other components with it) if it can't.

These are always judgement calls about the level of risk you're willing to take. For me, running anything other than a 750TI on that PSU would be too risky. I expect some on this site wouldn't even recommend running anything on that PSU unless you can find out the manufactorer or a bit more information.

If you really can't upgrade the PSU (which would be your best bet), I'd get a GTX 750TI, something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814487025

See the Original Post, he did. Or at least I could open it fine.

FYI:
- 28A @ 3.3V
- 26A @ 5V
- 22A @ 12V
(Dubiously!) Claims a combined power of 460W.
