Hi guys, a while ago I put together a computer and once I realised my budget wouldn't stretch far enough, i had to cut back. Basically I have an i7 3820 in an x79 system with a gtx650 graphics card :ouch:

considering I have a 500w power supply and not many case fans or hard drives or anything, what would be the best graphics card I could use without swapping my power supply?

looking between AMD and nvidia, it seems AMD cards are a little more power hungry, and nvidia cards are more efficient but not as impressive for the price.

also, seems legit, its what i'm looking into :lol:

If you have a quality, 500 W continuous PSU any single GPU card will run on it.

Don't know whats in your zip file; I am at work, hardly.
 
sorry, not very good with attaching images. Its a listing on amazon, a gtx680 for £70, but if you look closer at the image its really a gt630 :lol:

Looks like it might be worth upgrading my power supply after all then.
Mine says it can run as low as 80% efficiency, 400w, which is below the recommended TDP for most powerful cards. I've changed a power supply before in work experience, but that was 4 years ago, and since i've paid for this one i'm afraid of mucking it up :scared:

Not much has changed with swapping a power supply from 4 years ago.
 
My 500 watt PSU can handle 6 case fans, an i5 3570k, 3 hard drives, and SSD, a pump, a fan controller and a GTX 660 (non ti). According to core temp, my system only draws just over 100 watts from the wall when the GPU and CPU are stressed to 100%, but I heard this can be innaccurate.
 
Hi again guys.
After a good look, I have found out a gtx 680 would work fine on my 500w power supply, whereas an AMD radeon 7970 will not.
However, for a total cost of £40 more I could have a corsair 750w modular psu and a AMD 7970 ghz edition graphics card, which would be more powerful and also more futureproof.
So it's really going to come down whether I'm up to changing the power supply and how lazy I am :lol:
This could take some thinking about:boggled:
