GPU for my PSU

Solution
Right on the PSU's label:

+12VP & +12VA & +12VD TOTAL POWER 340W MAX.

Using Ohm's Law: 340Watts ÷ 12Volts = 28.3Amps

No need to guess.

Delta Electronics is one of the best PSU designers and manufacturers.
That PSU has a maximum combined +12 Volt continuous current rating of 28 Amps.

It can handle a GeForce GTX 750 Ti with no problem.

If the PSU has a 6-pin PCI-E power connector then you should be able to use an R7 260X.

The GeForce GTX 750 Ti is the card that has better performance.
 
theoricaly it seems to be able to handle the GTX 750ti, with two 12v rails that gives around 300w, you will still have more than 200W for the rest of your computer to use. So unless you have an AMD FX xxxx you will be able to run the GTX 750ti.

And your PSU can handle even an R7 260x, unless it does not have the required connectors (1x 6pin pcie power cable)

But there is always the question of your power supply quality, but this can affect any card you chose or any component you currently have.
 


Its great to know that my PSU can handle R7 260X as it is cheaper than GTX 750 ti.
But i heard that R7 260X performs better.
If you can provide some proof or benchmarks that`d be great.
 


I didnt know Delta Electronics was that good.
Good to know though.
Thank you for your time.
 
in therms of gaming performance they have similar performance, in some games the GTX 750 ti is better, in other games the r7 260x is better. Only the r7 265 is better than the GTX 750 ti in terms of performance, but the nvidia card have lower power consumption than any of those AMD cards.
