I thank you in advance for answers:)
 
Isnt the psu the box where the power cable goes into? If that is the psu there are two "model numbers" on the side of it: ac 520 rd+ and atx 520w switching power supply. I apoligize for not really making sense but i have never upgraded a computer before :)
 
I'd probably replace that at the first opportunity.

Most off-brand ones have both horrible build quality, don't adhere to specifications and have low efficiency. It would pay for itself over time to get a decent PSU.
 
Yes the one on amazon looks like mine. Thanks for the help! I looked for the GTX 750 TI and it costs the same as the one i was going to buy. Well if you recomend it ill buy it then :) But what is the difference between the two?
