Hi!
So, I'm looking to upgrade a "backup" computer made by Acer. Here are the specs:
i5 3330
GT 630 2GB <---- Going to upgrade to 750 non-ti !!!
6GB RAM, 1TB HDD 7200 RPM
300w PSU... supposedly.
Now, for my question. Because this is a prebuilt PC with a stock generic PS, should I upgrade when I get the GPU? I'm trying to spend as little money as possible. Usually, when I build PCs, I obviously use name brands like Corsair, XFX, etc.... but I honestly don't know what the labels mean xD. So, can someone explain to me what this label says and is it safe running an i5 3330 with a 750?

FSP GROUP INC.
MODEL NO. FSP300-60THA(1)
AC INPUT: 100-127/220-240V~,7/3.5A, 60/50Hz
DC OUTPUT; 300W (3.3v & +5V=130W Max)
+3.3V ----- 20.0A(ORG), +5V ----- 26.0A(RED), +12V1 ----- 8.0A(YEL)
+12V2 ----- 14.0A(YEL/BLACK), +5Vsb ----- 2.0A(PURP), -12V ----- 0.8A(BLUE)

Any help is appreciated :D

Thanks for the response Blackbird (You've answered about 3 of my questions btw :3)
So, from what I've established, the CPU and GPU each use a different 12v rail. The first on my PSU is 8A and the other is 14A. The 750 needs 18A on the 12V rail. So... that means I can't run it unless I upgrade?
Can you please help clarify this? Oh, and do you think I can run an AMD 7750.

Thanks for all your help... again :D
