PSU for a Pre-Built PC

[Eliiots]

Hey guys, i'm wondering if there is any good PSU that can fit in Fujitsu ESPRIMO P556 E85+/E95+ for GTX 750 TI as mine may make it work or not and i don't want to risk anything, so is there any PSU will fit this ?

Thanks for the help, also what do you mean by this "Does the motherboard and have all standard ATX PSU connections.

24 pin for the board power and 4 or 8 pin for the CPU power , if so you can change it out.
