I got used Fujitsu Siemens ESPRIMO P5720 that got PSU with max 230 w

It is a BTX case ( i didnt know that when i purchase it , lol ) so I think it would be hard job to change PSU .

Model of PSU BTX NTS-230EB B

Max continuous DC output power is 230 W
max combined +3.3V and +5V continuous DC output power is 100 W
AC INPUT I--------------------I DC INPUT
100-127V /8A I-------------- I +3.3V 7.5A
200-240V / 4A I-------------- I +5V 15A
50-60Hz I-------------------- I +12V 17A

AC OUTPUT I---------------- I AUX DC OUTPUT
100-127 /3A I-------------- I +5V 2.0A MAX
200-240 /1.5A

I intend for this comp to use it as a temporarly online gaming rig for Dota 2 , LoL , HoN ,and later on to use it for old games that can be played only on Win XP , in 1024 x 768 , full details and AA , so I hope not to burn out comp, my wories are this low input of +3.3V and +5V , and not to mention BTX Instalation of GPU , the went goes up , not down , i got wories in that area too, so can i put radeon 7750 here or not.

all other components using 71W / 102W as it says here in this data sheet: and here they say like " optional GPU for P5720 ; NVIDIA Quadro NVS 290 256MB,GeForce FX 7300LE 256MB,GeForce 8400 256 MB, how much they draw power ?I think this GeForce 8400 draw a lot, so can i buy then Radeon 6570 or stronger ?

Dude gpu pulls power from +12v nota 3 or 5v.you have 17A so 17 *12= 204w output.so hd 6570 will work as its tdp of 43w.
