okay didnt think i had to mention this but the minimum requirement for the video card is 500w with a 12v/36amp which niether of the ones linked are.
Here are the system requirements for the GTX260GeForce GTX 260
Thermal and Power Specs:
Maximum GPU Temperature (in C) 105 C
Maximum Graphics Card Power (W) 182 W
Minimum Recommended System Power (W) 500 W
Supplementary Power Connectors 6-pin x2
The recommended PSU is for the entire system and I'm pretty sure that a 500W can handle the entire rig because few years ago I ran my rig with a GTX260 OC and don't had any problem.
This are two good options for u:
1- Corsair 550W
2- Antec 550W
I prefer this for the Bronze Certified but is sold out.
