I'm adding

My current setup;

Core i5-2310 2.9ghz
Standard Insprion 0GDG8Y motherboard
2x4gb ddr3
1x SATA HDD
1x PCI Ethernet
2x cooling fans (1 cpu, 1 case)

Looking to change out my current GPU (Radeon hd 6450) for an Nvidia GTX 660 2gb, which is basically a quantum leap.

Thermaltake's system calculator says i'll need around 375w and recommends a 430 w PSU. I'm thinking just going for the 500w to give a little breathing room.

Also thinking of adding another case fan for additional cooling.

Thoughts?

Get a 600W for future-proofing.

Another case fan is always a good idea.

500w is plenty the 6450 is not a high power gpu. Just don't get a cheap unit no matter what size it could still fry the system or cause instability. Here's a guide for choosing a make and model of power supply, get something in tier 1,2 or 3.

500 is good enough, if it's a brand name PSU like Corsair, Seasonic, Antec. If it's some garage sale special one, than it prob doesn't have the amps on the 12V rail needed, or the pins.
