Do I need a new PS for the GTX 260?

[Indus]

My rig in its entirity:
Core 2 Duo E6550 @ 2.93 ghz (7 x 419) CPU
4 x 1GB G. Skill PC 6400 DDR 2 SDRAM @ 419/ 838 Mhz
Gigabyte P35-DS3L Motherboard
BFG GTX 260 OC @ 675 core, 2304 memory
1 D-Link NIC
1 Western Digital HD
1 Lite On DVD-RW Drive IDE
Logitech G15 Keyboard
Logitech G13 Speedpad
Logitech MX518 Mouse
Samsung 225 BW @ 1680 x 1050 resolution

All powered with an Enermax Noisetaker II 485W powersupply. ( http://images10.newegg.com/NeweggImage/productimage/17-194-009-05.JPG )

Now I've had this system for 2 years and its been awesome, no hiccups. Then last month I started playing Aion and I was getting lagging/ stutter for the first time in a while so I went ahead and upgraded from an 8800GT to a GTX 260. This has made it a lot better but I still get the occasional stutter in raids but not so everywhere.

Is it possible it can be attributed to power supply not having enough power when it needs to draw more charecters and effects? I mean I don't have any random reboots or anything but still occasional stutter.

I was thinking my PSU might be at its limit but it is holding well enough for the rig but I maybe wrong. Do you think the 44 Amps provided by the PS is enough for the GTX 260?

Or is this a power supply problem? What do you think?

Weak power supplies don't make video cards stutter. They get blamed for that a lot, but if your PSU's output wasn't enough for your system, then you'd get crashes, lockups and reboots like you said.

The PSU looks like it's sufficient for your rig.

When I went from an X1900XT to my current 4850 and tried to keep my 450W Antec PSU, 3d apps would work and my system remained completely stable, but my framerates suffered greatly. I hadn't realized that could even happen until I saw it with my own eyes. Once I got a new PSU, the 4850 started performing normally. I never had any lockups/crashing/rebooting with the weak PSU, though - just low framerates.

That being said, the OP's problem doesn't seem to be the same as what I experienced (the 4850 + weak PSU was performing worse than my X1900 was). Maybe you're just slightly CPU limited at times in Aion? I'm afraid I don't have any firsthand experience with that game, so I'm just guessing.
