I'm currently using a stock 350w psu. I have an msi g41m-p34 motherboard, pentium d 945 processor, and a geforce 9500gt gpu.

I just ordered a new gpu, the geforce gts 250. It requires a minimum 450w. What budget psu can I get? I'm not exactly sure at what all I should be looking for when buying a psu, any help would be appreciated. Thanks!

As I've stated in my post above:

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.
For a system using a single GeForce GTS 250 graphics card NVIDIA specifies a minimum of a 450 Watt or greater power supply that has a combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

What is the make and model of your current power supply unit?

What is your power supply budget?
 
@delluser1's suggestion is also one I would recommend.

The Corsair Builder Series CX430 V2 (CMPSU-430CXV2), with its combined +12 Volt continuous current rating of 28 Amps and with one (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with a single GeForce GTS 250.

$44.99 ($24.99 after mail-in rebate card)

PowerMan IP-P350AJ2-0 is my current power supply, obviously not powerful enough to run the gts 250. What's this 6 pin connector you guys are talking about? like what does the connector look like, and where does it connect? directly to the gpu? and isnt that corsair underpowered?

Distinguished

Amps x Volts = Wattage.

Manufacturers can lie to you so getting a quality PSU from a quality manufacturer is critical. The Corsair can power the 250 because it requires 28 Amps, which the Corsair delivers. Don't listen to wattage. It's just BS. Amps is what matters.

I would recommend you get this Rosewill 430w because it provides more amps than the Corsair at the same price.
 

We're not around all of the time, sorry.

The CX430 is a known good quality psu that exceeds the 24 amp reccomendation for the GTS250
