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!

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?

Can I get a good one for under 25?

The Logisys PS480D2, with its combined +12 Volt continuous current rating of 16 Amps and with no PCI Express supplementary power connectors, is grossly insufficient to power your system configuration with a single GeForce GTS 250.

@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?

i guess i'm going to go with the coolmax since no one is answering me.

Have fun cleaning the blown up PC then.

Corsair screams quality, not so much of Coolmax.

PowerMan IP-P350AJ2-0 is my current psu. will the corsair power my new gpu? the psu is rated at 430w and the geforce gts 250 requires a minimum of 450

As I've stated in my post above:

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.

"Total Continuous Amperage Available on the +12V Rail(s) is the most important factor"
The CX430 is a known good quality psu that exceeds the 24 amp reccomendation for the GTS250
