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?
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.
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 getting the corsair since everyone is telling me to. even if it seems like it wont have enough wattage.
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.
