Not sure how to choose what power supply I should get for my system. The specs are listed below if anyone can either find one for me and send me the link or tell me how I can figure it out on my own, I will appreciate...Thanks P.S. Don't want to spend anymore than $150 on a power supply

Motherboard: MSI P45 Neo3

Processor: Intel Core 2 Duo E8400 3GHz Wolfdale

RAM: Corsair 2x2GB DDR2 800

Graphics Card: Nvidia GeForce 9400 GT PCI-E 2.0 (1GB DDR2)

Hard Drive: WD Caviar Green 1 TB (300 MBps)

CD/DVD: LG RW & Media 48x/16x

Operating System: Windows 7 (64-bit)

I ran the number with adding 3 120mm fans totaled out at 250watts. I would suggest you buy a 400w for some scalability.

Unless you plan in the future to upgrade the 400...

Unless you plan in the future to upgrade the 400 is fine. if you plan on upgrading mainly cpu and gpu i would go 650 and 850 for SLI.

Corsair makes quality power supply as does seasonic. i have a corsair currently and never had an issue with them in the past so yes i'm slightly bias.

This will work perfectly for your current setup.

For a system using a single GeForce 9400 GT graphics card NVIDIA specifies a minimum of a 300 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 18 Amps or greater.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The Seasonic G-360 (SSR-360GP Active PFC F3) power supply unit, with its maximum combined +12 Volt continuous current rating of 30 Amps and with one (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce 9400 GT graphics card.
