Hello everyone. I will be running 2 GTX 550 Ti in near future. So what I want to know is which SMPS and how many watts of SMPS will be able to run my pc stabily? My Config. Intel Core 2 Duo E4600 @ 2.4 Ghz (Sood Upgrading to Core i7 Processor) Intel DG31PR (Motherboard) (Sood Upgrading) 2 X 1 GB DDR2 RAM (I'll be upgrading it to 16 GB with my Motherboard) 3 X 320 GB WD HDD
More aboutneed smps running
For a system using two GeForce GTX 550 Ti graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 500 Watt or greater power supply that has a combined +12 Volt continuous current rating of 38 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.
Get a 650W smps to be on the safer side...
If you are planning to do a lot of gaming and not high end video editing, then i would suggest you to go for an i5 2500K and pair it with a good Z68 mobo.
