I just went through 2 crappy PoWork 650watt PSU's on my gtx 470 running the Witcher 2. I'm on a bit of a budget since I only work part time and I ordered me a http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Raidmax 630w PSU^, I am just curious to know if that will actually pull the weight of my graphics card without exploding. I know it's good enough but and I don't wanna hear that I should've spent a hundred dollars on a corsair. I really don't have that kind of money and I'm just looking to make sure that it won't blow up my motherboard.
For a system using a single GeForce GTX 470 graphics card NVIDIA specifies a minimum of a 550 Watt or greater power supply that has a maximum combined +12 Volt continuous current rating of 38 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.
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 you are trying to achieve.
You may find power supplies on the market that supply more than enough Wattage to run the system. However, some of them lack Sufficient Amperage capacity on the critical +12 Volt rail, which is necessary to properly power the critical components in the system (i.e. CPU and GPUs). This is the reason why graphics card manufacturers may overstate the power supply wattage, usually by at least 50 Watts, in an attempt to take into account some of those power supplies that have the weaker +12 Volt rail(s).
The Raidmax Hybrid 2 Series 630W (RX-630SS), with its maximum combined +12 Volt continuous current rating of 36 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is insufficient to power your system configuration with a single GeForce GTX 470 graphics card.
Raidmax does not specify the maximum combined +12 Volt continuous current rating for the RX-630SS but it is based on the Andyson Advancement Model B Series 600W (AD-5620N2-36) which has a specified maximum combined +12 Volt continuous current rating of 36 Amps.
Raidmax has also earned a reputation in the past for exploding power supplies. I don't think their reputation has improved much.
What about the Corsair cx600w? I ordered that and other people said it was good. Will it power my GTX470 with no overclocking. All i have hooked up is a hard drive and a 2.8ghz processor.
The Corsair Builder Series CX600 ( SKU# 75-001668 / CP-9020048 ), with its maximum combined +12 Volt continuous current rating of 46 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 470 graphics card.
