Your 430W PSU 12V max load is 384W. After read all GTX 460 reviews, yes a superclocked GTX 460 will draw around 25W by overclocked 100MHz from default 675MHz and if it can reach 875MHz with 200Mhz overclocked then it will need 50W. I read some GTX 460 1GB reviews with test setups with overclocked Core i7 920 4GHz and i 7 975 3.75GHz power consumption at full load consumed around 300W in gaming and 350W when stressed GPU to 100% in Furmark. So with your E6600 CPU at full load in gaming probably will use around 225W power.

thanks man, very much appreciate the info.

Try running FurMark for an hour - if you've got no freezes, reboots, slowdowns, etc. then stay with your current power supply, there's no need to listen to anyone's advice.

Does'nt a mother board draw any power.

Yes a motherboard is included as system's idle and full load power consumption. My PC idle is 100W and then I removed the idle power consumption of 40W memory, 10W CPU, 15W GPU, 10W hard drive, 10W DVDRW drive and 10W X-Fi sound card. That worked out 5W for the motherboard power.

I would be really very uncomfortable to run Furmark, it not good idea to run it for 1 hour because it can cause damage to videocard's VRM after 1 hour. I searched internet about this and people are told not to dare run furmark for 1 hour.

Sorry, but this is the most stupid thing I've ever heard.

Under no circumstances an application which uses publicly available programming interfaces should damage your hardware and if it does, then your hardware is 100% faulty (except some very corner cases which are not relevant for this discussion, i.e. you can easily kill your HDD by making it start-stop every second for prolonged periods of time).

Any graphics card should sustain running Furmark during entire its lifetime in 7x24 mode, i.e. if you have a three years warranty for your GTX480, that means it's safe to assume that this GPU must tolerate running Furmark for three years in a non-stop mode.

Sorry I have to disagree with you. Try tell that to EVGA and they will disagree with you too, they cant let their EVGA OC Scanner burn for 24/7, it only can allow to burn up to a maximum of 2 hours for safety reason.

I don't care about EVGA opinion, really. They are wrong.

When I had issues with a GT 220 from Zotac They actually told me to run it over night. So I did and it stayed at stable at 65°C and did not lock up the system. So running it longer than an hour should not be a problem unless there is a hardware issue which is what you are looking for when you run this test. Run it for an Hour or 2 and if it is stable then you should be fine, if it is not and locks up then replace the Power supply.

If you have a 430watt and it has 32amps on the 12 rail you should be fine,with GTX 460.

thanks guys, Im still waiting for my local store to get the card..............
