Hi, I've recently purchased the Radeon 4870 graphics card and I need a power supply that can support it. The minimum requirements for the graphics card are 500W and two PCI-E 6-pin connections (the one I have now is 450W with 4 peripheral connections). I'm thinking of purchasing the Corsair 750TX, which is 750W. I've read on other forums that the Corsair 550W is enough for this setup, but it seems like for $20 more I can get an extra 200W in case of future upgrades. Also, my motherboard is MSI K8N Neo4 Platinum and processor is AMD Athlon 64 FX -- which to my knowledge is still fine for this system. To sum it up, my final setup would look like: Motherboard: MSI K8N Neo4 Platinum Processor: AMD Athlon 64 FX - 2.61 GHz Graphics: ATI Radeon 4870 1gb PSU: Corsair 750TX Since I'm a newbie, I just wanted to run this by others to see if there's any outstanding issues. Thanks!
Hi, everythin on your setup is fine, your motherboard has one PCI-Express x16 slot for the Radeon 4870 and your 750W PSU is more than efficent enough to power your setup. By the way don't downgrade to the 500W PSU.
What one needs to know about...the relation of the negative effects of heat on the computer...That can be caused by the power supply. Manufacturers test their PSU's at a set temperature...from this their rating is determined... for most this No. is 25 degrees Celsius...which falls short of the temperature that most computers are capable of achieving. Given that a PSU will actually lose 2-5 watts per one degree of heat above the 25 Degree Celsius testing temperature...coupled with the fact that computers tend to run at 10 degrees higher than room temperature... In the summer time when the room temperature can easily reach 80 degrees F... your computer will be running at 33 Degrees C. or 90 Degrees F. So the...math can make...your 500 watt power supply into a 460 watt unit. In addition to this...what needs to be taken into account is that each degree that your computer components are operating at...under powered...adds more heat to the equation. Consider also...the possibility...that ratings given by the manufacturer of single components...such as graphics cards...need to be treated with skepticism...Manufacturers may minimize support issues and under rate the power required...in order to make a larger profit. The above has not taken into account...the issue of high quality vs poor quality units...Power supplies convert voltages from wall outlets to lower levels used by the PC. During this conversion, some power is lost as heat. The efficiency level of the PSU determines how much extra power must be put into the power supply to run the PC. A high quality PSU can help reduce the noise and heat generated within a computer system. The higher the efficiency rating the less heat the PSU has to deal with. Therefore heat is the computers enemy...The hotter the temperature your PSU is forced to run at...the poorer the supply of power the rest of the components will receive...which has been known to lead to such things as crashes, freezing, rebooting, BSOD’s, and video distortion, as well as partial and complete failure of other components. The fact is very few PSU’s are capable of producing the wattage that the companies advertise.

Well...I am glad that pleases you...enjoy...I was familiar with that article. While it too is informative...I am more comfortable with the other one. When I research something I wish to learn about...I do not rely on just one source. Sorry if you find that offensive.
:good: i usually only need Wiki what! me, offended, never, just thought the edited gif was bl00dy funny[ot]Donkey slaps the back of Net Jockey's legs for not thinking the pic was funny[/ot]
I'm re-visiting this topic to confirm that the setup works fine. I've been using it for about a month now with no problems. Rock on! :good:
