My old card only needed one of these cables. but my new 4870 will need two. can i just use a IDE-to-PCI-e power cable? its only got 3 wires out of the 6 though. does this matter?
You okorder /... It takes two 4-pin PSU molex connectors and converts it into 1 6-pin PCIe connector. Make sure your PSU can supply the necessary amps on its +12V rails, and if you got a PSU with multiple +12V rails, you need to make sure you got the load spread out among different rails to avoid overloading one rail.
That potential supply is right for that card... do not hardship approximately it... The 4890 takes much less potential than a 4870 and my previous equipment with a 4870 relatively purely used 330W with dissimilar 120mm case followers a 92mm and an 80mm... in case you have already got that PSU then save it....
