PSU to EVGA GeForce 960

[Fibercon]

My GPU has an 8 pin with an adapter to two 6 pins. My PSU has a 6 pin and two 4 pins. My PC has trouble turning on when the graphics card is in my PC. The card requires a PSU of only 400 but mine is 450. I don't really know what to do at this point.

Upgrade your PSU. I "think" 4 pin delivers 40 watts, but I'm not 100% sure on that. Can anyone back me up? 6 pin is 75 watts and 8 pin is 150 watts. The PCIe x16 slot is another 75 watts.

There are no 4 pin adapters. Those are for the CPU and there should be a 4 or 8 pin CPU power socket on the motherboard that either one or both of those should be plugged into. They are not PCI power for graphics cards.

If your PSU only has a single 6 pin, then you need a different power supply that has the necessary cabling. Any PSU that doesn't have at least one 8 pin or 6+2 pin connector probably isn't fit to be used with that card anyhow. I'd get a good 500-550w Tier 1 or 2 unit that DOES have the necessary PCI cabling as outlined at the following link:

DarkBreeze, there are no 4 pin adapters "anymore". There definitely used to be. The 4 pin molex connectors were designed to connect to components. The PSU is probably very old. But I agree that the power supply needs to be upgraded.

Four pin Molex adapters are still on every power supply sold. There are no 4 pin "PCI" adapters though, is what I meant. There are 4+4 pin CPU ATX 12v connectors as well, which is what I thought he was referring to.
