Power Supply Lacking Connectors?

[tedferris]

My current power supply apparently doesn't have enough PCI-E connectors for my motherboard (ASUS Crosshair V Formula) and GPU (MSI R9 390). The motherboard needs 8 and 4 (12 total) and the GPU needs 8 and 6 (14 total), but the 3 power supplies I have checked all only come with 24 total connectors. Any ideas?

Youre looking at something wrong. ALL motherboards (and new model PSUs) have a 24 pin connector, there are additional PCIe connectors as well.

What PSU are you working with?

I have tried with a Corsair TX650 650W, a Be Quiet Pure Power 9 500W, and a Cooler Master 550W. All of them don't have enough PCI-E connectors. The motherboard is eATX, though, so that could be where the extra 4-pin connector comes from.

I realize that I didn't really explain this very well, but essentially, the motherboard has 2 connectors along the top in addition to the 24-pin one on the side. The 2 on the top are 8-pin and 4-pin. The graphics card I have has an 8-pin and a 6-pin connector, and I can't seem to find a way to have enough connectors for both. The power supplies all have the 24-pin connector, and then 24 other ones, but I need 26. Any ideas?

Ok so the additional CPU Power connector on that board DOES NOT get a PCIe connector, there is a specific CPU connector that it needs that all 3 of those PSUs should have. has nothing to do with eATX, its because the board is for overclocking. Now the Formula also has an EXTRA 4 pin cpu power connector for extreme overclocking, you can skip that one, and just realize your overclock capability is limited. Generally only 650w or higher PSUs have this extra connector.

BeQuiet's specs show that there is a 4+4 CPU connector on that PSU

The Corsair TX650 is old, it should have it as well but I wouldn't use it due to its age anyway.

The motherboard requires 0 pci-e connectors. The motherboard has 1 24-pin atx, 1 8-pin EPS and 1 4-pin cpu power connector and only the 24-pin and 8-pin are required the 4-pin is for extra power when overclocking. The TX650 has the required 24 pin and 8-pin(4+4) connectors and it also has both the required pci-e power connectors for the 390.

When I used the Be Quiet one, the PC would be unable to boot up. I assumed the issue was with this connector but I went on PCPartPicker and the Be Quiet 500W power supply isn't enough. Of the other 2, I'm leaning towards the Corsair one because it's more powerful, newer, and I trust Corsair more. Would you object to this?

The Corsair should do the job. The BeQuiet is a bit weak for that GPU if you're running something like an FX-9590.

I am 100% sure it has the correct connectors. You need to plug in ones that say EPS to the 8 pin CPU connector, you can ignore the 4 pin.

What cpu are you using? The 390 is a power hungry card and if you are pairing that with a FX 9xxx series then you are going to need a bigger PSU.

I have an AMD FX 8350
