View Full Version : PSU: 20 to 24 Pin Adapters

My Enermax PSU has a native 20 pin plug and I had been using a 24 pin adapter with no problem in the past. The PSU has a 36A 12v rail. Thing is the adapter may be causing too much resistance because the readings are way too low underload.

Anywho I am not using SLi until my new PSU arrives. I was posting this as a warning, especially if you are using SLi. I'd say skip the adapters and just get the proper PSU, particularly when going from 20 pin to 24 on a PCI-e mobo. Check your voltages underload if you are indeed using one of these adapters.

You're reading your voltages from software, aren't you? Your PSU is fine, since you are using a PC P&C PSU.

Use a multimeter to see if your unit is feeding your system the proper voltages.

Sorry about that. My old PSU I am speaking about is an Enermax. The PC P&C SLi will be replacing it, and I am sure it will be fine. It is native 24 pin. I updated my sig and the new PSU should be around in a few days. For now I removed one 7800 GT from my rig.

For some reason DFI warns folks very vocally about using 20 to 24 pin adapters on their PCI-e mobos. I think what I am doing is best even if I might get by with the Enermax. It isn't worth it to risk all this gear.

I've been using an adapter and all is well even with SLI(12v is about 11.71v under full load with both cards). But you're correct; one should not play around with power, especially with expensive hardware. I think you made the right decision:)
