20 to 24-pin PSU Converters, anyone using them?

[grss1982]

Recently bought this from a local store here in Cebu. I was just wondering if there are any problems using this thing.

I would not think there are any problems with these converters. The only real issue that I can think of is that with this converter is keeping the ATX cable nice and tidy in the case. I am talking about keeping good airflow by keeping cables neat and hiding them away in corners and unused areas of the case so that the air can circulate better. This may be difficult with the converter since effectively the cable is longer than usual.

The only problem I can think of is if you have an older ATX PSU that doesn't put out much amperage on the 12v rail, with most on the 5v. Most of the newer systems power the CPU from the 12v rail, so you might be overloading an older unit.

As long as there is enough wattage for the system and no clearence issues(like a coil or capacitor in the way) a 20 may be used on a 24 pin board or a 24 may be plugged into a 20 pin board without any adapter. The extra 4 pins will just hang off the end of the port.

What about those motherboards that have the extra "ATX12V" 4-pin power connector? (which consists of two ground wires and two 12V wires)

Can you power those with a supply that doesn't have the ATX12V connector?

I've got a lot of ATX power supplies that do not have the ATX12V connector. I think they make adapters to convert a disk drive power connector to ATX12V for the motherboard, do these work?

I have an Enermax 431W DUal Fan PSU. Using the converter its only going to be powering this system:

ECS RS400-A
Intel Pentium 4 3.0Ghz HT
2 x 512MB PC533
Nvidia 6600 LE
IDE HDD

Yes they do make those adapters and they do work,you just have to make sure that your psu can handle the extra 12v load.And yes you must use the atx 12v connector because that powers the cpu vrm.

The ATX12V connector is connected through the board to the 12v on the 20/24 pin anyway.
The only reason for it is to use more wires to get the 12v to the board.
By using more wires they can pass more amps without overloading the wires.

They could do the same thing using larger wires but larger wires are harder to twist around to plug things in.

Most PSU's use AWG 18 gauge wire.
18 gauge wire is rated for something like 6 amps per wire.

May not be true on all boards. Has been on any I bothered to check.
