Works great!

Adapter works perfectly fine (5 stars) however I do have a caution for using this adapter: make sure the PSU you connect to this adapter has over-voltage protection. In one test, I connected a relatively recent 80W HTPC ATX power supply through this adapter to an old Intel 486DX motherboard and it worked perfectly fine. In another test however, the same motherboard and adapter combination caused an old 250W ATX power supply without OVP to overvolt and spew smoke within 1-2 seconds of powering on. PSUs lacking over-voltage protection are designed for recent motherboards and their electrical loads, and they will over-volt when connected to the lighter loads of older 386/486/Pentium motherboards. To put it another way when using this for older systems: don't be cheap with the power supply!

I have some old PC's that are still running 24x7, and the power supplies are usually the thing that dies. Not sure what the other reviewer is talking about, but this adaptor works perfecting in converting an ATX power supply to an AT style motherboard. You can still buy AT / PS2 power supplies, but they are at least 2x the cost! Why bother when there are tons of good quality ATX power supplies out there for cheap!

NOT STARTECH BAIT AND SWITCH!

Reviewed in the United States on May 9, 2017

I don't know where they're getting these but they're not Startech. They work but they're definitely not the same quality as Startech and they come in an unlabeled bag. Be careful when you use them, The pin came out the back of the ATX connector and cut my finger when I went to plug it into the power supply. If anyone knows where to get the startech part LMK.

ATX power converter switch and AT power adapter cable

Reviewed in the United States on November 13, 2014

Allows me to use an ATX connector power converter for some other purpose, such as powering drives in an external enclosure. Provides a connector for a power switch so I don't have to do things like rewiring ATX power connectors to force the unit on.

I guess it could also be used for a system board with an AT power connector, but those are much rarer now than large drive towers and other things that still come up even with 'modern' advances.

This item is used to adapt modern power supplies to replace old AT-style power supplies that are used in my CNC machines. Even so, two of the wires have to be shorted in order to force the power supply to power up. It does save a lot of monkeying around that is required if this harness is not used....

This saves me from hacking an ATX power supply with a paperclip to short the connection. I replaced my DVD duplicator power supply, but didn't want to pay a high price for an old AT power supply. Instead I use an ATX power supply readily available and this adapter.

There were no instructions with the cable. I have since learned that the green and black wires are to connected to a power switch. It does allow you to run and atx power supply into one that will work for AT boards.

Terrific problem solver

Reviewed in the United States on August 26, 2014

This adaptor is way cheaper and easier to find than a AT power supply. I had an old PC's PS die and this was a great problem solver to adapt new ATX connectors to what the AT motherboard needed.
