![]() wire them to ATX and Molex connectors and plug your creation in to an unmodified PSU. Build a box with the requisite binding posts, switches, LEDs, etc. and attach the wires appropriately (See the photos for my version of this method).ī. Open the PSU cut the connectors off the wires drill holes in the existing housing insert binding posts, switches, etc. So, you want to hack an ATX PSU, but you don't really know where to start? There are basically two common hacks. Step 1: Background Information & Suggestions By using this information, you are agreeing that I am not responsible for any of your actions or their results, even if I totally am. You should clearly not trust anything that I have written. I am not a licensed electrician, professor of physics, PhD engineer, or any other remotely-credible title. Everything in this Instructable is correct to the best of my knowledge, but please use your own good judgement. If you're not afraid of electricity, then there's a good chance that you don't understand it and should do more research before messing with it. "Step 6" ~ Sources & further reading Requisite Disclaimer: Electricity is scary (where fear is equal to voltage x amperage / ). "Step 5" ~ Tips, tricks, warnings, anomalies, and conspiracy theories "Step 4" ~ A chart of wire-associations on other connectors (molex, floppy, PCI-e power, etc.) "Step 3" ~ A chart of wire-associations on ATX connectors "Step 2" ~ A list of standard wire-colors and functions in an ATX PSU "Step 1" ~ Some background information and suggestions for projects If you want a greater depth of information, see Step 6. This is meant as a reference guide and so I've tried to avoid extensive explanations. ![]() This isn't so much an Instructable as it is an Informable. My objective here is to give you all the information that you might need in order to hack an ATX PSU to meet your needs. We like to improve on what already exists and fit the product to our needs. My observation is that most makers, hackers, and mad scientists don't follow instructions very well. Although it may be some time before the whole industry follows suit.There are tons of Instructables on how to hack a discarded ATX (computer) power supply unit (PSU) into a lab bench power supply. With Intel also looking to reshape the gaming PC power with the ATX12VO specification, which takes the burden of 3.3V and 5V conversion off the PSU and integrates it into the motherboard, we could see a significant shake-up in the ageing connection and power standards that have ruled PCs for decades. ![]() HardwareLuxx reports that the new 12-pin connector comes with six +12V pins, four ground, and two Sense pins (used to indicate what configuration the connector is being used in, in order to adjust power delivery accordingly (as is the case with 8-pin and 6-pin connectors).Īs listed on the exterior of the box, the Seasonic power connector recommends a PSU capacity of 850W or more for use with the cable-and one would assume the graphics card to go with it. Best CPU for gaming: the top chips from Intel and AMDīest graphics card: your perfect pixel-pusher awaitsīest SSD for gaming: get into the game ahead of the restĪ traditional 8-pin PCIe connector (or 6+2-pin) features three +12V pins and five ground pins, and is able to deliver 150 watts per connector to a graphics card.
