We previously said you should never mix power supply cables from modular power supplies. This is true, but there's a way to do it safely with continuity testing.
Ad: Buy Thermal Grizzly Kryonaut on Amazon (geni.us/gntgkryo) or Conductonaut Liquid Metal on Amazon (geni.us/gntgcon...)
You can find a cheap/starter digital multimeter here: geni.us/teoa
This is pretty basic stuff. In this video, we show how to do a simple continuity test to determine if one PSU's cables can be used with another PSU. You should typically avoid mixing and matching power supply cables, as doing so can cause the death of components or power supplies. It's easy to accidentally short 12V to ground, for instance, or you might get lucky and just be unable to boot. It's still possible to get a PSU running with cables that aren't native to it, however, and that's what we show today.

@@g.s777 Extensions won't damage your PSU, because like their namesake they only extend the end that plugs to your component. The location of the pins is the same, they don't switch places and won't matter since you're extending the 24pin, 8pin EPS, or PCI 8/6pin. OTOH the modular cables that come out from the PSU the side that plugs into your PSU have propietary plugs and pin outs and they may switch, move around. Those need to be specific to your PSU or line of PSU, even within tha same brand the pin out can change from model to model. TL,DR: Extensions doesn't matter what PSU you use it on. Modular cable replacements, you need the specific for your brand/model.

Let me make a niave comment, wouldn't it be great if PSUs had a standard for the cables as well as the other standards out there (size ATX, efficiency 80+ etc). I wonder why there isn't more consistency, feels like it'd be a win for everyone? I'd love to keep my cable mod cables for my corsair power supply for 2-3 builds, perhaps I can after watching this.

I suppose it comes down to how willing the manufacturers are to work with each other. The trouble is that everyone thinks they have a better "standard" than their competition, and no one really wants to concede and adopt what someone else is using. EVGA, for example, has universal power headers on some of its PSUs (so you can plug EPS12V in anywhere, or PCIe anywhere), but this is expensive and bulky. While EVGA likes it as a marketing point, another company might not for either cost or size reasons. Then you have the inverse -- some company make extra small connectors to meet tinier form factors, which introduces different complications. Fortunately, the system-side is standardized, so we only have to worry about one end.

Wow... how lucky have I been. I've been mixing and matching power supply cables for years without an issue, thank God. I assumed the keying on the pins was designed to prevent you from plugging the wrong cables into the wrong slots and causing a problem. I've had some cables that *almost* matched, but had one or two pins differently keyed, and so of course in those cases I was not able to use the cable. Who knew that wrong cables can have right keys? What a bizarre thing for manufacturers to do. Why even key at all then?

The accuracy goes to useless really quick near the single digit range unless it's specifically designed to handle it. I've fallen into this precise trap myself. If you want to measure it without a fancy meter anyway, the right way to do it is to send a known current down the cable (1A should be good for these cables) and measure the voltage drop (or known voltage and measure the current, but you need a really low voltage), then use Ohm's law to calculate the resistance.

As long as the keys match you can also swap wires around to go to the proper pin on the power supply. I did this with needing 4 Molex cables for a server backplane and used random Corsair and Evga cables which used standard 6pin pci-e plugs and swapped around the wires to match the power supply I was using. They make tools to remove the wire from the plug though I used a staple folded in half clamped in some locking plyers and spread out about an eighth of an inch with a flat screw driver. I also sanded the inside of the two ends of the staple to make it easier to insert into the plug and worked great since it's easy to make again if the staple breaks instead of buying a new tool that also break periodically. On another note power supplys have a safety feature that checks the wiring before powering on so a good power supply will just not turn on if you are using a wire with the wrong pin out but that is not something to rely on when expensive parts could die in a cloud of blue smoke. I always recommend shorting the power up pins on the 20/24 pin plug and with a volt meter testing each unknown cable has the proper voltage or ground where it is specified to be on the plug.

be careful with that i have 2 power supplies, and when i tested the voltages for a molex connector cable, the voltages were WILDLY different. when plugged into one of the PSUs, it read 3 volts between certain pins, 12v between other pins. plugged into another power supply, it gave ONLY 12v on the pins. so, even if the connector can fit in the power supply, that does NOT mean the wiring and power levels are correct for that connector.

Just the week before, my son's ANTG PSU died in his CYBERPOWER pre built from 2016. Was able to canablize all the cables (non modular) from it and used connectors from 2 of them, a multi meter, soldering pencil and KZbin (to see how to remove pins from connectors) to make up a solid Molex harness that works great. I used the multi meter to measure continuity, resistance and voltage for each wire.

It can still be dangerous to mix and match some cables since some PSU cables have capacitors and sense lines going back to the PSU. That means some of the PSU side pins are shorted together which could lead to issues. How many PSUs have this feature I don't know but it's present on some higher end Corsair ones.

Overall this is an excellent video, with a lot of good information in it. Only a few mistakes which I have outlined below. 0:43 "or you could damage the power supply" Unlikely unless you have a cheap power supply, almost all modern units have short circuit protection and whatever you're plugging it into is unlikely to have voltage present at it (unless it's being powered from another power supply) in which case feeding low impedance voltage into your PSU ground can damage it depending if it's got protection on that side as well, but the "worst" you're likely to get is a short circuit, which will usually cause the PSU to shut down. You have a significant chance of destroying the part you plug into it though. if you connect one of the rails and ground to a ground line on your GPU/MB you will short them and the short circuit protection will engage. However, if you connect a 12V rail to a minor rail you stand a decent chance to blow up an output capacitor. This goes doubly true if you connect the -12V rail to anything. 5:23 "we're just going to use a resistance check, so it's a continuity test" If you click your multimeter one click clockwise from where it is, you'll put it in continuity test mode, it will "beep" when it detects continuity (usually under a few hundred ohms check your user manual. a cable is less than 1 ohm so it will definitely work) This saves you from having to stare at the multimeter all the time and will save a LOT of time and effort. It was also left in autorange mode, so it has to range through all the resistance ranges, which takes time. If you *are* using the resistor check for this sort of thing (and there are good reasons to use it, but continuity testing is best done in continuity tester mode) then leave it in manual range for whatever you're working on. it will be much faster. 6:49 "OL" stands for "overload" so it's "OL" not "0L" no big deal though. 6:56: You are charging the capacitor that's in the cable with the multimeter. This is expected behavior for a cable that's got capacitors in it when you put the leads across the power and ground for it. Try measuring the "voltage" of a capacitor and you'll see the same thing. 11:20 "pin 1 doesn't need to go to pin 7, ... it just needs to go to 5,6,7 or 8" This is almost correct. It most cases this is fine, but in some cases the PSU might have different rails attached to that connector, and if you wire them up differently it can load up one rail more than the others on the PSU which can overload the rail while keeping the other rails the same. This was a major concern with my last PSU, which I had to completely rewire. However in most cases it's ok.

@@ReubenHorner Hi Reuben, that's a good point to bring up, one that I hadn't considered. (I didn't think about modular motherboard cables). First of all, let's recognize that this will definitely happen if you put both a 12V and 5V into the ground connector of the motherboard. I think the PSU itself will be OK if you do this, but you will blow up an electrolytic capacitor depending on a number of factors. This is doubly true if you connect the -12V rail to anything. I still think the rest of the unit will be OK, but I wouldn't expect every user to be comfortable soldering new capacitors into their PSU. I'm just used to proper lab PSUs with output protection (sometimes even including gas discharge tubes) on the output, so they'll be OK even if you accidentally put -1200V across it.

Basically, I read the output specification on the power adapter that came with my monitor and saw that the output was 12v at 0.75a. Used my multimeter to confirm the voltage and then cut apart and clamped the line to confirm the amperage. Then I completely cut the wire and soldered it to an old molex extension I had. Plugged that into my test bench PSU and confirmed with the multimeter that the output was the same, then ran the cable through an open PCI slot on the case and plugged everything in. In the end I freed up an outlet and my monitor auto-turns-off with my PC. Make sure to get the polarity right, that little dash could be the end of your electronics if you don't notice it I also have my wall-powered speakers rigged up with an automotive relay to 'unplug' my speakers when my computer turns off, but I can't recommend anyone does that unless they have experience working with mains power. Instead, if you want something to 'unplug' with your computer, there are specialized power strips that will shut power off to their outlets when one outlet isn't drawing power. Like this one - www.amazon.com/TrickleStar-Outlet-Advanced-PowerStrip-Joules/dp/B00JPDYYSM/ref=sr_1_4?ie=UTF8&qid=1541216912&sr=8-4&keywords=automatic+power+strip

You can always use a terminal tool or sewing needle to depress the retention tabs holding the wires in the terminals (plastic connectors), then move the wires to their correct locations in the terminals. And then if you can find a kit with the right terminals and connectors you can use a pair of Blue-Point PWC47 crimpers to make your own cables.

I actually made the best one yet, to date, last night. Scrap inkjet printer. There's a tension cable...no strip? the printer tram rides on it and it is under high tension. The left side connection is a thinnnn and very rigid...spring rigid... piece of metal. It takes a good sheet metal sheers to cut it. Cut out a .750" x .140". Then cut down the middle about a half inch so I have 2 - .070" tangs connected at one end. Then with my finest pliers, finesse and patience, started twisting them carefully until they resemble a tiny tweezers. With the ends slightly inward, the hardest part is inserting it into the plug. Then it's just push the extractor and pull the wire. The tools I had in the past didn't seem to work like they should. The needle method works but usually distorts the pin...along with the assortment of other items I have tried in the past. Using new pins is great and the correct crimper tool ensures a solid connection, but, a soldering iron is more versatile for the money. And if your customizing your PSU cables, you should know how to solder also for those other projects. But yeah! Bought a Channel Well Technology, CWT, to replace my old Seasonic PSU. (That was actually the first Brand New PSU I ever owned.) CWT uses all black, flat, ribbon style wires for the cables. Very unclean look. My old Seasonic cables are already setup for my PC components. Their plug, my wire harness. Now, all I got to do is stop telling you about it and finish the damn thing. I got online with hopes to find a pin-out diagram. I know how to trace the wires and all that. It's just that, it's late. I'm tired. And I want to have that redundancy for it being correct the first time. The saga for why my tower is...has been down for a year now is much longer than this reply/comment/jabbering. I really need its additional abilities...although my laptop is great, wonderful, awesome...okay, great and wonderful...it just-is-not-the same...Shit! I hear our rooster crowing.... UPDATE: Apparently it was an anomaly. I could never get it it to work the same way since so...went back to the needle and modified safety pin...the safety pin mod is great! all you have to do is....

Very helpful video. For my PC I had to so something somewhat similar for the LED strip (a very long yet inexpensive one that I got from a hardware store) to connect it to the power supply. It uses 12v, but the connector has nothing to do with a molex, so I had to properly match the 12v and ground pins from the LED strip connector to the molex. This allowed me to save quite a bit of money, since the generic LED strip is significantly longer yet cheaper than those made for PCs.

I made pinouts by testing each cable, and it's easy enough to swap the pins around if needed. Question, though, when looking at the pinouts between my EVGA 850 G3 and my old Silverstone 700w SST-ST70F, the 8-pin VGA pinouts are exactly the same in where the +12v pins and ground pins are located, but the two bottom middle ground pins are swapped. Does this matter? A ground is a ground, right? Either way, that's the only difference, and everything else is the same. I swapped the pins anyway to be sure, so I was able to use a spare EVGA 8-pin VGA harness on the old Silverstone PSU.

My friend was having problems with his computer. The PC shop couldnt work it out and eventually he decided to just buy new parts and just reuse his power supply. After getting it set up he found that the computer would crash under load so he decided that the PSU must be faulty. He bought a new PSU and plugged it in but left the old cables in the machine. There was no smoke or anything but but it didnt boot. Now after swapping the proper cables into the system it still wont boot. It says something along the lines of "USB over current, system will power off after 15 seconds". He has tried disconnecting all devices except for power and HDMI but it still keeps saying the same thing. Has he fried his mother board? If so, is it likely to have damaged anything else? Its ridiculous that this is still an issue. How many people have fried equipment just because they didnt know?

Did this to use some extra SATA cables from an older Corsair PSU to use on a newer corsair PSU.

Obviously check, double check and triple check that you arranged the pins right before you plugs anything of value in.

The location of the wires that enter the back of the connector correspond directly with the 3 pins they are located behind.

OR if you are OCD about it, you could just use a Molex Pin Removal Tool, and then reinsert the Pin or socket connected wires back into the connector on one end of the cable in the order that you need them to be. All Computer Power supplies use the same 'Molex' type Pins or Sockets on either end of the wires which go into the connectors. (The Pins are roughly the same diameter as a solid copper 12 gauge wire without insulation). The sockets are sized to 'sleeve' them accordingly. Each Pin or Socket has their base with two 'Flared out' sides to prevent them from being pulled out of the connector. A proper 'Molex Pin Removal Tool' will have two cylinders one to fit over the Pins and one to fit over the Sockets. Push the wire into/through the Connector while sliding the appropriate size 'Molex Pin Tool' cylinder over the Pin or Socket. Then Pull the wire out of the Connector. Once all the wires are removed, then continuity check them, and insert them into the Connector where they should be, to match the Connectors connections of the other cable.
