Q: What is the difference between the power BV line and the power YJV cable?
You can use sc. if too long, or bend the best use of the bridge
Q: I have a hard drive that has an enclosure is there any way to take an internal 3.5hard drive and convert it to an only usb cable portable hard drive with no power cord?
No. Not a 3.5 hard drive. You can do it with a 2.5 laptop drive because the drive mechanics and electronics require less power. A 3.5 drive requires too much power for USB to provide. Though... In the near future, you will see USB ports that are capable of supplying more power than the standard .5 amps that USB currently provides. So after they come out, you might see it being a possibility then.
Q: Hi! I want to buy I new Hard Drive but I've got a problem. I have the IDE conector but I don't have the Power Cable. It is connected to my Video Card. Can I add a new one? Can I use a power cable from a optical drive(CD/DVD)? Thanks!
All you need to do is pop down to your local computer store and get a power splitter, just make sure you get the right type, IDE and SATA drives have a different kind of power connector, so just make 100% sure before you buy!
Q: I got two mobile GPS units for my car which use a mini USB interface for powering. One of the units didn't come with a cigarette adapter so I am trying to figure out how to power it. Can I just use a normal USB cable? I would tap the red wire into the fuse box in my car, and ground the black wire to the frame. So:-Can a mini USB cable handle 12V for ~5ft-Is that the right way to connect them?Thanks!
no because it will explode it only takes 5 to 4.5 volts and 2 to 2.5 volts i recommend using 5 volts and 2.5 watts bye
Q: I dont understand what it says about Peak and sustained power, also the cable says it needs 12v DC, and the power supply gives 650 watts. I don't understand any of this, can someone please explain this to me, and if this power supply doesn't work, please give me examples of ones that will work. Longest answer will get best answer.Thanks!
That Xbox power supply cable is pretty cool! I've never seen those before. Ok, as for the power supply questions: Peak power is the maximum amount of power the unit can supply for a short period of time (a few seconds at most). A computer, during start-up, will use quite a bit more power than once it has achieved steady state. This is because drives have to spin up, semiconductors have to power up, etc. Once everything is up and running, the power draw drops to nominal or steady-state Sustained power is the amount of power the unit can supply non-stop. When purchasing a power supply, always give yourself leeway. If a supply indicates it is 650 watts sustained and 80% efficient (gotta look at that efficiency!) then it can supply 520 watts of power continuously. Even at that, I wouldn't want to run it past 450 - 475 watts continuously. 12v DC is the high rail on a power supply. Different parts of the computer require different voltages to operate. Drive motors typically need the 12v DC, where as memory needs less than 3 volts. A computer power supply has different rails or supply wires which supply the following voltages: +12 volts DC, +5 volts DC, and +3 volts DC (there are some others but those are the key ones). I don't know what the power requirements are for an Xbox 360, but it obviously needs the 12 volt and 5 volt DC rails to power it. Anyway, the power supply you've listed above is more than adequate.
Q: If you have an electrical device (e.g. a laptop), you'll sometimes notice that near the place where you plug the power adapter into it, there's a sign. It's composed of 3 circles, minus on the left, O inside a C in the middle, and plus on the right.What is this? And if I want to read/learn more about it where should I go?
If you look at the jack that go inside the power input you will see that it is an outside connect and an inside one.The O is the inside connect and the C is the outside one.Because it is a DC power adapter it has a + and - polarity .O,the inside ,is the plus and C,the outside,is the minus. Also on the adapter you can see the same thing! This is because some brands use the outside connect as + and you can burn your device if you use it!!!!
Q: i bought a car from some guy.he had 2 amps but he took out onehe had the power cable running from one amp to the other. i just recently bought another amp and i was wondering if its safe to do this.he said it was working fine.he was powering 2 10 subwoofers.thats what im planning to do
its safe but its better to run 2 separate wires due to you are wanting to use more power and one wire has a max load that it can handleyou run 2 and you will have more power to each amp
Q: What cable am I supposed to use for power?
That kind, it's kind of hard to see on the OKorder pic. Usually your switch should come with a console cable and the power cord, unless you bought it used. The person probably kept it.
Q: i need a power cable for a digitech rp 10 guitar effects processor. my teacher gave it to me and it doesnt have a power cord. if anyone has one please let me know. ill pay good money. but i wont pay an outrageous amount.
I only use my multifx for clean effects, since I've never found a distortion that sounds any good from any of them (even the newest aren't all that great). Turns out that most multifx units have pretty decent clean sounds. Whodathunk? I found a Boss GT-3 for 100$ (a good deal) and it's one of the best multifx I've ever used - again, only for cleans. The Boss GT-x series are so versatile that they're actually kinda hard to program, until you get used to them, but the sounds you can get out of them are far higher quality, in my opinion, than most other effect units out there, at least below the 500$ mark. The coolest part about the GT-x series is how you can program them to change sound over time - say, as you move the expression pedal it morphs from a flanger to a chorus, and all the while the delay behind it grows in volume and intensity, and everything is synced together to the same bpm with a tap tempo. It's simply sick. I don't have a lot of experience with the newest Digitech stuff, most of my experience is with models from, I dunno, almost a decade ago. They weren't that good back then. My best advice is to scour for cheap units second-hand that you know have good customer reviews, and go for them. Always play before you buy! Saul
Q: i have a 97 chevy malibu and i need to know where to run the power cable through the fire wall. or where could i get a diagram that is simple enough for me to understand...
if you can fit under you dash you can see that mostly all cars and i say all cars becuase iv been doing this for over 10yrs and all cars have a wire that comes from the stearing colum that goes through a rubber gasket into your engine. What we do is the gasket already has a hole in it push your chair as far back as can go and shimmy under the dash bring a flash light becuase its sometimes hard to see and youll see a round black rubber type thing with a wire already running through it. Thats the one to use you might need a long metel thin rod or use a meter coat hanger. Using black electrical tape, tape some of the power wire to the tip of the hanger and push it through the exsisting whole as far as you can then go into your engine and you should be able to see the wire then just pull it to the length you need to wire to the batter dont forget to install a fuse at least 30amps or more depending on how many watts amp your running it for. Dont worry if the little round gasket pops out it can some times do that once your finished with pulling it out and you know your not going to be pulling on the wire again. Then you can actually push the gasket back into place that only if it popped out if it didnt then your good to go.
