What Power Supply Do I Need

How many watts power supply do I need for a 1000 watt amp?

I haven't seen many people do this but I figured since I had the equipment sitting around I might as well use it. I've got a 1000 watt (500w rms) car mono sub amp. I want to power it indoors. Heard of people using computer power supplies to convert from 120v ac to the 12v dc. But to power my amp does that also mean I need a 1000w power supply? Not sure if it's an equal proportion. If that's the case, the power supply will be in the hundreds. At that point is there a good audio indoor amp that puts out the same numbers that anyone would recommend?

How much power supply is needed to run i7-7700k and 4 GTX 1060s?

Hate to break it to you, but GTX 1060s are not SLI compatible. That being said, it is possible to use software to boost your performance with separate graphics card, so I'll do the math anything.An i7 7700k has a TDP of 91 W according to IntelA gtx 1060 (Both Models) has a TDP of 120 W according to Nvidia, so four of those would total 480 W.91 + 480 = 571 WI would be safe and go with a 700W power supply depending on if you want to overclock and taking into consideration other components.However, a 1080 costs about the same as 3 gtx 1060s and will outperform it in any game while using less power. I suggest you go with that instead of a wonky 4 card fake sli setup. :)

What power supply do I need to power up 25 chips of 5w 12v SMD LEDs all at once?

The correct supply for the job is a 10–12A constant current supply with about 14v open circuit. The important number driving an led is the current, there is very little voltage change in an led to a huge current change, and they are nowhere near linear either. Ideally it would be better to use 5 2.5A supplies for 5leds each, or even a 0.5A supply each for the best lifespan/brightness.A constant current supply is easy to get, but also dead easy to make, all you need for a super simple “current limiter” circuit is one transistor, one resistor and a capacitor. Just feed it enough 12+V (be sane on the +, if it is receiving 18v and outputting 12v as nominal the transistor has to sink 2.5w per 5w led, so get heatsinked transistors or stick under 13.8 ;) volts

Does speaker need to have power supply?

Speakers generally need to be powered by an amplifer to work.
If the amplifier is built in (called "powered" or "active" speakers; the kind desktop computer systems use), they need a power supply for their built-in amplifiers. If the amplifer is not built-in (sometimes called "passive" speakers to distinguish them), then that external amplifer has the power supply.

I say speakers "generally" need to have an amplifier to work, because there are some extremely efficient little passive speakers designed to work directly from just a line or headphone level signal from an MP3 player. These sound awful (they're not very loud and have practially no bass) but they do exist. Perhaps that is the kind of speaker without a power supply that you have that works on the DVD player.

If you hook up that 8 ohm 50 watt speaker to a line or headphone level output and put it right up to your ear, it should work like a headphone element (it won't be loud, but you should hear some sound if it's right up to your ear). But to get any volume out of that speaker, you will need an amplifer or stereo receiver between the DVD player and it.

What pc power supply do i need to power a 1000 watt amp?

i need to know how many volts, watts, and amps i need in a pc power supply to power a 1000 watt amp and sound good. here's the link for amplifier specifications, https://www.thedeepdiscount.com/p-3015-visonik-vpb210pk-car-audio-1000-watt-dual-10-sub-enclosure-amp-combo.aspx

What's the minimum power supply I need for my PC?

The largest you can afford.If your building a Desktop, then I would put in the largest wattage supply that will physically fit.Many would say WHY? Well the power supply of a desktop only supplies the amount of power the computer needs. So having larger is better, as it will last longer, run better, and as you upgrade and add on hardware, it is assuredly going to take you into the future.For a laptop, I advise again, getting the larger wattage for it, that still plugs into it. Again the WHY? Because again it only outputs and consumes based on the power the notebook needs. But too small and the notebook will not charge properly and may fail during operation.500 watts is a good minimum for any desktop.90 watts is likely the most you can get to work with your laptop.Proprietary you have no option than to go with what the manufacturer gives you.Micro ATX supplies, can usually be had in at least 350 watt sizes however.Power consumption is based on the video card, CPU, and number of drives in your system, and then add more just to assure it will not shutdown under the most demanding tasks.

What power supply do I need for an i3-7100 and an MSI Nvidia GTX 1050? Is a 450-watt PSU enough, considering the future upgrades?

Yes definitely enough.I'm surprised by seeing many of them saying its not enough, some even say that go for corsair vs 550(which is cheap and not for gaming) .Gtx 1050 and gtx 1050ti can run at 300w powersupply , which is minimum, you cannot overclock with 300w , my friend runs gtx 1050 at 240w ,but its his own risk , but yes the performance is almost same but 450 w is more than enough even if you overclock , actually 400 w is enough , but 450 is good. I'm pretty sure you are not going to upgrade for at least 3 years now , if you upgrade you will most probably end up with a gtx 1450 or gtx 1460 , which would also require 400w , even if you go for 1470 (500w) then most probably your PSU would have become old and you will probably replace ( a PSU should not be used more than 5–6 Years) , at that time you can buy a powerful PSU .It is necessary to buy a good quality gaming PSU for at least 4 or 5k for 450w , since the quality is important more than load watts in your case. Don't get cheap PSU for 1 or 2k from Chinese or don't go corsair vs series (other corsair series are good)

I need a power supply for an acer aspire am1610-u1202a. what kind of power supply do i need to get that works?

That PC appears to be using a standard 250W ATX power supply. http://www.geeks.com/largePic_All.asp?In...

You could use any 250W or higher ATX type power supply. Just make sure input voltage of power supply is set to same voltage as your AC outlet. Also make sure the 4-pin 12V ATX power connector (yellow and black wires) is connected to motherboard.
