Powermax 12v power supply

[@Ritalie]

I've been using a 14.2 amp XBox supply for 10 years, powering a 3 channel 600W amplifier with 8 speakers, plus a 12 inch subwoofer. You can run it near full volume without clipping. It takes all 14.2 amps. At a volume level where you feel like it's too loud, it will cut off, but the whole house is shaking by that point. It certainly doesn't need more power, but I want more power. I was shocked to hear how much volume you can get from just 14.2 amps. The voltage is 12.30 volt, but drops to 11.90 volts before it will clip and shut down. The capacitor in the XBox power supplies is tiny, so you need a very large buffer capacitor (I don't have a buffer capacitor unfortunately). I do want more volume, and more power (duh!) so thanks for this video! I wasn't sure where to look.

Hello and thanks for watching, I have heard of people using the Xbox power supply. Before my Powermax setup I had a computer 5amp power supply that barely powered amplifiers. Going through that made me want a decent 12v power supply and purchased the Powermax. Till this day I haven’t had a problem and have powered a 1000 watt amplifier with it, so I’m happy to say the least.

I was previously using a repurposed computer PSU as well. Despite it saying 650 watts it didnt do the job very well. It was good for checking that an amp I just bought powered up and wasnt in protect mode but thats about it. Some amps wouldnt come out of protect because it could tell the wires were too small of a gauge (MTX amps). I came across these Powermax supplies and ended up buying the PM3-75LK. The 75 amp version of the one you have here. It is capable of up to 1095 watts continuously so that will be more than sufficient to test pretty much anything I need to. I made a little setup with some 4 gauge going into a distribution block that had multiple outputs so I can hook up the amp, headunit etc. Setup works great and the price i got it for was amazing because they had made a mistake, thats why I bought the 75A, it was priced at $119 and the 100A was $279. The 75A should have been about $219-239 but i ended up getting it for less than the cost of the 30A model.

[@93dajjdg]

Wow you ran into a deal only paying 119$ for the 75amp version of the power supply. I also previously had a pc power supply that I used in the exact same manner as you mentioned, I was only able to check if amps and head units would turn on and play them lightly.

Yeah, hulkin' up the ole power supply . I was using a ps out of a Dell desktop pc that was good for 14 amps, but upgraded to a Corsair TX850 I pelfed from a gaming pc. This puppy is good for 80 amps and hasn't once gone into protect/shut down. Currently is supplying the juice to a MMATS Hifi4250 (which is one badass amplifier). * 200 rms × 4 @ 4ohms 400 rms × 4 @ 2ohms 800 rms × 2 @ 4ohms bridged $1,300 msrp and would be worth every penny, but I scored it used for $90

[@josephsaucedo8691]

It also the cheapest easy way to run a 1000 plus amp in a home set up with out having to pay the over priced amp plates and rack amps you just have to under stand the power unit alone not enough because it can only handle about 90amp by it self it need to be just like it is in a car set up you don't only run a alternater just for your stereo everything has to work together for it to handle the full amp power thats why people have there cars running on sound demo's there not one part can do it alone it a system.lol🤔👍👌✌️💯🍻🎶

Im on the fence of getting this 100 amp or the taramp 120amp power supply. The taramp i can power a deck, amp , crossover, and small amp for mid/tweet. Im just affraid this isnt gonna be enough power. I plan on running a skar 1200.1 amp.

[@93dajjdg]

I believe either option is a good decision, I have never had an issue with not having enough power for an amplifier. But I will say I have learned that running a power supply directly into an amplifier can cause an issue, some amplifiers don’t like to be plugged directly into a power supply. I recommend using a battery or a high power capacitor in-line of any 12v power supply. If you watch more of my videos you notice I eventually ended up running a small battery to make all amplifiers run as they should. I hope I helped with your decision, whatever you do is your decision and at your own risk. Thanks for watching and please like and subscribe.🔊🔊🔊

[@DarkenFool]

Do you know if the converter will stop sending power once it detects the battery is full on fixed output ?

[@93dajjdg]

I’ve never tested my power supply in that manner, I’m always trying to play it safe. Whenever I have the power supply on fixed mode it’s always for a short period, again playing it safe. Be careful, thanks for watching and please like and subscribe.🔊🔊🔊

[@JayRSwan]

That's the beauty of DC. Your battery will stop charging when it's complete. However, lead acid battery life will be shorted doing this, as they do not like max amps past 80% charge. If you want to use this as a full-time battery charger, you will not want to use fixed voltage, as there is no float charge mode either. With extended time at max, volts are unsuitable for batteries; their float charges are always less than the bulk charge. .

[@josephsaucedo8691]

You should also get a deep cycles battery AGM or at least a capacitor to hook up to that power supply so you have some stored power just to let you know 🎶👍✌️👌💯🔧🍻🎶

@@K_Vang23 I noticed some amplifiers don’t like to be directly connected to a power supply and what fixed that problem for me was getting an inexpensive capacitor that I found at Walmart. I will say I give credit to subscribers for hinting that idea to me. This again is what fixed my problem, hopefully your amp doesn’t have a problem causing a hum but I would recommend trying a capacitor like I mentioned. Hopefully this advice helps, a visual example of the capacitor being used on the bench would be found in videos that can be found in the video library. I have since upgraded from a capacitor to a small battery, all is explained why I do anything in the videos.

A 45a fuse will run the amp but more then likely the fuse will eventually fail. From personal experiences I have done what you are asking and have had no issues, probably chocking the amp from power but never experienced the fuse blowing out or melting. I also try to use common sense and remember that I’m running a small fuse and not to be surprised if something happens. Whatever you decided to do, use your best judgment and common sense.
