Can this be run without the Wall Power Adapter? I don't need the USB ports, but I want the fans to run on the go.

Unfortunately it can't be run without the plug in wall adapter. I was hoping it could run off of USB power cord that is supplied with it but it turns out the USB attachment is only meant to power the LED's.

No the USB adapter is only for the 4 USB ports and having the lights on when it is not plugged into a wall the fans are off

No. It has to be plugged into the wall. The USB hookup is fine, but not necessary. You get two cables: 1. The Power Cord 2. The USB Connector I rarely use #2, but #1 is a must. =) Hope this helps. ~Mick

NO, your laptop won't have enough power. I tried that, it didn't work for me. Make sure you tell them to give you a U.S. adapter if you order it because you will get one from ASIA, if you don't.

No you need to have the Power Adapter to make the Fans run. For me it's perfect. I have an 18.4 inch laptop which fits perfectly, and a 17 inch laptop, which I mainly use. The two fans cool the laptops without any problems. I normally am at home when I use my laptops, so I'm always by an outlet. I hope that helps. Good Luck.

I don't quite know... You should probably ask the cooler master people via email. Personally, running this without the power adapter doesn't work for me.... But I haven't even tried. Though this is a good question I'm interested in finding out about... If I find an answer, I will post it here.

No it won't run off USB I imagane that the designers figured you would not be useing this away from a power source.

Yes. It just needs power to run the fans. There's no data being exchanged between the card and your system.

as this card doesn't have a fan onboard, auxiliary power is not needed. it should be fine with your system. I use the same OS and it is working very nicely.

You can use it without power. I haven't tried using it with multiple sticks without the power adaptor though.

My fan did not work coming out of the box so I never had a chance to use it with all 4 USB ports supporting devices. From reading other reviews, unless you have an external power source, it looks like the hub does not have enough power to support 4x power-hungry devices.

Great question! The speakers get their electrical power via your device's USB port! No wall socket adapter needed.

If power adaptor is an issue you can get by without using it. It takes the computer's internal 4 pin molex connector which is a day saver.

William, I returned this product as it failed twice. DOA both times. I wouldn't recommend this.BUT, to your question, yes you are able to switch off fans (0 RPM) and you are able to run two as long as you have enough power lines.

You don't need an adapter, 3pin connector will fit a 4pin socket. However, you won't be able to manage fan speeds using PWM, for that you need PWM enabled fans, which are 4pin.

if you're asking about the card itself - no. It gets powered by the PCIe bus. If you're asking about the devices plugged into it - it all depends. If you're trying to run something that requires 1 Amp @ 12 VDC - then you need an external power supply for your device. If you're trying to run a SSD/HDD in an external box - then the card on the bus power should power up your device reasonably well.

No problem dude! Its powerd by the USB port! You dont have to plug it on the wall

No, it only has a plug and play USB cord. Even when the laptop is off, the fan will run.

In general, I have found that the USB hubs that supply a wall-wart for power to the hub, do indeed NEED the power to the hub.Dick

The one I ordered didn't come with a wall power adapter. I just power my using the included USB cable. I believe, but haven't tried it yet, that you can use a USB wall charger to power it as well using the USB cable.

No, you don't need power for this great enclosure. This enclosure is very good can take my thick HDD too while many others cannot.I just connected only 1 USB 2.0 to my laptop without external power. I have to use 2 USB on my other enclosures. But if your computer cannot give enough power you can use 2 USB cable or connect external power.

No direct connection to power supply necessary or possible. Whether your existing power supply will be adequate is more a question of how many hard drives and other components are powered by it.

Power is provided by the same USB power running the cooling fan. No additional power cable is needed.
