## Questions & Answers

**Q: Can this power an external graphics card? the board it's connected to says dc 12v, but i hope i won't be putting too much on it.**
A: This may be sufficient, but you should first look up the max watt/amp draw from the card manufacturer to make sure that it's less than 500mA at 12v (<6w). Feel free to call if you'd like any help: 425-821-6400

**Q: Why did my product come in with two metal sockets instead of four?**
A: This is a 12v supply, only the 12v and corresponding ground pin are used, the other 2 sockets would be for 5v and ground if this were a 12/5v supply

**Q: Is this powerful enough to run two fans with with a splitter?**
A: Depends on your fans.  They may not at full speed.  Most fans use around 300ma.   This is rated for 500ma.  In practice, you won't notice the difference, and you are good to go.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked perfect for 12v LED strip
*by C***R on February 3, 2024*

Had an old 12v LED light strip from my PC that came with a molex connector. Wanted to use it to mount inside my 3D printer case for more light and this adapter solved the problem of how to power it as well as having enough cord to mount it where I wanted. Obviously only has 12v power (some people complain about the missing pins, but those would be for 5v power in the PC) and had no problem powering the light. The molex fits tight, but feels very secure once it's in.

### ⭐⭐⭐⭐ Kind of a no brainer. You need power? ...
*by M***P on July 19, 2016*

Kind of a no brainer. You need power? You bet your ass you do. Where are you going to get it? You know where you're going to get it, right here. if you need 12 volts of Edison loving DC power, you've come to the right place. Don't even think of trying "like some of those other knobs" to use this as a 5 volt source, that's not what it's for you dummy. This thing is for those only interested in getting all of them volts in the range of 12. If you know what you want, and that includes electricity for your stuff, get this.

### ⭐⭐⭐⭐⭐ 💢 Good Quality, As Advertised, Works Well. 💢
*by @***K on October 9, 2016*

This power source is exactly as advertised, and functions just as it is supposed to. No issues whatsoever. We purchased this to power an external computer fan, and it has worked out well for that purpose. Good quality product at a reasonable price-point.✅ Overall, very satisfied. If you have any questions leave them in the comments and I will be happy to answer.
