## Description

desertcart.com : Coolerguys 100-240v AC to 12 & 5v DC 4pin Molex 2A Power Adapter (2A, Without On/Off Switch) : Electronics

Review: Reliable Power Adapter - This Coolerguys AC to DC power adapter works as expected, providing stable 12V and 5V output through the 4-pin Molex connector. Build quality is solid and setup is straightforward. A good solution for powering components that require Molex connections.
Review: Perfect for my needs, and probably yours too. - This product is a lifesaver honestly. I wanted to keep my reciever cool, and I have tons of used computer 120mm fans laying around, but with no way to give them power since they use molex connectors. Enter this product and bam, problem solved. You just plug it into your wall outlet and you're able to run any molex powered device off of it. Depending on your fans voltage rating, you can get quite a few fans running off this thing. I was personally was able to chain 4 with no issues, and now my reciever is nice and cool when it's running. This product is definately a nice quality, but I will admit the price seems a little steep to me. I feel like it could be a little cheaper. But I looked around the internet and this price was pretty consistent with competitor pricing that I could find, so I decided to order based on Coolerguys reputation being my deciding factor( I've dealt with them pretty often because I build computers and never had a problem with them). If I could have found a different molex power adapter for a significantly cheaper price, I probably would have went with that though. This product would also be good if you wanted to run some molex powered LED cathodes or lights to light up your computer desk a little. I'm thinking about ordering another one for that use.

## Questions & Answers

**Q: Can i to use this power supply for hard drives?**
A: I don't use it for connect hard drive, but the voltage and ampers maybe working with it,, so there are another solution for connect hardrive. for example  SATA/PATA/IDE Drive to USB Adapter Converter

**Q: Will this power adapter work to the sunshine-tipway 5.25 inch aluminium 5v - 12v pwm led fan controller and 6 arctic f12 pwm pst case fan,**
A: You shouldn't have a problem with it, if you can't use the SATA power connector. Just have to add up the amps for the fans, and if it is above the rating of this power brick which is 2 Amps, you would need a power brick with a higher amperage value. There are a few fans that came up from what you posted, only a few have the amperage it uses displayed, which form the ones I saw was .25A. So if you have the .25 versions, 6x.25=1.5A so that would be good.

**Q: Can this provide enough juice to power two 3.5" hard drives if i use a molex splitter?**
A: Sure.  If works like the Power supply of a PC.

**Q: Will I still get the 3 year warranty if I buy it off of Amazon?**
A: Hi, I have had mine for years providing power 24/7/365.  I would think they would on all there products so long as you have a receipt.

### ⭐⭐⭐⭐⭐ Quality product
*by E***O on February 3, 2024*

I wanted an external power supply with Molex connector to run an out of case diskette drive (if anybody remembers what those are). Out of the box, it appears to be excellent quality, good construction. Voltages test as specified. Powered up the drive. Important Note: There are four pins on Molex connectors for this type of power supply. The outside connectors are for the two different voltages, 5 and 12. The two inside connectors are ground. In SOME supplies only one of the inside connectors actually exists; the other is a non-functional dummy. That can be a problem. With this adapter BOTH inside connectors are grounds. The description does not specifically address that, but I verified.
