There was a problem filtering reviews right now. Please try again later.
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.
The power supplies are nearly identical in appearance to the original units they were replacing, but the original units would overheat (with no load), melting the plastic case to the point there were holes in it, and eventually shooting fire out of the hole when the unit finally failed. the original units were rated for a higher current level as well, but were clearly the cheapest possible.
Other people here remark that they are having problems getting these units to hold their rated voltage under the load of a bunch of fans. I haven't done anything to test this units performance under maximum load, but when powering a single large hard drive, the 5v rail was right on the nose at 5.00v, and the 12v rail was at 12.28v. So with a nominal load of a drive rated at .5A@12v and .75A@5v, the unit performed flawlessly. And the unit runs fairly cool undder that load after nearly a week of continuous operation.
From a design perspective, I don't like to load any power supply past the 50% point anyway, as transient loads will tend to be several times higher than working loads(such as when you turn something on) so those of you loading this unit past 1A are probably overloading the unit.
Keep in mind that many of the cheap fans can pull more power than they are supposed to, as specifications may be a lie to get more units sold.
I did hook this up to a bank of 6 6" fans, and the measured voltage was the same 12.28v, but these were whisper quiet type fans, so their combined current draw is even lower than the HD I tested with.
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.
