This cable saved me from having to buy a whole new power supply when I added a graphics card to my Dell Tower. was easy to install and the price was amazing. Unlike the Molex adapters this one only uses one power plug instead of two.
PROS: Price Ease of Installation Only uses one SATA Power Plug
I noticed one reviewed complained on it only have 5 internal terminals. The reason for this is because you need two sata power connectors to be able to deliver enough wattage to match the 6-pin spec.
With only one power you are missing a 12v rail connection, if you are trying to power a high powered GPU with this and your PSU lacks the connections to run it, then that PSU needs to be replaced and I'm pretty sure this product isn't for you.
(I would suggest getting the dual molex to 6-pin for such things)
I noticed that when putting a heavy load on my GPU, the fan speed will decrease (with the fan manually set to 100%)
I am pretty sure this is caused by my PSU's poor 12v rail and/or the GPUs ability to balence out power draw- It might not be an issue if there was a second sata power on this cable, but I'm not sure with it so please take that with a grain of salt.
PROS: It allowed me to power my old HD 5750 without any trouble.
CONS: only has one sata power input? (not much of a con as this is designed to require such)
This will work if you are using a lower end video card where you can get away with using only 5 pins. I've tried my ATI 7850 and it did not want to work, not enough juice! Kinda wish Monoprice would have taken a picture of the front of the 6pin connector where you could see only 5 contacts as it would have saved me time and $.
Just what i needed when i found my computers power supply didnt have 6 pin connectors and sata connections laying around..plugged them in and they work like a charm to power my video card. Thanks again Monoprice
CONS: now if you could put 2 6 pin connectors on this monster not that i need it lol..
