Hello guys this will be my first post here, some of you may find this ridiculous but i'm hoping it can work.

Basically im going to buy this computer:

and this GPU:

In the computer it has a 500 Watt PSU, but there is only ONE 4-pin molex avaliable, I plan to use this item to
convert the 1x 4-pin molex into 2x 4-pin molex

and then I intend to use this to make it into a 6 pin PCI-E

Will this work? Or will the GPU be under powered? Thanks!

Heres some of the power info on the card I found:

Thermal & Power
Power Supply Requirements --- 400 Watt Power Supply
Power Connectors --- (1) PCI-E 6-pin Power Connector
Maximum Graphics Card Power --- 116 Watts
Maximum GPU Temperature --- 100 C
Maximum Operating Temperature --- 100 C

Hmmm, I know the last step will work.

The first step depends on the wattage per rail. (http://www.tomshardware.com/reviews/power-supply-specif...)
You can split it if the PSU can handle the wattage this would put on the rail. But for that you'd need to know more than "Energy Star Qualified: No"
