SATA to Molex to 6pin PCIE?

[gwlaw99]

I only have two free SATA power connectors so I was thinking of converting two of them to molex with an adaptor then plugging thme both into a Y adaptor that leads to a single 6 pin PCIE for a video card. Will this work? Do I need both SATA connectors or just one?

Could I connect a single SATA connector to this adaptor

And then connect the two molex ends to this adaptor

And then plug that into the video card?


Or would I need two separate SATA to Molex adaptors to plug into the second adaptor?

Hmm that would potentially work but If your PSU only has SATA and no molex plugs it must be a low power output PSU whats the wattage cuz almost all newer video cards say at LEAST 450Watt PSU is needed and a 600w is recommended...So if your trying to rig all those adapters to a 250w PSU it's still no good...

Yea it is a 350w Dell PSU, but I have heard that this PSU is powerful enough for a 5750 which uses comparitively little power.

Do I only need one SATA cable with a splitter like in my first link or would I need to use two SATA cables? In other words will a single SATA cable (split into two molex cables) provide enough power to the video card or would I need to yse two separate SATA cables?

gwlaw99 - I think you heard wrong.

ATI Radeon™ HD 5750 System Requirements

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard

450 Watt or greater power supply with one 75 watt, 6-pin, PCI Express® power connector

600 Watt and two 75 watt, 6-pin PCI Express® power connectors for ATI CrossFireX™ technology in dual mode

 

[gwlaw99]

Well if you read reviews of the card, the measuremest show the 5750 using only 94w at full load. The only other power draw is a core2duo processor 1 hard drive and one optical drive.

el cheapo Dell PSU for this project?



Well... It's your computer, but I wouldn't think of attempting it.

 

[gwlaw99]

Well, I just talked to tech support and XFX and he said give it a try, but he recommended a new PSU as I would probably need one in the future anyway. So...I bought an Antec 600w PSU.

Thanks for all the input.

Yeah, hope nothing else fries when that Dell PSU gives out....

You might be better off grabbing a quality PSU from the beginning.
For $35 grab this Corsair 400w PSU.
It will have no issues running your system with a 5750.
