658983 2008-04-15 06:58:00 Hey guys I have an Acer Aspire M1610.

The PSU in this is one of the newer? ones which only really have sata power connectors, It only has 1 4-pin molex available.

See the thing is I want to connect my new graphics card which needs external power, the pci-e convertor requires 2x 4 pin molex. Would it be safe to use a splitter for a 4 pin molex to turn it into 2, then use those 2 for the pci-e convertor.

Thanks heaps.

Also if someone doesn't think it will work or is unsafe are there any Sata power to molex convertors (not molex to sata)

THANKS!

Wire it wrong, you'll probably fry it or something

658985 2008-04-15 07:13:00 Bad call Capt!, the PSU HAS to have enough amps on the 12v rail to power that card, which if the one in your sig, is I think from memory, around 26a. Please check the side of the PSU, it should state how many amps are available on each rail! SolMiester (139)
658986 2008-04-15 07:15:00 No I don't have that computer, That's old =\. Why is it so bad to use a molex splitter =\. CaptainVincent (76)
658987 2008-04-15 07:20:00 Because the pci-e 6pin connector is for 75w, molex is half that, 8 pin pci-e is 150w!.

If you try to power the card with not enough amperage, you may damage your expensive equipment, including motherboard!

658988 2008-04-15 07:26:00 So if I get an adapter, won't the PSU simply just be sending more power to power the molex splitter so both adapted molex's are the normal watts? If i'm getting this all wrong does anyone have a link to a sata to molex (not molex to sata) power connector I saw yesterday but can't find the link. Thanks. CaptainVincent (76)
658989 2008-04-15 07:44:00 I would get a PSU with the right connections for the card.

Wire it wrong, you'll probably fry it or something Good advice - personally I'd do the same.

While you can "fiddle" with the power at the end of the day get one thing wrong and "POOF" !!

now - New board, Graphic Card - god knows what else - OR New Correct power supply <<<< Correct PSU cheaper choice.

However molex are not designed to power pci-e, if you had separate rails and took a molex from each separate rail to create the pci-e power connector, that would be different if the psu had enough amperage, but you have yet to state the PSU ouput.

Are your PC components worth the risk?

658991 2008-04-15 08:43:00 do it once and do it right.

spend $100 to save $1500.

658992 2008-04-15 11:31:00 Oh okay. Would anyone be able to give me a link to a sata power to molex convertor then. Thanks. CaptainVincent (76)
