Quick question

I need to get a molex to 6pin PCI-E power converter but I have noticed that there are two types!! :confused:

One uses a single molex connector and the other a pair - what is the best one to choose??

The graphics card I am using is an HD3870 512MB GDDR4.

Do you mean a Y-spliter? one molex to two pci-e 6 pins - Shouldn't make any difference.

The converters I have seen are either a single molex to one PCI-E power connector or a pair of molex cables to a pair of PCI-E power connectors.

I know the two molex version will give you more power but TBH it means one less molex available.

You should be fine with the single molex as that isnt the most powerful of cards out there

The single for that card should be ok. If in future if you crossfire it or summut you can swap it out for a double

Nice looking GPU BTW

Thanks everyone for the replies!!

I am doing a mini ITX conversion of a Shuttle G2 box and the 1U PSU I am using only has three molex connectors. If I can get away with using a single molex connector each for the SATA hard disk and the graphics card it would leave one free for the IDE optical drive I hope to re-use.

the 3870 has a max power draw of about 105w so the single molex connector with the pci-e slot should provide more than enough power, i think the double ones are meant for cards that draw around 150w.

The issue is whether the psu can cope, not whether the molex plug can.
