Help installing usb 3 pci

[Tommyboy70]

Hi

I bought a Rocketfish usb 3.0 card and am having trouble finding out what type of adapter i need to buy

the model number is RF-P2USB3 and i am trying to install it in a Dell XPS 8300

It needs a 4-pin floppy power plug

i looked on line yesterday but couldn't figure out exactly what i needed

A link to exactly what i need would be great

thanks

What you really want is a cable that plugs into a sata power connector and splits to a sata power connector (so you can recconect the drive you unpluugged) and a floppy power connector (for your USB3 card) with the floppy connector on a relatively long wire so it will reach over from where the drives are to where the card is. Unfortunately i've never seen such a cable for sale . You could make a custom cable but the fact you are asking this question makes me suspect doing so is beyond what you want to/are able to do.

So I think using two adaptors is the answer, one to split the sata connector into a SATA and a molex and the other to turn the molex into a floppy connector. This should also give you the length you need e.g.

I think the combined length of 17 inches (5 inches in the splitter and 12 in the adaptor) should be sufficient to reach from the drives to your card but please measure before buying and if nessacery select a longer option for the molex to floppy adaptor.

Something about a USB 3 card requiring a floppy power connector seems a little retarded. I guess it's a PCI card so the odds of it going into an oldish system is pretty good, but why not just a molex?

Personally, I would not have purchased that card at all (especially from Best Buy): Rocketfish is one of Best Buy's "house brands" - and Best Buy already charges exhorbitant prices on add-in expansion cards and accessories. And the $60 plus tax price for that card is downright ridiculous, IMHO.

It's PCI-Express, why doesn't it just draw power through the PCI-E slot? Whoever is the purchasing agent doesn't know what they are doing.

Yea i wish i didn't buy it too,. hopefully i can return it

Thanks for the suggestions

yes, return it. if you really need one, monoprice sells them pretty cheap, iirc, but you will still need supplemental power - but you can get the adapter from monoprice, too, lol.

According to pinouts.ru PCIe slots don't have a 5V power line. So any card that needs 5V has to have either a supplementry power connector or some kind of voltage regulator. Every USB3 PCIe card i've seen required external power, I guess an extra connector is cheaper than a 2A buck converter.

While a floppy style connector wouldn't have been my first choice I don't see anything particually wrong with it.

I haven't seen a fdd connector in years.
