New computer builder needs immediate help!

post #1 of 38
Thread Starter 
Hello community,

I am a fairly noob builder and have several questions. I just upgraded to a 5870 Sapphire eyefinity gpu, but when connecting it to my 850 watt psu, I realized there was only one 6-pin (pci-e allotted) power connector. I have no spare connectors from the psu to the gpu other than the pci-e one. So I connected the 8 pin power socket of the gpu to a psu connector that is connected to my hard drive. Is this setup safe and viable? Or am I sharing power that is sent to both my hard drive and gpu? I'm sorry if what I say doesn't make much sense, so please ask for further clarification and I will respond with as much coherence as possible. Also, I ran a 3dmark vantage benchmark to result with a 10k performance setup score. This score is unbelievably low compared to the average of 17k. I am in desperate need of explanation as to why my score was so low?

-Sincerely,
Kero

it might help if we had a bit more info about your setup.
what brand/model of PSU is it?

It is IMPOSSIBLE to use the cable that powers your hard drive to also power your Graphics card.

this should be what's powering your card


This should be what's powering your Hard Drive.


Are you saying that you are somehow interchanging them???

This is also an older power connector for the hard drive


And if it works, sure. Hard drives don't use THAT much power.

Sorry for the confusion, so the hard drive connector in the 2nd pic is the one that is connected to my hard drive. However it is a split wire with multiple ports just as the one in the third picture. I connected the 8-pin power connector from the 5870 to one of the ports on the split hard drive connector.

yeah, what max_it said hahaha.
that PSU should have heaps of PCI power cords. hx-850 is a modular isnt it? you should have got more leads with the power supply

EDIT: I think your using the 8-pin EATX

If you mean that the two connectors are coming off of the same group of wires, then it is fine.
Usually nowadays there isn't 1 connector on each group of wires anymore.

I believe he's saying in the OP, that he's using an adapter like this to power his GPU.



As the Sapphire 5870 2GB Eyefinity 6 cards come with one nearly identical to this (except with an 8pin pci-e connector). To answer your question Kerotero, it's fine to use the adapter. But you should be using it off 2 different molex (the psu's hdd connector) on seperate lines.

That is not the source of your problem though, I fear. If you could please fill in your system specs in the "User CP" it would be very helpful for helping us troubleshoot your issues.
