Just a quick question if anyone would be kind enough to answer it, just bought a new power supply and am getting another graphics card for crossfire. The thing is the graphics cards require 2 power leads, but the power supply only has 2 pci express sockets on it. There are however loads of 6 pin IDE sockets available on the power supply can I use those to power the second card when I get it?
Graphics card installation help.

Registered 8 years agoIm not an expert on this, but I think you can buy converters for some types of power lead.
If you have the link to the card and power supply I'm sure that would help someone tell you. -

Registered 11 years agoYou can indeed get convertors (Amazon has plenty of sellers), you sure your PSU is up to the task of running two cards in the first place as the beefier PSUs normally have extra PCI-E leads from the get go?This space left intentionally blank.

Registered 2 years ago@Whizzo it says its crossfire ready thats why I bought it, the thing is the ports for the pci express cards are the same as the other ports on the power supply just blue and not red. If I put the graphics card cable into one of the red ports to see if it will work is there a chance I could fry my graphics card? -

Registered 4 years agoDo you have the details of which psu and which cards you want to crossfire?
Check the 12v rails, because a gpu with enough grunt normally has the needed leads. It might be crossfire ready, in that it can handle two low end cards remember it is not just the high end cards.Known as 'Sharzam' in 98.5% of games

Registered 11 years agoWhat PSU is it? If it's says it's Crossfire ready I would think you'd be okay, I assume it's a modular power supply so the colour coding is probably just so you can identify which cable is powering what card.This space left intentionally blank.

If the website review of those cards I checked is to believed, it will be touch and go for power at 256watts/card at max load, if you have a couple of fans, two 3.5 HDDs and one or Two DVD/Blu-ray drives. At maximum load, lets assume just from motherboard with CPU and GPUs you are pulling 600watts. The Psu has to be providing nearly perfect power two provide enough for everything else.
Converting other sockets for GPU is also not considered as power efficient (iirc) and so I would say you are 200watts adrift for a stable system using PCIexpress power converters.
Anyone, that give you this advice

Is a cunt. 2 bluray drives? What, for 3D?

Registered 11 years agoIt's fine, seriously. It'll chug along on 50watts less quite happily meaning you've got plenty of room to add another hdd along the way.+1 / Like / Tweet this post

Yes it needs to be sustained also, but that wasn't the question being asked by OP.
You need plenty of headroom with PSU for a stable system. Xbox360, PS3 and WiiU all have PSU that are rated much higher than the power they draw at maximum load. It is like music, you need large speakers (maybe even capable of 4times) what you output at for great sound. -

Yeah because the warnings of under powering GPUs potentially doing damage is just for giggles by the manufacturers is it? -

Registered 4 years agoPersonally I always use a psu with much more power than I need.
Not for a technical reason but just because I like to able to chuck anything I like in to it without thinking about it. I have a corsair 850w gold modular psu, just because I might fancy chucking in more drives and/or gpu.
But as it stands right now it is total overkill.Known as 'Sharzam' in 98.5% of games

And who are you, just out of interest? Is this really your wheelhouse?
Someone asking this question, is someone clearly in need of being cautious. Just like cowboy dirtbox should be, given his own late education on computing, judging by his wifi plea for help in 2006. -

Registered 11 years agoAnd I've still forgotten more than you'll ever know. Like for example the fact that every PSU is marked at anything from 50 to 100 watts less than they're safely capable of.

Safety isn't equal to capable. As it doesn't necessarily mean working correctly. Safety is about risk to consumer and surroundings, not safety for the defenceless little devices.
The safety they build in is to compensate for the bad advice you give. -

Can you please post everything you have in your system, and we will calculate it using a power calculator and see what it says. -
