Will this Work ?

June 20th, 2023

Iv got a 650w PSU and a Radeon 4870×2, Problem is – the graphics card has 2 power inputs, 1 6pin PCIe, and 1 8pin PCIe, and my PSU only has 2 6pins…
So I ordered this

Do you think it will work?
I tried to run with he 2 6pins but i just got a message at boot saying that one of the power conectors went connected.
As far as i knew the card is supposed to run wih 2 6pins – just not on full power consumption/performance (because of the layout of the 8pin a 6 pin can be placed in it)
Thanks in advance Guys

Answer #1
The Radeon 4870×2 requires MINIMUM 650W PSU, so it’s probably not capable of running it.
Answer #2
Yeah, thats why i bought a 650w, i know other people that have run it with a 650w
Answer #3
I think it will work, not promising anything tho, how much hard drives etc have you got ?
Answer #4
How does the amount of hard drives have to do with a power supply? It doesn’t take much to run a hard drive, if any.
Answer #5
@ , i meant the system as a whole, you need to take into consideration your cpu, hard drives, cd/dvd drives etc- I was only wanting a general idea of his system, sorry for not being more clearer Thanks for the critisism tho …

Check out this site

It will give you a rough idea of how big a PSU you should have
– Then worry bout whether or not the cable will work, although Im sure it will as long as you PSU is good enough
One other thing, When you get the resuts on the site, your better adding 10-20% on for long-term stability[b]
By the way, what PSU is it ?

Answer #7
I wouldn’t dare run a 4870×2 on that PSU. It’s got a total of 30A on the 12V rail which is used for both your CPU and GPU mainly. That 30A works out to be a total of 360W but you really don’t want to be using it to 100% capacity. I think a 4870×2 draws about 200-250W on full load, combine that with your CPU and you could very well end up popping your PSU and taking something with it.
I’m running a Phenom 2 quad with a GTX 280 on a 700W PSU but it has a total of 50A available on the 12V rail which is where it’s important to have it.
Unlike most PC components, the price of a PSU is almost directly proportional to how good it is. �40 for a 600W PSU would indicate sub-par components or skimping on total output. I’d spend at least �60 on a PSU if you’re going to be using a 4870×2.
Something like the below would be better than what you’re using despite being rated at 100W less.

That doesn’t mean the card draws 650W. It’s ATi’s recommended taking in to account all the other parts of your system as well.

Iv had this card for about 3 months and not been able to use it because my old PSU didnt have any PCI-E power cables, I bought a new PSU, going on word that the card would run on 2 6Pin PCI-E’s, and a 650w PSU ?
How is someone who doesnt know a lot about pc’s supposed to know all this when all Nvidia says is “minimum 650w PSU”
It’s took so long and now it still doesnt work, I’m gonna sell the card its not worth any more hassle, gonna get a normal 4870 instead of x2 version, its overkill for my sysem and Resolution anyway

I know a guy that runs two of them Crossfire on a PCP&C 750W. 650W would work fine. But whatever I guess the OP gave up already
