Can XFX Radeon HD 5770 run without external power

[mohitk593]

Hi Guys,

I need your help.

I was using XFX HD 5670 and got damaged in warranty so XFX gave me a HD 5770 graphics card.
As you all know 5670 doesn't require any external power but 5770 do have a 6 pin slot.

I have read some where that 5770 and 6770 can run without using external power.
They can draw the power itself from PCI-e slot. Is it rue or not ???

Please suggest me whether they can run without using external power or not ??

Also if they do require external power. I have a local brand (intex) 450W PSU, can I use it by purchasing 6 pin to 4 pin cable.

PC Specs:
Intel i3 2120.
Gigabyte B75M-D3H
1 TB seagate HDD


Guys please advice asap.
Thanks

No it's not true you will have to use a 6 pin vga power plug with it you will not get a picture at all with out the extra power from the vga plug the pci e can only feed 75 watt's max that's it.

Okay what do u say will my current PSU handle this card by just purchasing a molex 6 pin to 4 pin ??

 

[kitsunestarwind]

Yeah you will be fine using a 4pin to 6pin adapter with that PSU

 

[megahurtz]

Well the wattage is correct and the amps also are fine but if it's a cheap brand it may not work for long as long as you don't overclock it you should be fine.

Here's a link to the product page.

Yes, Thanks I have already looking into that page and AMD specify that it requires only 75W power using 6 pins.

Also my card is this one : http://xfxforce.com/en-gb/Products/Graphics-Cards/AMD/ATI-Radeon-HD-5000/ATI-Radeon-HD-5770/HD-577X-ZHLC.aspx

and yeah will change my PSU in a month or two, but I just want to be sure that the current PSU will handle the load and will not get blown up.


Thank you all for your quick replies, also could you pls say something about this card. How is it for medium gaming.

the x770 (so 5770, 6770, 7770) series is meant for medium gaming, so don't worry =)

You'll be able to game a little better than you used to.
