Hello i need to get new GPU for my pc, currently choosing between HD 6870 and GTX 560, but i'm not sure if my PSU can handle this cards.

my configuration -

CPU: Core 2 QUAD 2.5GHz, Q8300, 1333Mhz, 4Mb

MainBoard: g41m-es2l, s.775,G41chipset,FSB 1066/800,1333 DUAL RAM DDRAM II 533/667, PCI Expressx16

RAM: 2048 DDRAM II /800Mhz/

PSU: Xilence 500W

Hi

If your PSU is the XQ 500W then it'll be fine, if its the R3 then You'll have to have a look at the label on the PSU for us and look for the wattage under the +12V rails(s).

it's actually a 550w PSU, i have this one - http://www.xilence.net/en/products/power-supplies/red-wing-series/product/241287.html

It's only 1 x 6PIN PCI-E there, and as i know both of this cards require
2 x 6PIN PCI-E, can i solve this problem somehow ?

Yeah its an R3, the specs list the +12V rails amperage but not wattage which is really important to know.

You can use a molex to 6 pin adapter like this:

Like I said before you can check the +12V wattage on the label of the PSU.

Was able to see only this http://i.imgur.com/fDyLl.jpg
Don't think there is more information on the PSU. 8(

Wow, that's annoying, I expect it would be fine, but I would personally contact Xilence to find out the wattage dedicated to the +12V rails. Just to be on the safe side.

Ok, big thanks for help omgitzfatal ! I will try to find more info about that PSU, but how much wattage i need ?

 

[Rustyy117]

The higher the quality of PSU the more wattage will be available to the +12V rail(s), In your case I would say you'll want atleast 400W available for the +12V rails.
