My power supply and HD 6850 Tags: Power Supplies HD Components Last response: July 26, 2012 7:39 AM in Components Share ochabu44 July 25, 2012 6:11:38 PM Dear forum readers, I'm planning to upgrade my HD 5670 to a HD 6850. Here's a picture of my power supply: Uploaded with ImageShack.us My question is: is my power supply good enough for this upgrade? I know a HD 7770 has a smaller TDP (a 6850 has a max TDP of 127W). But price/performance wise the 6850 is currently better. I really have no idea how to change a power supply unit... any good advice? my spec: i5-2300 4GB ddr3 ram HD 5670 GPU 2 gb TB SG barracuda green DVD r/rw More about : power supply 6850 bobusboy July 25, 2012 6:46:55 PM My buddy is running a 6850 on a stock HP PSU 300watts and he has zero issues with it. Yours should be fine. The most important thing really is the amperage on the 12v rail. I used to run 2 x crossfire 6850s on a 600watt with no issues (if you're ever considering crossfire) ochabu44 July 25, 2012 8:46:09 PM bobusboy said:My buddy is running a 6850 on a stock HP PSU 300watts and he has zero issues with it.

I used to run 2 x crossfire 6850s on a 600watt with no issues (if you're ever considering crossfire) Thanks for the quick reply! Can I assume my "amperage" is sufficient? I imagine the (6850) card will need an extra supply of power by using the 12v rail(?). Should I use the YELLOW or YELLOW/BLACK cable ?

Are you using 4 pin to 6 pin converters or does your PSU have 6 pin connectors already? Wire colour shouldn't matter, and chances are if a cheap HP PSU can do it yours will have no problem. ochabu44 July 25, 2012 9:54:37 PM I'm not familiar with connectors so I used this random picture: I checked the inside of my box and I saw a couple of free 4 pin horizontal (white) connectors and only one 6 pin (black) PCI-E. (The white ones are clearly bigger than the black connector) I read reports about 6850 videocards with two connector openings... would i be able to convert the white connectors into 6 pin ones ? bobusboy July 25, 2012 10:15:03 PM The 6850 i bought came with two 4 pin molex to 6pin power connectors (the one in the middle of your chart) So I was able to convert my extra 4 pins in to the power for my GPU. There are some revisions of the 6850 which only need one 6 pin, some with two 6 pin and i think one with a 6 and a 8 pin. bobusboy July 25, 2012 10:15:13 PM I'll be home shortly so I'll post some pics of what I'm talking about.
