Hi I started to build my new pc and I ran into bit of problem.

I currently have XFX ATI HD 4890 and I also have Thermaltake PurePower 500W for my PSU.
The problem is, I didn't realized that 4890 needs both 6 pin pci-e connector and 8 pin pci-e and my power supply has only one 6 pin pci-e outlet.

I couldn't refund my PSU because I bought it couple weeks ago, when they had huge sale on Thermaltake psu so I'm kind of stuck.

My graphic card came with 4 pin to 6 pin adapter (I think 6 pin connector is 6 pin pci-e connector) so what I thinking of doing is to buy 6 pin pci-e to 8 pin pci-e adapter seperately so I can have both 6 pin pci-e connector and 8 pci-e connector.

Do you think it works? Did anyone tried it yet?

Thanks

Please help

As long as you can get an 8 pin connector it will work fine. You can either do 6-> 8 or molex -> 8.

I think the 4890 that has 6 pin and 8 pin connectors has a PSU minimum requirement of 550W. You need to consider buying another PSU or downgrading your video card.

 

Found this on the XFX page http://www.xfxforce.com/en-us/prod [...] 890.aspx#2

No affense but research shoulda been done a bit before you bought that card. Those cards are power hungry, as are most high end cards. So i think you should strongly consider getting atleast a 600watt psu to be safe. PSU's are the one thing u really cant afford to cheap out with on ur pc. Yes you could run an adaptor but id expect problems. I seriously think you should break the bank a bit and go atleast 600 watt.. just an opinion. Or take a chance and go with the convertors but you might end up spending the money and it stil might not work.

you should get a psu of at least 800 watts or more I had blown like 4 corsair and antec with the 4870 1 gig gddr5

lol now I am running stable with a 1250 watts from cooler master.

enjoy.

Stop giving dumb advice. This is the second time you've posted this.

Well it's my fault that I didn't research deeply into what kind of connectors does 4890 have but I have read countless reviews and videos for this video card before I purchase this.

Most experts said if you have descent psu, 500w is more than enough for 4890 unless you are doing oc, which I'm not planning to do.

Thats bad advice.

No need to go that overkill with a PSU.

Like others said, that's just ridiculous. An 800W Corsair would have no problem with a 4870. Tbh a 1250 Cooler Master is probably not a substantial amount better than the 850W Corsair.
