XFX HD 4890 question

i recently bought an XFX ATI Radeon HD 4890 and when i was installing it, i connected the two 6pin power connectors to the PSU(550watt) using the 4 to 6pin power cable converter. everything was fine until i looked in the quick installation guide and i noticed it said that XFX cards do not support the use of two 4pin to one 6pin power cable converter for this graphics card. which is also very confusing because i got 2 power converters in the box.

thanks in advance for replies, much appreciated

  1. Is the PC working fine?
  2. i havent booted it yet because all the power converters left me no power for the harddrive lol.. i just need to get 2 power splitters
  3. What brand is your PSU? model?
  4. its a very cheap one, it may only be south african.. Black Power LPG6-550W
  5. Using the 4pin molex to 6 pin PCI-E should be no problem, people do it ALL the time.

    Did your PSU have 1 PCI-E to use of did you have to use (4) 4-pins to connect the adapters?

    Your comment worries me about your PSU, what are the specs on it?
  6. I never like 4pin to 6pin connector.
    Anyway, u must try it first whether your system can be stable or not, get 2 power splitters and let see where it goes...
  7. yaa,, mike row(lol), my comment about my own PSU also worries me a bit. when i come into some more money i will upgrade to a coolermaster 600watt(or what would u reccomend?). and my PSU only has- 1 motherboard power connector, one 4-pin CPU power connect, 5 or so 4-pin molex connectors, and a stupid floppy power thing

    and i have no idea about specs on PSU as it came with no manuel. (there is a large sticker on the side of the PSU with a whole bunch of readings on it, not sure what its for
  8. and (wa1) how would i measure my GPU stability???
  9. stable here means that if your computer can boot up and work perfectly... :)
    so u must powered up your system so we can know whether it work or fail, so get that spitters for your hard drive...

    Are you located in the US or another country?

    Here are some good deals I saw on Newegg, these suggestions are based on your current system. The 550W would be best for future upgrades as it has (2) 25A rails, the 500W has (2) 18A rails:
    OCZ 500W $60+free shipping +$20MIR = $40 after MIR: http://www.newegg.com/Product/Product.aspx?Item=N82E16817341016
    OCZ 550W $70+$6 shipping+ $25MIR =$51 after MIR: http://www.newegg.com/Product/Product.aspx?Item=N82E16817341022
  11. very nice but i live in south africa. (i only was able to buy the 4890 off amazon because my cousin was in the US for christmas...
    i can get either PSU here in SA but it will cost me a little more...

    the reason why i suggested coolermaster was because i can get CM products at cost price

    Oh really, then go with Coolermaster. I would recommend the eXtreme Power Plus 550 or 600

    It most likely means if you call them they will suggest that you do not use them. You won't void the warranty, they won't know you are using it or not. The adapters are used quite often. Mostly when people have only 1 PCI-E connector and need a 2nd. Don't worry about it. The warranties are also "modder friendly" so you can overclock and replace the cooler if you want and it is still covered. You just have to have the original cooler if you send it in.

    haha not in the least. I just use common sense, what I read, and personal experience. If I give my opinion I say it is only my opinion and let people decide on their own. Otherwise I try to give some sort of basis on my comments with links and what not.
  18. cool cool jay..

    i finally found a way to get the card working but when i booted up, BIOS posted and everything, then the windows XP was loading up and there was horizontal lines across the screen as well as the screen was flickering.. once i got into my desktop the screen just went blank, i know the gfx card was giving some sort of a signal through to the screen because the screen picked it up.

    anyway, i then switched off and decided to remove the graphics card and put my old one back in(x1600 with latest catalyst driver). when i removed the 4890 it was verrrryyy hot(dont know exactly what temp was, as i was unable to run any sort of program), but it was hot to the touch. could it have overheated when XP was booting up?

    could u maybe give some advice and a few thoughts as to what i should do.

    thanks
  19. Those cards DO get very hot. I had (2) 4870's in crossfire before my 5870 and had heat issues. The top card would hit 100C and then crash. The one day I was troublshooting and powered off after a crash and went to grab the card and burned my fingers. Just to give you an idea of how hot they get. They do get pretty warn. At bootup they start at 100% I believe. You could be having a power issue if they it does not boot.
  20. awe haha.. what did u do about it okini?
  21. o my sack!! i also got my 4890 a week ago and we have same problem...!!??? i just need to get my new PSU this weekend or next week and then i'l be up and running

    I tried 1920x1080 with 2xAA at very high settings on Warhead with my 4890 and I got like 23 FPS average haha, not good. That card cant handle that I dont think. But tell you what. Search Crysis ultra high settings mod and download that and it makes the game look a little better than very high but you get like no performance hit. I am running it with the ultra high settings @ 1080 with 2xAA and stay right around 30 FPS which is very playable in crysis. And I really cant help you on the PSU, sorry.
  25. thanks bru
  26. Whats your maximum you can spend on a new PSU?
  27. R650.00 which is like $85
  28. Oh okay, I never caught that you werent from the US until now. Go with the Coolermaster then if you can get it at cost.
  29. yea i also thought so but coolermaster- 600watt vs "MAX 730W Ver2 SATA Gaming Power Supply"...?? thats all the info i get from supplier.. what do u think
