PSU and 6750

Hi im buying a new video card, probly the 6750 but maby the 6670 and im wondering if this PSU i got will handle them. Im using it right now with a 9600 GSO 512 ram, i3 2120, 4 gig ram, h61 motherboard. i dont know much about power supplys so any help would be cool, ive heard the 6670 doesnt take to much watts to run but im not sure if the 6750 would run.


this is the PSU:

http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1361838&CatId=1078

DiabloTek PSDA400 DA Series Power Supply - ATX, 400-Watt, 2x 80mm Fan, 78% Efficient, Silver, SATA Ready


Ive also got this other PSU thats 550w but its from a few years back not sure if it would be better. but still curious if this would be good enough.

More about 6750
  1. It's not a good brand, if you can, go with better brands mate.

    Say this:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817371045

    It'll be more future proof, bigger upgradebility and less chance of failing.

    Otherwise it's probably enough. And I just simply could not understand on how you have 512MB of RAM? Upgrade it? If you put a 6750 it's not going to make any sense, a computer with 1GB of Video ram with only 512MB of RAM DIMMs system memory.

    Oh my bad, i meant 512 ram on my Video card, i have 4gigs of ram.


    and ya i know its not great it came in a barebone deal i got im just wondering if it will work with the 6750, ill upgrade to a better one sometime later.
  3. Also i just checked the PSU in my old computer thats not being used and its a Optimax titan power ATX-550PS.

    wich would be better?
  4. Sorry not noticing there (is it fix'd or I'm just not noticing?) Apologize mate.

    I think the Diablotek one is a bit better, because the Optimax one is too old. Anyway, if there is no problems it will probably just work fine.
  5. Both your PSU's are no good or at least I would not trust them on the new cards if you get them. Another question a year from now are you going to upgrade your card again. If so maybe you should get into a higher PSU now.

    I would say a 500w It would give you room and you wouldn't have to worry and If you upgraded your CPU with another card then you have it covered. You should be able to up grade your CPU to a i5 on the same MOBO.

    All that is just food for thought. And here are some links to the PSU's. I do wish you the best of luck

    are you talking about higher end cards when you say that or do you mean the 6670 and the 6750? casue im not going to upgrade for awhile, definitely not within a year i just bought this computer(well expect for the graphics card, i just am using the one from my old comp) and when i do upgrade ill worry about getting a New PSU then.


    But ya, i mean if i have to get a new PSU then i guess i will but id rather not and i went on Newegg power supply calculator and when i put all my computer specs in with my 9600 GSO card, i got like 332W but when i switched the card to a 6750 it said it would use only 327W and for the 6670 like 298W.

    so does that mean my 9600 is harder on the PSU then these newer cards?

    Also about the PSU, are either of these be better.

    They also have that antec vp 450 you linked for the same price,at futureshop and i got some gift cards there and id rather use them on the power supply casue they dont have to many graphics cards.

    So out of those 3 wich you think is best?
  8. I would get the Antec, but that is just my opinion. Whether you copy me or no it's up to you :D.
  9. Buy the Antec Neo Eco. I have 1, it can power a 6850 with a Core 2 Quad. Antec rates their PSU's as sustained wattage, not max. 400w Antec is like a 550w crappo brand (such as Diablotek)
  10. this would be better then both of them that you mention and if u can afford it just go for it.

    or

    http://www.newegg.ca/Product/Product.aspx?Item=N82E16817371020

    justt cost little bit more and buy this for better quality and performance.

    Cool thanks for all the asnwers i think ima go with he antec 450. now i just need to decide on a card.
  12. with that PSU the safe way would be 6670.

    you dont think a 6750 would run on that antec vp -450? casue if im upgrading the PSU i probly gonna wanna get somethin better than a 6670.
  14. It would run a 6750. It has 36A on the 12v.
  15. yes it would run fine i was wrong :)

    You have to love those calculators. The difference between a good PSU and a bad one is how constant the amps are on the 12v rail. A lot of PSU's will show 500w peak power or it will show total power.

    In any case you want constant amps that way your card and your CPU will be feed the proper amps all the time. Yes there are some PSU's that are like 300w and can push a 6750 just because they have enough amps on the 12v rail.

    Some of the newer cards are using less power to run. But the calculators are lookin at everything you are running. If you have a rig like mine you have to count extra for the fans all the lights, the temp and fan monitor/controller.

    You have to count on OC'ing plus the GPU's when playing games they tend to draw constant load amps for long and short periods of time. That is why you want a PSU that gives constant wattage/amps. And the brand names we have all given are those type of PSU's.

    Ok thanks for the help but about the bolded part, i dont think my computer has many extra fans(it might not have a main on im not sure), and it doesnt have lights its prity basic when i bought i was trying to build a good cheap computer so i didnt pay much for the case and its actually not as bad as i thought but i was wondering, if i got this antec 450vp and got a 6750 or im actually thinking of going a bit higher maby a GTX 550 ti. ive heard the 6750 would run but what about the GTX 550 im just curious cause theres a lot of deals im seeing with cards in similar quailty/prices and wanna make sure on the PSU but also would i need to add fans to a computer like this?

    this is my case:http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=7108886&CatId=1844

    intel motherboard h61wwb3
    i3-2120
    4gig ram
    160 gig hard drive(im gonna get a bigger one soon.
    and say a 550GTX ti/6750/6770/6790+
    antec vp450 PSU


    would that run ok together?

    Edit: Also i never overclock anything and ive heard i3 dont overclock well so i wont need worry about that.
  18. Yes 6770 and under, 550 ti and under you won't have any problem. I don't know about 6790. The reason for all my fan's is for cooling and air flow so everything runs cool.
