Is it safe?

I have a DELTA 750W psu, and i have been running a xfx gtx 260 for almost an year. recently i bought a EVGA gtx 260 ssc, and now i want to sli. I saw my PSU has four 6-pin connectors( i'm using two right now with one gtx 260) so i'm guessing its capable of sli. Is it safe to SLI with this PSU?

  1. 750w is large enough to handle both cards, the Delta brand is the question.

    Its not a card that many enthisiasts use and I have never seen a review on it. I googled and found none either. The lack of information makes it difficult to say - and I think everyone will either have the same problem or just dismiss it as not being a recognized as a quality PSU, a valid point. And since a bad PSU has the potential for damaing other components, there could be some measure of risk.

    But that said, Delta has been making car batteries and auto parts - including electrical ones for over 50 years and probably knows what they are doing. And my old Dell had a 350w Delta PSU that provided me over 5 years of good service. Dell seems to recognize the importance of good PSUs and put in strong ones because, I think, they warranty the entire system and in essence would have to pay the cost for whatever damage it did under warranty.

    Another key issue, though. is how much power it delivers to the key 12v circuit which drives the mobo and video. There should be a plate on the side of the PSU that reports amps on the 3.5, 5, and 12 amp circuits, and also the total for certain combinations. What are those amounts? And whatt is the model number? That also might help find a little more information about.

    I hate to see you shell out for another PSU if it can be avoided, but then I also don't want to advise you to do something that might risk damaging other components. But if it has enough power on the 12v circuit it might be worth trying.

    But bottom line it may be a budget decision that only you can make.
  2. delta build psu's for antec and other vendors
  3. ok rockyjohn here are PSU details:

    Model: GPS-750AB A

    A\C input: 200\240V: 5.5A

    DC output-

    3.3V- 30A
    5V - 30A
    (160Wmax)

    12v1 - 18A
    12v2 - 18A
    12v3 - 18A
    12v4 - 18A
    (648Wmax) so (727.8W max)

    -12v - .6A - 7.2W
    5VSB - 3.5A - 17.5W

    SO 750W max continous

    And its made in china
  4. Any ideas anyone? is it going to work? Or is my pc gonna burn? what is the most damage it could to?
  5. It will work fine with your system.
  6. It even saya GTX 260 supported.....

    I say it will be fine. If it bolows up blame it on shubham1401
  7. Should be okay.

    Ha ha...
    I'll take the blame...
    But don't ask for money if it blows... :pt1cable:
  9. Yes. go ahead and use it. It has plenty of power on the 12v circuit and using the model number I found that it is ATI certified for Crossfire:

    If a PSU goes bad, it is much more likely to just crash the program than cause physical damage and thus provide warning and be replaced. But it can fry a mobo = electical speaking - or a CPU, although the liklihood with a decent PSU is remote and this is a decent PSU.
  10. i SLId.

    IT WORKED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    atleast didnt blow up or anything............. thanks for ur help guys

    Now i'l try playing some games tc
  11. Just don't forget to wear your safety goggles and body armor, and to add some concrete shielding around the PC.

    Yup, another vendor

  13. But keep in mind that even though the build for other vendors, that says little about how they choose to design their own PSUs and what components they select. They undoubtably have a specific market segment they are targeting and and design their product to make a profit in those markets.

    Does anyone know what those markets are? I don't. But I suspect if it were for the descriminating user they would have provided samples to some respected reviewers and we would see those reviews show up in Google searches.

    I think Ryan's definition of "IT WORKED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" is different than mine. He got his PC to boot with an SLI setup... I'd want to see how (and if!) it gamed.
  15. Ryan...
    You can perform some burn tests/stability tests...
    If your comp survives a few hrs and the PSU doesn't gets warm then it will powe the cards well....
  16. @rodney: Its awesome for dragon age( the reason y i wanted to sli in 1st place), i can max out settings and play, but the performance is really crappy for COD6. I used to be able to play at max settings before, but now it lags whenever i try to move sideways. I thought SLI-ing would make things better

    @shubham: i didnt do those, but i have been playing games, and i think thats kind of a stability test, it survived
  17. COD6 has "a lot of bugs" I say that because just about everyone I come in contact w/ that plays COD6 on PC usually has some crippling error.

    Make sure that in whatever settings you are using that the software knows to look for a SLI configuration.

    Multiple video card configurations tend to complicate things very quickly. I would have suggested buying a GTX 295 however you already have two 260s.

    Also, on nVidia's website if you dig around you will find an up to date nTune utility, they call it system utility or whatever now but it's still there and it can help you get those GTX 260s operating at maximum in a novice overclocking environment.

    P.S. Don't search nTune directly on nVidia's website, you will most likely get the older version that's prone to a lot of crashing, a lot like what you may have seen in Independence Day.
