Hi, I recently got two nvidia GTX 470 in sli. However when ever a play a high end graphics game under high settings and resolution(like metro 2033 at very high settings and 1900/1200 resolution) the computer(probably video card) start to beep. Interestingly when a lower settings and resolution the beeps generally stop or only happen at times when higher graphics processing is required like going through fog,smoke or explosions and after passing fog smoke or explosions the beep stops. In my opinion the problem is not temperature related because the cards are quite cold event at heavy load(around 85 C which is cold for nvidia based cards) also ı believe it is not cpu related because ı have been using that cpu for quite a long time without any problems(and the problem stated with the new video cards). I think my problem is related to my power supply ,which is 750watts(and ı have many extra components like liquid cooling and case lights). I think 750 watts cannot supply enough power for 470 sli and under heavy load, the video cards beeps to warn about power shortage. I am really interested in learning your opinions and if my PSU explanation is true or not. And if it is PSU related , how much watts i require for a 470 gtx sli. Thank You.|||Your theory is undoubtedly correct. Your supply cannot provide enough current with all the graphic options turned up. Since things seem to work with lower settings, that implies that 750 watts is (barely) enough. You can find out just how much more you need by reading the docs, but it doesn't have to be precise. Generally you don't want to run a supply at its full capacity for any length of time anyway, so while an 850-watt supply might be enough, it won't give you the headroom you need to keep the supply itself happy. So go for a 1000-watt supply, and get a good name. PC Power & Cooling used to be the best of the best, but CoolerMaster's premium line is probably as good.
Here's a link that will allow you to estimate your current needs. Take the upper range values in every case. Remember you have two PCI-E video cards.|||Yes i agree with you it could also be some form of system resources deficiency could be faults in video card prebuffer for it could be having conflicting data with game try turning off maybe or lowering those effects while maintaining the same resolution see if this helps if you want more help or further question's just send me an email on my page and ill get back to you today tomorrow.|||It's listed just about everywhere you can buy a GTX470 online about how much wattage and amps you need to run it. And if it's beeping while under load then it's obvious a PSU issue|||Your computer is overheating 85 celsius is by no standard cold
if you must know use the conversion of celsius to farenheit
185 farenheit will absolutely destroy your card if you continue to run it at that temp!!!
Add more fans or remove one of your vid cards.... your cards wont last more than a year if you dont
IT says maximum 105 for every card, but even my card at 65 celsius when it hits 75 overheats some times
It also looks like you have somewaht of power issue as well
