ChuckFinly Posted February 9, 2012 Share Posted February 9, 2012 (edited) Can this power supply with its 12V rail rating run an AMD Radeon HD 6850 without any overclocking? Other system specs: Processor: AMD Phenom II X4 BE (3.2GHZ)RAM: 2 X 4 GB DDR2 G-Skill 1066MHZASUS M4N82 Deluxe MotherboardVideo Card: (potentially) mentioned above If not than could I run an AMD Radeon HD 6790? Thank you for your time. Edited February 9, 2012 by ChuckFinly Link to comment Share on other sites More sharing options...
hoofhearted4 Posted February 9, 2012 Share Posted February 9, 2012 why do you want a cheap PSU. i highly recommend against it Link to comment Share on other sites More sharing options...
Paxan_1 Posted February 9, 2012 Share Posted February 9, 2012 Hi, i wouldn't buy this part of electric engineer "art". Well, please have a look into the specifications yourself, the output values are the important ones. They write: +3.3V@38A, +5V@40A, +12V@25A, [email protected], [email protected]. For a modern computer the 12V rail is the important one, for this psu it means 12V with 25A, Adam Riese would tell is that these are 300W. Because i'm not sure how much a radeon 6870 needs i can't say 300W is to less for it. What i know is you cant run a 6790 with it. To run a radeon 6790 i would go for at least 500W. If you go searching for a psu i would suggest to mind the following points:1. check the wattage of the psu by calculating it yourself, the 12V rail is the important one. Wattage is amount of voltage multiplied with the amount of ampere of the rail. 2. a modern psu should have at least two different 12V rails, this is because it is better for power consuming graphic cards to have their own rail And a little advice, the psu is the part that is providing the energy for your whole rig, do yourself a favour and dont buy the cheapest one ;) Hope i could help you, Sarah Link to comment Share on other sites More sharing options...
Illiad86 Posted February 9, 2012 Share Posted February 9, 2012 I'd totally avoid that brand, they break quick. We bought my cousin a cheap case for his computer and it came with that brand of power supply. Put everything together, turned it on, *pop sizzle*....dead. First turn on and it died lol. Never buy a cheap one, it's never worth it. Link to comment Share on other sites More sharing options...
bben46 Posted February 9, 2012 Share Posted February 9, 2012 Did you read the feedback? Nearly 20% gave it one egg, and less than 50% gave 5. That's a bad ratio to bet your system on. one out of five had a serious problem, and less than half of the people that bought it liked it. :down: Link to comment Share on other sites More sharing options...
Pronam Posted February 9, 2012 Share Posted February 9, 2012 A cheap power supply can ruin your whole system, don't do it. These types of PSU are prone to build failures, heat failures and peak failures and their lifespan is very short. It will cost you a lot of money on the long run and might damage your video card or any other parts whenever it drops on output. Link to comment Share on other sites More sharing options...
ChuckFinly Posted February 10, 2012 Author Share Posted February 10, 2012 (edited) Thanks for your responses.Not be rude, but none of you answered my question. To be more specific to my question, since that PSU is out of my thinking process now, what are the Amp/Current requirements for a 6790 or 6850? I think the 6850 has a TDP of 130 or so watts, but without knowing the rail requirements, that number is almost useless. I'm am the kind of person that would buy a simple 450w power supply to run the system, and have a generic 200-250w psu to run just the card, but if the Amp/Current requirements are not met by that generic, than it doesn't matter and I'm wasting my time. A little better? Edited February 10, 2012 by ChuckFinly Link to comment Share on other sites More sharing options...
Paxan_1 Posted February 10, 2012 Share Posted February 10, 2012 Hi, well, short answer, for a 6850 you will need at least 400W for your setting, that means the first psu wouldnt make it (300W). The Rosewill Green Series RG630-S12 630W will do it, because it has 50A on the 12Vrail, makes 600W. This one would do it too: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182199 Sarah Link to comment Share on other sites More sharing options...
