Will a 7850 work with a Powercooler 500watts?

Hello community, i am planning to buy a new graphics card, and i have the following computer:

CPU AMD Phenom II 955 BE
RAM 2x4GB Kingston 1333Mhz
AMD Sapphire 5670 512mb
Mother Gigabyte GA-M68MT-D3
PSU Powercooler 500watts

I am between AMD: 7770, 6850 or 7850 (which brings some free games in promo i think)

I want to know if the 7850 fits well with the PSU and that Motherboard

thanks you

  1. YES! 500W PSU is enough for a power efficient card like 7850. It will fit into your Mobo as well as your budget i guess.
  2. yes no problem there
  3. 500W is plenty, but the PSU may be of inferior quality.
  4. sakkura, good call.

    whats the brand and model of the psu?
  5. I couldn't find the Powercooler website or more information about them, but those are real 500 watts, it costed way more than a generic PSU.

    Can you tell us the amperage ratings from the 3.3V, 5V, and 12V rails?

    Typical. That's not really a good 500W PSU, it's more of a 400W unit. It could still do the trick, but there's much less margin for error. Since they're somewhat dishonest about labeling and are not a reputable brand, the red flags are beginning to pile up.

    So, i won't be able to use a 7850 and neither a 6850? And what about a 7770? It consumes much less watts.

    I kind of agree. I wouldn't trust this PSU so much.

    Agusfn: Even if you think you paid more for it, beware of some PSUs maker, they don't always deliver power as advertised. As Sakkura pointed out, I wouldn't be too surprised if you can't push it past 400 Watt or something. It could be limit or risky to run a 7850. In the future try to get a brand with a solid reputation like: Antec, Corsair, Seasonic, etc...

    You MIGHT be able to run a 7770 but I would say a 7750 would be closer to safe. You should buy a new powersupply as soon as possible preferably from Seasonic, Corsair, XFX, or Antec.
  12. yup.. the powercooler you have is made by topower. a "do not buy" brand...the gpu's you want need 20-30 amps on the 12v rail. your psu is not sufficient
  13. Allright, a 7770 uses 80 watts, and a 7850 130 watts, i shouldn't have problems with a 7770, will i?
  14. Get a new psu - one that can handle an HD7850. They are not that expensive - where do you normally buy?

    There are limitations with dollar currency and imports, so everything imported is pretty much expensive than in the US.

    I will be satisfied as long as i can play in 1680x1050 with high graphics and 40-50 fps games like battlefield or far cry 3, and i don't have a big budget, only 1000-1500 ARS.
  16. youll need a new ps.

    link me to the powersupply section this sites confusing
  17. While it is more of a 380-400 watt power supply. This may simply be due to its age. Older power supplies had more on the lower rails.

    Now days its is all about the 12 volt rail.

    Your power supply has 28 amps. IF it can deliver, then a 7850 would not be much of an issue, but because powercolor is not known for quality, I can see being more cautious.

    You do not need a high wattage power supply for a system with that card, just you want QUALITY.

    where do you see 28A? i only see 20 and 17
  19. ARICH5 said:

    It can supply a combined 340W on the 12V rails, which works out to 28.3A.

    this is probably the best brand i can find on that website. it has 50A on the 12V rail which should be plenty. Cooler Master isn't the best but this one (or one very similar) has fairly good reviews on newegg.
  23. yes. but why would u bring me to this section, are you insisting im a noob? :D
  24. i asked if you would kindly chime in with your opinion is all. thank you.
  25. i did. i was speaking to him. not u.
  26. ARICH5 said:

    With multi rail power supplies, you have a combined. It is not just adding, and is the number you use to describe 12 volt power.

    22A or 22 x 12 = 264 watts. and Yes, I run a GTX 650 ti on it :p


    288 watts or 288/12 = 24 amps

  28. ok...so he has the wattage and the amperage...would you trust th OP's powercolor?
  29. yes i agree about the psu requirements inuke. but its always better to have more than just the exact requirements.

    yes powercolour is fine.
  30. ARICH5 said:

    It's not Powercolor, it's Powercooler. I would *probably* trust a Powercolor PSU, but Powercooler...

    LOL I wouldn't trust either one.
  32. whats ur exact power model. well powercolour makes alright ps. powercooler sounds generic
  33. its above..8th post

    They aren't generic. His is a Topower which isn't made very well. http://www.tomshardware.com/reviews/power-supply-oem-manufacturer,2913-8.html
  35. i guess it will do. but still not high quality
  36. So.. W¡ll a 7770 work without problems with my PSU?
  37. yes.

    thats right it will work :D
  38. i still wouldnt say "without problems"....try it and dont say we didnt warn u :)
  39. My current gpu consumes 61 watts and works perfectly, never had a problem, the 7770 consumes 19 watts more. I don't see a big difference.
  40. according to tomshardwares old review of the 5670, it consumes 76 tested watts under full load.

    according to tomshardares newer review of the 7850, it consumes 99 test watts under full load.

    23 watts give or take 10% error so say 26 watts, i dont see this being a problem as its not that much of a jump. You could go to home depot and buy one of those watt meters that you plug into the wall and then plug your current computer system into it and see what the total draw is, then return it.
  41. I would keep the watt meter :) they are useful for all kinds of things.

    Funny thing is my I7 2600K @ 4.4 with a 5870 idles at about 80 or so watts and games under 300watts.

    Its not about wattage as much as quality of the power(many cheaper units have too much ripple or voltage that falls out of spec) and how much of it is on the 12 volt rail.

    I am not lying when I say that the 300 watt FSP I showed above runs a 650ti without ANY issues(under 150 watts[as per my APC ups] on most games, but I am almost sure I can hit close to 200 with OCCT psu test), but it is a very power efficient system as well.

    :) I do not think the cpu ever hits full load, so again it can take more.


    It is hard to yes or no a power supply that I have never tested.
  42. i prefer recommanding abit more than exact power needs.

    always good for headroom and most people dont own a killa-watt meter

    Yeah, In general, about 2x the common load of a system gives max efficiency.

    So a gaming system that games at 250-300 is best served with a quality 500-600 watt unit(PSU's tend to rech top efficiency about 50-60% of max load).

    My media centers gaming load is about 150(peak and lower most of the time) watts so 300 works well and the power supply is decently efficient at the lower idle loads(honestly the load this[30-60watts] system will spend most of its life at). All the parts of that system had been picked to fit within the power supply limits(with room to spare), not the other way around.

  45. To dont open another thread , this PSU works fine with a Radeon 6450 1GB DDR3 ?
