  1. What is your budget? A 500w PSU could handle a pretty good could handle a pretty good GPU.
  2. 300 dollar and in indian rupees 17000rs.
  3. That CM PSU may not be good for any more than 400W. I would not get anything more powerful than a HD7770 or GTX650Ti.
  4. really i shuld go with 650ti?

    this s best for that budget:

    1)Saphhire hd 7850 1gb ddr5 - rs 12500

    2)Corsair cx 500w - rs 3500

    get from local store only.hd 7850 will max games at your resolution.if you are going to upgrade monitor to 1080p then get 2gb vram gpu hd 7850 2gb @rs 13500
  6. bro i realy want to buy in the likes of gtx660 or 7870hd
  7. i want to play crysis 3 in ULTRA
  8. your psu is big problem dude.you have to get new psu!
  9. you can play crysis 3 @ultra with hd 7850 around 40-50fps
  10. i bought my psu 3 month back that y am not intrested in changing that
  11. yes i realy know that my cooler master psu is bad but i want to run games at ultra
  12. I'm sorry but you are asking for impossible things.

    So you want a very powerfull GPU, but that does not require too much power, and also are planning to stress it as much as you can.

    Aaaand want all of this with a crappy PSU (no matter when you purchased it) and with 4Gb of ram.

    Good luck, if you success let us know how!!!
  13. so,which gpu is good for me?
  14. hd 7770 will be good haaaaaaaa.i already said get hd 7850 + corsair cxv2 500w psu.

    why you are soo crazy about running crysis 3 @ultra.even at med settings crysis 3 loooooks really great!while hd 7850 will handle crysis 3 at high-ultra.
  15. You can either replace your PSU with a decent one, then get a stronger graphics card, or keep the CM and get a GTX650Ti or HD7770.
  16. And take into account that with this amount of RAM (4Gb) you will be probably paging memory (writhing things that should be into RAM to disk, to use Virtual Memory), that means poor performance.
  17. An i5-2500k with a 7850 will probably not draw more than 250 watts from the wall, with even less being delivered to the machine. I know my 3570k, 7850, 8gb, 2x7200 and 1xSSD I could get to peak at 230 watts from the wall if I benchmark everything all at once. Running games it was more in the 160-170 watt range.

    Your 7870 on that PSU will be fine. The PSU tests poorly at over 400 watts delivered, and you will be well under that.
  18. Traciatim could be right; the power use should indeed be under 400W. However, Coolermaster low quality sometimes includes missing protection circuits, and poor regulation or noise. Since it isn't a chance I am personally willing to take, I don't feel right about recommending it to others. YMMV.
  19. ok bros...my psu has only 1 6pin but 7870hd need 2 6 pin so what to do?

    You can buy an addaptor from 4-pin Molex to 6-pin PCI-E. It is a cheap cable...
  21. but is it risk as others told my psu is bad ,,,??
  22. ithink 660 is a good choise
  23. It is a risk. It is entirely possible that, if it is based on an older design, the CM has a lot of its amperage on the minor rails, and not enough on +12V to safely use an adapter. It is not something I would do with my own systems; others may be willing to do so.

    Completely agree. People used to under estimate the importance of a good PSU, until they got some fried components, or stability problems.

    I've always found what people vastly overestimate is the actual power usage of their machines to recommend crazy high PSU requirements, just like the marketing department of manufacturers want.

    Total machine usage from the wall with a 7870: 274W (Assuming 90% efficient PSU, that's delivering under 250 watts to the PC.

    http://www.anandtech.com/show/5691/the-retail-radeon-hd-7870-review-his-7870-iceq-turbo-powercolor-pcs-hd7870/4
    Total machine usage from the wall with a stock 7870: 310W (~280 delivered @ 90% )

    http://www.legitreviews.com/article/1967/11/
    Total machine usage from the wall with a stock 7870: 284W (~256 delivered @ 90% )

    All of them using rigs more powerful than his listed other components, and all well under 75% of his PSU's 408w rating on the 12v lines. Plus these are probably generous figures as their PSU's in the test boxes may not be 90% efficient.

    That last one I linked was the only one using a 2500k (OC'd to 3.8Ghz), and was also using a 1000w 80plus bronze PSU, putting it somewhere close to 80% efficient at 25% of it's rated delivery capacity, so it's probably actually delivering more like 228 watts to the machine . . .
  26. You're right about the size, but my comments concern the quality. For powering a HD7870, I'd take a 430W Antec Earthwatts (using an adapter) over a "500W" CM any day.

    Actually, my HTPC is running an i3-530 with an Earthwatts 380, and since upgrading my main machine to a 670 from the 7850, the 7850 goes in my kids machine and their 6870 is now free to go in the HTPC. I just ordered a power meter so I can test the 5770 vs the 6870 in a machine with a bigger supply to see if I can run it off the 380. That one I think is pushing it a little so I want to test it, but this set up I think is a no brainer, the 7870 will run fine.

    That's exactly what I mean. What makes a PSU good (and expensive) is not the wattage, but the components inside, the stability and the reliability. Thats why you can't compare this Coolermaster thing with, for example, a good CX430.
  29. get new dude op,qualtiy more matters.cm psu will run with pc,but the question is how long that crap psu will handle?.psu is heart of pcif anything goes wrong then it dead
  30. now my decision is that iam going to buy new psu bt which one guys i am limited on my budget.

    Well, if you want to waste some money on something you don't need that's fairly cheap at least you can grab the Corsair CX500, http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027 for 50 bucks, on sale right now.
  32. will it power 7870hd?

    What the CX500? For sure it will. So will the one you have in your machine now.
  34. yes that psu is very good and can handle upto hd 7950 easily
  35. oo thatzz gr8,,im selling my old psu and i will be buying CX500 and gtx 660 i think gtx 660 can max many games at my resolution,,,
  36. yep gtx 660 is good choice
  37. bro iam getting gigabute winforse gtx660 at 15000rs is it a good deal?
  38. That's a good card. I almost bought one myself not long ago.
    I'm glad you're not going to trust the CM PSU. Its claimed wattage was certainly high enough, but its quality is not.
