GTX 660Ti with 460W, Can I?

Hi,
I currently have this PSU installed in my system Cooler Master eXtreme Power Plus 460W .

Now I'm planning to upgrade to an eVGA GTX 660Ti, I want to know that is my current PSU be able to handle it or not?

My usage is just to watch movies, and play BF3 (straight 6+ hours :D ), My other specs are:
1080p Display
Core i3 2100
RAM DDR3 4GB x2
1TB 5400RPM HDD
250GB 7200RPM HDD
So keeping that in mind kindly suggest me should I go for the upgrade or first I have to change my PSU?


I've this PSU in mind if I have to go for a PSU upgrade first.
Cooler Master GX-450W

  1. It can handle it. It needs a minimum 400, but your current PSU only has a 70% efficiency which I wouldnt recommend to play on. The GX 450 would actually be better as its a 80+ bronze. What is your budget for a new PSU ?

    I have the budget to buy GX450, but I just wanted to make sure that this PSU upgrade is necessary or not. If you are recommending another PSU then my budget is around 50-60$.
  3. if its a recent purchase return the gpu and go for a 500 or 600 watt .. the 450 watt will run but if you plan on adding other parts or overclocking any part of your system then you will run into issues .. your better off having at least a 500 or 650 watt .. power supply considering most power supplies are not actually a full rated wattage your more then likely looking at a 420 watt or 400 watt in all actuality because the other wattage is allocated for stuff like dvd/rw drives and or hard drives and stuff like that .. add a bunch of fans or other things and you will find that its rather under powered .
  4. you will get graphical errors and system stability issues .. freezing blue screens and things of that nature.
  5. no, you do not need to upgrade your PSU
  6. So now we have different opinions on this... BTW eVGA website says min. PSU recommended is 450W, the issue is whether 12v, 18A is sufficient or I have to upgrade to 12v, 35A PSU (like the one I mentioned in 1st post.)

    From experience I've had times where my system would take 7-10 mins to just boot into windows, and when it did. The mouse would move at an inch every 5-10 seconds. After research I found out that even the graphics card I had need a minimum off 300, and I had a 350w, it still needed more power. Nothing bad would happen to your system other then it going slow like mine did, or some graphical issues due to the card not receiving the necessary power. A lot of people would recommed to have a certified 80+ psu that delievers sufficient power all the time. A budged of 50-60 on a good PSU would be tough. Your best bet is to look at some on the upcoming black friday deals. As for actually running it on the PSU you have now is pretty close. As the minimum requirement nvidia has posted is 450w. I'll show you some good 500w PSU's for about 60-80 bucks. A 500w in your case would be fine.
  8. Please, do not get any CM PSU's.

    that power supply is not of 460w its really a 430 psu and it cant deliver that much power that is given in the lable :)

    a cx 500w psu seems more better choice its less in price then gx 450w psu and will power your card very well with no issues it has 38A in 12v rail which is good enough and its a good quality and well branded psu:)
