I recently acquired an HP computer with an Intel core i-5 3330,6GB of RAM. The only downside is that the power supply is only capable of 100 Watts max. My old video card an Asus HD 6450 Silent would not work when i plugged it in and wouldn't let the computer boot up and would just beep. So if you can help me find a new card that would be great.

I think you would do better to get a new power supply instead, something about 500w but not too cheep.

its a brand new machine and I do not want to modify it yet

Well, I don't think you really have an option. If it's a normal size Micro ATX case (not slim tower), you will easily be able to replace it. Cooler Master has a pretty good power supply that has 500 watts which would be perfect for your needs:

Your story doesn't seem to make a lot of sense. You just said that you don't want to modify it, but yet you want to use a powerful graphics card. It's all modification to me.

well i dont want to do major upgrades like the power supply and stuff. I consider minor things like RAM, Graphics, HDD

Make sure the videocard still works and double check the power supply. 100 watts seems too low for a system using a desktop CPU as the CPU can pull 77 watts, and you simply cannot have all of your power on the 12V rail. A motherboard can easily pull 20-30 watts, and then you are left with hard drives which can pull 8-10 watts of power. (then what happens if you have a DVD drive)

I don't think that is a 100 watt power supply as if it is, it would be unsafe to even use as they would have to overload it to run that system without the extra videocard.

100W seems far too low, i don't not believe you, don't get me wrong, I just can't beleieve HP would be so stupid to put something so low in a modern desktop, considering the i5 itself uses 77w. 100w will barely power the system as it is, if that's all you have there is next to nothing you can do. Sorry

First off if you are only having a spare 100W look into a new PSU which at times gives a performance increase itself. I am using a Seasonic 620W to power everything and it is very efficient and powerful.


Secondly assuming you get a a better PSU I assume you want a cost effective card that can handle enough thrown at it.

nVidia card, 650 ti - http://www.newegg.com/Product/Product.aspx?Item=N82E16814130838

AMD Radeon HD 7750 - http://www.newegg.com/Product/Product.aspx?Item=N82E16814202011

Both of those cards Are identical in performance ( the 650 is slightly faster ) but the 7770 is cheaper and should be enough if you are not a lot of graphically intense gaming. So remember, PSU first then get a Video Card

Please read and answer the question. Just naming a brand really does not help because they could buy one that is not compatible with their system.
