Best video card for gaming?

300 watt power supply dont wanna change power supply pci x16 i only use nvidia|||Here's where to start:

Enter in all of your PC components and choose various Nvidia cards, click "Calculate" and it will tell you the recommended power supply.



Obviously you do not want to exceed 300w.



You can never go wrong with the Nvidia 8800 GT.

Work out your system on the Thermaltake website and see if your PC can get away with just 300w.|||hi there

its nice to see someone taking notice of their power supply as this is were alot of end-users make mistakes when they buy a luvvy-duvvy gtx285 only to watch it burst into flames as their 300w psu goes into meltdown

however by informing us on your current psu wattage at least we can recommend a graphics card that will run ok and more importantly safely in your pc

theres a few card that fit well into what you have described and the first is the "Sapphire HD 4730 512MB "( http://www.ebuyer.com/product/169173)

this has a 128bit memory interface and some awesome power made up with a 750mhz core clock and 512mb of gddr5 memory running at 900mhz(3600mhz ddr effective)

in terms of power this has bags of it,however due to its mega efficent gddr5 memory this equates to a card that requires significantly less power than older radeon cards and will happily run with a decent 300watt psu,however check your +12v rail(s) just to be sure

another card worth considering is the "Inno3D 9500GT 512MB DDR2"( http://www.ebuyer.com/product/159575)

this has the required 128bit memory interface and some acceptable core and memory clock speeds( 550mhz core/800mhz memory) and with 512mb of ddr2 memory this should run fine with a decent 300watt psu

however new power supplys dont have to break the bank and you can get some decent power supplys for around £30,and one of these which i put in alot of my system builds is the "CIT 600W Dual 12V Rail 12cm PSU "( http://www.ebuyer.com/product/159707)

this has 600watt of rated power and dual +12v rails each delivering 18A on each rail(32A total),and with decent 3.3v and 5v rails this is probally the best budget psu you will ever find

infact i have spoken with a rep from the graphic card manufactuer "XFX" who told me they use these power supplys on their test bays and as you can imagine they go through some tough testing everyday

theres a 550watt model with 16A on each rail and this would run a card such as the nvidia gts250 or the radeon HD4870 without any problems

however when you see a card you like and need to check if it will run in your pc with your current psu then go to http://extreme.outervision.com/psucalcul… and use the "eXtreme Power Supply Calculator Lite "...by entering your system specs you will find out how much your system uses (in watts) and you will be suprised how little power most pc,s need !

i hope this helps,however any problems let me know

good luck mate !|||With only a 300watt power supply your options are very limited. I would recommend upgrading the Power Supply to a 550-600watt with a pci-e connector.



Here is one i found it is not that great but best one i found for 300watt

128bit starts at 350+ watt power supply
