Graphics Card Buying Advice Needed

[abhilashkrishn]

Im planning for Graphics update of my PC. My PC having 300W Powersupply now. I can buy maximum 360W SMPS for this.

Which Graphics card need to select from these?

ATI Radeon HD 5450, HD 5670 and HD 6670

Also please guide me which powersupply can I select for this Graphics Card : 300W or 360W (not more than that as my UPS not support more!)

My system configuration is as list as below:

Intel DG41TY Motherboard
Intel Pentium Dual Core E5200 2.5GHz
2 x 2GB DDR2 RAM PC2 6400 800MHz
Seagate 500GB SATA2 HDD 7200RPM
Seagate 1TB SATA2 HDD 7200RPM
LG DVD+RW
300W SMPS
USB Mouse
PS/2 Keyboard
18.5" Wide DELL LCD Monitor 1366*768 Res
V-Guard SLENDER PLUS 600VA UPS

300w is more than enough for any of those 3 graphics cards
of those, the 5450 is by far the slowest
the 5670 and 6670 are roughly equal

thus, 5450 << 5670 = 6670

assuming your usage is for video gaming and based on your listed computer, i would recommend the cheaper of the 5670 or 6670

Thank you for reply. But the ATI site is showing HD6670 needs 400W powersupply. I have only 300W. Will this make my system burn if I connect HD 6670 into my system?

That 400w is a total system recommendation just because modern components can easily be overclocked and draw much more power. A 6670 in itself isn't power hungry at all.

That means I can go ahead with the plan to buy HD6670?

his system with a 5670 or 6670 would probably hit around 150-160 watts or 13 amps during games. we need to know how many amps are available on the 12v line of his exact model 300 watt psu. many 300 watt psus are only rated for around 15-18 amps even when brand new.

If you plan a new PSU you can get any, the PSU will not draw and use more than it's needed by your components. What's your budget for the PSU+Video card and where are you buying from?

I just got a 7750 and I am using a 300 watt psu. I am really enjoying the 7750 since I upgraded from a 5450.

sorry but that means very little without saying the exact psu model and listing all of your other specs.

Thanks for reply.
My current SMPS is chinese made and I don't know the current rating of 12V. But I will measure it using multimeter.
My budget is $175.

You can get something like this:

Antec NEO ECO 400C 400W (360W on the rail that matters, +12V)

http://www.newegg.com/Product/Product.aspx?Item=N82E16817371029

SAPPHIRE 100328L Radeon HD 6770

http://www.newegg.com/Product/Product.aspx?Item=N82E16814102940

LE With this, the system will consume some 200W in gaming.

Get the 7750. Better than all listed here and it uses 45W under load. Keep your PSU. End of the story.

Agreed. Don't pay more than $130 for it though; there could be some mark-ups on it initially...

Great budget card with no external power connections needed.
