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!)

Enjoy, but all power supplies are not the same, what, brand power supplies, are we talking about here.

I can say that it is not branded, it is Chinese. Will it burn my PC if I connect HD 5670/6670 into it?

I would have to know the 12volt rail amps to say anything, it is on the label

The power supply will put out what ever you connect it to, if you have too much for it to handle, it gets hot, and eventually thing can begin to fail, and voltages will drop.

When cheap power supplies, fail they can take out the whole motherboard,

Amps on the 12volt, how many 12volt rails?

[stroyal]

Actually that list is a little high, now that I look at it.

[stroyal]

All 400watt, or at least a good 350watt.

ATI Radeon™ HD 5670 Graphics

ATI Radeon™ HD 5450 Graphics

I have to check that using multimeter. I will buy one from friend.

Are you saying that I have to buy 360W SMPS for HD5450? Or will it serve for HD6670 also?

[stroyal]

No I 'm saying a quality 350watt would run any of the 3.
A non brand name like you seem to have would have to be a 400watt, and some are so poor they have to be a 450watt.

You can't check amps with a multi-meter, only volts and ohma.

You would need an amp meeter, and that would not tell you what the power supply is rated for, only what it is drawing at the moment.

Is there a Sticker or Label on the PSU in the case with info on it?

[e.a.x]

I do not believe it will "burn" your PC if you plug it in. But I wouldn't trust a PSU as you have with some new hardware. I didn't know much about PSU's when I was in the market, I was told to get a Corsair and never had any problems for a 2 + years.
