4850 question

[nonewsgoodnews]

I've been waiting to get a graphics card until a good deal came up. I've bought several for others' computers just not my own. Today might be the day.

Newegg is running a 4850 for 100 free shipping:

Is this card a good fit for my pc though? My main concern is the power supply and whether its good enough or not.

Phenom II x3
4gig ram
500gb caviar black
Corsair 400 watt
Samsung dvd burner

My question is this, can my pc sufficiently power this card or should I instead get this:

Which I figure would be cheaper than getting a new psu but from what I understand would give the same performance?

The graphics card guide seems to say the 4850 at $100 is a great value and if I can save 30 I would like too however I don't want to blow up my pc either... My monitor is only 1366x768 so I figure the 4850 should play everything on high or medium settings?

Your PSU is one of the best brands around so I would think it can handle the HD4850 just fine. It's a good deal and should be great for that resolution. There's probably only a few games where you wont be able to max out the settings

I am pretty sure that the Corsair 400 can handle it! It is better than many 450watt generic PSU's

Your PSU have a 6pin power connector for PCI-E card, right?

The card comes with an adapter even if it doesn't have a connector.

It is my understanding that you will need 26A on your 12v rail. I don't think your PSU can handel. Please check. Yes, Corsair is a great brand (I have one), but I think you'll need a bit more power for the 4850. You do stand a much better chance with the 5750. I think even the 5770 draws less power then the 4850. Both are MORE than fine for your resolution.


ATI Radeon™ HD 4850 System Requirements:
450 Watt or greater power supply with 75 Watt 6-pin PCI Express® power connector recommended (550 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)

It's gonna be close.

I'd go for the 5750. You'll pay a premium. But it's a better card... an improvement in technology if you will

400w Corsairs tend to have 30 amps on the +12v rail. It should be fine. The HD5750 is worth considering as it's slightly more powerful, DX11 and much lower power but with such a good deal on the HD4850 I'm not sure if it's worth extra money.

tough choice since the 4850 is such a good deal. the corsair 400w psu will run either fine. my room mate has a corsair 400w and a 4870 and its been going strong for a year now.

Your PSU will be fine. Don't worry about it.
