I wanted to upgrade to a 4850 1GB but I need a new PSU as it is only 300W. Since A PSU is going to cost me atleast $100 I am now going with a 3870 for only $150 compared to $300 for the 4850 (I am in Australia).

The PSU I have is a:
Model: Bestec ATX-300-12Z Rev:EHR
Input: 100-127V-7A 200-240V 4A

I have a:
MSI - MS-7525
Dual Core @2.4GHz e2220
3 GB PC2-6400
9300 GE 128mb Graphics (Upgrading to a 3870)
360GB HDD
DVD Burner

This is the PSU I was looking at http://www.techbuy.com.au/product.asp?at=51&prodid=6479... for Corsair 650W I can get one for $148, Thermaltake $128.
I was also wondering if this would run a 4870X2.

So will this PSU go straight in? I do not know anything about PSU's and Google wasn't being my firend, I could not find detailed information on PSU's if you know a site that has please direct me =]. If you need more information please say so.

Thanks =].

The corsair should work with 2 4870's provided you're not overclocking. I recommend against 2 video cards unless you have excellent case airflow and don't mind the extra noise.

The Corsair power supply is an excellent choice. Corsair consistently earns high marks in technical reviews and comparisons. I build pc's for friends, neighbors, and girlfriends. I use Corsair exclusively. They are very stable and reliable. You should not have any problems. It should be a simple exchange - out with the old, in with the new.

Oh ok so you think I should pay the extra and get the Corsair then? I do have a $300 budget and that will still fit =].
Well I guess I will get the Corsair if there really that much better. If it dosen't fit what am I supposed to do then sell it or mod the case if it nearly fits?

**EDIT**
The card I was going to get was here http://www.xpmicro.com.au/cgi-bin/xpmicro/VCSPHD3870-DD... but I just realized that is a HD 3870X2 WTF? How are they allowed to do this? That means the real 3870 probably dosen't even have an exhaust...

I would go with the Powercolor 4850 for $249 & Seasonic S12II 430W for $89. Slightly over budget.

You could also get an HD4670 for $145 which would not require a new PSU.

Yes I guess I could although ATI recomends 450W or higher I think, well mabye I could go for the Cooler Master 650W since it is not much more and the 4850, as that is only $50 more then I was going to get the 3870 and the corsair 650W. Yes I thought of the HD4670 although I don't think they are fast enough =]. Thank you that pointing out that that 3870's are a bit of a waste of money. I can get a Palit HD 4850 for $220 but I wanted an exhaust so I was thinking of the GainWard HD4850 512mb http://www.bttech.com.au/gainward-pcie-ati-hd4850-p-206... for $250 My only consern is that some people say they regret not getting 1GB although me having a 9300GE 128mb I guess I'm not going to miss it =]. Ok so the GainWard & the Cooler Master 650W comes to $346 so not all that much more if there are no objection I think I will be going with that.
Thanks

For a 4850, I don't think 1GB versus 512MB matters. I would take the Seasonic over the Cooler Master any day. 430W is plenty for a quad and 4850, so your rig will easily run with that. If you want a little extra room to grow, get an Antec Earthwatts 500 or Corsair VX550 or Seasonic 500W.

Ok well the Antec Earthwatts 500W is $105 since you seem to recommend that I will go for it then. The others are more around the 140 mark and I don't have the money to spend, Is that all then? I will be buying it soon today or tomorrow so if you need to tell me something please do it soon =] thanks

The Corsair 750 is on sale for $119.99 and after mail in rebate it is $99.99:

Considering the price it is a better deal than the Antec and you will be prepared for future upgrades.


He's in Australia and the price there is a tad higher! ;)

Yes theAnimal is right I am in Australia and to get that from NewEgg it would be $160 + postage the caorsair 750W here is $200 =[. I wish I upgraded before the AUS DOllar went to 60c =[ but oh well. Anyway I would still like to know if the Antec Earthwatts 500W for $105 is going to be better then the PowerCooler 650W for $110.

AW NUTS! I'm missing stuff left and right tonight! Must be from all the Super Bowl excitement.

punkinator - The Antec is perfectly acceptable and preferred over the CoolerMaster.

I think it's time for me to shut down for the night!

The Earthwatts is better quality than the CoolerMaster.
