So... i went out and got a 4890 1gb card..... =) which is one of the best purchases i think i've made in a while (OMG so much better than my 8500)

There is just one simple little problem. ^_^ My computer keeps randomly turning off.

So I looked inside and... viola~... 300w power supply.

> > Now I don't really think that's fair to my shiny new graphics card that can actually render shadows without running at 15fps. :lol:

So, psu you guys got in mind that would be preferably less than 80 dollars? xD I kinda ran out of money buying the card.... > > i need the rest for bills.. and... car insurance.... ._.

If you can stretch by $9, get THIS.


Although one of THESE should be able to power the card, although I can't guarantee it.

You only need 500W-600W in reality, unless you are running an ub3r overclocked multi-GPU rig.

Antec is a good brand. This 500 Watter should run everything just fine:

Newegg.com - Antec earthwatts EA500 500W Continuous Power ATX12V v2.0 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC "Compatible with Core i7/Core i5" Power Supply - Power Supplies



Also, PC Power and Cooling makes GREAT PSU's. This one, even though it says 470W, should perform better than the antec PSU aformentioned:

Newegg.com - PC Power and Cooling Silencer 470 ATX 470W ATX12V Ver 2.2 Active PFC Power Supply - Power Supplies



OCZ supposedly makes good PSU's. However, the gamexstream I got was really noisy. I RMA's it, and got another noisy one. If you buy one of these modular PSU's, research to see if the noise is good on that particular model, for OCZ may have cleaned up their act. The benefit is that OCZ's mail in rebate process is easy, albeit slow.

I suggest the 600W over the 500W, if you do choose OCZ:

Newegg.com - OCZ ModXStream Pro OCZ500MXSP 500W ATX12V V2.2 / EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC Power Supply compatible with core i7 - Power Supplies

Newegg.com - OCZ ModXStream Pro OCZ600MXSP 600W ATX12V V2.2 / EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC Power Supply compatible with core i7 - Power Supplies



My personal favourite is the PC Power and Cooling PSU, as it has a single rail and a 5 year warranty. You really can't go wrong with it, and its supposedly silent. I'd definitely recommend it over the modular OCZ PSU's I have shown you, and it likely beats the Antec PSU in power output. The only downfall is bad efficiency, and its lower wattage. However, 470W should be plenty enough for anything you throw at it, even if you throw in another 4890 (though don't quote me on that).

The 5 year warranty alone should be convincing enough to forgo the Mail-In-Rebate required by the other PSU's and just buy the equally priced PC Power and Cooling PSU :) .
