Hi,
I had posted a question somedays ago about getting a new PSU for 75$ budget and told to get Corsair VX450W.
Now i am ready to order it along with GPU. GPU is fixed, i am getting an XFX 8800GT but still very confused about PSU. (The maximum budget for PSU is still 75$)
CoolerMaster Extreme Power RP600PCAR 600W PSU is also retailing for 70usd. Which one is better? Corsair has maximum 33A on 12V rail but it only has one PCI-Express connector, although i don't have any immediate plan for running SLI setup but i am also not sure if do it in the future. and does this Corsair 450W will be able to handle the upcoming 9800 GX2? Why folks still recommend Corsair 450 for 75$ budget? just because it has japanese capacitors in it?
I know DDRIII is better but can 1GB DDRIII 1333mhz beats 2GB DDRII 800?

Coolermasters generally dont rate well when in the same price range.

I think you are trying to get the best of both worlds (functionality and low cost) but with power supplies that doesnt really happen, in fact with most things that doesnt happen.

If you dont want SLI later get the Corsair450 and be happy with it. If you want something that will last longer and give you SLI or upgrades later get the Corsair520 or 620 or PCP&P 750w model (these are more expensive yes but some of the best out there).

Most people here will tell you that DDR3 makes little to no difference and for the price DDR2 is a steal. More DDR2 will beat out less DDR3 at a faster speed in real world anyday of the week.

Agree with chookman re getting a good PSU. I see PSUs as a long term investment, i.e., use it through several builds so worth putting a bit more money into it. Antec, FSB, and Seasonic also make good PSUs. You can get a good 500w to 550w for around $100 give or take. There are always rebates of some sort. Take some of the money you save getting DDR2 and get a better PSU. With the rest of the savings you could put a down payment on a new car

@chookman
Actually this rule's apply to anything you purchase, the expensive an item is the better it is. But i want to get the best under some price range.

So the corsair 450w is the way to go? also you have any idea that will this PSU be able to handle the upcoming Nvidia 9800GX2?

Not true. It depends on the quality of the manufactured items. I have seen people shell out like $150 for a no-name PSUs which died at the end of the month. If you plan on going with the dual GPU cards, you need ATLEAST 600W. Those cards are pretty power hungry. I would personally recommend a Corsair 450VX for your budget.

$70 after MIR.
But remember you wont be able to get a really power hungry card like the 3870X2 in the future.

Those solid capacitors are a BIG +. Trust me. Esp. in a PSU where it is exposed to high temps, the solid caps fair much better than the normal electrolyte caps and also the capacitor aging is much lower in the solid caps.

Never buy a PSU from newegg, they rip you on good models and almost never ship them for free.

Same 450vx w/google checkout is $50!
