graphics card my psu can handle

Emachines / Et1331g-03w

Specs: Windows 7
i just bought an emachine: running win7 64-bit and its running like a dream. everything is great except the onboard video. (wow runs all low 20 fps.. as opposed to my old 6800XT running it mid-high 30+ fps).
it has a pci-e slot but the problem is the 250W power supply. most cards list a reqiurement of 300w+.. i know this is a high number so they cant get screwed, so i planned on using a card with a 300W reqiurement anyway.. but then stopped to consider how much wattage the dual core uses, and the extra ide drive i threw in.. and thought of the possibility of exceed 250W.. (the geforce is old enough that i would try it, but it also reqiures 18A at +12V, not a reqiurement all cards possess, and my psu doesn't meet it). i thought about upping the psu.. but im not sure which type will fit in perfectly, and i'd rather just throw a video card in if there's one this system can handle (looking at 9400/9500GT.. 300W/350W req. respectively) heres the one i considered most:

basically; can anyone help me find a psu or video card ill be happy with? very budget. im buying one, not both [unless there's a killer combo deal] for somewhere around the $50 ballpark, unless there's a phenominal exception.

thank you :]

Don't buy 9400/9500gt go for radeon hd 4670 512mb gddr3 and if u gonna buy new psu look for 400w with 12v @ 30A eg.Corsair

Probably should have come here before buying an Emachines computer.

Wow, having to upgrade a brand new machine. OtheHill is right. Can you take it back?

every way i built a computer, i couldnt get 6GB DDR2 ram, AMD Athlon II x2 2.7ghz, DVD-RW, and a 750gb HD for under 400. 400 + 50 dollar upgrade seemed more worth it to me than 540 for the same package. I was weary of emachines 5 years ago but if they're still around they're doing something right. like I said I'm no hardcore gamer anymore, this computer runs sonar 8 (my recording software) very fluid, I just kinda want games not to completely suck, should i feel so inclined to play one :]
I've done some more reasearch on PSUs, I think I am going to buy this 500W diablotek .. any suggestions on where I'm at? [aside from 'diablotek is not a big name, spend more on a rosewill' (which I still might do)]

thanks for your responses

I would go with this. it has a single 12 volt rail and has some room to grow.

Emachines was bought by Acer some time ago. Still use the same crappy hardware. Especially the power supplies. Figure what you are spending for both a graphics card and a new power supply.

Can anyone inform me as to why its BETTER to have a single 12v rail? If so, why do they add a second at all?

The logic behind multiple rails was to feed clean power to each of TWO or THREE graphics cards ( SLI & Crossfire) plus feed the CPU and then have more rails left over to use for drives, etc.

The problem with most multi-rail PSUs is that while there MAY be enough power overall it may not be enough on each individual rail.

For example, a system with a single high performance graphics card may need 25Amps just for the card. The individual rails may not have 25A capacity.

On single large capacity rail doesn't necessitate balancing the loads either.

The reason many PSUs with multi-rails are on sale is because manufacturers are reverting back to single rail configurations.

Going back to the multi-rail setup, one rail is usually dedicated to each graphics card and will have the special PCI E power connectors. One rail will be to feed the CPU directly and will have the special connector for that.

Hope this is clear enough for you.

So, some rails may not have enough power and some too much.
