Don't even point that PSU in the direction of that card.
I take it you have a Core 2 Duo or Quad to go with it. Even though your system will probably use under 350W (if you measured it from the wall it would probably be like 310W), I wouldn't really trust that PSU to handle even 80% of it's stated output without burning out. There is a reason that at least a 550W unit is recommended for a single GTX260. Anyway this is a good PSU that should suite your purposes as it's very efficient and won't break the bank
Corsair, PC Power & Cooling, and Seasonic all have a reputation for high quality power supplies that are very stable and reliable. They consistently earn high marks in technical reviews and comparisons. Those three psu brands are the ones most often recommended by veteran posters at this forum.
Please list the rest of your pc components
Are you a hardcore gamer?
Are you into overclocking?
Are you planning on using multiple video cards in SLI or Crossfire mode?
It's difficult to make a specific recommendation without the additional information.
The Corsair VX550 that megamannx00 mentioned would be a good choice for you. It has a single large +12 volt rail rated at 41 amps. It can definitely handle your system if you are not going to overclock or not going to use multiple video cards.
The Antec Earthwatts 500 is another good choice. It too has earned favorable reviews. If you decide to get this one make sure it is the new version. Check the specifications before buying. The old version had mutiple +12 volt rails rated at 17.5 amps each. The new version has mutiple +12 volt rails rated at 22 amps each. The new version also has better internal parts.
rofl @megamanx00. The Sparkle would probably live up to its name, however briefly, if connected to that GPU. The Antec Earthwatts 500 would be a great choice.
No need for DDR2-1000. Get this DDR2-800: http://www.newegg.ca/Product/Product.aspx?Item=N82E1682...
mushkin 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - $48 after $10 MIR. It isn't the cheapest, but it is very good RAM.
If you are not going to overclock, you won't like the E5200. It is a mutt at stock. You won't need an aftermarket cooler if you don't overclock. Take the money from that CPU plus the cooler, add the change out of your couch, and get an e7400 instead: http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...
The newer Seagate drives have spawned a lot of horror stories. I wouldn't buy one. Get this 750GB WD instead: http://www.newegg.ca/Product/Product.aspx?Item=N82E1682...
You might consider an ATI HD4870. Same tier on Cleeve's performance chart, but ~$30 cheaper.
About other parts than the PSU , it's too late, already got them (still waiting for the shipping of the RAM... it's on its way). I already received the 1TB harddrive and i learned after buying it that it had bad reviews , so i'll deal with it and hope it will last.
I might consider overclocking it in a far future lol since you say it's kinda bad as it it right now. Still got to learn a lot about overclocking before i test it out though. I'm gonna go with one of the 3 products you guys mention ealier , the 2 antec models or the Corsair one.
Hi, you definatley need a better PSU. Dont get a non brand one like a Sparkle.
You could certainly do a lot worse than Sparkle, which is a division of FSP who at one time were one of the top PSU makers. They used to be the OEM for the PC P&C Silencer. I would not be surprised if the PSU could run this system, but a new PSU is definitely a good idea.
