I currently have a I have a Gateway DX4300-22, and want to get a new power supply.
I want to purchase http://www.newegg.com/Product/Product.aspx?Item=N82E168..., and am wondering if it will work for my computer. Right now I have a 300w power supply, and that is all the info I have on my current Power Supply.
Main Connector 20+4Pin
+12V Rails Single
PCI-Express Connector 3 x 6-Pin, 3 x 6+2-Pin
SATA Power Connector 12


How can I know if that powersupply will work for my computer?
If it helps, I think that my motherboard is JetWay JNC81-LF AM2+/AM2 AMD 780G HDMI Mini ITX AMD Motherboard
(http://www.newegg.com/Product/Product.aspx?Item=N82E168...)

Please help me!!!

If you don't know if this power supply will work with my computer, please tell me how I can tell so I can look it up myself.

Being a mini tower it should fit a normal size PSU But the PSU selected is total overkill for your setup since you can hardly cram in enough hardware to utilize half its output power. Here is a quality 520 watt unit http://www.newegg.com/Product/Product.aspx?Item=N82E168... that would run your computer with all but the most powerful GPU's on the market which would be bottlenecked by the rest of your setup.

well you see I want to get a GTX580 Graphics card, and new RAM too. I just want to make sure that the powersupply will support my graphics card.
I can get that power supply for 100.00 new, it is usually 250.00.


I figure that 100 isnt bad considering that I would not have to worry about my power supply again for a long time.

I could also go for this one I guess...
http://www.newegg.com/product/product.aspx?nm_mc=AFC-Te...,
but that is only 600W

Will the original overkill powersupply still fit into my computer if I did get it hypothetically though?
Do you think that 600w is good enough for a high quality graphics card and upgraded RAM (I want to upgrade my ram to the highest that my computer can handle)

Thanks for your reply btw.

a gtx580 wouldnt even physically fit in your case and your CPU will bottleneck a gtx580. you would see no difference between a gtx470 and gtx580 with that CPU as it will not be able to feed the gfx card the information fast enough.

The max GPU I would put in your setup would be GTX560 Ti!
