That puts me at $652. I plan on reusing my old case that I got back around 2004.

Besides wondering if there are any glaring issues with the selections I made above, I am curious if I can reuse my old PSU. It is from 2005 and has been used in 2 builds so far.

It is an:
OCZ PowerStream OCZ520ADJ 520 Watts ATX

If it is unwise to continue using it, would either of these be a good choice?
OCZ ModXStream Pro 600W Modular High Performance Power Supply ($63 + $6 S/H)

OCZ Fatal1ty 550W Modular Gaming Power Supply ($75 + $6 S/H)

Even though one is 600W and the other is 55W, they seem to put out the same Amps over the same rails. Strange.

I will also need a new DVD burner as my current optical drives are both PATA, and the new mobo does not support that. I will just pick up an $18 one in one of my orders.

Thanks in advance for the assistance.

Editted: Use the template as I should have before, changed the CPU and RAM as per suggested.

Good choices, however that ram will do nothing for you stick to 1600 instead of 2133 ram. For $20 more you can get the unlocked 2500K instead which would be wise.

Unless you overclocking which requires a K series processor you might as well get an H67 motherboard. Just a thought.

 

[bruceoite]

Ahhhh... I missed the difference between the 2500 and the 2500K. Thanks for pointing that out.

It looks like these might work for memory, which frees up funds to get the K series processor.

I am still curious about the PSU however. Do Power supplies generally have an average life expectancy? I need to know if I need to buy a new one or not.

 

[bruceoite]

Any help on the Power Supply?

 

[spentshells]

Time for a new power supply get the 600watt model it was a better buy.

 

[bruceoite]

Thanks spentshells. I also editted my initial pos tot make it easier to read.

One last question. With the RAM, will the low voltage help or hurt?

 

[spentshells]

Nothing to worry about actually. In most cases though the faster(better) stuff will take lower voltages.
