I have a 512mb memory in my current computer (AMD Sempron 3000+) and want to add another 512mb memory stick into it.

Here are my ram specs:

[ DIMM2: Nanya NT512D64S8HC0G-5T ]

Memory Module Properties:
Module Name Nanya NT512D64S8HC0G-5T
Serial Number None
Manufacture Date Week 43 / 2004
Module Size 512 MB (2 rows, 4 banks)
Module Type Unbuffered
Memory Type DDR SDRAM
Memory Speed PC3200 (200 MHz)
Module Width 64 bit
Module Voltage SSTL 2.5
Error Detection Method None
Refresh Rate Reduced (7.8 us), Self-Refresh


I looked on newegg.com and found one by Rosewill

Rosewill 512MB 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) System Memory - Retail

Would this work with my current specs?

Also, i am purchasing a new video card for this current system and have a 300watt power supply, the video card needs 300watt power supply to run, will adding more ram take more out of the supply which will cause malfunctions to my machine?

Thanks.

That should work ok, the only problem you may come across is if the two brands are not compatable, this will just be a trial and error thing. It is usually recommended to buy the same brand and model of ram. Although in saying this I have mixed ram in the past with no problem at all.
As for you PSU, you may be running on the edge with a 300W, I suggest you try it out and if you do start to have issues you can start by removing the ram you bought to eliminate conflicks ( this is if you install ram and vid card at the same time ) if you still have trouble it could very well be that your PSU can not cope.
500W or above sems to be a good starting point these days as it will let you allow for future upgrades and it is important to buy a good brand name as the generic ones don't seem to be able to supply the wattage they state. so if your 300w PSU is a generic brand there is a good chance you may be only putting out say 250w or sometimes less

What are good brand PSU's? I know thermaltake are pretty good.

Installing a PSU would it require me disconnecting EVERY thing off my mobo, optical, etc. and replugging it into the new PSU?

One more question,

Is every PSU the same? Or do i need to look at mine and get a compatible one?

enermax and antec are also good PSU's, Im an Antec fan myself.
Unfortunatly, Yes you will have to disconect everything that runs off your power supply and reconect it to your new PSU. It sounds harder than it is as you can not connect something to a wrong plug.
your power supply should just be a standard size and will be mounted with usually 4 screws. One thing to look at when buying is fans and fan size, 2 fans are good and a t least one 120mm fan is also great for cooling.
any doubts just post your questions

I've found one:

http://www.newegg.com/Product/Produc...82E16817182008

Rosewill RV450 ATX 450W Power Supply 100-120 vrms or 200-240 vrms switch-selectable CSA, CB, TUV, FCC, UL

Will that work with my current PSU?


Just to let you know i have an eMachines W3050

The roswill is classified as low end PSU so if it was my choice for a cheaper PSU have a look at these

I would personally go for the thermaltake before the aspire but if it was for my computer I would be going with an Antec but I am not sure what sort of money you want to spend.

The only thing i am not sure of is if the e-machines use a custom power plug or not as I am in Australia and have not seen them around here, your local computer store should know the answer to that
