I'd like to upgrade RAM in my old desktop PC (running Windows XP Professional SP3) from 1GB to 4GB. Both are DDR2 and clocked at 667Mhz. My question is: will I need upgrade of power supply? I've got stock 230W power supply now. (other components --> CPU: AMD Athlon 64 X2 4000+ which is Dual-Core clocked at 2.11Ghz, 160GB HDD, MB: GAM61SME-S2, GPU: nVidia GeForce 6100 nForce 405). I'd like to upgrade this PC to Win7 or Win8.1 x64. I won't play any games, just use it for work (Word, Excel, PowerPoint, Photoshop, browsing the web via Chrome and videocalling via Skype). Thanks in advance.

If your wanting 4GB, yes you will need an upgrade of power supply, because the current power supply you have right now may not support a new number of GB, and for your sake I would not risk your upgrade process failing due to too low power supply. 

Hope this helps!!

Depends, but likely you can add the memory without any worries.  DDR2 memory stick only uses about 2 watts.   Your CPU, video card and hard drive are the power hungry monsters under the hood.   I have added more memory to every computer I have ever had without a power issue.

So will I need new power supply or not? I'm frustrated. blush
