How would you find the volts/amps/whatever of your Power Supply (it's called that...right?)
I want to know if it can support this card: Newegg.com - SAPPHIRE 100176L Radeon X1950PRO 256MB 256-bit GDDR3 PCI Express x16 HDCP Video Card - Retail
Also, when you get more RAM do you need more power?
the easiest option is to open up your case and look on the PSU itself, there will usually be a sticker on it showing the voltages it offers.
What PSU have you got? @ Card Supporting
RAM doesnt take up too much power so unless your PSU is really strained that you need to resort to buying a new PSU for more RAM then it must be weak.
Send us your specs and we can help you out.
Actually, what you want to know is the wattage, not the voltage.
Ya i have a 500W but i am scared i might need more if/when i buy an 8800. But i am running a 7800 now so i dont know if it will take a lot more or not.
Open up your case and look at it, somewhere on the sticker it should say something like maximum output of something similar.
As for the ram, i would say 95% of the time its not going to use enough power to really put a drain on the PSU.
Is your PSU a brand name PSU??

Wattage is only an issue really now in the extreme high-end PC spectrum (QX6800, 2GB RAM, Loads of HDD's, SLI'd 8800 GTX etc. in which an Enermax Galaxy 1kW copes with that job very easily).
You really should be mainly looking for the amount of amperes (Current) delivered on each of the rails. Also, and this is typically the norm now, you should get a PSU with a split 12v-rail design and modular cables. The split 12v-rail design allows the current to be split more efficiently across the PSU and thus more efficient in giving power to the components. The modular cables are useful in the sense mainly that there can be less cabling in your PC (unless you use all the cables) and therefore inprove airflow, resulting in a slightly cooler PC.
You should post your specs so we can see what kind of PC we're looking at in terms of the 'power' (I use that term loosely) range (low, mid, mid-high end, high-end).
