What size PSU should I use?
Last response: in Components
First time posting on this forum but heard how knowledgeable everyone is on here. I am currently building a new pc and feel that my older 500W Ultra will not make the cut. Below is a list of my components that I will be installing. I would like someday to have an SLI config. Any help or suggestions would be appreciated.
Also I have the pc up and running with a ATI Radeon X850XT but will be removing it when the EVGA comes. I currently have Vista Ultimate 32 bit (received free at tech conference) installed but wondering if it is worth going 64 bit. I do alot of FPS gaming.
PC build:
EVGA 512-P3-N879-AR GeForce 9800 GTX+ 512MB 256-bit GDDR3 PCI Express 2.0 x16
CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)
MSI K9N2 SLI Platinum AM2+/AM2 NVIDIA nForce 750a SLI ATX AMD Motherboard
AMD Phenom 9850 BLACK EDITION 2.5GHz 4 x 512KB L2 Cache 2MB L3 Cache Socket AM2+ 125W Quad-Core Processor
ZEROtherm Nirvana NV120 120mm 2-ball UFO Bearing / Transparent CPU Cooler
Vista Ultimate 32 bit
Antec three hundred case (PSU bottom mounted)
Thanks again

try using
http://www.extreme.outervision.com/psucalculatorlite.jsp
to determine what wattage you need (including overclocks),
then find out what minimum amperage you need (GFX card site will usually tell you the gfx card needs, pay attention to the amp needs on the 12v rail(s)). This is a good starting point for amperage calculations.
Then you can make an informed choice on what power (watt and amp) you require.
As sometimes you may only 'need' 500w, but also 'need' 40+ amps (as an example) - and there may not be a PSU available with the amperage required unless it is a 800w or up etc.
Hope this helps
