Thanks for your help in advance! I posted a few days ago but now I have a better idea of what I'm doing.
I am upgrading with a mobo and processor that were given to me. I want to do this cheaply but still have it be worth the money.
To put things into perspective I am running an old Athlon XP 2500+, 1GB ddr 3200, ATI9600 128MB, and Asus A7V880 mobo. I'm not looking for this build to be a modern day hot-rod, just a great improvement.
I used 3 psu calculators and found the highest watt calculation for this setup was newegg's at 373 watts.
I have an Antec true430 and I am wondering if it will work, it has always run very well. The video card I selected does not use a power connector.
Will this PSU work? It has a 20-pin and a 4-pin and SATA power. http://www.antec.com/specs/true430_spe.html
I have a case, dvd and cd optical drives. I may use my basic sound card if the onboard has driver issues. No other cards or hardware.
Yes, a 430W psu that delivers its rated power cleanly (IOW, a psu in good working order) wil power the system. And yes the 20pin power connector will fit on one side of the 24 pin slot - the 4pin will fit in the 4pin.
Power requirement for your vid card can be found here:
If you see a typical efficiency curve you will notice that efficiency varies according to the power being delivered and usually the power supply achieves its highest efficiency when delivering between 40% and 60% of its maximum capacity. Efficiency is also higher when the power supply is operating at 220 V.
Because of this effect it is recommended that you buy a power supply with double the power you are actually going to pull.
Finally there is capacitor aging. The longer you have used your PSU and the warmer it has been during that time, the less able it is to provide the rated amperage. A 430W PSU that is two years old may only be able to provide 350W at 30C.
So can you use your PSU? Maybe for a bit, but it needs replacing. You can bet you'll be losing money on the electricity bill.
A $50, 600W psu is exactly that. Please stick with Antec (Earthwatts, Truepower), Corsair, PCP&Cooling, or Seasonic. The known quality of those brands/lines allows recommendations. For any other psu, google "PSU_Name_Model rveiew" and find someone who has actually evaluated the guts and measured performance. if you can't find a review, its an unknown commodity.
I just placed my order and went with the CORSAIR CMPSU-450VX. Totaled $200 with shipping and rebates.
Now I just hope the rebates go smoothly.
Thanks for all the good work you guys are doing for people.
