PSU upgrade?

Question

I am planning to upgrade my psu just because im upgrading my video card. So I found this psu:http://www.newegg.com/product/product.as...
Im upgrading my video card to an EVGA7800GS AGP:http://www.newegg.com/product/product.as...
So here are my computer specs after the video card upgrade:
AMD Sempron 3000+ 2.0Ghz
1 gig of ram (2 512mb sticks) PC2700 DDR400
EVGA7800GS AGP
1 VGA cooler in 2 expansion slots
1 92mm case fan
1 80mm cpu fan(heatsink)
1 DVD-R/CD-R(RW)combo
1 80GB 7200rpm hard drive
USB mouse and PS/2 keyboard
1 front bus memory card reader

I am not overclocking anything so will the PSU support my video card and my other hardwares? If not what psu do u suggest from newegg? I am a budget gamer so I want a cheap psu that will support my system. I am currently using a 250W psu with 14amps on +12 rail. Am I overpowering I mean am I paying to much electricity to make my system work? Cause i dont plan to OC. If Im overpowering what psu do u recommend

Answer 1

The 7800GS AGP draws up to about 55 watts. You need 18 amps or more on the +12V rail for cool and stable running.

If you put a 500W power supply, it does not mean your power bill on your PC will also double. Your PC will only consume what it needs and not that entire rating. +12V output is now more important because most of the power is drawn from that voltage rail. And some 500W power supply may only have 300-350W available on the +12V rail.

Here is a cheap but good one. Gives you plenty of room for upgrades:

Answer 2

Put simply, if an 8800 needs minimum 500w psu, 250w WITHOUT over clocking should be just fine. Just remember, computer parts are like cars- the brands DO make a difference. Are you paying too much electricity? No, unless you're playing video games for 12 hours straight and the game is running at 60fps with the max settings your computer can achieve without bogging down the game. Can't specify EXACTLY what PSU you need, but a few good brands are Thermaltake, Corsair, and Antec. Make sure you do your research and trust others opinions. If your not sure about something and their using a certain product, their opinions should have a little credibility in deciding over a bias thought you may have. Good luck!

Answer 3

Links don't work. but you probably do fine with a 400-500 watts power supply. Make sure you get a good brand name. It makes a world of differences. Go for antec. One of the top brand for power supply. Don't go cheap on power supply. i had 2 or 3 cheap name brand that failed on me. It will drive you crazy once the power supply start to fail becuase it will seems like its the cpu and motherboard that is failing, so dont go cheap.


hope that helps
