Reccomendation on how big of a power supply ill need?

by corezapr / July 16, 2006 11:50 AM PDT

I'm building a new computer and was wondering how big of a power supply I'd need. Below are some of the components

AMD X2 4400
ATI X1900XT PCI Express 512mb
Hauppauge 500 Dual TV tuner
Creative Soundblaster X-Fi XtremeMusic
2 400 gb sata harddrives
2 DVD Drives (1 DVD Burner, 1 DVDROM)

Any reccomendation? Would 500Watts be ok? Or should I go a bit higher? I don't want to cause problems, but also don't want to have a really noisy machine.

Thanks, I appreciate all that have helped with my questions on this forum for building my new comp.

Good afternoon,

I have an AMD Athlon 3500+ with 2 GB of ram (4 3200 crucial DDR pieces, not super fast RAM), 4 hard drives adding up to 1.3 TB an ATI All IN Wonder AIW x300 video card, built in audio, I forget the motherboard, a crummy ECS something or other. Got the cpu and MB deal at Fry's electronics a while back. 1 dvdrw drive - NEC. I run a 550 watt power supply unit with dual fans, i think it is the Antec TruePower 2.0 550W. I have had it running almost 24-7 for about 10 months. Works well. I would play it safe if you are going to increase the number of hard drives later. I increased mine and probably will again. Plus, you have a power sucker video card with a tv tuner card and the audio card. Get the Enermax 660 watt model EPS12V 660W. A bit pricy but with the machine you have, it's worth it. I have that one on my other machine, it's awesome. Super cool, air never flows warm out of that thing, even when I used to live in Riverside, CA (pretty warm/hot place). Best of luck. Let us know how it goes.

Having a high wattage unit installed won't hurt your system. The system will take what it needs on demand. The bigger the wattage the better the wattage cushion as system needs grow. Yeah, it's big enough BUT it must be a namebrand psu. That way, you'll get the true stable output any system will need. Heck, they're 600W+ psu out there now. Consider, whatever the final calculations are for your needs then add 25% to it for a good indication of a good fit.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
