Hi,

I'm currently looking at purchasing another computer, and was wondering how much importance there is in power supply for a case. Here are the current hardware items that will go into the case:

CPU: AMD Athlon 64 3800 Dual Core
Motherboard: Asus A8N SLI Deluxe AMD64 MB
RAM: 2048Mb DDR2 533
HDD: 300Gb Seagate 7200RPM SATA
GPU: Leadtek Geforce 6800GS 256Mb
Sound: Creative SB Live!
Pioneer DVR A10 XL DVD Writer & 3.5" Flopppy Drive

I don't know if this is also worth mentioning, but this computer will also be running new, graphic-intensive games, as well as 2D and 3D graphics software.

Would 360W be enough to power all of this, or should I source a case with more? This is one I'm currently looking at:

TA-250

Thanks for your help!

Seems like you might need more. But keep in mind that many times a brand name, high quality PS will out perform a no-name generic with a higher watt rating.

As a side note, forget the Creative SBLive, it's junk and not up to today's games.

Frankly, for that system and what you want to do with it, I would consider a 450w to 500w just to be on the safe side...350w may be middle ground or on the weak side and could give you headaches. Get quality; the best you can afford....Antec, Enermax or a Thermaltake.
Good rule of thumb: Go for at least 100w to 150w more power than you anticipate to "future-proof" the system.

Ditto MysticEyes on that sound card. Consider a SoundBlaster Audigy ZS. I would just get the card, not the "gamer" version...same card, but just with a game bundle. Save the bucks. You might want to consider getting the Platinum version though with the front panel interface (or external interface).

thats a lot of stuff, the Asus site stinks, cant see how many fans, what size, etc. case looks too small, power supply too small probably not the right type either you need 450 to 500watt 24pin dual rail, SLI ready just in case, Look at Antec, Thermaltake to name a few

Enermax are very good power supplies, try to find a good case without psu and get an Enermax power supply would also work.
