300w Powersupply good enough for my system?

[Achilles97]

I am building this:

nForce2 mobo
AM XP 2100+ TBred B
512 megs DDR 2700
10 gig HD
32X CDRom
Floppy
Zip drive
onBoard sound
Radeon 9500 Pro
External modem

I plan on slightly overclocking this system (maybe up to a 333 FSB)

Do you think a 300w Powersupply would be good enough for my system, it doesn't have many extras. I don't plan on using the firewire, LAN, etc...

This is the case/PSU I was looking at:

What do you think?

Thanks!

Easily - I doubt that system draws more than 150 watts, even when running at your peak. One of the greater myths of the PC world is that you need a large PS to drive high end componenets (barring, of course, odd nvidia products that suck 70+ watts).

I HIGHLY reccomend a seasonic 300 watt power supply (about 45 bucks at newegg) - for a good site on selecting ps's, try:

Total wattage means squat. Can the powersupply provide the proper amount of current on the 3.3 and 5-volt lines that modern processors need is the question. Most name brand supplies do. Most no-name or cheaper ones do not. You need to know the specs of what's in there.

I have found power supplies to be finicky. My NForce2 with Athlon XP 1600 would not power up at all with my Antec 300W PS, but works fine with my 420W Turbolink. The 300W Antec would also not power up my Biostar board either but worked fine with an Abit KG7. Then I have a 320W TTGI PS powering a ECS KS75A board, Athlon XP 1700, 3 HD's, 2 CD-Drives, and every PCI slot full without a hitch.


I would buy a 420W PS minimum if you are buying new. I just bought a 420W Gold colored Silent (supposedly) TTGI PS from Directron for about $61 bucks shipped to replace this noisy 420W Turbolink. If you are looking for a new PS, TTGI seems to be pretty high quality.

That's way too cheap for a good quality case/psu combo. As has been said, 300w is enough, provided it's a quality unit. Be prepared to spend at least twice as much.
