Would a 300W PSU...

[Optimus Prime]

Be able to run these components?

MSI K7N2 Delta-L Motherboard
AMD Athlon XP2500 Barton CPU
ATi Radeon 9600 AGP GPU
120GB Maxtor 7200RPM 8MB Cache HD
2 Generic 92mm Fans
512 MB DDR 333 RAM
Generic FD
LG CD-RW
Sony DVD Player

The 300W PSU came with my case and I'm wondering if I had to buy another PSU, I'm not really bothered about buying a 420W Enermax or such, but I don't want to waste my money on another PSU when the one I have would work.

Thanks in advance.

Well, currently I have a 250W pushing an Asus A7N8X-DX, Barton 2500+, 512 Kingston HyperX PC2700, three 40GB HDs of various mfcg, an LG burner, a LiteOn CD-ROM, a Radeon 9500 Pro (takes an extra bit of power via floppy connector that the 9600 doesn't), 4 80mm case fans, the 80mm CPU fan, the Radeon's fan, and it's own fan.

Not so much as a hiccup since I put it in (and it was in a computer at work for two years before this).

I'd say use your 300W and if things don't seem stable, then upgrade.

That's great stuff mate, thanks a lot Whir.

it depends on the output of the power supply more than the watts. as whir says , the 250 watt is werking fine in that system . just lookk on the side of it and see what the 12v rail says . if it is atleast 16a then you should be ok . amd systems pull hard on a power supply . hook it up and let it run for a while . after you have run it , playing a game for a while is a good test , touch the side of the power supply . if it is HOT to the touch you might want to think about getting a better supply . if it is hot then it is working to hard .

Good point, Omar.

And just to spin your head even more, my 12v rail only runs 12a.

man your lucky it runs ... the cpu uses like 7.5a alone ...

but i would rather be lucky than good anyday .

Wait, isn't that backwards?

i found this in one of the post and found it very useful.

power supply calculator

hope this helps

Those PSU calculators are not very good in my opinion. They just tell you the WATTS.

It's not the WATT numbers you see on the boxes that matter. It's the AMP that the PSU can supply on the rails.

Most power supplies come with decent 3.3V and 5V rails. It's the 12V rails that are low on most generic PSUs.

I would be more concerned with buying a quality power supply.
some 300s' aren't worth the time you waste installing them. On the other hand some 250s' will handle whatever you care to throw at them.
Follow the above advice from the other members as far as the amps on the rails. to many people skimp on there power supply, and spend a fortune on the rest of the system. Then they wonder why it keeps crashing, or blows up taking other parts with it.
