View Full Version : How do you know WHEN you need a new power supply?

Currently I have one DELL p4 1.5ghz with a 250 Watt power supply. It has a gf3, burner, dvd drive, 40 gig drive, sound blaster live.
Thinking of adding maybe another hard drive and possibly a firewire or usb 2.0 pci card.
Should get 400Watt power supply just to be safe?
All that and just a 250 watt? Geez AMD recomends 300 for a 1 Gig for example. I would definitly upgrade that supply to atleast a 300.

How do you know? Well, my last power supply told me when....it said: *POP* *WIZZZZZ* and promptly died. As it turned out, it was a cheapo 250watt ps, and i was running duron 700@900, 4 hard drives, and a burner :(
now it's got a nice antec ps =)

I'd recommend more than a 250 watt power supply with all that stuff in your box...
But how can you tell if your current one is over the hill? Random BSODs... Random reboots... frequent lockups.... pc sometimes fails to start up properly.... hardware sometimes isn't recognized on boot...
And the best one: A strong burning odor. ;)
I'm also wondering if there is a way to calculate how much power you need. I haven't been able to find a "maximum load" number for various components. All I found was 7W for an idle IBM HDD... not very interesting...
I think our questions are answered in this article (middle of the page). The article is about cooling, but it explains the power usage since these two are 100% correlated.
