300W enough for an Ahlon XP 1800?

[thereaderrabbit]

My computer never finishes the start-up posting. It reads '7F' on the motherboard led display and freezes (nothing on the screen). Could it be the power supply?

Enhance ENP-0730 (300W)
Athlon XP 1800
EPoX 8kha+
3xCrucial 2100 256 meg ram
TNT2 Ultra

I've already reinserted the CPU, tried playing around with different memory configurations, and started up outside the case...

PS. Is there an easy way to check if the power supply has enough juice?

300 watt does seem a little low for the 1800+....try at least a 340...

Uh, you don't have an old 250W around you could just try on a lark???

(I had an Enermax 350 or so that arrived D.O.A. So I tried my old 250W
on my XP1600+ and it's been working pretty well. Of course, I will slap
in the replacement 350W as soon as I possibly can, but I don't think the
new core is drawing as much power as the old stuff did. I could be wrong.)

I would be sufficient (no other fancy equipment like 8 fan, 4 HDD....in ur box...just decent ones).

check your video card is seated all the way in.

According to AMD's recommeded PS list, yours is rated to an XP1700, but that's pretty damned close. It should really work I think. Have you tried removing all but one stick of RAM and then if that doesn't work, try swapping it out with the other two? If not, you should try that, along with starting with just the basic items for the first boot; the CPU/HSF, floppy, HDD, video card and one stick of RAM. Get the thing to boot, then add other items one at a time.

damn! buz2b beat me too it 😛
i'm running 300watt antec 303x power supply with a 1.4ghz tbird system, so u should be fine.

Wow, thanks for all the good feedback!

I do have another 300W power supply on another computer that I can try. I guess I'll look into that tonight.

Otherwise, I've tried reseating my video card (which works on my other system), reseating the CPU, shuffled the memory around in and out, and tried booting the board outside of the case (all the while keeping my other drives and PCI cards out). Hmmm...
