Overheating the Power Supply?

Hey all... I have a P4 1.7 with a DVD/CDrom, CDRW, 2 HDD's and a floppy, along with 7 (yes, SEVEN) fans... lately, my PC has just been shutting down out of the blue, then re-starting... all by itself, no warning... I'm running a 350Watt power supply... someone mentioned that the Power Supply may be causing the shut-downs... does this sound right? I'm gonna try disconnecting the floppy drive, one of the HDD's, and maybe a couple of the fans... it seems to run around 34 degrees celsius most of the time, so I think the 7 fans may be overkill.... any input? Should I get a bigger power supply?

7fans arnt really a big load... they only draw a few watts each.
Tell me, when you PC is running at full load, is the PSU putting out alot of heat?
And you should download Motherboard Monitor and check your 5v and 12v voltages... dropping voltages is a classic sign of a struggling PSU.

Hmmm. Usually the limits are around +/- 5%... so yours seem ok. Tell me, does the 12v reading change much between idle and full load?

Basically any program that runs the cpu at 100%.
Sandra benchmarks, prime95 torture test, mp3 encoding.

try anything while watching the voltages.
A fluctuation from 11.76 to 12.1 sounds a little big to me.
