Power Supply Is It Enough !!!!!!!

[music_lover]

well i have a P4 1.5 GHZ machine a DFI i845 MOBO
Got a 4x agp and 3 DIMM SLOTS one occupied with a SDRAM Stick(256MB)
well now i wanted to upgrade to a new GPU card and some ram
probably gonna fill up all the remaining slots with 2 sticks cause these SDRAMS are gonna be DINO'S OF THE 21ST CENTURY
and i will be upgrading to a FX 5200 card (gainward) And 2 Sticks Of 256 mb rams

my question is that i have a "300 w" SMPS as of now all i have is a riva tnt in that AGP slot a 5400 rpm HDD and a Cmedia sound card in a PCI slot and as cdrom a cdrw
well wanna ask if is this SMPS sufficient enought to run the machine after the 2 upgrades i.e GPU CARD AND RAM
please do reply
thanks

The power supply should be sufficient. If you notice that your machine starts to crash and get exception error, then that's the time to replace the power supply. I have a PIII 800 machine which has a 300 watt power supply, and the power supply still have enough juices to power the following:

6.4GB IDE
1gb SyQuest Sparq IDE
Hitachi DVD-ROM IDE
18GB IBM SCSI
18GB IBM SCSI (2nd drive)
18GB Fujitsu SCSI
Yamaha CD-RW SCSI

The board is a Asus P3V133 with 1 AGP, 4 PCI, and 3 ISA. All the PCI slot are used up, the AGP is used, and 2 of the 3 ISA are filled (the 3rd ISA is shared with a PCI). The 300 watt power supply is still going!

i bet the voltages fluctuate a fair bit though. I also think it wouldnt last too terribly long at full load. The PS in my computer was limiting me when I was working on overclocking my computer to the max. (AMD 2500+ @ 2520 watercooled) The voltage rails just werent steady enough with the 400 watt supply I had. I bought the Antec 550W power supply and it allowed me to go almost 100 mhz faster. Now to overclock this Athlon 2500 Mobile processor I just received. I am shooting for 2600-2700 actual mhz

IMO it's sufficient for the upgrade.
