Power supply undersized?

[85Dave]

Everyone says my power supply will never run my hardware however I have never had a single problem in the 1+ year I have had this PC.

Specs:
- Acer Aspire T180 desktop PC
- AMD Athlon 64 processor 3500+ 2.20GHz
- Stock 300W power supply
- Two 1GB sticks Crucial 240-Pin DDR2 SDRAM DDR2 667 (PC2 5300)
- EVGA 8600GT 256MB 540MHZ Nvidia Geforce Video card
- Vista Business 32 bit

I run a lot of CPU intensive programs such as Adobe Premiere and Cakewalk Sonar Producer and have never had this thing crash on me.
The computer is basically stock other than a new PCI audio interface, the new RAM, and the video card.

So, am I safe running the current 300W supply?

Anyone who tells you the 300W psu isn't enough has been overly influenced by the marketing of 1000W power supplies. Unless you have a very power-hungry processor (A64 is not), many hard drives, an extremely high-end video card, and multiple optical drives, it doesn't take a lot of power to run a system.

If it wasn't enough power, you'd know. The fact that you've been using it for a year with no problems should tell you that you're fine. :)
