i'm planing on buying a new computer soon
here's the specefication :


CPU : Intel Pentium IV 2.6C GHz HT 512K 800MHz Socket 478 CPU BOX
Motherboards for Intel : Asus P4P800 Deluxe Intel 865PE Motherboard (HT,FSB800,S-ATA,RAID,1394,5.1 Sound,3Com G-LAN,USB 2)

Video Cards : Leadtek Winfast Geforce FX 5900 TDH MyVIVO 256MB DDR Retail Video Card
Floppy : Samsung Black 1.44MB 3,5" Floppy Drive
CD-ROM / DVD-ROM : DVD-ROM Liteon 16/48 - Black !

Speakers : Altec Lansing ATP 3 2.1 Speakers
Cases : Compucase-HEC Midi Tower CI-6A19 BLACK Front USB 300W Case
Cooling / Modding : Vantec Stealth 120mm fan

is a 300W PS enough for such a computer ?

With that CPU and videocard I will never use a 300W especially not e generic... both use lots of power so I recommend atleats 350W but even then it is probably running on its max... 400W+ would make your PC more future proof.

My CPU fan spins so fast that it creates a wormhole

You can get a high quality Fortron 350W power supply with over 400W peak output at Newegg for only $32. Better than an Antec or Enermax 350W unit, and cheaper too! So why risk using a 300W (anything) when such a good supply as this is available for so little money?
