My PSU fan had started making lot of noise. It is a sleeve based bearing Fan. I tried using sewing machine oil to silence it, it was running without noise for a couple of months and the noise started once again.

My current PSU is : Cooler Master Extreme Power 600W Power Supply

1) Can you please suggest whether I can replace the fan alone, if yes, can I buy any 120mm Fan or what spec should I check ?

The existing fan in the PSU is:
Model Part Number: AD1212US-A71GL, 12 Volts, Current 0.5A
Service Unavailable

2) If I have to replace whole PSU, can you suggest some good PSU for my current PC config below. Budget: Rs.3000 to 5000 (should be able to support any future upgrades )

My PC Config:
Processor: Intel E8400
Mother Board: Abit IP35E
RAM: Corsair 2*1GB(800MHz) - TWIN2X2048-6400
Graphics Card: Sapphire HD5670 1GDDR5 PCI - E HDMI/DVI-I/DP
HDD: Western Digital Caviar SE16 320GB 7200RPM 16MB (WD3200AAKS
Cabinet: Cooler Master Elite 330 Computer Case
DVD Writer: Samsung SH -S203 SATA DVD RW or Lite - On 20X With Light Scribe
UPS: APC 650VA

It's not advisable to open a PSU as there is a risk of electric shock even when it's unplugged from a power supply.
I don't know anyone who changes their PSU fan, they just buy a new PSU, that's what you should do.

I have already opened it twice and oiled the fan to silence it. Ofcourse, not being aware of the potential shock from capacitors inside. :( 

I am considering to buy a new PSU, may be will repair the fan keep the CM as standby PSU.

I am in a dilemma between: Seasonic S12II 430 Watts PSU & Antec Antec VP450p.

My requirements are the PSU:
should be able to handle seviour power fluctuations, without burning out/ blowing up capacitors inside
should fit into my current cabinet Cabinet: Cooler Master Elite 330 Computer Case without problems
should be silent. I guess the Seasonic has a ball bearing based fan.. will start making noise sooner ?
should survive at least the next 5 years

Seasonic S12II 430 Watts PSU is better quality.

Antec is decent though.

I have decided to buy Seasonic S12II, but questions below

1. will Seasonic creating problems with my UPS: APC 650VA.
I read somewhere it would create problem due to output waveform is "Stepped approximation to a sinewave". The UPS Output Power Capacity is 390 Watts as per APC website

2. should I buy 430 Watts / 520 watts, considering I will not use more than one graphics card / overclock.

3. My current PSU "Cooler Master Extreme Power 600W ", though labeled as 600W as per reviews it is only 450W. Haven't faced any problem with the UPS, except one or two abrupt power outs
