can't find psu wattage

[Avik Garain]

Hey, hello to all. So it was just that I wanted to check my psu for its rating. But guess what, there was no sticker mentioning it's wattage. I even examined the psu after detaching it from the cabinet. It was of iball model sps-252 and had 15amperes each on 3.3V and 5V rails and 18 amps on the 12V rail. Can any one tell its wattage.

If it's an iball it needs to be replaced , you don't want to run a card with it.
GeForce GTX 730 - 20A and a 300W PSU minimum

It's a 240 Watt supply which is to small for that card, you want a 300 Watt with 20 amps across the 12 V Rail. I take it your in India? Iball is a brand unknown to most in the US since it was never released for torture testing here.

Really the only rail that counts is your 12V rail. You have 18A (Amps) on the 12V rail. Watts = Volts * Amps... so you have (effectively) 12 * 18 = 216W PSU.

The bigger problem is that according to this list: http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html
Your "Iball" PSU is extremely poor quality. You'll find it way down in tier 5... "avoid immediately"

If you post your system specs (or your current system and the upgrades you're consider), someone will suggest some decently priced alternatives.
