PC Peripherals Budget SMPS suggestion

[Crazy_Eddy]

Almost all PC components draw power off the 12V rail.

12V2 = yellow/black wire = CPU 12V connector = 10A ~ 120W

12V1 = yellow wires = rest of the system = 6A ~ 72W

You're definitely running short of power. Still can't explain why freeing up power doesn't help though. Hard disks with their motors are usually a heavy load during spin-up.

If you can borrow a better PSU from someone, it would clear up any doubts.

I tried a lot to find someone who would be willing to lend his PSU and that too should be higher powered one than mine, but failed.
Hence I think I will just go for a new one. Nothing to loose other than money :huh:

A few questions

1. Should I go for 350 Watts or 400 Watts PSU
2. Options in 350 Watts are FSP Saga II 350W (Rs.1500), Cooler Master eXtreme Power Plus 350W (Rs.1500)
3. Options in 400 Watts are FSP Saga II 400W (Rs.1900)
These are the only three options I have within my budget.

Get the FSP saga 400w

Update:

I got hold of a Supercomp PSU 400 Watts and connected it to my computer with the graphics card inserted. Same thing happened, DVD-RW went into loops.

Where are you located.. If in mumbai, then I have a spare PSU, maybe you can try your luck with this one too

Thanks for the offer buddy. Unfortunately, I live in Pune.

Update:

I used the Power Supply Calculator from here PSUEngine

I entered all the details to the best of my knowledge. It calculated the power to be 312 Watts. I guess this should be the wattage of the PSU at 100% efficiency.

^supercomp is a local company,and it's reliability is very low.There's no guarantee that the supercomp 400w would deliver that much amount of power.

But if you just check your graphics card on your friend's PC,I think it would be better,to know if it's the culprit.

I guess you are confused with what efficiency of a PSU is... Efficiency of a PSU defines the amount of power it would suck in from you AC input to convert the same to that required for you system... It has nothing to do with the output of your psu IMO
