Is my VX550w corsair cooked?

post #1 of 3
Thread Starter 
Hey OCN smile.gif I think my 4 year old PSU might be getting weaker. I'm working on an old core2duo e8500 rig with a 9800gt. One SSD and two case fans. Very little draw right and this setup works with the old vx550w. I got a 4870 for a favor from my friend and tried it tonight and got a single red led on boot up with no display. Messed around and pulled the 4 pin cpu power off of the motherboard and unhooked the drives and got three red leds on boot. All I can find online is the red leds indicate a power issue.

I would like to add that the corsair 550w in question is 4 years old and did a lot of time gaming in a rig with an AMD 970 x4 and a 6950. Alot of the time I could hear the psu fan over the case fans. Made a lot of heat while gaming. Would that have caused enough degradation to make it too weak to even power up an old 4870? I'm pretty sure this cards ok. It came out of a working comp, but I know it's a amp hungry card too. PSU is rated for 41amps on the single 12v rail....I've read recommendations for 30amps at least for the old 4870 1gb.

Any help or tips would be appreciated.

Shouldn't be, especially not with power draw on boot. Retest the old graphics card and all the power connections on everything and the usual stuff.

The fan is loud because Corsair used to not focus on noise and the efficiency is low by modern standards, not because you overloaded it in the past. It should be able to handle more abuse than you gave it.

Just for some closure. I'm pretty sure one of the mosfets popped when I started the machine the first time. It had a universal gpu wb on for most of its life and the voltage regs probably cooked pretty good. Lots of burney discoloration around mosfets on the pcb. One mosfet has what looks like a crack in th side. Im going to check some stuff with a multi meter but I dont have the skill to fix it. Maybe ill find somebody local...who knows.
