Dead Corsair TX650 PSU?

hokken · 14 Jul 2009 at 17:26

Just had a power cut today and the PC won't start up at all now. This happened before but the PC always restarted fine. My PSU is a corsair TX 650, I thought those PSU were designed to cope with this type of situation, all I can think of it is that the PSU died since I checked all sockets and fuses and all are fine, just praying that the hard drive is not damaged since most of my work is on it. Any suggestions ?

Does your motherboard have onboard power led's you can check.
Also remove the PSU and link out pins 13 & 14 on the main ATX connector, connect a fan to one of the molex connectors and start the PSU, hopefully this should start the psu and the connected fan.

Hmm, maybe you had a power surge before or after the powercut that's damaged a fuse or component inside the PSU?

change the fuse on the power cable

All outside fuses are fine, there is no lit up LEDs anywhere on the mobo so I suspect the PSU is now resting in peace which is a bit disappointing for an apparently good quality product.

Have you tried a different malns power cable. Its sometimes difficult to tell if the fuse in there is blown.

have u actually tried a different fuse in the mains poiwer cable?

Yes I tried another power cable and the result is the same.

Annoying... I can only guess that you had some kind of surge that killed it.

Even the best products go wrong sometimes.

did that power cable have the same size fuse in as the original?

It is a cable that is on my second computer, a standard one.

well could you check they have the same fuse?

the number of times some one has given me a cable with a 5A fuse instead of 13A is too many

A 5A fuse would be ok for a 650w PSU.

The PSU may have died, but hopefully protected the PC from damage.

But do what RJC suggested and try the PSU on it's own.
