DEAD-ON-ARRIVAL: is there an indicator besides the I/O switch to determine if PSU is ON or OFF? My old PSU had an LED that lit up if PSU was working.

Just plug it in and flip the switch, should be all it takes, if it isn't working Amazon and Corsair both have great customer service (in my experience) so it can be replaced no problem. Do note that if it isn't hooked up to a motherboard or shorted (at your own risk) it won't actually put out power due to a connection detecting pin. It is possible to short said pin and plug in a fan or something to test it but I wouldn't necessarily suggest that.

Here's a 2 minute official Corsair video explaining how to test the PSU with a paperclip.https://www.youtube.com/watch?v=5FWXgQSokF4

Nope, just power switch and fan rotation. If you are uncertain if it's PSU or motherboard failure, you can always try to manually turn on the PSU. If you look at the ATX power connector, there's a green wire that if shorted to a black negative wire, will turn on the psu. At that point you can see if the fan activates, test the output of molex connectors with a multimeter to verify proper output.

I'm not quite sure how you would go about doing that but I would say check your CPU and GPU temperatures while under stress first and make sure nothing's overheating. As far as PSU failures go you should rule out everything else first. A defect in the PSU is always possible but unless it's really old I would say chances are very slim.

Are the fans spinning when its powered up? Make sure the video card is hooked up correctly and it has power. It may be dead on arrival

Is the red led power-on indicator lit?If so,your problem is most likely with the device.A volt-meter would help.

Robert the only part that may help you is the power supply tester, part of your power supply may not be working even tho things power up. Martin

Something is certainly messed up. Few minutes tops.. It could be power supply..jeez... Dead Upon Arrival. I've had good luck with mine though....

I am having this problem as we speak. Seagate just finished telling me that they believe the power supply is dead, and the warranty department says we need a new one. Unfortunately, they don't have any in stock, and they "don't know" when they will have then again... maybe a month, maybe more. What the HELL am I supposed to do to access my data until then? DO NOT buy this stupid thing. I had maybe 10 hours of use on the power supply before it died. Seagate told me immediately that the problem was the power supply, so they absolutely know this is an issue. GGGGGGGGGRRRRRRRRRRRRRRRRRRR!

if the cables are connected right, and the motherboard is not defective, you will see the red led light the minute you switch the psu switch on.

My PSU burned up when I turned it on for the first time. It's not a brand-name unit.

No idea, but would guess the blue light going off could indicate failure. I would try putting a new doc on CPU - then check next day to see is it exists in the image in Clickfree.

John, I'm sorry. It turns out that the problem with my computer was unrelated to the card. As for upgrading your PSU, I'm not sure if I would be able to give you useful advice.

I've had mixed behavior on mine. The LED on the first port works as expected, each of the other LEDs have been irregular. I've noticed that if I restart my PC, the LEDs don't always come back on for ports that are enabled (even though the ports may be working). Other times I actually have to toggle the port on/off to get it working after a PC restart... and the LEDs may or may not come back on to reflect the status. Short answer; mine acts weird too.

That is an old problem that has been fixed. I bought this PSU about 6 months ago and have a Gigabyte GA-X79-UP4 and I've never had a problem. The PSU has been working perfectly.

I have only installed to 500 watts or more. Probably not enough power from PSU!

I made sure all the connections were the same (marked them) as I took off the old power supply and mine started right up. Maybe you have something connected incorrectly to the motherboard that relays power from the start button, good luck.
