Hey all,

I've been having boot issues for the last couple of months. My PC would fail to power up, no beeps or lights. Then after a bit it would start & as long as I kept it plugged in to the surge protector it was turning on every day.

Things got more flaky in the last 2 days & finally it would not start at all. PANIC! Ok, methodical check list testing time & I get to the part where I have to try another PSU. Ah! Sweet relief, it works again:P

My question to you & is this: Would you be happy running (no OC) an i5 2500k, one 5850, one SSD, one HD plus peripherals from a Corsair CX600 for a while untill I get a new PSU via RMA? The PSU that appears to have croaked is an AX750.....

There was no drama with the PSU, no sparks & smoke but it's definately out of life. So my second question is: Do you think external factors might have affected the PSU's demise - by this I mean stuff like my mobos super charge feature, power phase configuration - even the orientation of the PSU (case is RV02 & mobo MSI GD53) as I want to avoid any future problems.

Cheers in advance!
 
I would have thought that a 600W Corsair would have had no issue with that list of parts in the slightest. The TX750 could just be an unlucky unit, there isn't really any way to know that I can think of. Orientation shouldn't matter, but if someone was to correct me I wouldn't complain, I've never heard of it mattering...
 
I'm running 7970 oc + i5 stock with 620W so you would be fine.

PSU orientation doesn't matter, even if you install it in the wrong direction, at worst you'll just screw around with air flow of your case.

PSU is a matter of luck and QC. I've had some blowing up after 3 days, and others failing after warranty expired. You're good if the PSU dies under warranty AND it didn't destroy any other components :p

Take any computer's power supply. Short all power output wires together. Power it on. Even that does not harm a properly constructed PSU. In fact, Intel even defines how thick a wire must be to perform that short circuit test.

Nothing on a PSU's load can harm any properly constructed supply. Even shorting must not damage any supply; including those in the original IBM PC.

You have defined classic infant mortality. A manufacturing defect. Most failures are manufacturing defects. Others do not appear for years. Yours was apparent only when the load made an existing defect obvious.
