Thermaltake 1350w PSU troubles...

[RandyFolds]

I tried to pop my 1350w PSU into a rig and now the computer won't boot. It was working when I boxed it up, and hasn't been subject to any drops or anything other than sitting. When I short the green and black leads, the fan fires up, and when I have it installed, it is supplying power to at least the mobo, as some LEDs light up when I hit the soft-touch power switch on the mobo. When I hooked up my Antec 750w that was originally on the system, everything works fine.

Anyone have ideas as to how I can troubleshoot it, or should I just RMA it? It weighs a ton, so I'd like to avoid shipping it if possible, and I just can't imagine how it broke itself sitting in a closet. I don't have another system to test it on right now, but I can't imagine it would be any different if the original PSU is working fine.

TIA

I would RMA it and see if it fits in any of the flat rate boxes. Or use a multimeter and test the voltage of the 24 pin and 8 - 4 pins.

I haven't found my multimeter since moving recently, but I'll do some digging and give it a shot. It's in one of those boxes somewhere...

Good call on the flat rate...I guess I can just cram it in and let the PO worry about it ripping through the box.

Thanks.

NP, i had 600W ultra from 2003 that i thought i could mine with. Big mistake. i was getting behavior like you where it wouldn't boot with that psu but the newer 420W booted fine. Turns out it was bad after i tested a few leads with a multimeter. "Wow, i'm not getting the 12V that i need." Not really the same thing but the multimeter confirmed it was time to toss the 600

The 1350w is pretty new, and thermaltake makes a decent PSU. I never drew more than 800w at the wall, so it's not like I was beating the hell out of it. It was running stable until I disconnected it, so I am stumped as to what could have gone awry while it was just sitting.

Are you sure it isn't the motherboard?  Does motherboard post when using a different PSU?

[RandyFolds]

No, and it runs like a champ as far as stability. I don't really know what else to go by...

FYI, Thermaltake does not make PSUs, not a single one. They contract the PSUs out to oem manufacturers. The Thunderbolt series is made by Sirfa. Your Toughpower was manufactured by CWT.

Do check the voltages with a multimeter and inspect all connectors visually to make sure no contact was damaged during the installation.
You didn't forget to plug in the 4-pin ATX/ 8-pin EPS connector, did you?
