New Power Supply Problem

Jo11ieO11ie · Feb 22, 2014

hi there, I recently upgraded my pc in preparation for my new graphics card the GTX 780 ti. I have booted up my system with the new psu in my new case and for some reason when I turn it on it powers up for about 3 seconds and then it turns of and repeats the process. Can anyone help? its not a short as I have checked all cables.
SPECS:
CPU: I7 3770k 3.4ghz
GPU: AMD HD7750 1gb DDR5
Ram: 16GB 4 sticks
PSU: Corsair rm1000, 1000w 80+bronze
Case: Aerocool X-predator white
Storage: 1tb+2tb hdds
Motherboard: MSI-B75MA-P45

Mobo may need bios update. First thing to try is remove old video card drivers and download new Nvidia drivers for the GTX 780Ti.
If this do not work install new copy of windows.

If psu do not work you need to RMA it.
Next time buy better quality psu.
This is better. Better capasitors and this is more reliable than corsair.

For your build 800w is more than enough.

thanks for the reply, but I haven't got the new card as of yet and im not going to until the computer starts up completely the problem itself is the fact that it starts to boot up for 3 seconds and then stops and continues to do this.

Hi - You should RMA it. A modern mobo shouldn't have an issue with any modern PSU. Also,
are you sure you have the current RM1000? You list it as bronze, the current model is gold efficiency.

Axi is correct - you don't need anywhere near 1khw PSU for the 780ti (or any current gen single GPU),
If you don't plan on adding a 2nd 780ti (then the 1khw makes sense), I'd look for a good
quality 750 - 800w unit.

Corsair sells some very good PSU's, but they also have some "not so good" models.
There is nothing functionally wrong with the RM series. However, that series is marketed
and sold as enthusiast level (a step up from budget/entry level), but they are using budget
level caps in the secondary filtering stage.

Personally, I wouldn't consider the RM series for that reason alone.

Sorry, it is the 80+ gold edition, I got confused! is there any other possible problems which could be causing this which I can try? I'm reluctant to rma it.

Hi - yes, there could be other causes, it does seem like the PSU. You may not have access tot he easiest way to tell (if you do - great), 1st - try that PSU in another computer and/or try another PSU in your computer. The 1st of those scenarios would determine quickly if the PSU is bad. The 2nd could tell you that something other than the PSU is at fault.

Bad RAM will cause a boot loop.

Try booting with one memory module at a time to determine if there is a bad module.
