Hello everyone! Let me give you a little run down of my situation thus far: A few days after Christmas I purchased a brand new GTX 260 to replace my pathetic 7600GT. However, upon arrival, the sheer size of the card blew my 7600 out of the water. It sadly covers the majority of my SATA ports, FORCING me to squeeze the cables just underneath the card. However, this isn't the issue. Two days ago my computer was running just fine and I was browsing the internet when it shutdown unexpectedly. Upon trying to reboot it I received no POST or Monitor display, and my video cards fans had stopped spinning, which led me to believe my BRAND NEW GTX 260 had just failed on me. So I swapped it out for the 7600 and rebooted. All the components inside seemed to be powered: LED fans, CPU Heatsink, GPU, HDDs, etc, but there was no monitor display and none of my USB devices were on like they usually are upon booting the system. I suppose my QUESTION is did I blow my 550w power supply when i introduced this goliath video card? I know that 550w is supposed to be sufficient but I'm not completely sure. If you need any more information regarding my issue, ask! Any help is greatly appreciated!

Here's mah specs:
Windows Vista Pro
MSI G33M Mobo
Pentium D 3.0
Evga GTX260
2x1gb Patriot somethingorother, 2x1gb G.skill DDR2
Rosewill 550w PSU
Pwer supplies do go bad. If you have an old motherboard and a voltmeter you might be able to test the power supply.
But, more often it is the motherboard that goes. It has more things that can go bad and is easily damaged.
Is it under warranty?Yeah I believe it's still under warranty. I only purchased it a few months ago, so it better be! It was pretty chinsy-cheap too. Maybe I shoulda shelled out a little more cash for the MoBo, because now i'm stuck with this dwarf MoBo and a massive card. From the information i've given should I RMA my MoBo or check into my power supply? I don't have a spare lying around and would rather replace my MoBo first before buying a 600+ watt PSU.Return it immediately and if they are open to it put the credit towards another board other than MSI...
In the meantime see if you can borrow another PSU to be sure.UPDATE!: I RMAed the MoBo and card, put them in, worked like a charm, but then same issue. I just would like to confirm that this points at a power supply fault, correct? This is considering a new video card and MoBo not working together is caused by this crappy power supply, not broken parts.Maybe it Has something to do with Your Name NEVER Know Now Do Youu
Alright I'd like to just confirm what is currently wrong with my computer. My Video Card fan is not spinning, and this one is brand new! Most of the components are powered except for my case fans which I have to unplug and replug in to get to turn on. There is no display, no POST, no beeps, etc. I believe my power supply is a bit low on amps of the 12+v rails, but I cannot tell if my power supply is the reason my card is not turning on/FRIED. Any suggestions? I'm currently considering replace my 550 watt with something a little more like this http://www.newegg.com/Product/Product.aspx?Item=N82E16817139009 but if the power supply is not the bad egg in this batch I'd like to avoid dropping $140 on a new PSU.I 'm just wondering if the size of your new card isn't causing an overheating problem due to perhaps a constricted airflow in the case. Overheating could have damaged the processor or the board.......power supply is always a possibility with the new card drawing more power...........minimum system requirement is a 500 watt supply for that card (their website).............you could be light in wattage with everything running.Well I don't really think air flow is a big deal, but then again, my case is quite a mess. (see attached photos, rofl) If that's the case just what can I do? Does that mean that I just fried another board after just RMAing it? That's embarassing.

Here's the fotos, yuck:

Note: The close up is to emphasize just how little access I have to my SATA ports. My SATA cable is the blue blob, and yes, it's upside-down. Hope using the ones underneath the card aren't causing the card to be slightly dislodged or something. bump?
