Hello, I have a 500w PSU with 1tb 7200rpm hard drive, 500gig 5200rpm hard drive, 1 120gig ssd, 1 radeon 7850, 2 4 gig sticks of 1600mhz ram, 1 200mm fan, 2 120mm fans, and a phenom II x6 1035t, after replacing my Phenom's stock fan with a Thermalright True Spirit 90m, it fails to show anything on my monitor.

I first thought it was the graphics card, the fan runs, I understand this doesn't mean it is the graphics card, but I don't know how it could.

My next first thought was the PSU, I have a lot of stuff, maybe it stopped working? Albeit, all the fans spin, from my graphics card, to the new cpu cooler, and even the 3 case fans and PSU fan.

What is going on, could I get some assistance with this? I need my computer to work and I would appreciate the help. Thank you

If it's not a PWM fan then you have no control or view in it. 500 watts is quite low for a build like that. I would really recommend 650 watt or more. I just stick with the 760 watt to be safe and have a lot of headroom. Only buy Seasonic or Corsair.

See that makes sense. However I disconnected two of my fans, and my 500 gig drive.

But it doesn't make sense, because I use to run it with everything the same except a stock fan and it worked fine... I agree, I have too much stuff, but why would it crap out after installing a new fan? Does this fan just consume more energy, like significantly? Or did trying to start it up with everything installed kill my PSU?

Not only watts matter but perhaps your PSU can't deliver enough amperage to certain components. Link to your exact PSU?

So after about an hour (could not find my little thermal compound syringe for the life of me) I removed the fan, and reinstalled the CPU after cleaning it a lot better. I had A LOT of thermal compound on there(thermaltake provided 2g and I thought that should have been just the amount needed, silly me). I also think I had the fan facing the wrong way, the instructions did not tell me where to face the fan until I noticed little arrows pointing to where it should be facing, now my system is running so much cooler now, I have all of my fans on medium, all three hard drives, and even my graphics card. I know it does seem like my system is running a lot but I don't think I should need a new PSU should I?
