My PC: Model: Sony VGC-RA834G and it has a unique power suply setup in the way the power supply mounts into the case. The power supply it came with it only a 285 watt.
I have some photos I took to show you guys so you know what I'm trying to explain. On the power supply, it has 2 bolt heads that stick up, and these two bolt heads are what holds the power supply into the PC Case (kinda like, you just move a lock, and then the power supply can be quickly taken out kinda thing).
My problem is, how do I upgrade to a new/bigger power supply? (Pretty sure new power supplies won't come with the bolt head looking things to mount it into my case? (And I tried unscrewing the bolt head looking things from the power supply, but I'm pretty sure they aren't meant to be removed (don't seem to want to unscrew).
Any help would be very appreciated. Here are the photos below (links are to photobucket).
