Hey, I recently got a cool mATX case and decided to put my main rig in it that just happens to have a mATX mobo. All went well but I had to sit my ATX PSU outside the case because it only takes mATX PSU. This isn't very practical but after having a look at the mATX PSU on the market I wasn't very impressed with the 300w or lower choice. Maybe I'm over estimating what I need because of the 550w PSU I'm using now Could I get a Micro ATX power supply to run this: 1. AM2 X2 4200 (65w) OC'd to 2.42GHz 2. HHDs (1 SATA 1 IDE) 2. 512s of DDR2 800 2. 60mm fans 1. optical drive 1. 1xPCIe WiFi card future upgrades: another 2 512s of DDR2 800 maybe a PCI TV card and a 8600GTS or a 2600XT (waiting on the benchmarks) Will be OC'ing the graphics card. Any thoughts/ideas will be appreciated, Thanks.
