Hi, ive got a dell dimension e520. Their PSU is a stock Dell 305W psu. The information about my psu is right here: Code: +5V = 22A +3.3V = 17A +12VA = 18A +12VB = 18A -12V = 1A +5Vfp = 2A Connectors: 24Pin Motherboard and CPU Connector 4 x 5Pin SATA Power Connectors 1 x 4Pin IDE Power Connector 1 Floppy drive power connector Now, i need to get a new GPU since my pc is really old. I already got my new CPU & RAM but my pc is constantly bsod-ing/shutting down cause of the heat. I've looked around the internet what i should get, and i came to the conclusion to get this new psu: CORSAIR TX650 V2. Newegg link: CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.... I need you guys suggestion if it will blow up my pc. It doesnt matter if it fits in my case or not. I will just get a saw and saw my a piece of my case and add some new screws. So that ain't a problem. If anyone can suggest another better or cheaper PSU (good one) please give me an additional info about it. Thank you, Apple.
