Hi, I'm a new member, I signed up because I started using alot of different modded drivers due to problems with my BFG 7800 GSOC APG card. However, in the process of creating my profile here, I found out that what I thought was a 400w PSU is actually a 330w. I guessing at this point that this is probably the major culprit, because I'm getting alot of total crashes and restarts whenever I play stuff like bioshock, MOHA, and also getting persistant stutters and momentary freeze-ups in some less intense newer games. I thought it was a driver issue, because some drivers seem to work better with fewer crashes, but no matter which ones I choose, there are problems. I've had the card for 6 months or so and the major problems only started with the newer games, so I'm guessing that they are requiring my system to work harder than my PSU will allow. So, here's my question(s): Is there a high-wattage PSU that would be compatible with my old P4 rig, and could be transferred into a newer Intel dual-core SLI system I plan on building by next spring? If not, what PSU would you recommend, considering that I would have to buy another one for the new rig in a few months anyway? Any advice will be greatly appreciated. I built my own CPU from barebones a few years ago, but there's so much new stuff out there, it's kind of overwhelming. Like I said, I plan on building a new rig soon, so I hope to become a regular around here, I've been checking the forum out for a little while now and it looks like the people here know what's up. TIA for any replies Zeke UPDATE: Right after I posted this, I found PSU sticky...If that don't help I'll let you know!!!
