I've just installed a new PSU after the last one in my Dell went pop. The original Dell PSU was 305W and I've replaced it with a standard 400W. I was told the higher watt PSU shouldn't be a problem as the computer will only draw as much power as it needs.
The computer powers up fine but the mainboard fan is very loud and spinning at a much faster rate than before. Is this anything to do with having a higher rated PSU?
If so, will a 300W psu work perfectly fine in place of 305W?
Would appreciate any help/advice given.
