a 300w can power a 295 but a 450w can power sli'd 260 (which basically is a 285 on one card.) that makes no sense and screams bs.
How is this BS ?
The GTX295 uses about 214 watts of power, shouldn't be a problem for a 300 watt dedicated graphics psu.
The GTX 260 uses 156 watts or less depending on the model, when run in SLI the power consumption does not double but for arguements sake let's say it does.
2 x 156 = 312 , how would that be a problem for a 450 watt dedicated graphics power unit ?
