Hey I've overclocked my Sapphire HD 6450 as I want to play mass effect 3 on my old computer and I wanted to know if my PSU can handle the extra wattage.

My stock settings are

Core 625mhz
Memory 667mhz
Voltage .975v

The settings I am running are

Core 750mhz
Memory 800mhz
Voltage .980v (it seemed a little stabler with the small voltage increase)

I highly doubt this is a viable source of data but a CPU oc calculator says 23watts over the original 18watts. (which is probably more or less the increase In wattage I'm getting anyway, "the reference card has the memory at 800mhz anyway" which is rated at 18 watt

My PSU is an OEM 250watt which is 5 years old


I highly doubt I have much to worry about with such a lower wattage card anyway... but I'd rather ask

The card is a low profile passive cooled card with an added fan (I had overheating problems, not a problem now "30-50c vs 60-90c")


Thanks

Need more info on your setup, but 23 watts isn't much of a load on the PSU...Although, if the PSU is rated at 250 watts it is pushing around 175 watts if it is 70% efficient...So you do not have as much headroom as you thought....Like I said if you provide more info on the setup it would help
