How much does the brand of Watt power matter?

I believe I have a 500W for my pc. This is becuase I have a GTX 670.
In a bit I'm going to remove the side and check the brand name.

Will the brand name determine if I can overclock my computer? Or is 500w to low?

Well obviously there are good and bad brands, or recommended and not recommended if you like. If you are overclocking it means that the system absorbs more power so it will obviously need a good power supply. Find out your power supply brand and model and post it here. Then we can discuss further. Also what will you be overclocking?

Brand matters only so much. Good brands make bad PSUs-where some wires can't withstand the current and burn or don't provide the marketed wattage.
But model matters as well as rating. Bronze, Silver, Gold and Platinum rated PSU's are usually what you want to look for.
As far as overclocking goes, you can find out how much power you will need with this algorithm:
TDP*(OC Mhz/Stock Mhz)*[(OC Voltage/Stock Voltage)^2]=CPU TDP+GPU TDP+Peripherals and HDD and Fans...etc.
And then the rating, 80 Plus will provide 80% of the rated Wattage efficiently-but you want more for head room and for a cooler longer lasting PSU.
170w for a 670 and I'm going to guess 125w for CPU, but I'm unsure of what you have. And 70w for LED mechanical keyboard, 2-3w per fan*4=12w. And the extras, I'm going to guess for a non-rated PSU. you would need to have a 450w or more should be sufficient.

PSU= 633186-001 600 Watt Power Supply
If you read my previous post, you would know this is plenty powerful. However for SLI, you'd need a 750w_ bronze or higher rated PSU

Thank you, so I can over clock with Afterburner?
