I currently have a Corsair TX750w 80+ Bronze power supply. I plan on getting a HD 7990 by next month.I will be selling my current card to my friend as he is building a new PC around the time I buy the 7990. I just need to know if my PSU is suitable enough to handle running this card.

My specs:
FX-8350 4.6GHz
Gigabyte-990fxa-UD3
Corsair Vengence 8GB 1600MHZ
Sapphire 7970 GHz Edition
1T Western Digital HDD
Evo 212 Heatsink
3 200mm fans
1 140mm fan
Corsair TX750w PSU 80+ Bronze

Thanks

Yes, that PSU should be able to handle those components fine but it may be cutting it close.

If I'm not mistaken, HD 7990 needs 3x8 pin from PSU, right?
So yes, your PSU can handle that monster... :)

According to this PSU calculator it should work however it will be close. This is a rough estimate but should give you a good general idea. I think these power supply calculators take lower quality supplies into consideration. You are using a good supply so it should be able to handle fine under heavier load.
