My graphics card manual says it need two 6 pin PCI-E cables and my PSU has only one. Although, my graphics card comes with a few of those cables with one end being the 6 pin PCI-E connector and the other end looking like three big pins. Would I be able to use that to power it? Where would I plug that cable in? I really hope I don't need to buy a new PSU with two of those connectors. Please help me as soon as possible. Thank you.
Since you're running B75 chipset, I suppose you're running Ivy bridge CPU with TDP of 77 watts. That graphics card will use around 170-180 watts. That's around 260 watts on 12V rail.
Then you've got some hard drives running on 5V rail, 20-30 watts. 40 watts more for chipset/RAM. You total system power consumption will not be above 350 watts, so it should definitely be enough. That is very decent 430w unit, it will work without any problems.
Just use the adapters given so the card can have enough connectors . It must have two to function.
correct me if I'm wrong, but isn't the chipset/RAM running off the +12v as well?
Yes it is. After seeing my graphics card manual say my PSU needs a minimum of 500 watts, I am sure of this now. I am just kind of upset that I have to send the old PSU back and buy a new one. I don't understand why someone would recommend that PSU to me after I showed them all the parts I was going to buy. Anyway, I want a recommendation on this PSU.
I really hope your're right. The last and only time I ever asked for advice on my PSU, someone told me to buy the 430 watt one I have now. So do you think it will last about two years along with the rest of my computer?
EDIT: I forgot to add, this is my first time building a computer and my first time looking at the parts. When I opened my non-modular 430 watt PSU, I noticed how one end of the cables are attached inside the PSU. And I just looked at that modular PSU and I noticed the cables are not attached inside the PSU. So I just wanted to ask, is using modular PSUs fairly easy? I really hope they are and I hope you are right about the one you are recommending for me.
to be honest thats the psu im using right now. im quite pleased with it.
and it should last at least 3 years, thats the warranty. although i would expect many more years than that.
Actually don't worry about the question I added in the edit, I'll figure it out. I am taking your advice and buying that PSU. I just really, really, really, really hope that it will be a good PSU and I won't have to return it back like I have to do with the one I just bought. Thank you for the advice and I will select your answer as the best. Goodbye.
