Upgrading my graphics card?

[Brosive]

Sorry for bumping, I didn't feel the need into making a new thread. Anyway, I found out that my motherboard doesn't support power supplies that are more then 450 watts. While searching the internet I read somewhere that I could put in another power supply that is under 450 watts and that would work. Would that really work, I really need this new graphics card.

I want recommend followings Nvidia GeForce GTX 690, Nvidia GeForce GTX 680, AMD Radeon HD 7970 and Nvidia GeForce GTX 670.

That question has already been answered, I need to know if I can go and put in a second power supply that is 200 instead of buying and replacing the one in their with a 600 watt one.

That does not exist. Motherboards do not have power supply limitations. Even if you had a 20pin power supply it would work at a 24pin motherboard. And no you can't have 2 power supplies just like that.

For a GTX 660 and a non overclockable i7 you don't really need anything more than 550-600W as other said previously. When it comes to psu's prefer Corsair, Seasonic and Thermaltek. If you get one from these brands it should also have a good efficiency (80 or more).

So, just get a 600 watt power supply?

Well this is an OEM case so you should be careful with some things. Some years back HP would ship computers with some custom longer power supplies but I don't think dell or anyone does that anymore. The PSU is 460W which might be ok. Also the system must be very new right? It has Windows 8 and new gen graphics cards.

Edit: Nah, the 7570 is very low-end gpu so it must draw way less power. Yes if I were you I would go for a bigger power supply too. 550-600W should be just fine for even a 680.

Edit 2: Also depending on how well ventilated your system is you should choose between a blower or a oper-air style graphics card. If your system is not well ventilated go for a blower which exhausts the air from the back. Open-air are non-reference cards, maybe preoverclocked, with better cooling, more quite etc (usually)...

Reference(blower):

Custom(open-air) <-- prefer this unless the case is badly ventilated:

I actually already bought a new case:

and this is the graphics card that I am getting:

and is this a good enough power supply:

Also, would I need more fans to cool my system? If so, how many and what type?

Your case has one blue 120mm front fan. You could add another blue rear 120mm one so that the air would insert from the front of the case and exhaust from the back. However, if you don't do any overclocking and the cabling is nicely done I don't think you need more as they make more noise that way.

Alright then, thanks for your help.

Sure, if you need any help building it or other post-install issues just post!
