Will my 650w PSU be enough?

post #1 of 9
Thread Starter 
Hey guys! I am sure you see enough posts asking "Will my XXXw power supply be enough for X." I'm sorry to say, here is another one, because I have calculated I will be fine, but want an "expert" opinion.

So, let me get started by showing you my current specs:
CPU: Intel i5 3570k
GPU: GTX 660ti
RAM: 8GB Mushkin DDR3 PC3-12800 Blackline
HDD: Seagate Barracuda 2 TB HDD
Motherboard: AS Rock Z77 Extreme4
PSU: Corsair TX650M-650w
1x 22" Monitor(Main screen...weird...I know. Don't judge)
2x 32" Monitor(Only used for skype/watching videos...no gameplay...so not too hefty graphics)

I know I want to upgrade to 2x SLI for the GTX 660ti.

I also might want to upgrade to the Intel Core i7 3770k. Let me know what you think about this. Is it work the $300? Will my PSU be able to handle it with the SLI configuration? Let me know!

Thanks,
Kyle

A 650w PSU will be plenty for a single 660ti, Two may be pushing it though.

I already have 1 660ti. Will 2 be too much? With the 3770k?
How about 1 660ti with the 3770k. Should that be fine?

Two GTX 660 ti gpus and a 3770k will be no issue with a TX650, overclock away if you want to.thumb.gif

You'll be fine if you go sli with 2 660ti, with ~150w left over. 3 way is probably asking too much from that psu. Same with 3770k. thumb.gif
EDIT:

Both Ivy cpu's are 77w at stock...3960x is 130w

Odd, i was under the assumption a 660ti used around 300~w of power.

 

Edit: I was looking at total system draw.
