Should I get a bigger Power Supply than 650w??

post #1 of 12
Thread Starter 
I've tried those calculators on line and looked around and I'm getting conflicting answers so I was hoping you guys could help.

This is what I have (I only wanted to add another GPU of the same kind unless I can buy something different/better but I read that it has to be the same)

MOBO - ASUS P8Z68-V PRO LGA 1155 Intel Z68
HDD - 1 SSD OCZ Vertex 3 VTX3-25SAT3-120G 2.5"; 1 320GB 7200 RPM and 1 1TB 7200 RPM
GPU - ASUS ENGTX560 DCII OC/2DI/1GD5 GeForce GTX 560 (Fermi) 1GB 256- bit GDDR5 (((Currently just one, but wanted to get another one, does it have to be the exact same one? tnx)))
CPU - Intel Core i7-2600K Sandy Bridge 3.4GHz - I have it OCed at 4.0
RAM - CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 - have these at 1.5v
Optical Drive - ASUS Black Blu-ray Drive SATA Model BC-12B1ST/BLK/B/AS
Tower with fans - Rosewill THOR V2 Gaming ATX Full Tower Computer Case - come with Four Fans-1x Front Red LED 230mm Fan, 1x Top 230mm Fan, 1x Side 230mm Fan, 1x Rear 140mm Fan

Currenlty, I have a 650W CoolMaster Power Supply...

Everything else is sort of standard...2 3.0 USBs, then like 6 2.0 USB's...I bought all thse on newegg.com if I'm missing some info on some of these items.

Thank you very much. I'm basically just trying to play some games at high settings without messing up the entire system.

650w should be more than enough

That should be more than enough, and you can do some overclocking, I would reccomend maby a 750, because later on down the line maby you want to add a second GTX 560, and it does not have to be the same one as long as they are the same model and have the same amount of ram they will work together.

Got it...yeah that's exactly what I was hoping to find out. I'm getting ready to make an order for that 2nd GPU and was wondering if I needed a new Power Supply as well. What happens if I keep the 650 for a while and get that 2nd GPU added? Will it just crash or get serious damage?

Thanks for your help!!!

650w could probably handle GTX 560 3-way SLI. No need to upgrade

650w will work fine with two GTX 560s.

EDIT: Sorry for the double post

650W is fine... Your 650W is not. CoolerMaster have a bit of a habit of lying about their PSUs' actual wattage, especially with the eXtremePower series. The eXtremePower 650W is more of a 500W at best.


A quality 650W unit should handle SLI 560s easily. Not tri-SLI though, or just barely...

Ok...that's kind of what I got from those online calculators. I think most of them spit out about 530-550 W for those settings (with the 2 GPU's). I'm not sure if I messed up on one of them (I added those PCI slots as they show on the MOBO specs) and it went up to like 830W but I'm not sure if it thought that I was using all those PCI's or what..not sure how that works. But, if you guys think that 650W is plenty...then I think I'm going to spend some more money and enjoy battlefield 3!

Oh are you serious? is there a program I can run my Power Supply then? I have everest and some of those others, like cpu-z and something else, i'll have to look when I get home...any of those that would tell me the correct W?

Thanks
