Checking to make sure on my calculations - any advice is much appreciated!

post #1 of 5
Thread Starter 
Ok, with my tax return, I plan on finishing my new PC

The current specs are:

Case: Switch 810
Mobo: ASUS Maximus V Formula
CPU: i7 3770k Ivy Bridge
RAM: Gskill Ripjaw Z 32gb (4x8gb)
HDD: WD Black 1tb
GPU: Nvidia geforce 680
Optical: Asus dvd burner
Cooling: Corsair H100i


The plan is to add another 1TB drive and another 680, then slowly purchase parts and go over to a custom watercooling rig.

I figured a 650 would be enough with the upgrades, will probably get a 850 just for room.

Am I on, or way off with the prediction?

Thanks in advance!biggrin.gif

Quality 650W would be more than sufficient, an 850W would be hurting your idle efficiency. I wouldn't go higher than a 750W.

Thanks for the quick reply.

I've never been too sure on the whole power supply issue so I figured I'd ask. If a 750 will do it that's great, might not have to wait too long to get another hard drive this way.
I forgot to mention overclocking the CPU, but I'm certain it wouldn't make a 100w difference.

Like I said, a 650 would work just as well. 750W is overkill. You can get your HDD even sooner with the 650. thumb.gif

Yeah, a solid 650w unit can power that system. If you want a 750w unit though and assuming your are from the US, then there's a promo that ends today on the Capstone-M 750w that will make it the same price as the 650w version. http://www.newegg.com/Product/Product.aspx?Item=N82E16817182264
