Am I pushing it with an 850W?

post #1 of 56
Thread Starter 
So I'm building a new computer, going for high-end gaming.
I've been around to a couple of forums and IRC channels, and half the people I've talked to are telling me that 850W won't cut it for my build, which is:

CPU - Intel core i5 2500K (which I do plan to overclock)
CPU cooling- COOLER MASTER Hyper 212 Plus
GPU - MSI N570GTX-M2D12D5/OC GeForce GTX 570 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 (May later get another and SLI them)
Mobo- MSI P67A-G43 (B3)


The PSU I've been leaning towards is this:

Am I pushing it getting an 850W PSU?
Some say it's more than enough, while others say it's not.

You have more than enough for that. You could use a 650W and be fine.

Yes, you're pushing it... into standby mode... a good 850w will run that lot and barely warm up. Cheap junk 850s will struggle.

Which exact 850w PSU are you looking at?

You're nowhere near pushing it so long as your PSU is a good quality. A good 750W is perfect for a dual GTX 570 setup, with a good 450-500W being enough for a single GTX 570.

Since you haven't bought it yet, you might as well save some money and get the AX750. And if you don't need full modularity and don't mind a tiny bit less efficient PSU, you should get http://www.newegg.com/Product/Produc...82E16817207003 instead.

Some say it's more than enough, while others say it's going to crash on my and ruin everything.
It's enough. It has enough capacity to power your system with two GTX 580s in it.

Anyone who tells you differently does not know what they're talking about.

You made the right decision coming to Overclock.net.
It's a computer!

AX850? You could run a pair of 580s on that and have power to spare.

I run SLI 570s and a 2500 k on a 750 watt...
Only pulls about 600 (from the PSU) peak while gaming.

You won't have any problem with that psu. Very good choice, also is 80 Plus Gold certified
