is 900w PSU enough?

[Matriox]

Hi I have almost completed my pc build but I don't know if 900w will be enough to power my system.

My system includes the Fx8350, R9 290x Sapphire(3 fan gpu),Water cooler(120mm fan,1 tb hdd, and thats about it no optical oh and 8gb 1866Mhz G.Skills Rip jaws

If it is not enough to power it please provide a better wattage, Thanks.

What exact PSU is it?

If its a nice one Corsair or SeaSonic then yes, But if its one of those that catch on fire at 50% load then no..

[TheNinjaNextDor]

It's way more than enough.

[Izaya Orihara]

You could power a R9 290x's Xfire with a 4960x oced balls to the walls of 850 Watts. 

[SAV1OUR]

you would be fine on a 600w

[jlangford.9]

A nice 650/750W would be nice. The new EVGA 750/850Gs are nice, Seasonic makes some nice 650W psus. 

[GamerDude]

Saying you have a 900W PSU means nothing w/o stating the brand and model, if you have a generic PSU rated at 900W, you ought to be worried....but, if you have one from a known maker of quality PSU's like Seasonic, SilverStone, XFX, Corsair and the like, you're safe.

1. You won't need 900W for a single GPU system.

2. Please tell us which PSU you have or are planning on getting.

A 550W-600W power supply would be more than enough to power your system. What is your budget and where are you buying from?

It is a coolmax zu-900b series 

[loccilucas]

yes. 900w is more than enough

[deVIZtation]

Replace that psu.

[PingPangbv]

As long as you get a quality brand PSU you could get away with something like a 600W PSU. Please have a look at this:

[Prokart2000]

dont get that coolmax psu

[daemonowner]

Coolmax is crap. They aren't the lowest tier of crap, but they haven't managed to become better than crap. Please oh please change that PSU.

There are some other reviews of Coolmax units on JonnyGuru.com. Most are pretty unimpressive and some exploded. The Coolmax CUQ-1350B was actually pretty decent though (for 2008), scoring 9/10.

It is a coolmax zu-900b series

I like that video but my gpu was recorded at 300w at maxed out because it has 3 fans built in, but I may crossfire the 290x so I may get a EVGA/corsair 800w+

I only thought it was good because it was 80+ bronze and i saw good reviews about it

[toms94z71]

That would be way more than need 600 watt would even be plenty, I would only go with an 850 or 900 or more if you are planning crossfire in your future. Also I have heard plenty of horror stories of lower end psus destroying good systems. I got an 850watt silverstone in my system, going to run dual 780ti gpus eventually. You got to think a psu is like the heart of your system, it supplies the blood aka electricity to the everything in the system and if you got a bad one you won't live long especially if you are getting worked hard and that weak heart is pushed to far.
