PSU question

[SeventyPointThree]

I have a Keian PSU that I bought in Japan.  It's a 1000w 80 plus gold.  The only review I found online said It's not that reliable.  I'm thinking about swapping it out.  I'm not sure on how much wattage I need at a minimum.  Any help would be appreciated.  

 

Specs:

 

Intel i5 3570k  overclocked to 4.1 ghz

 

Asus Sabertooth m/b

 

2 8GB DDR3 Kingston HyperX Blu RAM

 

2 MSI GTX 770 SLI

 

WD green 1.5 TB

 

120 GB SSD, 240 GB SSD

 

Sound Blaster ZxR

 

1 Blu Ray Drive

 

NZXT Kraken X60 with 2 140mm fans 

 

3 200mm Fans, 1 140mm fan,

750W would power that, but I'd personally go for a nice 850W for peace of mind.

[Rorgash]

750W should easily cover that

[DarrenP]

I would say 850W quality power supply. I would think you'd be cutting it to close and would likely reduce lifespan of the PSU using a 750W. 

 

My rough math:

GPU's: 230W x 2 = 480W + Overclocking So let's say 520W to heir on side of caution.

CPU: 77W + OC (Give or take) = 100W 

Motherboard + Extras = 150W -Give or take, with peak on HDD's and spin-up

 

That's  760W Roughly. 

 

In the motherboard + extras includes any peripherals, and anything you could ever want to plug into your computer. Just being conservative, better to get a little higher than cutting the line.

I recommend corsair 860i watt psu

[Zade_95]

Any good quality 80+ something thats 750w or higher should do the job. Make sure its a reputable brand and has enough on the 12v rail though To be safe maybe go a bit higher tho. AX860i like Nick above me said would be more than enough

[WoodenMarker]

Minimum is a solid 600-650w psu. It's probably cheaper to just get a decent 750w though.

Thanks for the info.  I was thinking about the Corsair RM850

Overkill. The rm650 would already do and most people would recommend getting the rm750 for headroom.

 

Edit: Just noticed.. why do you have a 3570k only at 4.1 ghz with a Kraken x60? You should get at the very least ~4.5 ghz if not more with that much cooling and a sabertooth.

[SeventyPointThree]

I was able to get it to 4.4 ghz stable.  I lowered the clock a little bit because the environment has been warm.  My apartment has poor ventilation and my wife gets mad when I open the windows in the winter.  I'm new to OC'ing so I just figured I'd lower it a little bit.

What makes a PSU SLI ready.  I notice some PSU's advertise that.

Having enough watts to support more than one GPU . Please use one of the links I provided in the future when calculating PSU wattage.
