PSU Recommendations

[confuzzedintelguy]

Ok well a new pc is in the making I will be using a i7 5930K in the rampage V along with 3 x r9 290's (probably will be aquiring a 4th) I need a rough guess as to watt requirments.  Right now I have a RM850 and the thing is great but i cant say i trust it with 3-4 thirsty 290's and a thirsty 5930K but i don't want to overdue it either i was guessing around 1200 watts but wanna get some opinions.

Best you'll be looking for is a 1300W EVGA Supernova G2.

 

You can usually find them on sale for $169.99 with a $20 rebate ($149.99 after MIR) every few months. It's one of the best PSU's out there, and a 10 year warranty to boot. The last sale just ended at Newegg.

I would second that.. 1200-1300w... wow... 3 290's - and here i am happy with my ONE 270 lol  

 

hope you are liquid cooling!

I'd be tempted to go for the EVGA Supernova G2 1600W personally and especially so if you are serious about putting a forth 290 in there and intend overclocking.

The XFX is looking like it will handle the load for three without a problem however I did actually decide to get a 4th, 1600 seems like a little excessive to me though, don't get me wrong I do appreciate all the feedback! By chance do you have that 1600 watt monster? I'm thinking something between the 1600 and the 1200.

 

Maybe? http://www.newegg.com/Product/Product.aspx?Item=N82E16817153154

 

As for cooling it will be water cooled but i have a external box built just for the pump/fans so the main rigs power supply wont be powering any of the cooling solution. 

 

Its funny how much the price goes up for a couple hundred more watts.

The 1300W EVGA Supernova G2 that El_Capitan mentioned with a 10 year warenty for only $149.99 would be plenty of juice with four R9290's,..

 

When linking power supply's together or adding an "external box" to run pumps fans, etc,.. remember watts = volts X amps,.. and a standard 15 Amp wall outlet = 1800 Watts,.. you do not want to go over 75% of what the wall outlet is rated for so your looking at 1350 Watts for a standard 15 Amp outlet,.. provided it's a dedicated outlet with NO other outlets tied in or daisy-chained together running other appliances.

 

If you have a 20Amp dedicated outlet to plug your rig into,.. the Corsair AX1500i should easily run complete system. http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=378
