PSU Recommendation (struggle)

[josepchappa]

Hi I am planning to build a new Computer. I have pretty much everything set up. The only thing missing is the PSU.

Here the specs:

 

Case:                Corsair Obsidian Series 750D (3x 140mm Fans)

Motherboard:    MSI /97 Gaming 5 Intel Z97 So.1150 Dual Channel DDR3 ATX Retail

Processor:        Intel i7 4790k 4x 4.00GHz So.1150 BOX

Graphics:          MSI GeForce GTX 780 Ti Gaming 3G Active PCIe 3.0 x16 (Retail)

RAM:                 8GB Crucial Ballistix Sport DDR3-1600 DIMM CL9 Dual Kit (2x 4GB)

Harddrive:         1000GB Seagate Desktop HDD ST100DM003 64MB 3.5" (9.8cm) SATA 6Gb/s

SSD:                 256GB Crucial MX100 2.5" SATA 6Gb/s

CD Drive:          Samsung SH-224DB/BEBE DVD-RW SATA 1.5Gb/s

Others:              Corsair Hydro Series H110 AIO Watercooling for the CPU

                          2x be Quiet! Silent Wings 2 140mm

 

 

I also want to ad another GTX 780Ti in the future and want to also Overclock (CPU, GPU, RAM). RAM is optional.

 

So the question: What PSU do I need that can hold my build now AND in the future?

 

Currently I have this in mind:

550 Watt be Quiet! Dark Power Pro 10 Modular 80+ Gold

I'd say 850W would be good for SLI.

Go for Corsair/Seasonic/Evga, >750w, Gold rated or above

Corsair RM850!

Ok. What if I would buy another PSU together with the second GTX780ti? What PSU is good then?(just 1 Graphicscard)

Well buying an 850W now would save you from having to sell the 550W and buy another PSU (the 850W) later, and fiddle around with your cable management a whole lot.

 

750W might cut it, but I would suggest 850W for Overclocking especially.

 

RM Series is unimpressive.

Don't consider just the brand, consider the units quality as well.

 

EVGA Supernova G2. Cheap for the Wattage, and very nice quality and performance.

CM V850. Excellent also.

AX850, 860 and 860i. Probably more expensive, but still good.

 

I'd recommend looking for these in that order.

EVGA Supernova G2 850W all the way, if you are able to purchase one.

I think I'll just buy a 550W first. I don't mind The extra work I'll have to put into cable management.

So what good 550W psu can you recommend?

If you are in the USA - http://www.newegg.com/Product/Product.aspx?Item=N82E16817151136

 

UK - Same PSU as above 

 

If you don't mind non modular then look at the NZXT Hale Power 90+ 550W if you can get one.
