What psu should i use ??

BlueTear Robert · May 17, 2015

Hello. For some time i wanted to make my own computer from parts and not to buy one that is already made. And i encountered a problem at choosing the Psu for it.
The spec. for the PC is:

-ThermalTakeV71 Full Tower Computer Case
-Corsair Psu CS Series™ Modular CS850M — 850 Watt 80 PLUS® GoldCertified PSU
- Asus MAXIMUS VII FORMULA Motherboard , Socket 1150
- VGA ROG MARS760-4GD5 x2 ,(4GB DDR5, 512-bit)
- Cpu Intel-core, I7-4790k, Socket 1150, 4.4ghz, 8 mb cache
- Ram Corsair Vengeance Pro,16gb, Ddr3-2666mhz, Dual-Channel-Kit (2x8gb)
- Optical Drive Blu-Ray Asus Bw-16d1ht Bulk Black
- Ssd Samsung 850 EVO 250GB (MZ-75E250B/EU)
-Hdd Seagate Barracuda 2tb, 7200rpm, 64mb, Sata3,
-Noctua NH-D15lga 1150 (for the cpu)

Now can some one tell me if the psu that i choose for my pc is a good one or not. Should i put a bigger one like 1000 Watt or so or one from another serie like the RM, HXi, or AX.

What is your budget and goals for the system?
There are several things I would change as well as the PSU.

BlueTear Robert · May 17, 2015

Well i want to make a gaming PC. And the budget lets say 2.500 euro.

Corsair RM Series RM1000 1000W 14cm Fan 80+ Gold this one is only 40 dollars more but is enough not only to support your build but gives you a room for upgrades

Gam3r01 · May 17, 2015

RM uses cheap capacitors, cheap caps=cheap unit.
I would drop the motherboard down the the Z97-A.
Consider a 4690k and put the extra to a graphics card.
You really only need 8GB of 1600MHz CAS9 ram.
Drop the mars, as its a gimmick card, get something like a 970/980 instead.
For the PSU, look into an ~600w+ unit from Antec, Seasonic, XFX, or EVGA (B2, G2, GS), 750w+ if you plan to xfire/SLI later.

Oh and i like your build verry much its nice to have the money to build such monsters be sure to give it as good cooling system

BlueTear Robert · May 17, 2015

About upgrades i was just thinking about because in the end i will want to have 35gb of Ram and maybe a 2nd VGA. I plan to make a sli after some time

Bengal Tiger · May 17, 2015

you type x2 there allready

Gam3r01 · May 17, 2015

Thats because its the MARS 760. Its two 760 chips on a single PCB.
Its a waste of power, money, and heat.

BlueTear Robert · May 17, 2015

I typed x2 because i wanted to know what psu is good for them. At the start i will buy only 1, and after some time i will make a sli.

Bengal Tiger · May 17, 2015

ok let me give you something else as an option or 2

So are u saying that in the end 1 gtx 980 is better that the mars 760? right?

Corsair HXi Series HX850i 850W 14cm Fan 80+ Platinum Modular

Gigabyte GeForce GTX980 4GB Gaming

i was just looking at the hxi psu.

Gam3r01 · May 17, 2015

A single 980 will outperform a MARS by about 20% in games that support SLI, by about 50% in games that dont.
For the PSU, US link for reference, you can find it in your specific country http://www.newegg.com/Product/Product.aspx?Item=9SIA24G28N0652
EVGA SuperNova G2. Made by superflower, the best of the best. Quality cant be beat.

No comment about evga psu. I think i will take one with 1000Watt to be sure i have enought power. And regarding the VGA i think i will switch the mars with a 980, just dont know if it will be from gigabyte or asus

Gam3r01 · May 17, 2015

Gigabyte G1 Gaming is the best, followed by the MSI Gaming.
You will never need a KW of power in your system, as a single 980 only draws 190w.

Bengal Tiger · May 17, 2015

go for gigabyte

BlueTear Robert · May 17, 2015

nice thx for the advice regarding the psu. i will take the evga 850. and also the VGA il go for the g1
