Advise on power supply (and maybe more) required

Thinking of going from a mid tower to a micro atx form factor
Items on wish list

    motherboard   ASRock FATAL1TY X99M KILLER/3.1 
  cpu   i7-6900k

gpu ASUS GeForce GTX 1070 TURBO-GTX1070-8G
ssd x 2 Samsung 850 EVO 500GB
ssd boot Samsung 950 Pro M.2 256GB
ssd storage Samsung 850 EVO 2TB 2.5" --maybe
ram CMK32GX4M4A2666C15
power supply ???
cpu cooler H100i
odd 1 bdr-209dbk
odd2 wh16ns40

Cases I am thinking about are
MicroATX Mid Tower Air 240 High Airflow
SPEC M2

Both are corsair

Power supply RM650i also corsair

Is this power supply large enough
Any opinions / advice on the components are welcome

The TDP of the CPU is 140W
The TDP of the graphics card is 150W
If you give 5W for each of the SSDs and you have four of them (20W)
Then allow for motherboard, RAM, and cooling power requirements.
Total power @ load will probably be in the region of 340W.

A 500W PSU would be enough, but 650W would provide more efficiency and give some headroom. So 650W would be more than enough.

Thanks

My rule of thumb is to count the total current @ full load then x2. Purchase a quality PS. Read reviews on various makes. Also look into the benefit of single vs dual rail 12v supply. Don’t scrimp, buy a decent PS. If you try to save a few $$ you run the risk of damaging components if the supply goes FOOBAR. Been running a 1200w supply for my last three builds since 2011.

The rm750i is only $10 more than the 650 watt version and you can change it between a single and dual rail via the corsair link

#6

I would go for a minimum of 650-700Watt PSU, I will assume that you will probably be
overclocking your CPU, if not also the GPU, so the extra watts will come in handy
and then the power goes up and away from what the manufacturer says.

Also anything from a reputable manufacturer, with a good warranty and you should be able to use that PSU with our next PC.

#7

The only problem is that the spec M2 case will only allow up to a 650 watt power supply
If I go with win10 I wont have to worry about win7’s usb bug, however

#8

Just to get things into perspective.
I have an 6700K TDP 95W overclocked to 4.6GHz.
An Nvidia GTX1060 TDP 120W
7x SSDs.
I have a 550W PSU, and at full load its using 263W measured by a power meter from the mains socket.

A modern (Titanium certified) PSU are most efficient when providing 50% of their rated power output.

Nvidia themselves recommend a 500W PSU for a typical system using a GTX1070.

#9

Thanks for the perspective
7 SSDs?

#10

Opps
I’m bad. It’s actually 9x SSDs. :slight_smile:
8X SATA
1X M.2

#11

And I thought I was overdoing it on SSDs. :o
The more the merrier :clap:

#12

You can never have enough installed :bigsmile:

Just joking.
