EVGA supernova 1300w or 1600w

post #1 of 6
Thread Starter 
I'll try to keep this brief but i need to upgrade my power supply now. My current evga supernova 1000w has served me well the past few months but i am now crossing the point where it absolutely will not be enough. I don't mind pushing these power supplies to their limits, i know they can handle it. Because of this i'm not 100% sure if i just go all out at this point on the 1600w or save a lot of money with the 1300w ps. Another plus for the 1300w is that its about an inch shorter in length which i like because it'll stay completely hidden under the mobo tray of my cl s8.

Current setup consists of
6700k @ 4.7ghz 1.368vc
4x4gb corsair lpx vengeance 3000mhz 15cas ddr4 ram
gigabyte z170 gaming 7 mobo
2x gigabyte g1 gaming 980ti's with custom bios @1540mhz core and 1.275v
2x AC d5 pumps
aquaero
12x corsair sp120 performance edition pwm fans
2x corsair af120 quiet edition fans
1x corsair af140 quiet edition fan
farbwerk w/4 led strips
samsung sm951 512gb m.2 ssd
2x samsung 850 evo 500gb in raid 0
ocz vertex 4 256gb ssd
crucial 128gb m4 ssd

The 1000w supply has held up fine with this

New setup
6700k delidded, 4.8-4.9ghz, basically whatever ~1.45vc gets me
4x8gb g.skil trident z 3200mhz cas 14 ddr4 ram, will be oc'd beyond stock settings and voltage
gigabyte z170 soc force mobo
3x gigabyte g1 gaming 980ti's with custom bios 1.275v
2x AC d5 pumps
aquaero
20x corsair sp120 performance edition pwm fans
2x corsair af120 quiet editions fans
1x corsair af140 quiet edition fan
farbwerk w/4 led strips
2x samsung 951 512gb m.2 ssd in raid 0
2x samsung 850 evo 500gb in raid 0
ocz vertex 4 256gb ssd
crucial 128gb m4 ssd

So do i spend them money on a 1600w supply and be done with it forever or can i get away with 1300w? Or do i go with a different supply from a different brand? Rig is used for gaming and some benching. Thinking about getting into folding as well. I've been building systems for over 10 years now but never anything this powerful.

I don't see myself ever going beyond tri sli unless the diminishing returns from sli become significantly less in the future.

You are already aware that the G2 does not have any hybrid fan mode right?
If you want hybrid fan mode you need to look at the P2 and T2 instead.

if i get the 1600w i'll go with the p2 since its only $30 more on amazon right now. Tbh, i don't care about hybrid mode. My pumps at idle are louder than the fan on my 1000w g2 at idle. The real question is if 1300w is enough or do i spend the extra money and never worry about having enough power again.

I would get a kill a watt and see what your power draws are.
Just remember that the numbers from the kill a watt is not what the system is using as you have to take the efficiency of the PSU off the numbers.

i got my kill a watt in from amazon today and did some testing. The most stressful programs i use on my computer currently are ffxiv benchmark, witcher 3 and rise of the tomb raider run on max settings. With both of these games and the benchmark i saw an average of 900w at the wall with a peak of 990w. I made sure all my fans and both pumps were run at max speed during testing.

I also did these same tests with sli disabled to somewhat simulate what another card may add in power requirements by taking the difference. I realize the second card still being installed will add to power consumption so its a very rough estimate. Average was around 530w with a peak of 582w.

Now evga rates my 1000w g2 ps at 90% efficiency so i assume its just as simple as multiplying the peak numbers by .9 to get the actual power consumption of the system. Someone please correct me if i am wrong.

990*.9=891w
582*.9=523.8w
891-523.8=367.2w
891+367.2=1258.2w

So if i did all my math right a 1300w ps with three cards and another 17w worth of case fans is technically enough but is cutting it very close. If i run something more stressful i'm out of ps.
