Is my HX1000 enough for my RVIE w SLI 1080Ti


Recommended Posts

I will be building up my system this week:



Rampage VI Extreme

SLI 1080Ti

NVME 960 evo

32GB Dom Plat 2800 mem


I will not be overclocking, just letting the board ramp as it will automatically (for now).


Will my HX1000 PSU be enough for this? I can't find an AX1200i or 1500i or 1600i in stock anywhere to buy....nowhere online or at any local microcenter.


Once I find an AX1600i in stock I'll replace this thing, but who knows how long that will take? I just don't want to damage anything until then, it could be months.

If it helps, a 1080 ti card draws about 270-280 watts at factory clocks. This figure includes power delivered via the PCIe slot. Full-tilt-boogie overclocks bring the figure close to 330 watts.

A 1kw PS should be fine, even with some OC action, waka waka

I'm going to say yes but only just. Here's my former build who's motherboard died back in Oct and I'm currently waiting on 1200w availability so I can put together my Coffee lake build.


i7 4790k@4.6

16GB Corsair Dominator Platinum DDR3@2133

Asus Maximus VII Formula

2x EVGA 1080ti FTW3s

2x Samsung 840 Evo 500gb

2x WD Black 4tb

EVGA G3 1000w

Corsair H100i

Corsair Air 540 w/ 6 Corsair HD Fans

EVGA G3 1000w

Various USB Devices(KB/Mouse/Headset/Etc)


On a few newer, hardware intensive games like AC:Origins, Witcher 3, etc I'd see my UPS report 870-900w load. I could synthetic bench it to a hair over 900w. For me I prefer to have a bit more than 100w headroom which is why I'm waiting for Corsair or EVGA to restock retailers with 1200w models.
