is 460 liquid cooling PSU okay for 1080 gtx aurora r7?

[junhoyoo95]

i bought aurora r7 from alienware dell. and i bought 460w PSU with liquid cooling instead of 850w. but my friends were worried about 460w being too low for my system

Intel(R) Core(TM) i7 8700 (6-Core/12-Thread, 12MB Cache, up to 4.6GHz with Intel(R) Turbo Boost Technology)
Windows 10 Home 64bit English
460W APFC PSU Liquid Cooled Chassis
NVIDIA(R) GeForce(R) GTX 1080 with 8GB GDDR5X
16GB Dual Channel DDR4 at 2666MHz (2X8GB)

If it’s good quality it will be fine. Your system will likely be drawing ~260w while gaming.
Are you able to find a model number for that power supply?

you'll be fine since the system is not overclocked.

if you had the 8700k and planned on overclocking, then i'd say it was not enough. but stock clocks on a 8700 won't pull anywhere near the power.

460W APFC PSU Liquid Cooled Chassis is the one and its also called Alienware™ 460 Watt Multi-GPU Approved Power Supply with High Performance Liquid Cooling

Imo it's a very bad idea. You choose high end components but when it's time to feed and protect those components you chose to cut the bleep out of that corner.

Also it would help if you knew what you were buying.

That's two components and Dell isn't helping at all. Chassis is the case. Liquid cooling would be describing the cooling of the CPU.

I see a no name PSU and a no name CPU cooler those are deal breakers for me. I then look to see which 1080 and once again I see a generic description. That suggests you will receive a reference/ vanilla/ founder's edition with a blower style cooler which typically runs hotter than those with triple or double fans.


Everything I am seeing tells me the answer to your question is a resounding no.

After more research, I've learnt there are five different 460w power supplies used in the Aurora R7, made by 3 OEMs - Delta, Acbel, and Huntkey. All of which have a max rating of 385w on the combined 12V rails, which is what your system will be mainly consuming from.
You should be fine, considering your systems average consumption during gaming is over 100w below that. Knowing they have Active PFC, they won't be complete garbage.

There have been complaints of the noise levels, though, especially at high load.

MERGED QUESTION
Question from junhoyoo95 : "460 liquid cooling PSU for 1060 gtx"

my PSU is 460 with liquid cooling from dell alienware. by the cooler master w calculation my system is about 360w consumption. so my question what happens if it goes up more than 460w and with ultra graphic setting gamings for fallout76 and new battlefield series might be risky to play with 460w PSU? if so, only choice now is to return the item and change to 850w PSU or get my self
a PSU and install it. what should i do?

no i dont know at this point. but its pretty decent they say. so what happens if you go over 460? and will my speaker and alienware 244 hz gaming monitor put more w into that? and is there a way i can check power usage?

Can you offer the number(s) below +12V? 460W is peak and not continuous. You're doing something I'd never do.

What sort of protections does it have? Short circuit? Over current? Under Current? Over temp.? Over Voltage? Over current?

My 80+ Gold rated PSU , I purchased specifically for an upgrade, has all those safety features which is also known as insurance. A lower quality PSU fails and it can send bad juice to everything connected to it. Go ahead and google. PSU's have destroyed entire PC's, just the board, only the GFX card etc.. Would I drive a car without insurance? Bleep the police, I am not going to invest thousands of dollars and not have full protection. I didn't invest $849 to put it in jeopardy. You may think you are getting lucky not having to upgrade and that may be true, you saved some money. In the long run? I wish you luck. I know the math works but that's not the whole pic. imo...

I believe the 460w is a continuos rating, though they’re right in that you should insure you have a PSU with a set of working protections to protect your parts in a fault.
And your PSU should have good performance to increase your components lifespans.
If you go over 460w, OCP or OPP may activate if they have correctly implemented the protections. Otherwise something would die.
You can check power usage using a power meter / kill-a-watt.

I recommend a PSU upgrade to a known quality unit, not necessarily higher wattage. Examples include the Bitfenix Whisper, Bitfenix Formular, Corsair RMX, EVGA G3, Seasonic Focus Plus.
