Corsair HX1000M 1000W 80 Plus Platinum Modular Power Supply
Delivery $11.90

I know power delivery makes cables hefty, but they were difficult to work with, even in a roomy case. However, I don't really trust anybody but Corsair for PSUs so options are slim!

It powers my 3090ti and r9 7900x pretty well. Always happy with corsair PSUs.

I bought this power supply to power a GPU miner. It is most efficient between 40% and 60% load (so 400W to 600W) of load. It came with a bag with a great range of cables. It is a standard ATX power supply and easy to mount although it is quite long (and the power cables plug into the end, so make sure it will fit your requirements if going into a case).I would be happy to buy this power supply again.

I got this when my old PSU couldn't support my new GPU. Works fine, no hassles. Almost forgot it was there which I believe is a good thing, does its job and leaves you alone.
Performance wise my pc doesn’t currently need the power from this psu but I got it for future proofing for my next gpu in mind. The fan doesn’t even operate with my system currently hence why it’s so quiet. Worth the price with the 10 year warranty. Fully praided black cables (fully modular). The 16 pin is a little thick but that’s to be expected. Had it for a month and have had zero problems with it. Keeps my pc nice and quiet. It’s a little long but I think that comes with all psu about this wattage
Rock solid rails, fully modular, silent on low load there is nothing not to love about this unit. Everything about it is 100% top notch even the packaging for the unit and the cables was high class. Well done Corsair!
The PSU can keep up with sudden increase in power draw without a problem, I tried loading my 5950x with a 4k x265 video encode while running Heaven benchmark on 3080 Strix (power supply set to multi rail) and no shutdowns occurred.PSU fan stays very quite even when on and chances are you won't hear it above the other fans in the computer.
I purchased a full PC from PCCaseGear recently and am stoked with every aspect of the hardware. Everything was super simple to setup and it has been running flawlessly since powering on.The only gripe that I have is the high price of the Lian Li vertical GPU adapter ($109) and an extra $9 for the CPU Mounting bracket. I personally feel that 40% of the case price for a bracket exhorbitant, and considering that I spent the best part of $6,000AUD, charging for the CPU mount was a bit on the nose.
Corsair are the industry leader in the quietist and most reliable PSU's around. The HX series is great and the 1000w is perfect for heavy duty applications, also this is one of there models that has the 10yr Warranty! Keep up the good work corsair.. Ill keep buying them!
