I'm getting conflicting estimated wattage at ASUS & pcpartspicker

Build

Asus Maximus VII Gene
i5 4430
Asus GeForce GTX 760 2GB DirectCU II
G.SKILL Trident X Series 16GB (2x8GB) DDR3 2400
2 x HDD 2TB SATA 6.0Gb/s
1 DRW

Any recommendations?

hi Noots, welcome to ROG.. anything 750wat + will do the job nicely, going above 1000wat is a waste of money,, If your thinking about doing water cooling go with a 1000wat, here's a couple of good psu's that will do the job.. If you want a nice clean build go for a fully modular psu, as you can keep your wiring down to only what you are going to be using..

Corsair CS750M Modular 80 Plus Gold Power Supply
Corsair HX850i 80 Plus Platinum 850W Power Supply

I agree unless your running say a pair of kingpins and doing a lot of overclocking something like a seasonic 860 would do very nicely..

You don't need a 750W PSU for a single GPU system.
Something like a Corsair HX650W or a Gold 650W Seasonic or EVGA PSU would be fine.

Intel i9 10850K@ 5.3GHz
ASUS ROG Strix Z490-E
Corsair H115i Pro XT
G.Skill TridentZ@ 3600MHz CL14 2x16GB
EVGA RTX 3090 Ti FWT3 Ultra
OS: WD Black SN850 1TB NVMe M.2
Storage: WD Blue SN550 2TB NVMe M.2
EVGA SuperNova 1200 P2
ASUS ROG Strix Helios GX601

The absolute max power draw on your system is going to be in the 350-370W range...figure in PSU aging and you should get something in the area of 450-500W PSU. Your system should idle fairly low and the efficiency of PSU's drops considerably at the low end, so you do not want to over spec it. (I'm making the assumption you aren't going to want to add additional graphics cards in the future)

A few suggestions on the system...de-spec the motherboard and RAM and up-spec the processor and graphics card. Also, a small SSD will perform much better than 2 HDD's in RAID, so I'd drop one of the HDD's and get a small SSD.

Hmm, we see this "minimum PSU" often, just bad advice IMO, some upgrades you don't plan for and Christmas is coming. Get a 750W of good quality. You will be able to sleep nights knowing your PSU is overkill. The PSU will not be in question when troubleshooting. You can upgrade when the time comes. You will lose little when the computer is at idle and the PSU efficiency drops - you are using little power so it does not matter. PSU's generally run best at 80% (assuming a quality PSU) so a 500W will be fine for your rig - provided you do not add anything.
Good advice on the SSD, nothing improves the feel of a computer more than a boot SSD with your current game on it.

Thank you everyone for your input and advice. This is my 7th build since 2003, and hopefully it will be uneventful like all of the other ones.

500W would not be a minimum for an application like this. The Falcon NW Tiki Z has an overclocked Titan Z and oc'd 4970K and works off of a 600W power supply. The Titan Z has over 200W more power consumption than a GTX 760, not even counting it being overclocked.

I agree you want the PSU to be operating around 80% to get the best efficiency, however you want that to be for a typical high load scenario, not the maximum theoretically possible power consumption; for reference, a 4790K and 780Ti will have a high load scenario under 250W.

Good luck with the build!

I haven't decided yet ... but I've been coveting a Lian lin for the past 7 years but always end up with a clunky Antec. Seriously looking at PC-V358A, but my pragmatic side is whispering Corsair Carbide CC-9011069.

Which PSU?
