[SOLVED] 1000W PSU recommendation for sapphire nitro+ 7900XTX

[Native Text]

I can't decide what to buy since I can't find a clear winner, please suggest some good 80 plus gold fully modular 1000w PSUs.

What are your full system specs?

I've heard good things about this model and I've personally considered picking up one of these 850 watt units.

420W Total Board Power for NITRO+ AMD Radeon RX 7900 XTX Vapor-X

Is 1,000 watts needed, or would 850 suffice?

If build is on an Intel CPU platform, then perhaps higher wattage is indeed indicated.

If current rumor about future RTX 5090 being 1.7X performance of RTX 4090 then I wouldn't be surprised if wattage of the 5090 would exceed the 450 watts of the 4090.

I think 850w won't do for overclocking, my 7900xtx is yet to arrive in 4-5 days.
My system specs are - 7800x3d, 2x16gb cl32 6000mhz ram, asus b650e-f mobo
Not sure about this msi MPG series, I think Thermaltake Toughpower GF3 1000W is better.

Understood. Although I'm not personally a fan of Thermaltake products, except for their computer cases; they have some really nicely designed cases. with a budget of ₹16 000 INR ($192.74 USD), and a somewhat limited selection on the website you referenced, I'd personally opt for the Corsair RM1000e 1000 Watt. But, FYI the Corsair RMe series doesn't appear to have a 12/16 pin 12VHPWR PCIe connector. Also, to be clear, I've never personally used the RMe nor Thermaltake branded PSUs, but I just trust Corsair's high end PSUs more than any of Thermaltakes. I suppose that you could called a bias.

I found this on corsair's website -

The ATX 3.0 standard demands a high level of reliability and power efficiency. While many CORSAIR PSUs meet these requirements, RMe Series PSUs are formally certified for ATX 3.0 compliance.

PCIe 5.0 12VHPWR GPU cable included for use with modern graphics cards such as the NVIDIA® GeForce RTX™ 40 Series.

It actually has the 12/16 pin 12VHPWR PCIe connector.

Sort of. I believe they are including an adapter cable that plugs two-8 pin connectors into the PSU side, and one 12VHPWR PCIe connector into the GPU. That's a bad thing per se, but it means there isn't a native 12VHPWR socket on the PSU side.

Also, keep in mind that none of the AMD GPUs, including your 7900 XTX, use the 12VHPWR connector anyway. I only mentioned it, in case you one day decide to switch to a Nvidia GPU, and wanted native support for that new power connector.

one more reason to avoid then

I think thermaltake GF3 1000W supports atx 3.0 and is pcie 5.0 compliant natively.

Which PSU did you settle on purchasing?

Hey I went with the Thermaltake, posted a thread in Thermaltake's forums they replied with this - https://community.thermaltake.com/i...pin-pcie-connector-requirements-for-7900-xtx/

Not sure why they are not sharing the individual wattage carried by the cable.
