A Seasonic power-supply calculator reportedly exposed preliminary GeForce RTX 50-series power and connector entries in October 2024. The figures suggested a 500 W RTX 5090 and 16-pin connections on most listed cards, but they were never final NVIDIA specifications. The RTX 5090 ultimately shipped with a 575 W Total Graphics Power rating, and the claim that every RTX 50-series card would use a 16-pin connector was too broad.
What the Seasonic leak actually showed
Contemporary reporting attributed the discovery to hardware leaker Olrak29, who found upcoming GPU entries in Seasonic’s online PSU wattage calculator. The entries reportedly included a model name, an estimated power figure and a connector field. PCGamesN’s report did not describe the data as a NVIDIA specification document, product brief, board-partner specification or regulatory filing.

That distinction matters. A PSU manufacturer may enter planning data, compatibility guidance or placeholders before a product launches. The listing could therefore be useful evidence of Seasonic’s expectations without being a definitive statement of a retail card’s maximum board power or connector design.

The reported preliminary figures
The table below reproduces the leak-era entries as reported. These are not final specifications, and “TDP” in the contemporary coverage should not be read as measured gaming draw, wall power or a guaranteed peak value.
#1 Best Overall
- NVIDIA Ada Lovelace Architecture
- GPU Memory: 32GB GDDR6 ECC
- NVIDIA Quadro Sync II compatibility
- RT Cores: 100 Gen 3
- Tensor Cores: 400 Gen 4
| Reported model | Preliminary power figure | Connector shown in the listing |
|---|---|---|
| RTX 5090 | 500 W reported leak | 1 × 16-pin 12VHPWR |
| RTX 5080 | 350 W reported leak | 1 × 16-pin 12VHPWR |
| RTX 5070 | 220 W reported leak | 1 × 16-pin 12VHPWR |
| RTX 5060 | 170 W reported leak | 1 × 16-pin 12VHPWR |
| RTX 5050 | 100 W reported leak | No additional connector listed |
Relative to the preceding generation, the reported increases were 50 W over the RTX 4090, 30 W over the RTX 4080, 20 W over the RTX 4070 and 55 W over the RTX 4060. Those comparisons made the leak significant for upgrade planning, particularly in systems built around modest power supplies.
“All get a 16-pin connector” was not literally true
The headline claim was already misleading on the leak’s own terms: the RTX 5050 entry showed no auxiliary connector. A calculator field also cannot guarantee that every add-in-board manufacturer will use the same connector as a reference design. Founders Edition and partner cards can have different power targets and cabling.
Later reporting questioned whether the RTX 5060 Ti and RTX 5060 would require 12VHPWR at all, further weakening the “all models” interpretation. PCGamesN’s later connector report describes lower-power cards using other arrangements in some designs.

- Adapter: A bundled converter that combines multiple conventional PCIe 8-pin cables.
How credible was the leak?
It was plausible but unconfirmed. The information reportedly came from a real PSU manufacturer’s calculator and appeared to cover a coherent product stack, rather than an anonymous spreadsheet. Several entries were also directionally consistent with the higher power requirements eventually seen at the top of the generation.
It was not final because the listing did not identify whether its values represented reference-board power, typical board power, maximum board power or a PSU-selection recommendation. Pre-launch entries can change, and the eventual desktop lineup included the RTX 5070 Ti and RTX 5060 Ti, which were absent from the five-model listing. NVIDIA’s official comparison page now lists the broader range of desktop products: RTX 50-series comparison.

What NVIDIA ultimately confirmed
NVIDIA announced the desktop and laptop RTX 50-series on January 6, 2025. Its announced U.S. starting prices were $1,999 for the RTX 5090, $999 for the RTX 5080, $749 for the RTX 5070 Ti and $549 for the RTX 5070; the first two became available on January 30, 2025. These were launch prices, not guaranteed partner-card or street prices. NVIDIA’s announcement and availability notice provide the dated details.
The RTX 5090 Founders Edition is higher than the leak suggested
NVIDIA rates the RTX 5090 Founders Edition at 575 W Total Graphics Power, not the leaked 500 W. NVIDIA recommends a 1,000 W system PSU. The card can use four PCIe 8-pin cables through the included adapter or one 600 W-rated PCIe Gen 5 cable. Its listed dimensions are 304 mm long by 137 mm wide; NVIDIA describes the Founders Edition as a two-slot card with a 90°C maximum GPU temperature. See the official RTX 5090 specifications and quick-start guide.

What TDP or TGP means for PSU planning
A GPU’s TDP, TBP or TGP is a graphics-card power metric, not total system consumption. Short transients can exceed the nominal rating, while the CPU, storage, fans, pumps and overclocking add to the system load. NVIDIA’s recommended PSU figure is a system-level recommendation, not a statement that the GPU continuously consumes that amount.
For that reason, use the exact card manufacturer’s requirement rather than applying the leaked number to every version of a GPU. The same product name can cover a reference card and substantially different partner boards.

Does an RTX 50-series upgrade require a new PSU?
Not automatically. A 16-pin socket does not, by itself, make an existing power supply obsolete. NVIDIA explicitly documents adapter-based support for the RTX 5090 Founders Edition, so a suitable older PSU can work when it has adequate capacity, enough separate PCIe cables and a safe installation.

- Its wattage meets the exact card manufacturer’s recommendation with sensible headroom for the CPU and the rest of the system.
- It is a reputable, healthy unit rather than an old, damaged or low-quality design.
- It provides the number of independent PCIe cables required by the included adapter.
- The case supports the card and leaves room for the connector and cable bend.
A replacement is more advisable when
- The card is an RTX 5090-class model and the current supply is near its limit.
- The PSU lacks enough separate PCIe cables for the adapter or has no suitable native Gen 5 output.
- The supply has caused shutdowns, overheating or connector damage.
- The exact partner card specifies a higher wattage than the Founders Edition guidance.
- The PSU is old, heavily degraded or uses a design with inadequate protections.
Check the exact installation before powering on
- Identify the precise GPU model and read its manufacturer’s PSU and connector requirements.
- Confirm the CPU, drives, fans, pumps and any overclocking do not consume the headroom you are relying on.
- Use separate PCIe cables for separate adapter plugs when the card or PSU instructions require it; never substitute a CPU EPS 8-pin plug.
- Use only modular cables approved for that exact PSU model. Modular cables are not universally interchangeable between brands or even product families.
- Seat the 16-pin connector fully and route it without a sharp bend or side-panel pressure immediately beside the plug.
- Check radiator, drive-cage, side-panel and overall card-length clearance before closing the case.
What about reports of melting 16-pin connectors?
The 16-pin connector became controversial after reports of overheated or melted RTX 4090 connectors. The relevant risks include incomplete insertion, cable strain, tight bends close to the plug and poor contact. That does not mean every 16-pin installation will fail.
Follow the GPU and PSU manufacturer’s instructions, push the connector fully home and keep the cable’s bend radius away from the plug. A native Gen 5 cable can simplify routing by avoiding a multi-plug adapter, but it is not an immunity guarantee. The Founders Edition RTX 5090 and RTX 5080 were reported with angled connector arrangements intended to better suit common cable routing, while lower-power partner cards may use different layouts.
What the leak got right—and what it missed
Directionally right
- High-end RTX 50-series cards would demand substantial power.
- The RTX 5090 would occupy a higher power class than the RTX 4090.
- Modern 16-pin PCIe cabling would matter for high-end configurations.
- PSU capacity, cabling and physical clearance would be part of the upgrade decision.
Wrong, incomplete or misleading
- The RTX 5090’s final official 575 W TGP exceeded the reported 500 W.
- The “every card gets a 16-pin” wording conflicted with the reported RTX 5050 entry, which listed no auxiliary connector.
- The leak omitted the eventual RTX 5070 Ti and RTX 5060 Ti.
- It did not establish final partner-card specifications.
- It blurred GPU power terminology, connector type and system-PSU recommendations.
- It encouraged the idea that every owner needed a new PSU, which does not follow from the connector alone.
Bottom line for an upgrade
The October 2024 Seasonic listing was a useful warning that RTX 50-series power requirements could rise, but it was not a final specification sheet. Treat every leaked wattage and connector entry as preliminary. For a purchase today, check the exact retail card, its stated PSU requirement, its cable method and your case clearance. A quality existing PSU may be sufficient with the correct adapter and independent PCIe cables; an undersized, damaged or poorly cabled unit should be replaced.
