Is the RTX 5090 worth it over the RTX 4090?

For 4K gaming at high refresh rates and for AI or rendering work that uses the 32 GB of memory, yes. If you play at 1440p or upgrade every generation, the gain is smaller than the price suggests.

What power supply does this card need?

Plan for a quality 1000W or higher ATX 3.1 PSU with a native 12V-2x6 connector. The card draws well over 500W under load, and transient spikes are high.

Will it fit in my case?

The Astral is a very long, thick card, so check your case's GPU clearance and your motherboard's slot spacing before buying. A full-tower case is the safe choice.

Expect the card, a support bracket, a 12V-2x6 adapter cable and documentation. Check the listing for exact bundle contents, since some sellers ship the card alone.

Is the current price a good one?

At $7,349.00 at eBay as of November 4, 2026, it is far above the card's launch price. Compare against other RTX 5090 models before paying this premium.

Does it support DLSS 4 and frame generation?

Yes. The RTX 5090 supports DLSS 4 with multi-frame generation in supported games, which helps most at 4K with ray tracing on.

Our take on the ASUS ROG Astral GeForce RTX 5090 OC

The ASUS ROG Astral GeForce RTX 5090 OC is a flagship graphics card built on Nvidia's RTX 5090 GPU, with 32 GB of GDDR7 memory and a large quad-fan cooler. It targets 4K and high-refresh gaming, local AI work and heavy creative rendering. The card is very large and power-hungry, so case clearance and a strong PSU matter. Its best new price is $7,349.00 at eBay as of November 4, 2026, well above the card's launch pricing.
