ASUS GeForce RTX 5090 ROG Astral LC 32GB GDDR7
The integrated AIO liquid cooler on the 32GB GDDR7 Blackwell chip and a 2610MHz boost clock keep this factory-overclocked RTX 5090 running cool under its 575W load. It uniquely pairs a compact 279mm 3-slot form factor with a closed-loop cooler, fitting high-end power into more cases than typical air-cooled flagships. This card is best for 4K gamers and AI developers needing top-tier 94.8/100 LLM performance in a refurbished, space-efficient package.
Overzicht
The 30-Second Version
The fastest GPU we've ever tested, cooled by a 360mm AIO that actually works. Absurdly expensive, but if you want the best, this is it.
Pros & Cons
Pluspunten
- Fastest gaming GPU we've ever benchmarked 100th
- 360mm AIO keeps it at 55°C under load 99th
- 32GB GDDR7 is future-proof for 8K and AI work 98th
- Dual HDMI 2.1b plus triple DP 2.1 is a connectivity dream 98th
Minpunten
- Price is absolutely bonkers, USD 3,900 to USD 8,300
- Card is wider than its own AIO cooler, case fit is a nightmare
- 575W TDP means you need a serious PSU
- Efficiency is rough, 28th percentile

Performance
The numbers are stupid good. 32GB of GDDR7 on a 512-bit bus, 21,760 CUDA cores, and a 2,610MHz boost clock push this thing to a PassMark G3D score of 38,845, which lands it in the top tier of our entire database. What surprised us most wasn't the raw speed though. It's the thermals. Owners report 55°C max under full load, and the card barely breaks a sweat at 4K. That's liquid cooling done right.

vs Competition
Against the Gigabyte AERO RTX 5080 or the ZOTAC APOCALYPSE RTX 5080, the Astral LC wins on raw speed but loses badly on value. The 5080 cards deliver maybe 70-75% of the performance for less than half the price. The MSI Ventus RTX 5070 Ti is even more sensible if you're gaming at 1440p. But none of them touch the 5090's 32GB of VRAM or its 4K and 8K chops. If you want the best, this is it. If you want smart money, get a 5080.

Prijs
Value & Pricing
Let's be real: this is not a value purchase. The price spread is wild, from USD 3,900 to USD 8,300 across US listings, and CAD 5,700 to CAD 18,033 in Canada. If you're buying, hunt for the lowest listing and don't pay a cent over USD 3,900. But even at that price, you're paying a massive premium over a 5080 for maybe 20-30% more performance. This is a want, not a need.

Overview
The ASUS ROG Astral LC RTX 5090 is the fastest gaming GPU we've ever tested, full stop. It pairs NVIDIA's flagship Blackwell chip with a 360mm AIO cooler that keeps the whole thing absurdly cool and quiet. The one thing to know: this is a halo product for people who want the absolute best and don't care what it costs.
Common Questions
Q: Will this fit in my case?
Probably not without some work. The card is 288mm long and wider than its own AIO cooler. Owners report it doesn't fit in a Lian Li O11-D without a vertical GPU mount. Measure your case carefully and budget for a vertical mount kit.
Q: What power supply do I need?
ASUS recommends a 1000W PSU minimum. The card pulls 575W TDP on its own, and you'll want headroom for the rest of your system. Don't cheap out here, a quality 1000W unit is the floor.
Q: Is the liquid cooling worth it?
Yes, if you care about noise and thermals. Owners report 55°C max under full load, which is exceptional for a 575W card. The 360mm radiator does real work here, not just marketing fluff.
Who Should Skip This
If you're gaming at 1440p or even 4K on a 60Hz monitor, this card is overkill. You're paying a massive premium for performance you won't see. Go grab an RTX 5080 like the Gigabyte AERO or ZOTAC APOCALYPSE and spend the savings on a better monitor or a pile of games.
Verdict
The ASUS ROG Astral LC RTX 5090 is a monster GPU with cooling that actually justifies the liquid setup. It's the fastest card we've tested, runs cool and quiet, and has VRAM for days. But the price is offensive, the case fit is a pain, and the efficiency is mediocre. Buy it if you want the absolute best and money is no object. Everyone else should grab a 5080 and call it a day.
