Quandrel Graphics Store · Centum, Busan
About our Busan GPU shop
We sell graphics cards at 15, Centum 1-ro, and we advise on them. Those are two different jobs, and the second one is the reason people walk in.
What we can usually do at the counter
Pickup · advisory · ordersThree things come up most often when someone stands at the counter with a monitor in mind. The strip below reads like a departure board: the left column names the task, the mono columns carry the practical detail, and the day digits mark how reliably we can handle it on a given weekday.
- Fit check with your monitor and case same day walk-in – 12345
- Stock question on a card we carry minutes same day – 123456
- Order a higher RTX 50 tier or rare Radeon 1–2 days on arrival varies 123456×
- Used card inspection before you pay by arrangement call first – 12345
Where we are, and why that matters
We sit in the Centum area of Haeundae-gu, a short walk from the Haeundae electronics cluster and reachable from most of Busan by metro or a single bus ride. Being local changes what you can do before you spend anything: see a card out of its box, measure its length against your case, ask about the connector count with the card in hand, and carry your order home the same afternoon instead of tracking a courier.
If you are travelling in from outside the district, call +82-51-740-2211 before you set out. We will confirm what is actually on the shelf that day, so the trip is worth the fare. We are open Monday to Friday, 09:00–18:00.

What we stock, and what we order
The shelf holds current midrange and entry cards. Anything higher up the stack, or any model that is unusual for this market, we order on request — and we tell you plainly whether it is here, arriving, or genuinely hard to source this month. Korean distributor stock moves, so a card that was easy in spring can be slow by autumn.
On the shelf
GeForce RTX 5070
The current midrange anchor for most first and second builds. We keep a couple of cooler variants so you can compare length and thickness before deciding.
Higher 50-series tiers: order
On the shelf
Radeon RX 9070
A straight alternative when someone wants raster performance first and is willing to give up a little ray-tracing headroom. Ask and we will show both side by side.
Less common Radeon: order
On the shelf
Radeon RX 7800 XT
Still one of the sensible answers for a 1440p build on a fixed budget. It shows up in value conversations more often than its age suggests.
Restock timing varies
On the shelf
Intel Arc B580
An entry card worth knowing about if your budget is tight and your monitor tops out at 1080p or a modest 1440p. We will say what you give up in return.
Entry-tier alternative to used
How we prepare buying advice
Advice here starts from three facts about the machine you already own, not from what is most expensive in the case. We ask for your monitor's resolution and refresh rate, your power supply's wattage and connector count, and the clearance inside your case. Those three answers usually narrow the shelf to one or two sensible cards.
When two cards are genuinely close, we say so and explain the trade-off in plain terms — usually DLSS and ray tracing against price, or VRAM against a heavier cooler. And when your current card is still enough for the resolution you play at, we will tell you that instead of selling you a box. That answer costs us a sale and earns the next visit.
What we ask you to bring
- ResolutionWhat your monitor runs, and whether you plan to change it soon.
- PowerWattage and how many connectors the supply offers.
- ClearanceLength, thickness and slot width free inside the case.
- BudgetA range you are comfortable with, so we stay inside it.
What we do not do
We do not call a card future-proof, and we do not promise a price will stay where it is. GPU prices in Korea respond to memory costs, import conditions and whatever stock distributors happen to be holding. Korean coverage in 2026 linked RTX 50 price pressure to rising GDDR7 memory costs, with Samsung and SK Hynix among the producers behind that supply. That is exactly why we quote today's shelf rather than a figure from launch week.
What that means for you in practice: a quote we give on Monday may not survive to the following week, and the honest answer to "will it drop?" is often that nobody knows. We would rather tell you that than invent a number.
Used and previous-generation cards
Previous-generation cards still do real work for real buyers here. The Radeon RX 7800 XT keeps appearing in 1440p value discussions, and the GeForce RTX 30 series remains the fallback people compare against whenever new cards get more expensive.
When we handle a used card, we inspect it and describe its condition before you commit — cooler noise, fan bearings, whether it has been opened. We will also tell you when a used card is the better value for your case, and just as plainly when it is not worth the saving.
A shop for first-time builders too
A good share of the people who come through the door are building their first PC. That is fine here, and there is no question too basic to ask at our counter. We explain VRAM, cooler sizes, and which cable goes where in ordinary language, then let you make the call without hovering over your shoulder.
If you are weighing an entry card like the Arc B580 against a used option at a similar price, we will walk through what each one gives up — driver maturity, warranty, resale, and how much headroom is left for the next upgrade. No pressure, and no jargon you did not ask for.
The people behind the counter
We are a small Busan team that works with graphics hardware every day. Our edge is not a warehouse holding every SKU in the market — it is that we follow what actually ships to Korea, what gets delayed, and how memory pricing drags card prices around from month to month. When a model is not one we would buy ourselves at your budget, we say so and point you at something that is.
If you want the longer reasoning behind a recommendation, ask at the counter or send it in writing. We would rather spend ten minutes explaining a connector than have you come back with a card that does not fit.
See the GPU catalogHow to reach us
Visit the shop on Centum 1-ro, call +82-51-740-2211 during opening hours, or send a stock or compatibility question through the contact page. Tell us your monitor, power supply and case clearance in the first message and we can usually answer in one reply rather than five.
For pickup, we confirm stock before you travel so the trip is worth it. If a card has to be ordered, we give you the realistic window rather than the optimistic one.

Questions people ask before visiting
-
Are you a physical store or online only?
Physical, in Haeundae-gu, Busan. You can visit, see the cards, and pay in person. Online questions are welcome too, but the shelf itself is right here on Centum 1-ro.
-
Can you order a card you do not stock?
Often yes, depending on distributor stock. Send us the exact model and we will tell you what is possible and roughly how long it takes — including when the answer is that it is not worth waiting for.
-
Do I need an appointment to ask about a card?
No. Walk in during opening hours and ask. If you want to see a specific card pulled out for a longer look, calling ahead helps us have it ready when you arrive.
-
What should I bring if I want advice?
Your monitor's resolution and refresh rate, your power supply wattage and connector count, and how much room your case leaves for a card. A photo of the inside of the case often settles the question faster than a description.
-
Do you buy or trade in used cards?
We handle used cards case by case and inspect before anything changes hands. Bring the card in and we will tell you what condition it is in and whether it is worth selling at all.
Tell us what you are building
Send your monitor, power supply and case clearance, and we will tell you which cards on our shelf actually fit the build — then you can decide whether the trip to Centum is worth it.
