Hey fellow PC builders and budget-conscious upgraders! John Doe here, and if there's one thing I've spent more time doing than actually playing games on my rig, it's haggling for components at Techno Mart or sifting through listings on 당근마켓 (Karrot). The used PC parts market is a goldmine for value, but in 2026, it's also a minefield if you don't know your prices.
Today, we're diving deep into the real-world street prices for SSDs, HDDs, CPUs, and RAM. Forget what online retailers say about brand-new components; we're talking about the sweet spot of savings you can achieve by buying or selling used. I'll share my personal experiences from recent deals – like snagging a pristine Samsung 980 Pro 1TB for a steal last month, or offloading my old Intel i7-10700K faster than I thought possible.
Let’s get those spreadsheets ready and make sure you're getting the best bang for your buck!
TL;DR: The Quick Scan for the Busy Builder
- SSDs (NVMe/SATA): NVMe Gen4 still dominates the used market, with Gen5 slowly entering. Price drops for 1TB/2TB are significant.
- CPUs: Intel 12th/13th Gen and AMD Ryzen 5000/7000 series offer incredible value. Check motherboard compatibility first!
- RAM: DDR4 prices are stable/declining for common speeds (3200MHz), while DDR5 (6000MHz+) holds value due to newer platforms.
- HDDs: Primarily for bulk storage, prices are very stable per TB, but consider age/health.
- The Golden Rule: Always verify component health (CrystalDiskInfo for drives, CPU-Z for RAM/CPU) and meet in person for high-value items.
1. Solid-State Drives (SSDs): The Speed Demons of Storage
The SSD market has been a rollercoaster, but in early 2026, prices for used drives offer incredible value, especially for NVMe Gen4. Gen5 is still bleeding-edge, so used options are rare and expensive.
A. NVMe SSDs (PCIe Gen4 Focus)
My Take: Last December, I grabbed a Samsung 980 Pro 1TB for ₩120,000 on 당근마켓. The seller even showed me the CrystalDiskInfo screenshot with 98% health. Compared to a new one at ₩180,000, that's a sweet 33% saving! For Gen4, the sweet spot for used drives is definitely 1TB to 2TB.
Key Brands: Samsung (980 Pro, 990 Pro), SK Hynix (P41 Platinum), Micron (Crucial P5 Plus), Western Digital (SN850X).
| Capacity | Used Price Range (KRW) | New Price (Online) (KRW) | % Saving | Notes |
| 500GB | ₩50,000 - ₩70,000 | ₩90,000 - ₩110,000 | 30-45% | Good for OS drive, but 1TB is better value. |
| 1TB | ₩100,000 - ₩140,000 | ₩180,000 - ₩220,000 | 25-45% | Best Value! High demand. |
| 2TB | ₩180,000 - ₩250,000 | ₩350,000 - ₩420,000 | 30-50% | Excellent for game libraries. |
| 4TB | ₩350,000 - ₩500,000 | ₩700,000 - ₩850,000 | 30-55% | Rarer, but massive savings. |
B. SATA SSDs
My Take: Honestly, SATA SSDs are a hard sell used unless the price is dirt cheap. They're mostly for older systems or secondary storage where speed isn't paramount. I recently sold a Samsung 860 EVO 500GB for a mere ₩40,000 to an elderly gentleman upgrading his old laptop.
Key Brands: Samsung (870 EVO, 860 EVO), Crucial (MX500), Western Digital (Blue 3D NAND).
| Capacity | Used Price Range (KRW) | New Price (Online) (KRW) | % Saving | Notes |
| 250GB | ₩20,000 - ₩30,000 | ₩50,000 - ₩60,000 | 40-60% | Only for very basic use. |
| 500GB | ₩35,000 - ₩50,000 | ₩70,000 - ₩90,000 | 30-50% | Still decent for older systems. |
| 1TB | ₩60,000 - ₩80,000 | ₩120,000 - ₩150,000 | 40-50% | Budget mass storage. |
2. Central Processing Units (CPUs): The Brains of the Operation
The used CPU market is fantastic right now if you're looking for last-gen power without the brand-new price tag. Both Intel and AMD offer compelling options.
A. Intel CPUs
My Take: I recently upgraded from an i7-10700K to an i7-13700K. Selling the 10700K (with a decent cooler) for ₩180,000 was easier than expected on 당근마켓, as there are still plenty of Z490/Z590 motherboard users. For my new build, I actually found an i7-13700K used at Techno Mart for ₩400,000, saving me about ₩80,000 off the new price.
Focus Generations: 12th Gen (Alder Lake), 13th Gen (Raptor Lake). 10th/11th Gen for budget builds.
| Model | Used Price Range (KRW) | New Price (Online) (KRW) | % Saving | Socket | Notes |
| i5-12400F | ₩100,000 - ₩130,000 | ₩180,000 - ₩210,000 | 30-50% | LGA1700 | Excellent budget gaming. |
| i7-12700K | ₩180,000 - ₩230,000 | ₩300,000 - ₩350,000 | 25-40% | LGA1700 | Strong all-rounder. |
| i7-13700K | ₩380,000 - ₩450,000 | ₩480,000 - ₩550,000 | 15-30% | LGA1700 | High-end, still holds value well. |
| i9-13900K | ₩550,000 - ₩650,000 | ₩700,000 - ₩800,000 | 15-25% | LGA1700 | Top-tier, often paired with high-end mobo/cooler. |
B. AMD CPUs
My Take: AMD's Ryzen 5000 series (AM4) is now the king of budget used builds. I've seen countless Ryzen 5 5600X chips go for around ₩100,000. For AM5, the Ryzen 7000 series CPUs are just starting to show up used, and they're fantastic value for those building a new platform.
Focus Generations: Ryzen 5000 Series (AM4), Ryzen 7000 Series (AM5).
| Model | Used Price Range (KRW) | New Price (Online) (KRW) | % Saving | Socket | Notes |
| R5 5600X | ₩90,000 - ₩120,000 | ₩160,000 - ₩200,000 | 30-50% | AM4 | Best Value AM4! |
| R7 5800X3D | ₩220,000 - ₩280,000 | ₩350,000 - ₩400,000 | 25-40% | AM4 | Still a gaming beast. |
| R5 7600X | ₩180,000 - ₩230,000 | ₩280,000 - ₩350,000 | 20-40% | AM5 | Entry to AM5, solid performance. |
| R7 7800X3D | ₩400,000 - ₩480,000 | ₩550,000 - ₩650,000 | 15-30% | AM5 | Current gaming king, high demand. |
3. Random Access Memory (RAM): The System's Short-Term Memory
RAM prices have been fluctuating, but the divide between DDR4 and DDR5 is clearer than ever on the used market.
A. DDR4 RAM
My Take: DDR4 is still abundant and cheap, especially 3200MHz CL16 kits. I helped a friend put together a budget gaming PC last month, and we snagged a Corsair Vengeance LPX 16GB (2x8GB) 3200MHz kit for just ₩45,000 at Techno Mart. It was a no-brainer!
Key Brands: Samsung, SK Hynix, Micron (Crucial), Corsair, G.Skill, TeamGroup.
| Capacity | Speed | Used Price (KRW) | New Price (Online) (KRW) | % Saving | Notes |
| 8GB (1x8) | 2666-3200MHz | ₩15,000 - ₩25,000 | ₩30,000 - ₩40,000 | 20-50% | Basic office/HTPC. |
| 16GB (2x8) | 3200-3600MHz | ₩40,000 - ₩60,000 | ₩70,000 - ₩100,000 | 25-50% | Best Value! Standard for gaming. |
| 32GB (2x16) | 3200-3600MHz | ₩70,000 - ₩100,000 | ₩130,000 - ₩180,000 | 30-50% | For heavy users/workstations. |
| 64GB (2x32) | 3200-3600MHz | ₩140,000 - ₩200,000 | ₩250,000 - ₩350,000 | 25-40% | Niche, but good savings. |
B. DDR5 RAM
My Take: DDR5 is still a premium, but used prices are starting to become attractive. I've seen 32GB (2x16GB) 6000MHz kits pop up for ₩140,000-₩180,000 – a significant saving over new, especially for higher speeds and tighter timings. It's crucial to check the timings (CL) for DDR5, as they greatly impact performance.
Key Brands: Samsung, SK Hynix, Micron (Crucial), Corsair, G.Skill, TeamGroup.
| Capacity | Speed (CL) | Used Price (KRW) | New Price (Online) (KRW) | % Saving | Notes |
| 16GB (2x8) | 5200-6000MHz | ₩80,000 - ₩110,000 | ₩130,000 - ₩180,000 | 20-40% | Entry-level DDR5. |
| 32GB (2x16) | 5600-6400MHz | ₩140,000 - ₩200,000 | ₩230,000 - ₩300,000 | 20-40% | Sweet Spot! For most AM5/LGA1700 builds. |
| 64GB (2x32) | 5600-6000MHz | ₩280,000 - ₩380,000 | ₩450,000 - ₩580,000 | 20-35% | High-end workstations. |
4. Hard Disk Drives (HDDs): The Archival Workhorses
HDDs are no longer primary drives for most, but for bulk storage of games, media, or backups, they're unbeatable on price per TB. The used market is very stable.
My Take: I almost never buy new HDDs anymore. Last month, I bought a used Seagate IronWolf 8TB from a crypto miner (who was liquidating his storage) at Techno Mart for ₩120,000. It had about 10,000 hours on it but 100% health in CrystalDiskInfo. New, it would have been ₩200,000! Always check health and reformat before use.
Key Brands: Western Digital (Red, Black, Blue), Seagate (IronWolf, Barracuda), Toshiba.
| Capacity | Used Price Range (KRW) | New Price (Online) (KRW) | % Saving | Notes |
| 4TB | ₩50,000 - ₩70,000 | ₩90,000 - ₩110,000 | 30-50% | Good for basic file storage. |
| 8TB | ₩100,000 - ₩130,000 | ₩180,000 - ₩220,000 | 30-50% | Best Value per TB! |
| 10TB+ | ₩12,000 - ₩15,000 per TB | ₩18,000 - ₩22,000 per TB | 30-40% | Excellent for NAS/servers. |
5. Special Focus: Samsung RAM - A Korean Staple
Samsung RAM modules are everywhere in Korea, and their used market is robust. They're known for reliability, if not always the highest performance (unless overclocked).
