One graphics card, four chassis sizes. Every machine uses the AMD Radeon RX 6600 XT 8GB, undervolted and tuned card by card before it ships. Choose by how much power your site can actually deliver, not by how many cards you would like.
The table below shows Ravencoin (KawPoW) by default — the best-paying coin these cards can still genuinely compete on. Switch the algorithm and the whole picture changes; try it.
| Model | Cards | Price | Hashrate | Wall power | Per watt | Cost per unit hash | Power/month (CLP) |
|---|
Monthly power assumes 24/7 operation at CLP's 2026 average net tariff of HK$1.406 per unit, before any cooling load.
A normal Hong Kong domestic socket is 13 A — about 2,860 W in theory, but you should not run above roughly 70 % of that continuously. In practice:
All four run from a single 13 A socket — even on the most power-hungry algorithm the V8 only reaches about 860 W. But one circuit takes one machine. For more than one you need an electrician to add a circuit, and if you rent, your landlord's written agreement.
These are open-air frames with axial fans. They are neither quiet nor discreet. Rough guide for a room without air conditioning:
In an air-conditioned room add roughly a third to your electricity bill — that is the power spent removing the heat the machine just produced.
Covers the graphics cards, risers, power supplies, motherboard and frame. Excludes water damage, self-flashed BIOS, and damage from running outside the supplied tuning profile.
Drop it off or send it in. Diagnosis within three working days, and most card swaps are finished the same week. No cross-border returns queue.
Repairs inside the warranty are free. Outside it — or for damage the warranty does not cover — there is a minimum charge of HK$200, quoted on the actual work, with delivery charged separately.
Chargeable or not, every completed repair carries a 6-month warranty on the repair — if the same fault returns, we fix it again at no charge.
You receive the full 72-hour soak test record: per-card hashrate, wall power, core temperatures, and any card that was rejected and replaced during testing.
About second-hand cards — we say it plainly. The RX 6600 XT went out of production years ago, so every card on the market is used or refurbished. We tell you that outright. Each card is stress-tested and re-padded before assembly, and cards that fail testing never leave the bench. But you are buying used silicon, and the warranty exists because of that, not in spite of it.
