PowerCompute Miner Refresh Expected to Deliver Nearly 39% More Hashrate Per Machine Replaced
PowerCompute expects an 11.8% hashrate increase and higher revenue capacity using roughly the same power and about $400,000 of capital.
Rhea-AI Summary
PowerCompute (PWCM) plans a fleet refresh expected to raise total Bitcoin mining hashrate from 771 PH/s on June 30, 2026 to about 862 PH/s, an 11.8% increase, by October 2026.
The company intends to install 1,000 Bitmain Antminer S19 XP miners at its Oklahoma site by September 30, replacing S19J Pro units, which will be redeployed to Mississippi to displace S19 units averaging 95 TH/s, lifting hashrate to roughly 822 PH/s (+6.6%). On September 22, 2026 it ordered 940 more S19 XP miners to replace additional 95 TH/s units in Mississippi, targeting approximately 862 PH/s when installed in October. Each new miner replaces a 95 TH/s machine with a 132 TH/s unit, improving efficiency from about 34 to 21.5 joules per terahash. The company estimates around $1.2 million in annual incremental revenue capacity from these machines and a total acquisition cost of about $400,000, funded from cash and Bitcoin holdings. As of August 31, 2026 it held 323 Bitcoin valued at about $27.8 million.
Positive
- Total hashrate expected to rise from 771 PH/s to about 862 PH/s (+11.8%) versus June 30, 2026
- Initial upgrade to 1,000 S19 XP miners lifts hashrate to about 822 PH/s (+6.6%)
- Per-machine hashrate increases from 95 TH/s to 132 TH/s, nearly +39% on similar power draw
- Energy efficiency improves from ~34 to ~21.5 joules per terahash on replaced units
- Incremental revenue capacity estimated at about $1.2 million per year from the new machines
- Upgrade cost for 1,940 miners is approximately $400,000, funded from cash and Bitcoin holdings
- Bitcoin treasury of 323 BTC valued at about $27.8 million as of August 31, 2026
Negative
- Capital outlay of approximately $400,000 required for miner purchases
- Additional 3 MW capacity in Mississippi will require further infrastructure and capital to utilize
News Explained
Beyond the miner refresh already described, PowerCompute says up to 3 megawatts of energized capacity in Mississippi is available for expansion, which would require additional infrastructure and capital.
