In AdsPower the proxy lives inside each browser profile. Open New Profile, go to the Proxy tab, set Proxy setting to Custom, choose the type, then paste host and port into Host:Port and the login into Proxy username and Proxy Password. Check Proxy confirms the exit IP before you save.
New Profile → Proxy tab → Proxy setting: Custom
Paste host:port:user:pass into the Host:Port box and AdsPower fills the username and password itself.
Open the AdsPower client and click New Profile in the top-left corner. The New Browser Profile page opens with the General tab selected; switch to the Proxy tab.

Set Proxy setting to Custom. Pick the Proxy type that matches the port you will use (HTTP for the HTTP port, Socks5 for the SOCKS5 port). Type the gateway host before the colon and the port after it in Host:Port, then the username and password in Proxy username and Proxy Password. Leave Change IP URL empty: a sticky username keeps the IP for you.

Click Check Proxy next to the Host:Port field. AdsPower prints Connection test passed with the exit IP, country, city and time zone. If it fails, confirm the type matches the port and that the line has no trailing space.

Check Proxy, next to Host:Port. A green Connection test passed line shows the exit IP and location.
Click OK at the bottom to save the profile, then open it from the Profiles page. Every request from that profile leaves through the line you pasted. To confirm from inside the browser, open the QuantumProxies IP checker and compare the IP with the one AdsPower showed.
Copy the line from the dashboard (Proxies, your plan, the proxy generator) rather than typing it: it already carries the country, the session id and the session length in the username. The table shows what each field holds.
| Plan | Host | HTTP port | SOCKS5 port | Username shape |
|---|---|---|---|---|
| Residential Premium | residentialpremium.quantumproxies.io | 8080 | 1080 | USER-country-us-sid-k3f9a1b2-ttl-60m |
| Residential Basic | residentialboson.quantumproxies.io | 9000 | from the generator | USER-country-us |
| Mobile | mobile-us.quantumproxies.io (also -eu, -as, ww) | 8080 | 1080 | USER-country-us-type-mobile |
| Datacenter (per GB) | datacenterboson.quantumproxies.io | 9999 | 10000 | USER-type-datacenter-country-de |
| IPv6 | ipv6.quantumproxies.io | 1001 | from the generator | USER-country-us-package-ipv6 |
| ISP (dedicated IP) | the IP of your line | 8000 | on the plan page | the line's own login |
The password is the one the generator prints next to the username. Pick HTTP or SOCKS5 in the tool and use the port of that column; a port from the other column is the most common reason a check fails. USER and the session id are placeholders for your own values.
Set Proxy type to Socks5 and use the SOCKS5 port of your plan (1080 on Residential Premium and Mobile, 10000 on Datacenter). Host, username and password stay the same as for HTTP.
Leave Change IP URL empty and control the session from the username instead: a new sid gives a new IP, a ttl keeps it. AdsPower's Rotating Proxy tab is for IP-rotation links; our rotation links also work there if your plan has them.
Nine times out of ten the Proxy type does not match the port, or the line was pasted with a space at the end. Switch the type, re-paste the line, and check again. If the plan is out of traffic the test fails too.
Skip the marketing. QuantumProxies.io publishes a machine-readable site map, Markdown for every page, a free MCP server, and APIs billed from the same balance as your proxies.
