This official PS3 firmware download provides the latest system software for a PlayStation 3 console or RPCS3. Version 4.93 is verified against Sony's live US update list, and the file checksum below was calculated from the complete Sony-hosted PS3UPDAT.PUP package.
Sony distributes PS3 system software as a PUP package. The same official PS3UPDAT.PUP file can update a physical console or install the firmware libraries required by RPCS3. The download is identical, but the installation path is different. Choose your destination before following any instructions so you do not copy the file to the wrong place or look for a separate, unofficial emulator BIOS.
Use the console's built-in internet update when it works, or prepare a FAT32 USB drive for an offline update. The USB method requires an exact uppercase folder path and the original PS3UPDAT.PUP filename.
RPCS3 does not need a separate BIOS download. It imports Sony's official PUP through File > Install Firmware and extracts the system modules that supported games need.
Downloading the file is only the first part of the update. Before installation, confirm the file name, compare the checksum, and choose the correct workflow. These four checks prevent the most common problems: a browser adding a duplicate suffix, an incomplete download, a USB drive the PS3 cannot read, or an emulator user selecting a compressed archive instead of the PUP itself.
Use the verified button for firmware 4.93. After the required 15-second verification wait, the request goes to Sony's PS3 update server without an EXE, ZIP wrapper, or account wall.
The downloaded item should be named PS3UPDAT.PUP and should be 206,197,916 bytes. If the name ends in .zip, .exe, .iso, or .pup.pup, stop and check the source.
Calculate SHA-256 and compare it with 158471fd834f8ea8036136b6aab43cd86c7ba73d79ca30e0af3c0fe0001cf365. A mismatch means the file is incomplete or different.
For a console, copy the file into PS3/UPDATE on a FAT32 USB drive. For RPCS3, select the PUP directly from File > Install Firmware instead of copying it into a console-style folder.
PS3/UPDATE/PS3UPDAT.PUPUse the archive to identify earlier official firmware releases and their release order. Only version 4.93 currently has a direct source that we verified against Sony's live update list. Historical entries remain reference-only until their files, sizes, and hashes can be independently checked. An old PUP file does not automatically make a console downgrade possible.

A firmware download deserves more scrutiny than an ordinary document because the console or emulator will parse privileged system files from it. We record the exact source URL, byte size, MD5, SHA-256, release date, and last verification date for the latest official package. Those facts let you confirm that the download you received is the same file we inspected instead of relying on a vague safe-download badge.
The current US update list reports system software 4.9300 and points to a Sony-hosted PS3UPDAT.PUP dated March 18, 2026. Our July 13, 2026 verification downloaded all 206,197,916 bytes and produced the SHA-256 shown on this site. Sony serves the legacy update endpoint over HTTP, so checksum verification is especially important after the transfer completes.
Official firmware, hybrid firmware, and custom firmware are not interchangeable labels. The main download on this site is Sony official firmware, commonly shortened to OFW. It is intended for normal system updates and RPCS3 firmware installation. This site does not mix HFW, CFW, NoBD builds, jailbreak packages, game ROMs, or decryption keys into the official download flow.
Do not install an old or modified firmware package merely because its version number looks useful. PS3 downgrade and custom-firmware compatibility depend on console hardware, minimum version, flash type, and the method being used. A wrong package can fail validation or leave the console unable to complete an update.
The latest version reported by Sony's US PS3 update list during our July 13, 2026 check is system software 4.93, internally shown as 4.9300. Sony released the current package on March 18, 2026. Check the visible verification date because Sony can publish another version later.
The primary 4.93 button points to the PS3UPDAT.PUP URL published in Sony's own US update list. PS3 Firmware Wiki is an independent reference and is not an official Sony website. We expose the source and checksum so the relationship is clear and verifiable.
PS3UPDAT.PUP is the standard filename for a PlayStation 3 system software update package. A physical PS3 reads it from the PS3/UPDATE folder on supported removable storage. RPCS3 can import the same PUP through its Install Firmware command. It is not an ISO, Windows installer, or game file.
Yes. RPCS3's official quickstart directs users to obtain PlayStation 3 system software from Sony and install it through File > Install Firmware. You do not need a separately labeled PS3 BIOS. Keep the PUP intact and select it directly in RPCS3.
The site-builder workflow uses an accessible 15-second in-page verification wait for download CTAs. The countdown does not open an advertisement, require an account, or send you to a second confirmation page. When it finishes, the browser requests the verified Sony source URL.
On Windows, open a terminal in the download folder and run certutil -hashfile PS3UPDAT.PUP SHA256. On macOS or Linux, run shasum -a 256 PS3UPDAT.PUP. Compare the complete result character by character with the value on the 4.93 detail page.
Not through the normal update menu simply by choosing a lower version. The console enforces version and hardware rules. Downgrade eligibility depends on the model, minimum factory firmware, flash type, and specialized methods. The archive is a version reference, not a promise that every listed release can be installed over a newer one.
First verify that the drive is FAT32 with an MBR partition, the folders are exactly PS3/UPDATE, and the file is exactly PS3UPDAT.PUP. Then confirm the PUP checksum and try the console's Safe Mode update option if the normal menu cannot detect it. The troubleshooting page provides a complete decision path.
