When a hardware fault is detected during POST, the BIOS generates a series of beeps through this speaker to indicate the error type (RAM failure, GPU missing, CPU error, etc.). Essential for diagnosing PC build and repair issues without a display, it is a standard component for PC builders, repair technicians, and system integrators.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector\u003c\/td\u003e\n\u003ctd\u003e4-pin header (fits standard SPKR motherboard header)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeaker Type\u003c\/td\u003e\n\u003ctd\u003ePiezoelectric buzzer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC (from motherboard SPKR header)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSound Output\u003c\/td\u003e\n\u003ctd\u003eAudible beep tones for POST codes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e~15–20cm (varies by variant)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eATX, Micro-ATX, Mini-ITX motherboards with SPKR header\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e2 pieces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eCommon POST Beep Codes (AMI BIOS)\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBeep Pattern\u003c\/th\u003e\n\u003cth\u003eMeaning\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1 short beep\u003c\/td\u003e\n\u003ctd\u003ePOST successful (normal boot)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2 short beeps\u003c\/td\u003e\n\u003ctd\u003ePOST error (check display)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1 long + 2 short\u003c\/td\u003e\n\u003ctd\u003eVideo card \/ GPU error\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1 long + 3 short\u003c\/td\u003e\n\u003ctd\u003eVideo memory error\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3 long beeps\u003c\/td\u003e\n\u003ctd\u003eRAM not detected\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContinuous beeping\u003c\/td\u003e\n\u003ctd\u003eRAM or power supply failure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo beep\u003c\/td\u003e\n\u003ctd\u003eSpeaker not connected or PSU failure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhy Use a PC Internal Speaker?\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePOST beep code diagnosis\u003c\/strong\u003e — identify hardware faults without a display (essential for headless server builds)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo-display troubleshooting\u003c\/strong\u003e — diagnose RAM, GPU, and CPU issues before connecting a monitor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePC build verification\u003c\/strong\u003e — confirm successful POST with a single beep before installing OS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLegacy compatibility\u003c\/strong\u003e — many modern motherboards still include SPKR header for this purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-pack value\u003c\/strong\u003e — one for current build, one spare for future repairs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible With\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eATX motherboards\u003c\/strong\u003e: Intel and AMD ATX boards with SPKR 4-pin header (standard location near front panel headers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicro-ATX \/ Mini-ITX\u003c\/strong\u003e: Most mATX and Mini-ITX boards include SPKR header\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBIOS types\u003c\/strong\u003e: AMI BIOS, Award BIOS, Phoenix BIOS, UEFI (with legacy beep code support)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNOT compatible with\u003c\/strong\u003e: Motherboards without SPKR header (some ultra-compact boards omit it)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eQ: Where is the SPKR header on my motherboard?\u003c\/strong\u003e\u003cbr\u003eA: The SPKR (speaker) header is typically located near the front panel connector group (F_PANEL) at the bottom-right of the motherboard. It is a 4-pin header labeled “SPKR” or “SPEAKER”. The connector is keyed — align the “+” wire to pin 1 (positive). Refer to your motherboard manual for the exact location and pinout.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: My PC has no beep speaker — how do I diagnose POST errors?\u003c\/strong\u003e\u003cbr\u003eA: Without a speaker, POST errors are indicated by LED codes (Q-LED on ASUS, EZ Debug LED on MSI) or a POST code display (2-digit hex display on some boards). Install this speaker to enable beep code diagnosis. If your motherboard has no SPKR header, use a POST card (PCI\/PCIe diagnostic card with 2-digit display) for error code readout.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: My PC beeps but I don’t know the code — where do I look up beep codes?\u003c\/strong\u003e\u003cbr\u003eA: Beep codes are BIOS-specific. Check your motherboard manual for the BIOS type (AMI, Award, Phoenix) and look up the beep code table. Common resources: AMI BIOS beep codes at ami.com, Award BIOS codes in the motherboard manual. Count the beeps carefully — distinguish between short beeps (0.5s) and long beeps (1s).\u003c\/p\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e2× PC Motherboard Internal Speaker Buzzer (4-pin header, with cable)\u003c\/li\u003e\u003c\/ul\u003e","brand":"Keszoox","offers":[{"title":"Default Title","offer_id":46991470756075,"sku":"\u003cnone\u003e","price":7.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/mini-plug-speaker-buzzer-pc-motherboard.webp?v=1761633921","url":"https:\/\/keszoox.com\/products\/pc-motherboard-internal-speaker-buzzer-post-beep-4pin-2pack","provider":"Keszoox","version":"1.0","type":"link"}
