Featuring a universal LP4 power connector and innovative bracket design, it supports both 3.3V and 5V cards without requiring drivers, making it an essential tool for professionals looking to seamlessly integrate legacy hardware into modern systems. ## Description This PCIe to PCI Adapter Card lets you use low profile PCI expansion cards in a server or desktop motherboard PCI Express slot. Compliant with PCI Express Specification 1.0a and PCI Specification 2.2, the adapter card connects through a PCIe 1x slot to provide a low profile PCI slot in its place. A spare full size bracket for PCI Express card is also included for use in larger desktop or server PCI Express slots. A versatile solution, the adapter card converts PCIe to PCI or PCI-X; a built-on LP4 power connector links the card to the computer power supply, allowing you to install universal voltage PCI cards (3.3V/5V). The adapter card offers an economical solution that lets you extend the usability of older or extra PCI Bus cards in newer PCIe capable systems. To ensure suitable installation in any low profile server or desktop computer, the PCIe/PCI adapter features an innovative bracket design that adapts and secures the low profile PCI or PCI-X card into the converted slot. ## Features - Innovative bracket design adapts and secures the existing half-height/low profile bracket of the PCI Card - PCI Express base spec 1.0a compliant for up to 250MBps of available bandwidth - LP4 Power Connector Included for Universal Voltage PCI Cards (3.3V/5V) - Compliant with PCI Express to PCI/PCI-X Bridge spec 1.0 - No driver or software installation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0024CV3SA | | Best Sellers Rank | #146 in Internal Computer Networking Cards | | Brand | StarTech.com | | Compatible Devices | Desktop | | Customer Reviews | 4.1 4.1 out of 5 stars (321) | | Global Trade Identification Number | 00065030834629 | | Hardware Interface | PCI | | Item Dimensions L x W x H | 5.3"L x 2.8"W x 0.8"H | | Item Weight | 0.05 Kilograms | | Manufacturer | StarTech.com | | Mfr Part Number | PEX1PCI1 | | Model Number | PEX1PCI1 | | Operating System | OS Independent; No additional drivers or software required | | Style Name | PCI Express to PCI | | UPC | 065030834629 | | Unit Count | 1.0 Count | | Warranty Description | 2 Years | ## Product Details - **Brand:** StarTech.com - **Hardware Interface:** PCI - **Item Weight:** 0.05 Kilograms - **Product Dimensions:** 5.3"L x 2.8"W x 0.8"H - **Style:** PCI Express to PCI ## Images ![StarTech.com PCI Express to PCI Adapter Card - PCIe to PCI Converter Adapter with Low Profile / Half-Height Bracket , TAA (PEX1PCI1) - Image 1](https://m.media-amazon.com/images/I/81OqGYUokoL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: I have a usb 3.0 pcie card but only a pci slot remaining. will this adaptor limit the speed of the usb 3.0? either way i need the extra 4 usb slots.** A: I have done exactly what your proposing but the answer is.... Yes it will severely limit the benefit and performance of the USB 3.0. I have done it simply to provide compatibility (connectability with USB 3.0) and use a PCI port when nothing else was available. Max theoretical Bus speeds are as follows and you can see a large difference between PCI and PCI-Express (and this is especially so with later and faster generations)...PCI 1056 Mb/s AGP 8X 2,133 Mb/sPCI Express 1x 2,500 Mb/sPCI Express 4x 10,000 Mb/sPCI Express 8x 20,000 Mb/sPCI Express 16x 40,000 Mb/sAt its most basic USB 3.0 is 5000 Mb/s / PCI is 1056 Mb/s and PCI-E x1 (Gen 1) 2,500 Mb/s or 5,000Mb/s (Gen II) so you can see that indeed even multiple port USB3.0 using PCI-E x1 (Gen 2) will have trouble keeping up with more than one USB 3.0 port. Hence why there are some companies producing PCIE x4 4 Port USB 3.0 cards (but they cost a lot more). However in comparison with USB 2.0 the USB 3.0 PCI-E/PCI Adapter limited to 1056Mb/s is still much better than the alternative single USB 2.0 High Speed 480Mb/s....So indeed this option I use and you are considering is better than that by a factor of 2 (theoretically). ANd USB3.0 provided more power so some USB 3.0 external drives will not work from USB 2.0 without external power, and this solution also alleviates that issue. Hope that helps. **Q: I'm wanting to add my old pci soundcard, a creative soundblaster audigy to my new pc. has anyone tried this? will it work?** A: It should work but it is really designed for half height cards and the creative soundblaster audigy card is not really a half height card but you may be able to shorten the end mounting plate of the card so that it will fit. **Q: Will this adapter alllow me to write to a pcmcia memory card, or only read from a memory card?** A: The CB2EC will allow you to use CardBus cards as if they were in a native CardBus slot. You will be able to read and write to these card. However the CB2EC will only support 32-bit Type I/II CardBus cards. Nick, StarTech.com Support **Q: my pci port only has 1 "notch" in it and I see this has 2, will it still work?** A: Yes - the two slots in the card allow it to be plugged into either a 32-bit 3.3 Volt PCI slot or a 32-bit 5 Volt PCI slot. ## Frequently Bought Together - StarTech.com PCI Express to PCI Adapter Card - PCIe to PCI Converter Adapter with Low Profile / Half-Height Bracket , TAA (PEX1PCI1) - SATA to 4 Pin Power Cable Adapter 3 Pack SATA 15 Pin Male to Molex LP4 Female Power Cable -7-inch - StarTech.com 12in SATA to LP4 Power Cable Adapter F/M - SATA to LP4 Power Adapter - SATA Female to LP4 Male Power Cable - 12 inch (LP4SATAFM12) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/2406030-startech-com-pci-express-to-pci-adapter-card-pcie-to](https://www.desertcart.com.br/products/2406030-startech-com-pci-express-to-pci-adapter-card-pcie-to) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-06-23*
