These tests help verify stable output and protection performance, but testing does not confirm physical compatibility. CHECK YOUR ORIGINAL PSU LABEL, SIZE, MOUNTING POINTS, CONNECTORS, AND CABLE LENGTHS BEFORE ORDERING. - 🔧 [REPLACE ONLY AFTER EVERYTHING MATCHES] Before removing the old PSU, take photos of its mounting position and every cable connection. Power off and unplug the computer, remove the side panel, disconnect the old power supply, install the replacement, and reconnect only the matching connectors. If any connector, mounting point, cable length, model number, part number, or case type differs from the original, STOP INSTALLATION AND CONTACT US BEFORE POWERING ON. Sending us clear photos of your original PSU label and connectors is the easiest way to CONFIRM COMPATIBILITY BEFORE PURCHASE. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07C7CVM4M | | Best Sellers Rank | #109 in Computer Power Supplies | | Brand | POINWER | | Compatible Devices | Personal Computer | | Connector Quantity | 5 | | Connector Type Used on Cable | 4_pin_atx, ATX, SATA | | Cooling Method | Air | | Current Rating | 4 A | | Customer Reviews | 4.5 4.5 out of 5 stars (1,051) | | Form Factor | ATX | | Item Dimensions | 9.45 x 2.9 x 2.5 inches | | Item Highlight | H240AS-01 H240AS-00 L240AS-00, 2TXYM 3WN11 CCCVC 3RK5T D240ES-00, fits 760 960 990 9010 SFF, not MT/DT | | Manufacturer | POINWER | | Maximum Input Voltage | 240 volts | | Mfr Part Number | H240ES-01 H240AS-01 PH3C2 2TXYM RV1C4 | | Minimum Input Voltage | 100 volts | | Model Name | f79td | | Model Number | H240AS-00 H240ES-00 D240ES-00 AC240AS-00 | | Number of Fans | 1 | | Number of Items | 1 | | Number of Packs | 1 | | Output Wattage | 240 watts | | Power Supply Design | Internal | | System Bus Connector Type | 24 Pin | | UPC | 743070991419 | | Unit Count | 1 Count | | Wattage | 240 watts | ## Product Details - **Brand:** POINWER - **Compatible Devices:** Personal Computer - **Connector Type:** 4_pin_atx, ATX, SATA - **Cooling Method:** Air - **Form Factor:** ATX - **Item dimensions L x W x H:** 9.45 x 2.9 x 2.5 inches - **Model Name:** f79td - **Output Wattage:** 240 watts - **Power Supply Design:** Internal - **Wattage:** 240 watts ## Images ![240W Power Supply for Dell OptiPlex 390 790 3010 7010 (SFF Only) - Image 1](https://m.media-amazon.com/images/I/71n8eX2b0aL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Will this work for a dell optiplex 9010 desktop and if so can anyone verify it does?** A: I have installed in OptiPlex 3010, 7010, and 9010 SFF pc's and it works perfectly. **Q: I wan to know is this model is compatible with ac240as-01? i can see is compatible with ac240as-00.** A: Yes.
