AP-MPS3ATX40 for specific Dell, HP, Compaq, E-Machines and Gateway Tower computers
The Athena Hercules AP-MPS3ATX40 is a basic power supply compatible with many OEM (branded); Dell, HP, Compaq, E-Machines and Gateway Tower computers. This 400 Watt power supply is designed for Tower systems (Vertical) and is NOT a replacement for the small proprietary power supplies for Dell desktop (Horizontal) systems.
Micro PS3 ATX Form Factor
The AP-MPS3ATX40 is specifically designed for Dell, HP and other OEM systems. The form factor is Micro PS3 ATX, which is the same height and width of a normal PS2 ATX power supply, however the depth is more shallow and the connectors, pins and voltage are different. There is also no power switch on the AP-MPS3ATX40 as the branded computers control power on/off through system software.
Dell 16 or Dell X cable may be required for some Dell systems
This 400 watt power supply will work with most Dell Tower systems, and many HP, Compaq, E-Machines and Gateway Tower computers. Some Dell systems will require the Dell 16 or Dell X cable. This power supply listing does NOT include the optional cables. See the 2 additional listing that do include the optional cables; the Dell 16 cable and the Dell X cable. Make sure you choose the correct listing. See the compatibility list or the Search by Model number section for your manufacturers brand name to quickly navigate to the list of compatible power supplies, first by model, and then by part number.
When more power is needed
Some systems require more power and therefore require the 470 Watt or a 550 Watt power supply. More power is a good thing when it comes to power supplies. Your computer will only pull what it needs, but having more power available means you can add more peripherals, upgrade your video card, and allow the system to run more stable with more consistent power.
Sometimes confusing motherboard connector 20/24 pin
The AP-MPS3ATX40 supports 20 pin or 24 pin ATX v2.2 motherboards. The motherboard connector is designed to work with both, meaning the last 4 pins of the 24 pin connector pop off for 20 pin motherboards. This sometimes confuses customers as they think they received the wrong power supply.
Video connectors (PCI Express, HP)
The AP-MPS3ATX40 also has a PCI Express 6 pin connector (to provide power to a PCI Express VGA card) and a 4 pin connector specifically for HP Video connections.
Step Up Options:
If you need the EPS-12V 8-pin connector for a Xeon motherboard, see the 470 Watt and 550 Watt Athena models.
If you are upgrading your video card and need 2 PCI Express video connectors, choose the new Athena 550 Watt AP-MPS3ATX55EP8. That model is also 80PLUS Certified.
Warranty and PCPOWERZONEs quality feedback
The AP-MPS3ATX40 is supported with a One Year Warranty. We have been selling this power supply for several years and have had great success with it.
