Will this PS (EG365AX-VE) work with a GA-EP35 motherboard?
I'm looking to upgrade my system from the current P4 to a new C2D
based around an E7200 and a Gigabyte GA-EP35 motherboard. It will also have a low end video card (probably an ATI 4670), probably 2GB of PC6400 RAM, a HD and a CDROM drive. That's a fairly low power system so I'm wondering if I can use my old power supply (an Enermax EG365AX-VE ATX V1.2). I know it has enough power (350Watts) but I don't know if it will work with the Gigabyte GA-EP35. Does anyone know if this will work with the EP35 or does it not have the proper connectors? |

The 4670 is listed here as 59W. I'd prefer to get an actual measurement (xbitlabs.com), but they take their time when new stuff comes out. EG365AX-VE +3.3V @ 32A; +5V @ 32A; -5V @ 1A; +12V @ 26A; -12V @ 1A; +5VSB @ 2.2A E7200 is 65W TDP, and the real power might depend on what kind of overclocking you'll be attempting. I'd say you're at 13.6A from the 12V rail. That gives 163.2W when multiplied together. Add 50W for the motherboard and RAM, 12.5W for the 5V rail on the drives, and 10W for standby (+5VSB), brings the total power to 235.7W. I don't see a problem here. Paul |

That doesn't address the real issue that I was getting at which is what type of power connector does the motherboard need. The PS is an older ATX power supply and I know the spec has changed over the years so I'm not sure if the Enermax PS will work with a new C2D motherboard. |

The PS is an older ATX power supply and I know the spec has changed over the years so I'm not sure if the Enermax PS will work with a new C2D motherboard. You can plug a 20 pin main connector, into a 24 pin motherboard. The ATX12V 2x2 connector should be the same. If there was a 2x4 ATX12V on the motherboard, you could plug a 2x2 into the marked pins (when a 2x4 ships, usually four of the pins are covered and four are exposed). The deal with the main connector is 1) The 24 pins have four extra pins, and their job is to carry extra current. All the same rails are present, so that part hasn't changed. (No new voltages were introduced.) 2) The most important of the pins on the extra ones, is the 12V pin. When using a 24 pin connector, you have two 12V wires total. Two wires at 6 amps carrying capacity each, would be 12A that could flow to the motherboard if needed. That helps with heavy 12V motherboard loading. 3) PCI Express motherboards have 12V wired to each socket. The socket can supply up to 5A, of which the largest current flow I've seen is 4.35 amps to a video card. If you hook up a 20 pin supply, have one video card installed, and the video card happens to max out the slot power, then you're drawing 4.35 amps plus about 0.5A for fan current, which is less than the 6 amp rating of the single 12V pin on the 20 pin connector. In summary, if you are running an SLI or Crossfire setup, you may want to purchase a 24 pin power supply for your 24 pin motherboard. If the motherboard is only going to have a single video card, then you can survive using a 20 pin connector (and reusing the old supply). Could the rules be violated ? Sure. Someday, someone will invent a smaller PCI Express x1 card, that draws tons of amps. That could upset my assumptions above. But as long as such a card does not exist (and new cards are not being introduced at any great rate), the "one video card, 20 pin connector is safe" rule would seem to apply. In terms of alignment, pin 1 of the 20 pin power supply, goes to pin 1 of the 24 pin motherboard socket. All the unused pins, would be to one side of the connector. The shaped connector pins, should help assure you they're going in the correct holes. The latch won't necessarily align and work properly, depending on its width. 1 10 +-------------+ | | +-------------+ +-----------------+ | | +-----------------+ 1 12 HTH, Paul |
