Question about Lenovo ThinkCentre M710t Power Supply Expansion
I own a Lenovo ThinkCentre M710t that I use for recording music using a Firewire audio interface. I need to connect my Firewire PCI-e card to the PSU via an LP4 cable, as the card supports this connection. The card is a Startech model (PEX1394B3). My problem is with the PSU in my machine—it's a very basic slimline unit without any extra ports for future upgrades. Can anyone tell me if the PSU I have (LITEON PA-2182-2) is a standard form and if I could find an upgrade for it? Also, is it possible to connect the Mobo power or CPU fan power to my FW card using a daisy chain, if such a cable exists? Thanks.
The PSU resembles a semi-modified TFX model, though it includes its own proprietary connectors and only the essentials needed for board connection—not an extra card with more power input. The motherboard features a breakaway design allowing storage/SATA drives to be powered from the rest of the unit. I wouldn't suggest attempting to reverse engineer the power output cables.
If you believe your whole system is replaceable, you can purchase this option:

then adapt the SATA end to fit a male Molex 1 (LP4, 4-pin, large drive power) connector and connect it to your PCIe card.
For what it's worth, you're asking about the specific part you're considering replacing. It seems like you could replace it with a similar TFX unit, such as this one. The size and screw holes match closely to the existing one, and it even has a Molex connector, which is a plus. I'm wondering if you're correct in assuming an "LP4" connector is equivalent to a 4-pin Molex. The main concern is that the MB connector is 24 pins, while your board only accepts 10 pins, but there might be a converter cable that can handle it.
