We are looking to upgrade our T5810 with 2 GTX 1080s and thus also with a standard ATX PSU. Now I read a lot about Dell's Motherboards having proprietary power connectors. As far as I've seen I need 2 connectors: 20 pin (main power "p1-p2") 10 pin (CPU power "p5-p6") So my questions are: is the 20 pin connector proprietary ? (i think so?
The Vostro 200 does not use a Dell proprietary power supply, you can use most generic ATX power supply units, with either a 24-pin or 20+4-pin main motherboard power connector. Note: You require a power supply with a minimum of four SATA power connectors.
28. 24-pin power 1 connector 17. 24-pin power 2 connector - Can anybody confirms that the 24-pin power 1 connector is 12V connectors on one side and ground connectors on the other? For this connector I will have to make some sort of adapter for a standard ATX power supply. - Does anyody know if the 24-pin power 2 connector is a standard ATX pinout?
Section 4.1—Main Power Connector changed from 20 pin to 24 pin to support PCI-Express* requirements. Section 4.1.1—Removed Aux Power Connector Recommendation if using a power supply designed using ATX12V Power Supply Design Guide Rev 2.0 or greater. Section 4.1.4—Update 3.3 V tolerance. Page 20 of the ATX 2.2 standard has a 24 pin connector.
The black wires are ground. White wires are 12V and The green wire is the power on and the grey wire is 12V standby power. To adapt a power supply OUTSIDE THE case requires an adapter. its not passive and requires conversion. Optiplex 3020 9020, Precision T1700, Power Edge T20 also use an 8 pin connector for this.
So the stock config for the PCIe aux power is 2x6pin. first i tried a pair of 6-to-8 pin adapters. no dice. wouldn't get past bios post. then reading up on it, there is an AUX CPU power on the PSU distribution board. so got a pair of cables off of ebay, one that has 2x8pin aux off of the original PCIe aux power port on the distribution board ...
Most generic standard ATX power supply units can be installed, with either a 24-pin or 20+4-pin main motherboard power, as the XPS 8700 has an open back panel, with or without the on/off switch. Note: A power supply with five SATA power connectors, is needed. It has been reported that it's better to buy a power supply with a depth of around 5.9".
What controls these two states is the PS_ON# line. Logic on the motherboard, powered by the 5v_STANDBY line, pulls PS_ON# low permanently to enable the power supply main output, and releases it high to disable the main output. There are two converters inside an ATX power supply: The main converter which provides +12V, +5V, +3.3V, -12V and -5V.
These higher power psu have 2x4 pin cpu +6 pin mobo connectors and one to two 6 pin connector for gpu (360w has one, 500w two). You connect one of the 2x4 pin cpu to 5070, leaving the other 4 pin connector alone (5070 cpu does not require additional power).
Actually page 72 of the owners manual for the R16 under the FRU section about removing the power supply shows an image with a 6 pin ATX connector but is using 5 "with a 5 pin connector plugged in" probably for the 500w and 1000w power supply, the 1350w comes with the 6 pin.
