Please log in for more thread options socket and a separate 4 pin socket. I also recently purchased a COLORSit 60950 power supply with a 24 pin connector and a separate 6 pin conn. The 24 pin conn splits into a 20 pin and a 4 pin, but the pin configuration does not match the 4 pin socket on the mobo. Have I got something wrong? which piece of H/W is old or incompatible. I can provide pics etc - just totally confused. The 6 pin conn will fit into the 4 pin socket with 2 pins overlapping one side or the other, but I can't believe this is right! TIA.

Please log in for more thread options for the 4 pin 12V CPU power connector. It is provided for compatibility with mainboards that want a 24 pin ATX power connector. Some newer power supplies have an 8 pin 12V connector that can be split into two 4 pin ones. Others have both the 8 pin and the 4 pin connectors. I wasn't able to find any information online on a "60950". Are you sure that's the model number? As your PSU has a 20+4 connector, I assume that it's new enough to also have the 4 pin +12V connector. All of the supplies on a web page that I found: http://www.colors-it.com.cn/03_products/pccase.asp?max_id_search=5 are claimed to be ATX 12V version 1.3 compliant, which means that they include the 4 pin +12V connector. HTH. Address scrambled. Replace nkbob with bobkn. | |||||||||||||||||||||||||||||||

Please log in for more thread options Thanks for response - the number was actually preceded by EN so it was
EN60950, but there is no obvious model number on the box - that was on a label on the side of the casing. The box lists it as COLORSit silent technology 550WATT The 'Features' list on the side of the box says :- . New Version 1.3/Ver.2.03 . Silent and better ventilation . ATX 12V compliant for all kind(sic) of CPU and Mainboard . Input Voltage:115VAC or 230VAC or 115VAC/230VAC . MTBF 50,000 Hours @ 25C Most of that is irrelevant, and it is definitely called up as 230V on the rear of the casing (I am UK based so that is right). Any ideas on that?

Maybe it has an EPS 2x4 connector for 12V (used on servers or dual socket boards). Some of those 2x4 connectors slide apart into two pieces, giving the necessary 2x2 ATX12V connector for a desktop board. I cannot find a detailed picture of the power supply. It appears to be a European product offering, as near as I can tell. There is a http://www.colors-it.com.cn web site, but I cannot see anything that matches there. The practice of the 24 pin sliding apart into 20 + 4 sections, the splitting of a 2x4 into two 2x2 connectors, is not defined in the standards. These non-standard options lead to problems for users who are not aware of the pitfalls that arise from them. Make sure that whatever you use for the 2x2 processor power socket, that it has the two yellow wires and the two black wires, implying the ability to deliver 12V to the Vcore regulator. Your motherboard manual may identify which pins are 12V pins and which ones are ground, so you can compare the color scheme to the identity as defined in the manual. The unique shape of the nylon connector shell, is supposed to prevent at least a percentage of possible mis-connection combinations. Paul >

Please log in for more thread options Right, I'll try to indicate here the shapes of the pins on the 2x2 pin conn
and the 3x2 conn (looking at the pins) Orange Yellow ___ __ | | / \ |___| |___| __ ___ Whereas the 2x2 SOCKET is the opposite version of the PIN arrangement / \ | | |___| |___| Blk Red The 3x2 connector is as below: Yell Yell Yell __ __ ___ / \ / \ | | |___| |___| |___| ___ __ __ | | / \ / \ |___| |___| |___| Blk Blk Blk Hope this displays properly - I have tried to show the angled tops to some of the pins that locate them precisely. >
