![]() The Corsair CX 550 and CX 650 can output close to 550w on 12v and 650w yet they still only have 2 pci-e connectors : for example Corsair with their value series, they sold 420w models with one pci-e 6pin and sold 500w or 550w models with 2 x pci-e 6+2pin or something like that.įor example Corsair CX 450 has 448 watts on 12v but only one pci-e connector : ![]() Some manufacturers limit the number of connectors to push people into buying higher wattage models (and spend a few dollars more). ![]() Such systems don't need 6pin or 8 pin connectors so the company placing the order tries to save a dollar on wires and connectors by not including those pci-e connectors. That Seasonic 350w OEM power supply was probably made for a company like HP or Lenovo which used it in a system equipped with a motherboard that had integrated graphics and no pci-e x16 slots, or just one pci-e slot, or it's was a SLIM style desktop which can only host half-height pci-e cards. Obviously we're not talking about high quality power supplies here. So you're telling me that you bought the wrong PSU because it didn't come with a 6 pin?Īnyway, a card that requires a 6 and 8 pin usually uses several hundred watts, so using a 400W chinese power supply to power that would be a horrible idea. so maybe this could still become a problem if the GPU is a real gas guzzler. I used one of these 2x molex to 1x 6 pin in my system and it was just fine. so having a 6 pin or not isn't really a relieable indicator if the psu is powerful or not. That seasonic psu says 350W on the sticker and has no 6 pin but i have seen 300w or even 250w units that had a 6 pin. so lack of quality should not have been the reason why there is no 6pin. Seasonic has a reputation for producing good quality psus AFAIK. I bought a seasonic oem psu (one of the ugly grey ones) wich did not have 6 pin connectors.
