![]() In fact, according to your Motherboard Manual, The computer will not Boot up if the 12v (8 Pin CPU Power ) is not connected. ![]() Some motherboards have both 4 & 8 Pin Aux Power (CPU) connectors. Since the operation and speed of the processor is voltage dependent, the processor is supplied to the nearest thousandths (sometimes even ten thousandths), which cannot be guaranteed by the voltage converter in the power supply itself, as it provides power from a coarser and not so fine way. The 8 pin Power connector is what give power to the CPU. Motherboards and especially high-end and overclocking-oriented motherboards have a complex conversion and filtering circuit in their VRM (Voltage Regulator Module) to fine-tune the voltage that is supplied to the processor. The answer is simply by margins and by control. This makes everything more confusing if possible because if the processors work in ranges that barely exceed 1 volt of current voltage, why then do they give 12V? Thus, if for example the motherboard needs 1.35V to service the RAM memory, it will use the + 3.3V rail since it is the closest, but when we talk about the USB ports for example, then it will use the rail of + 5V without the need to convert anything. Power Supply includes: 1 x Main connector (20+4Pin) 1 x 12V (P4) 4 x Peripheral. The goal of doing all of these conversions is to provide the motherboard with voltages that are closest to what it needs, so that the motherboard’s voltage conversion effort takes minimal work. I just got finished putting everything in the case and when I go to unwrap the tied PSU cords I realized there is only a 4 pin for the CPU and the motherboard has a 8-pin CPU power plug. I disconnected one and it still isn't working.The answer to this question lies in how the power supply works, but also in how both the motherboard and the processor work the power supply converts the alternating current that reaches it into 12V direct current, and then internally converts that voltage back on the 5 and 3.3 volt rails that are the ones that supply -among others- to the ATX connector. I thought it would be smart to do it, but the system isn't working. Specifically regarding the motherboard, there are two connectors that go directly to it, the EPS that can be 4 or 8 pins (that is why it is called 4 + 4 pins), and you should know that some high-end motherboards require two of these connectors, and the 20 + 4-pin ATX, which continues with that split design despite the fact that only some low-pow. BUT, on the same wire,there is another set of connectors (4+4) that you could curve back and connect to the other 12V ATX CPU slot. So the CPU cable has the end that connects to the PSU, then it has an 8-pin connection to go into one of the 12V ATX CPU slots. We used the EVGA included tool to test the power supply, and it powered up the case fans and therefore we are thinking the power supply is not bad, something is done wrong. This is what is bugging me though - I thought I "was done" and the system won't power up, not at all. If your power supply has enough cables then yes definitely connect both. 1 mobo is asrock x470 taichi psu is seasonic prime ultra gold 650w cpu is ryzen 7 2700x and my gpu is palit gtx 680 Jetstream so my problem is that my psu only have 8pin cpu connector and my. BabyBlu (Primary): CPU: Intel Core i9 9900K up to 5.3GHz, 5. That is of course unless you intend to use a 12900K which can certainly use that much power when unleashed. ![]() If you need to connect an 8-pin socket to an 8-pin socket, it shouldn't matter though. ![]() ![]() The right connector (4+4) is the one you connect to the motherboard. The left connector (8) is the one you connect to the PSU. Refer to the user manual of your PSU to confirm this. Thanks everyone, i just figured if I have the power, motherboard, and cord capability to use both 8pin CPU power slots easily, and I have a semi hi performance CPU in the 4790K, why not connect both right ?īut of course didn't want to connect both if its a problem or incorrect / wrong thing to do etc A single 8 pin EPS connector can supply 235 Watts of continuous power. The bottom pins are connected with black cables and are designed for GND. ![]()
