Single 8 pin cable
Single 8 pin cable
The PSU supports only one GPU cable. Using 3070 or 3070ti may be risky. Check the maximum GPU capacity it can handle.
I own an MSI A650BN psu with only one GPU cable. I was considering using a 3070 or 3070ti, is this a risky decision?
Thumbrule, if you lack the right connectors from your PSU for these parts, you either have:
a) the incorrect PSU for the task
or
b) the incorrect components for the PSU.
You should consider upgrading to a model with native 12VHPWR connectors or dedicated harnesses suitable for the RTX3070Ti adapters.
What is the maximum GPU capacity this psu supports?
How long has the PSU been in use and what has it been handling over time?
It should include two 8-pin connectors on one cable according to the guidelines. This setup supports around 300W plus 75W from the motherboard. As long as the GPU doesn’t require more than dual 8-pin, it should function fine.
Is it accurate that you included the correct model number for the power supply? The records mention two 6+2 video cables.
I'm sorry, but I don't understand your question. Could you please clarify what you're asking about?
Single rail offers advantages. It prevents overcurrent issues based on the existing connections, allowing only the maximum power draw on the 12V rail. This is what most modern PSUs provide. Comparing DC-DC single rail systems to older multi-rail or group-regulated ones makes sense. The best choice hinges on the overall system setup. If you have a decent consumer CPU that won’t exceed 200W while the GPU runs at full capacity, it should work well.
5500 is quite light and should work fine.
Some people raise objections about daisy chained cables, but they often overlook the real details. They opt for a thicker wire that can handle more current. Usually, four 12V 16-gauge wires are used, which is more than enough for two 8-pin connectors, each with three 18-gauge wires.
Another perspective: an 8-pin EPS cable supports up to 336W, while each 8-pin PCIe connector handles about 150W. Generally, power supplies use the same connector at both ends (if modular) and can be swapped easily.
Four 16-gauge wires should easily manage 640W at 12V before problems arise. Even in the worst scenario with 18-gauge wire, it should still handle around 360W without significant temperature or voltage drops.
