Zotac GTX 1080 AMP paired with dual 8-pin connectors
Hello, thank you for your message. I'm trying to build a budget PC and came across this GPU setup. It uses an 8-pin power connection on the PSU and a single 8-pin PCI power port. My concern is whether the power supply can handle the load—especially since the GPU typically draws around 220W during heavy use, peaking near 230-240W. I noticed the PSU only has one 8-pin PCI slot and a cable that splits from one to two 6+2 pin outputs. Do you think this configuration might be limiting my power supply? Would it be better to get a PSU with two separate 8-pin connections?
I wouldn't suggest using this card with a single 8-pin connector. It could be rated for an average of 220W over one second, but that doesn't guarantee it won't exceed it. Check the PCIE12v consumption chart in this review. Bridged 8+8 or 8+6+2 cables work just fine.
The PSU uses this type of cable, do you mean that? Reference from online where the cable splits near the GPU end.
They usually rely on larger wire gauges to fit the additional 8-pin connector, making the gauge crucial. Many budget power supplies often cut corners on this aspect.
Choose a reliable power supply such as a 750W unit for high power needs; better cables won't compensate. 550W worked in 2008 models but not for 2022 systems. This isn't the cheapest route. Reduce rainbow lighting, premium cases, and NVMe drives to stay within budget. A 2TB SATA3 SSD costs around $150. If you can't buy a Samsung Evo 870, opt for a WD/Sandisk Ultra 2 offering similar performance. For CPUs with 65W–90W TDP, a 75CFM+ heatsink plus fan from brands like Cooler Master, DeepCool or Corsair single-fan liquid cooling will suffice.
TDP and CFM aren't the best indicators to focus on. It's better to define the specific coolers you're considering. I wouldn't suggest relying solely on 120/140mm AIO unless room is limited. Cooler options in the same price range usually work better. The same goes for choosing brands randomly—consistency matters. Or are you comparing the CM Hyper TX3 and H80i as equivalent?
