GPU upgrade ?
It all comes down to the PSU and the system in question. Being cautious is always preferable. PSUs tend to degrade over time, losing their full power capacity after several years. It's wise to choose models with 7 to 12-year warranties, though 10 years is quite typical.
A 300W GPU running on a 750W PSU works fine if the unit is good quality. Normal CPU usage during gaming stays under 100W, and the rest of a basic gaming rig fits comfortably within the limits.
Another reason to go oversized is uncertainty about what devices are connected to the computer. Some users even use them to charge their phones.
As for advice, could you clarify the region and currency?
I agree with you. In a perfect scenario, the TGP of a GPU would be straightforward to understand and include in buying decisions. Let's simplify things for everyone. However, reality isn't always that simple. High-end GPUs often show extreme spikes, while mid-range models tend to be more stable. This is something consumers should keep in mind, though few are aware of it.
Mainly because of the ATX 3.0/3.1 standards. They manage sudden power increases up to 100ms. However, PSU manufacturers often don’t adhere strictly to these requirements. Older models from the 2.x series still perform adequately during spikes.
For Seasonic, a notable issue arose with one of their popular high-end units when used with the 3080/3090. This wasn’t an isolated problem.
Mid-range cards previously required around 150W, but now mid-tier units typically need 200-300W. Smaller PSUs capable of this power are now less common and often of lower quality than expected.
What power rating should I select for the PSU? And is the extra $100 for a 9070 model justified?
When choosing a power supply, ensure it meets at least 650 watts for models like the RTX 5070 or RX 9070 non XT, including a 10-year warranty. For higher-end options such as the RTX 5070 Ti/4080 or RX 9070 XT, aim for a minimum of 750 watts. The RX 9070 non XT offers performance comparable to the 5070 but with slower ray tracing. Unless you play many competitive shooters where graphics settings are frequently lowered, this difference won’t significantly impact your experience. In single-player titles, the added VRAM can extend session times or enable higher textures and assets without sacrificing performance at resolutions of 1440p or above. The main factor in deciding between these cards is whether you prioritize DLSS 4 support or are willing to wait for FSR 4 compatibility in games you already own.
