650W PSU Planning for RTX 5090 Builds in SA
650W for RTX 5090 needs a full-build check, not a simple yes. Review GPU guidance, CPU draw, transient load, connectors, PSU quality, and upgrade plans before deciding.

PCIe 5.0 SSDs matter to SA PC builders mainly for future-proofing and heavy creative workloads, not gaming, where Gen 4 NVMe is still the value choice. Gen 5 drives hit around 12,000-14,000MB/s versus Gen 4's ~7,000MB/s, but games load barely faster because they are not bottlenecked by sequential speed. A Gen 5 drive also runs hot and costs far more. For most builders, a 2TB Gen 4 NVMe (around R2,000-R2,800 at Evetech) is the smarter buy.
What PCIe 5.0 Actually Delivers
Gen 5 NVMe roughly doubles Gen 4's sequential throughput, reaching 12,000-14,000MB/s. That sounds dramatic, but game load times depend more on random access and CPU decompression than raw sequential speed. In real testing, a Gen 5 drive loads games only a fraction of a second faster than Gen 4, a difference you will not notice in practice.
Where Gen 5 Is Worth It
If you move enormous files daily, video editing in 8K, large dataset work, or fast scratch storage for content creation, Gen 5's throughput saves real time. Builders planning a long-life rig may also want the standard on the board now. Outside those cases, the speed is academic for a gaming machine.
The Heat and Cost Reality
Gen 5 drives draw more power and run hot enough to need a chunky heatsink or active cooling, and they cost a clear premium over Gen 4. For a gaming or general build, a 2TB Gen 4 NVMe at around R2,000-R2,800 delivers ~7,000MB/s, runs cooler, and frees budget for a better GPU. That is why Gen 4 remains the SA value sweet spot.
FAQ
Is a PCIe 5.0 SSD worth it for gaming?
Not really. Games load only a fraction of a second faster than on Gen 4, because they are not limited by sequential speed. A Gen 4 NVMe at ~7,000MB/s is the value choice for gaming builds.
How fast is a Gen 5 SSD versus Gen 4?
Gen 5 reaches roughly 12,000-14,000MB/s against Gen 4's ~7,000MB/s. The throughput helps heavy file work but makes almost no difference to game load times in real use.
Do PCIe 5.0 SSDs need extra cooling?
Often, yes. They draw more power and run hotter, so they need a substantial heatsink or active cooling to avoid throttling. That is another reason Gen 4 stays popular for gaming rigs.
For a gaming build, fit a 2TB Gen 4 NVMe (~R2,000-R2,800) and put the Gen 5 premium toward your GPU. Choose Gen 5 only if you do heavy creative file work that needs the throughput.
