A: Yes should be. I use to run Minecraft and gta on a 500w

**Q: Can I use the same cables from the 2019 version**
A: According to corsair web page, both are compatible, with the type 4 cable set, so it should work, if using the UK version, others are probably the same, but only shows UK version. Best way to check is ask Corsair, to get a complete answer. I personally don't mix cables.
