## Questions & Answers

**Q: Can someone tell me what is the point of a fully modular vs semi mod power supply. Aren't you always going to use the 24pin and 4/8pin connections?**
A: Fully modular is all the cords can disconnect from the power supply so you only use the cords you need, semi modular has cord that do not come off, sometimes there are cords you don’t use and you will have to just tie them off.

Fully modular is better for keeping things neat, semi not so much. (Fully modular potential less dust because of less cords, maybe)

**Q: Is this works for the RTX 40 series ???**
A: This PSU doesn’t come with the 12pin cable to plug straight into 40 series, but will work if your GPu comes with the adapter

**Q: Is this a sfx psu ?**
A: It's an FX.

**Q: Does this have Atx 3.0?I don't see connection**
A: This is not ATX 3.0 compatible
