The connections are already really spacious enough:
20 + 4 ATX board power supply
4 x SATA
2 x 4 pin molex
1 x P4
1 x Floppy
Not even a 6-pin graphics card connector is available, but you can get help with adapters.
Therefore I use for new computer as the better power supply
LC-Power LC5550-V2-2 with 550W
Sure, it costs twice, but has many more connections, is much more robust and easy-quality than the 420 W, about which I am writing here.
In addition, the current levels are higher, which also permits the use in high-quality PCs.
Conclusion:
To replace defective power supplies of old PCs this 420 W power supply is sufficient. Also very convenient for office PCs that are not otherwise provided along with high quality hardware, this cheap variant is easily sufficient.
