Question What PSU for retro computer on 775Dual-880Pro motherboard?

[The Great Sephiroth]

I am planning to build retro PC dual boot 98/XP on 775Dual-880Pro Asrock motherboard with Intel Pentium D 945 3.4GHz and 2 x 1GB DDR2 667MHz and GeForce 7950 GX2 or GeForce 8800 GTX/Ultra on PCI-E slot and another GPU on AGP slot (anything in the range GeForce4 Ti - 7950 GT), sound card on PCI slot, optical drive and floppy drive, probably 3 x 2.5 inch drives (1 2.5 inch SATA SSD connected to IDE using SATA to IDE adapter, 2 2.5 inch HDD IDE interface drives) and 2 x 3.5 inch HDD drives, maybe some card reader and maybe something on PCI in the future. What would be good PSU for this that has all the needed connectors and enough amps on all 3.3V, 5V and 12V lines? I have poor knowledge in this topic. Would Chieftec GPS-450AA-101A be good and have enough power? But even if it would be OK, is it wise getting this used PSU? Are used PSUs good idea? If not, are there any of new PSUs that would be good for this specific retro build? Would any of SilverStone Strider series PSUs be good for this specific retro build? If the mentioned 2 are bad, what PSU would you recommend for this specific retro build?

IMHO you can pick up any off the shelf aftermarket PSU that has a 20+4pin ATX connector but please don't invest in units that are badly built. Only means your innards will be taken out when the unit goes out.

But even if it would be OK, is it wise getting this used PSU? Are used PSUs good idea?
An used PSU will not output the same amount of power it did when brand new. You also can't tell what the PSU was subjected to prior to your purchase.
