Hello
- Processor: PIII-S: 1.266 GHz, SL5QL.
- Basic graphic card: GF4 MX440 or GF5 FX5600.
Will a basic 550W Seasonic 5V 20A or a Corsair, Be quiet! 5V 25A work fine ? No need for 5V 30A ?
- I also have this MSI K7N2 Delta-L (AMD Athlon motherboard)
So with this I need 5V 30A power supply I'm right ?
Old Durons work with 5V 20A and for larger Athlon XP: 2400-3200+ I need 5V 30A.
In a one very old project I used: 600 MHz Duron, Voodoo 3 AGP and BeQuiet! 5V 30A power supply just to be sure.
Confusing is 5V20A enough ?
New Seasonic's with 5V 30A are 1000W power supplies.
New Be Quiet! Dark Pro 11 and Straight Power 11 are with 5V 25A.
New Corsair RM--X and RM--I are with 5V 25A.
I believe PhilsComputerLab has already answered this on YouTube.
5V is mainly a concern for certain ISA cards and AMD Socket A CPUs. If it's a late-90s rig with late/no ISA cards, then any modern PSU is fine. In my Pentium III-S and 4 builds, I use budget modern Corsair PSUs, no issue.
Now, I do use a 5V-capable PSU from StarTech that you can buy brand-new in my Pentium MMX 233 system, just in case. (product page - https://www.startech.com/Computer-Parts/PSUs/ … ply~ATXPOWER300) Right now, due to the human malware situation, JayzTwoCents has noted that there appears to be a PSU shortage in the retail market, so finding one online new for a good price (my two units set me back $35) is going to be a bit challenging, but give it a few months and hopefully they'll be back in stock.
