Just be careful that the new PSU you source has adequate protective measures built in. Here's an FSP (Fortron) built unit still in retail channels which should work for everything up to a Barton 3200: http://www.sparklepower.com/pdf/FSP300-60PLN.pdf oh awesome this is perfect! you can even get it …

Iv don't doubt the old PSUs will work but I personally Id rather use a new one to totally avoid the risk of loosing components in the event the PSU dies. I'm paranoid 🤣, thanks for the successions anyways ^^

Yeah getting a 750w PSU for a 90s era PC is extreme, but looks like the most promising suggestion to me. Although... Pasing Post isn't much prove that your PSU isn't faulty

When I looked at it the first time I thought I saw the 24A as being on the 5v. Hm. Well fair chance it'll work but not as likely as the 5v having been 24A :( I mean 5v 20A is 100w on its own so with 110w 3.3+5v power that'd only leave about 3 amps for 3.3v while this will leave about 15A for 3.3v …

Ooh nice find that 750w evga PSU is the best so far way cheaper that anything I've found, and just to be sure the amps should be enough right ? (Sorry I really know nothing about PSUs 🤣) http://www.evga.com/products/product.aspx?pn=110-BQ-0750-V1

Mmmh I'm having no luck finding a new psu that isn't like 1000w+ with the ratings I need, what would you guys use to power a PC like mine?

I just had a look at the ratings for th PSU I was using the 3.3v and 5v combined watage is 220 that's total over kill right?

110 watts for those rails is low especially when you're doing something like V2SLI. I'd say you should get something where that rating is more like 150 watts or higher. You can easily find that rating being a bit higher on some supplies, like 130 watts on some models, but 20 more watts there is not …

I don't know if those converters excist. Yet since you got a P2B board, have you been into the BIOS in order to see, if you can disable power monitoring of -5v? On some SS7 boards, and in particulair the Asus P5A, you have that option. Both the P2B and the P5A are from around the same timeperiod. …

Which Corsair PSU is it and what are the ratings on the side? Especially the current rating for 5v (not negative 5, just regular 5v) as well as the combined power rating for the 3.3v+5v rails. A lot of newer PSUs have, say, only 16-18A on 5v, and very low combined 3.3v+5v ratings like say 80 watts …

The cpu I think but tbh I don't know It has a 2.0v slot 1 Pentium 3 600mhz, voodo2 sli, nvidia TNT, creative soundblaster live 5.1 and 256 mb ram on a Asus p2b I've tried starting it with a corsair 430w PSU I got past post but it would freeze loading win 98 :/ But I have no probs when using some no …

Thanks for the quick reply Unfortunately my PC is atx, I guess there isn't a 24 pin to 20 pin atx adapter with -5v generator?

Hey all I have a retro 90s PC that I want to run with a modern PSU to prevent losing components should the PSU fail however when I start the computer it gets past post and then freezes loading win 98 :/ But when using some old 20 pin no name brand PSU it works no problems Any idears on how to get to …
