Windows 7: What to do with an older PSU?

17 Sep 2011   #1

What to do with an older PSU?

I have an Thermaltake Purepower 430 NP PSU .. but it has a fairly low +12v and high +3.3v & +5v

+3.3v - 28A
+5v - 30A
+12v - 18A

Would this be more suitable for a server box or summat?


edit: as I was typing this post, I searched around for reviews & tests. This was/is a cheep PSU, a mixture of ATX12V 1.x specs with 24pin MB connector, SATA & PCIe connections, no active PFC and efficiency maxed at ~70%

I think I'll look for my local computer recycler depot and drop it off

Also .. could I use a newer 24pin MB PSU on an older P4 20pin MB? The newer PSUs MB connector is 24pin .. not 20+4pin.

Yep. The +4pin is detachable.

Yep it works .. the 4 pins are kinda hanging over the edge .. but it works! My parents Dell PSU's fan was starting to WRRRR, and I had a OEM Asus 300w PSU laying around.

Old power supplies make good door stops. They aren't heavy enough to use as boat anchors.
