Older thermaltake power supply for modern usage.

post #1 of 3
Thread Starter 
Got this older 400 watt Thermaltake power supply from 2006. Was going to use it on a buddy's system build. The main connector has only a 20 pin rather than a 24 pin. Is there a way to make this power supply work? Maybe a 4 pin I'm missing somewhere or didn't see it?

2 things:
1.You can use a 20-to-24 pin adapter for the old PSU
2.Older PSUs might be pre-ATX2.0, likely your TT. This means it can output most of its 400W on the +5V and +3.3V rails the +12V rail doesn't get as high a % of the total power as in newer ATX 2.x PSUs. To cut it short you could say your PSU ATX 1.3 400W is somewhat equivalent with a ATX 2.3 300W on a modern rig (C2D, AM2 and later). Use the 400WPSU with an adapter only if the rig isn't very power hungry and can fit easily in some 250W (my sig rig never goes 320W for example so many configs can be powered with that PSU)
