Power supply B: SeaSonic SS-500ET 500W ATX12V V2.2 / EPS12V V2.91 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply - OEM 74.50 dollars
I did a bit of research and I found that the ATX12V V2.2 specification (power supply B) requires that power connectors that plug into the motherboard be of higher quality.
I couldn't find anything about ATX12V v2.31 (power supply A)
Which of those 2 power supplies is superior?
Here are my wild guesses:
I think power supply A (83 dollars) came from an earlier batch so the price is higher. Power supply B (74.50 dollars) came from a more recent patch after Seasonic found a way to reduce manufacturing costs (not by choosing lower quality parts I hope-again just wild speculation on my part).
Any info pertaining to the difference between those 2 power supplies would be appreciated.
Once I get this power supply I'll give my Antec Neopower 430 watts (32 amps on 12v rails or 384 watts on that 12v rail) to my brother.
He's running a GTS 250 that requires 2 pci-e power connectors on a Diablo 550w power supply (20 amps on 12v). This power supply has no pci-e connectors of its own, so we have to use one pci-e = 2X 4-pin adapters. Therefore we should need 4 x 4-pin power connectors to cover both pci-e power ports of the GTS 250.
However, the Diablo 550w only has 2 free 4-pin power connectors, so 1 x 4-pin power connector on the other side of each pci-e power port
