That's what you get if you buy drives intended for backplane use.
Buy the ons intended for desktop cases, those with regular Molex power plug.

Have you ever seen the SATA drive with old-ATA-style 5pin large power
connector?

If yes - can you name the models? I have only seens the SATA drives with new
style power connector, looking like the SATA data one but wider.
