High-value ASRock Z170 Extreme4 Motherboard Detailed
ASRock is seeking to strike a cost-features sweet-spot around the $130-150 mark with the new Z170 Extreme4 motherboard. ASRock didn't finalize the board's heatsink design, but showed it off at Computex. This ATX form-factor, socket LGA1151 motherboard based on Intel's Z170 Express chipset, features four DDR4 DIMM slots, supporting up to 64 GB of dual-channel DDR4-3400 MHz memory. A 10-phase VRM powers the CPU. The board draws power from a combination of 24-pin ATX and 8-pin EPS connectors; and with this generation, is appears that ASRock has finally got the onboard electrical distribution right; with the board lacking any additional power inputs.
Expansion slots include two PCI-Express 3.0 x16 (x16/NC or x8/x8), one PCI-Express x16 (electrical x4) wired to the PCH, and three PCIe 3.0 x1 slots. Much like the beefier Z170 Extreme7, this board offers three SATA-Express 16 Gb/s ports, but just one M.2 (32 Gb/s) slot; and six SATA 6 Gb/s ports. All other essentials for this generation are covered, with two USB 3.1 ports (one each of Type-C and Type-A), and eight USB 3.0 (four on the rear panel, four by headers); 115 dBA SNR onboard audio with a headphones amp and ground-layer isolation; and a single gigabit Ethernet interface (Intel controller).

The 24-Pin only has 2 wires for the +12v, it is only good for 75w. So if you have two cards, both drawing near 75w each, those two wires and the pins in the connectors get pretty toasty.
On May 2010, the only mentioned of "PS/2" on Logitech's website was this guy. It's a USB mouse with a PS/2 adapter.
On June 2005, it was still the same story. USB mice with PS/2 adapters, such as this white and grey beauty. On June 2003, wheels are all the rage, but even the First Wheel Mouse is USB with a PS/2 adapter.
Admittedly, it's not impossible to find discontinued PS/2-only mice for sale even today. The point is, USB has the de facto standard for at least 12 years.

I will just add that, back in 2000 (15 years ago), Microsoft and Intel published something called the "PC 2001 System Design Guide". In this guide, PS/2 was dropped and referred to as a "legacy" connection.
- Sometimes my USB keyboard doesn't work in BIOS/POST environment. At that time my old PS/2 keyboard is never fail.
- In theory, with shitload of USB peripherals working at the same time, it's possible to run out USB bandwith leading to irresponsive mouse/keyboard. I'm sure it'll be rare case though.
Besides, it's only a small cute pastel colored port. DVI/DSUB combo is far more annoying.
Oh, and about Logitech thingie. I'm pretty sure when I started my office back in 2009, we bought plenty of PS/2 only Logitech mouse. Not sure the model but it's pretty basic and it's black. I think different country has different products after all.
