Two Versions of Lenovo 45N0058 AC Adapter

I just got myself a brand new Lenovo Y50-70. It's a pretty awesome gaming laptop, because it has an Intel i7-4710HQ processor, a 4 GB GTX 860M graphics card, and 16 GB of RAM. Now it's time for me to purchase extra power supplies for convenience--one in the bag, one for my desk, and one in my office.

Being a gaming notebook computer, it's power supply is pretty hefty. Unlike other notebook AC adapters, the Lenovo 45N0058 power supply has a rectangular tip, rather than a round tip. The AC adapter's specs are:

Input: 100-240V 2A 50-60Hz
Output: 20V 6.75A 135W Positive Tip

Searching for the "45N0058" model number yields tons results. In fact, Amazon shows that this power supply is as low as $17.99 + $5.99 shipping. The problem is that every photo shows a round tip (see photo below). Examining the photo, you will see that the specs are identical, but the actual model number of that third-party power supply is "45N0059". Almost every Amazon page for that power supply claims compatibility with the "45N0058". See here:

Lenovo 36200605 45N0052 45N0053 45N0054 45N0055 45N0056 45N0057 45N0058 AC Adapter - Premium Superb Choice® 135W Laptop AC Adapter Battery Charger

I managed to find several Lenovo rectangular tip adapters. Just not sure which one is compatible with the power supply and the laptop.

Not sure if I want to take the gamble with this power supply and a tip adapter yet. Anyone found a good Lenovo Y50 power adapter substitute?

After doing some more digging, I found that the 45N0059's "Plug Tip Size" is 7.9mm x 5.5mm. So it seems like the right tip adapter is this one:

Shintop Lenovo Tip Adapter Connector Converter From Lenovo Ideapad/Essential to Lenovo Ideapad Yoga 11, 11s, 13, 2 Pro, Flex 14, 15 ; Lenovo ThinkPad Helix, x240, Carbon X1 ; Compatible P/N 0B46994, 0C19868, 0B47046, 0B47048 Ultrabook Laptop for AC Power Cord Barrel Adaptar Cable(Black)
