Obviously, that's even worse than "manufacturer refurbished", because at least those units normally get like a 1 year warranty, but the difference in price between that unit and other units that come with FULL warranty, like I said before, MORE than justifies the extra expense. You WILL kick yourself as hard as possible, right in the ass-tronimical area, if you buy a refurb unit and it fails two days after the warranty expires. Besides which, you wouldn't buy a used car without knowing how many miles it has on it, and there is no way to know that with a power supply, which makes it a very risky proposition. Especially when it's not a manufacturer refurb unit.Based on amazon link, it isn't manufacturer refurbished. Instead, it is:
For warranty period, it comes with 90 days.
For comparison, brand new RM650 comes with 10 years of warranty.
I wouldn't buy it.
