Outdated Product
Inexpensive computer power supply of moderate power (450 W) with a basic set of non-removable cable lines and passive power factor correction. It is positioned as a product of the basic price category, designed to power multi-purpose home PCs and low-cost gaming systems equipped with video cards with typical power consumption up to 125 watts. Can successfully work in office workstations. The Gamemax GM-B Series GM-450B power supply is based on a reliable and time-tested hardware platform with traditional circuitry using the group voltage stabilization principle. The use of a high-quality element base and impressive aluminium radiators allow the device to deliver up to 64% of the power along the +12V line in continuous mode, working with a current load of up to 24 A (up to 28 A for a short...time). The device is cooled by a controlled 120 mm fan with a 7-blade wide impeller of a special profile, optimized for operation at low speeds. In addition to standard ATX 24-pin (20+4) and ATX12V 4-pin cables, it is equipped with a cable with a PCI-E 6-pin connector, a 2xSATA line and a 2xMOLEX (4-pin) line. The power cable is not included and must be purchased separately.

There will be no photos, I already have a new power supply unit and I sold it for spare parts for 1/3 vart

I bought it new, for 700 UAH at that time (2-3 years ago). Guys, I’m already fortunate that, having lived this long, it’s better to buy a normal type of clothes, some rotten junk (through which I fly), on my own less traction, otherwise I won’t live long.
The price at that time was too expensive
It's greedy, it's greedy
