Review Thermaltake Power Express 650 – Affordable Power for Your High-end Graphics

The Power Supply Unit or PSU for short is one of the most vital components in every desktop computer. It pumps electricity –the lifeblood of electronics- to every hardware so that they could function as intended. However, each PSU has a limited capacity or rated power, such as, say, 600 watt, which means that it could only supply that much power to the peripherals it’s connected to. This could become a problem when you want to add some extra components that would potentially increase the overall power consumption beyond your PSU’s rated power, such as the notoriously power-hungry, high-end graphics cards. Simply replacing your PSU with a beefier one would solve the problem, but that would cost you some good money since high-quality PSUs (especially those with a rated output of 1000 watt or more) usually come with eye-popping price tags.

Fortunately, there’s now a cheaper alternative to that. Instead of replacing the PSU, how about adding another one that supplies power exclusively to your graphics card (s)? Not only will it save you some money, it will also take a large part of load off your main PSU, enabling it to supply more power to other components like the CPU or motherboard. Meet the Thermaltake Power Express 650, a power supply that is specifically intended to power up your graphics subsystem. The best thing about this graphics-only PSU is that it only costs Rp 400 thousand or around US$ 45!

Like the name suggests, Thermaltake Power Express 650 has a rated output of 650 watt. Pretty high for a PSU that supplies power exclusively to graphics card (s). This PSU has a complete array of electrical protections, including Voltage Protection, Circuit Protection, Temperature Protection, and also Active PFC. Each of its two 12V+ rails is able to deliver 30 Ampere of current. That’s about enough to power up today’s high-end graphics card.
