GlacialPower is not one of the biggest players in the power supply market, and so we have one big question: do they manufacture decent products or are they just another manufacturer you should avoid? Today we are going to make a complete test on their latest 650 W model, GP-AL650AA, to see if it can really deliver 650 W, the quality of its outputs and its efficiency. Check it out.

GP-AL650AA has a very simple looks, being only 5 1/2” (14 cm) deep, as you can see on Figures 1 and 2. It features a 120-mm fan on its bottom, active PFC and no modular cabling system. No special attention was given to the aesthetic side, as only the main motherboard cable has a nylon sleeving coming from inside the unit.

This unit has an interesting feature: its fan keeps spinning after you turn the unit off, to cool it down.

The main motherboard cable uses a 20/24-pin connector and this unit comes with two ATX12V connectors that together form an EPS12V connector.

This power supply comes with six peripheral cables: Two cables with a 6/8-pin video card auxiliary power connector each,  two cables with six SATA power plugs each, one cable with three standard peripheral power plugs and one cable with three standard peripheral power plugs and one floppy disk drive power plug.

We think the number of connectors is satisfactory for the average user.

All wires are 18 AWG, which is the correct gauge to be used nowadays.

This power supply is manufactured by CWT with a design created by GlacialPower.

Let’s now take an in-depth look inside this power supply.
