This is a Thermaltake Toughpower Grand Series RGB 850W fully modular power supply. The unit was pulled from a working system and has been tested before shipment. It is in fully working condition and ready to install in your compatible build. Please note this PSU does not come with all cables — included cables are both motherboard cables (24-pin ATX and 8-pin EPS), one PCIe cable with dual 8-pin connectors, and one SATA cable. No other cables are included. This is a great budget option if you are looking for a high wattage modular PSU and already have compatible cables or plan to purchase them separately. I will only ship to the continental United States. You must enter a valid payment form and your current address. If you have any questions please let me know.
