I recently made a number of upgrades to my PC including the video card, processor, and motherboard. About a year ago, I bought the Thermaltake SMART SP 650W 80+ Bronze PSU with my R9 270X. I have since upgraded to a Sapphire R9 290 Tri X OC and am starting to wonder if my brand of power supply is good for my system (I have heard Thermaltake is not a good quality brand like Seasonic, EVGA, Corsair, and XFX). My Specs: Processor- Intel Core i5 4690K @ 3.5GHz (usually sits at 3.8GHz/3.9GHz boost) CPU Cooler- Cooler Master Hyper T4 Motherboard- Gigabyte GA-Z97X-UD3-BK Video Card- Sapphire R9 290 Tri X OC @ Stock speeds Ram-16GB G.Skill Ripjaws Z @ 1600MHz Storage- 1TB WD Blue 7200RPM HDD PSU- Thermaltake SMART SP 650W Standard 80+ Bronze Case- Corsair Carbide SPEC 02 Extra case fans- 2x Corsair AF120 Performance edition (front intake and rear exhaust) and 2x Antec True Quiet 120mm (bottom intake and top exhaust). Most PSU calculators show that 650W is sufficient for a build like mine, but is my power supply a quality product or will I experience hardware failure due to cheap parts? If I do need to switch my power supply, what is a good choice?
