Thermaltake Toughpower iRGB Plus 850W Platinum (850W/80+ Platinum/ATX/Fully Modular/ATX 2.x) Review
If you're searching for the Thermaltake Toughpower iRGB Plus 850W Platinum, or just looking for a solid 850W 80 PLUS Platinum PSU in a ATX form factor, here's the full rundown on specs, price, and how it stacks up.
Short answer: the Toughpower iRGB Plus 850W Platinum is a fully modular 850W unit built to the ATX 2.x spec, and we'd recommend it if you want Platinum-tier efficiency at this wattage without chasing a flagship price tag.
Efficiency and Build Quality
The Toughpower iRGB Plus 850W Platinum carries an 80 PLUS Platinum certification, built on a Channel Well Technology platform. Its 140mm RGB fan, hydraulic bearing keeps noise down, with Zero-RPM fan-stop under light loads.
Connectors and Cabling
You get 1x 24-pin ATX, 1x EPS 4+4, 4x PCIe 6+2-pin, 8x SATA, 4x Molex. Cable lengths run 24-pin 600mm, EPS 650mm, PCIe 650mm, SATA 750mm, and the cables are sleeved. It's rated for a 17ms hold-up time and backed by OCP, OVP, OPP, SCP, OTP, UVP protection circuitry.
Comparison to Alternatives
Compared to the Thermaltake Toughpower PF3 850W, the Toughpower iRGB Plus 850W Platinum lands in the same efficiency tier at a different capacity, so the choice mostly comes down to how much wattage headroom you actually need. It's also worth cross-shopping against the Seasonic Vertex PX-1000 if you're weighing Platinum-tier options in this wattage class; both land in a similar price bracket, so the deciding factor usually comes down to form factor, cable sleeving, and warranty length.
