Seasonic and XFX manufacture most power supplies, while yes EVGA is reliable and I've used them many times: they don't actually manufacture their own and simply rebrand ones produced by Seasonic and XFX. The reason why I suggested Corsair is because all Corsair power supplies are rated for continuous and not just peak load. Yes, you are right about 80+ certificate not equating to reliability and just efficiency. However, manufacturers typically don't cheap out when it comes to mid to higher end products.I'd recommend that you buy a better PSU, thermaltake don't make good units, they only have some good ones, but yours isn't a quality one. I wouldn't risk to stress test my PC if the smell comes from the PSU. If the PSU is failing, it may damage something in your PC. Mention your budget for a PSU please.
