Tuniq Potency 750 W Power Supply Review

Conclusions

Tuniq Potency 750 W comes to compete with other cost-effective 750 W power supplies like Seventeam ST-750P-AF and SilverStone Element ST75EF. This model from Tuniq offers as big advantage costing less than its main competitors: USD 100 against USD 110 (Seventeam ST-750P-AF) or USD 130 (SilverStone Element ST75EF). After a mail-in rebate offered at Newegg.com it will cost you only USD 70, which is an unbelievable price for a 750 W power supply that can really deliver its labeled power at high temperatures (in fact we could pull up to 937 W from it).

Seventeam ST-750P-AF and SilverStone Element ST75EF offer an efficiency that is little bit higher. In fact, if we were the ones behind the 80 Plus certification we wouldn’t give it the Bronze seal, since at
high temperatures this unit can’t deliver a minimum of 82% efficiency at light (20%, i.e., 150 W) and full (750 W) loads. Interesting enough the manufacturer knows that, since it publishes efficiency as “Up to 80%” (unless this is a translation error from Chinese to English).

On the other hand, this unit presents an outstanding voltage regulation (3% tolerance instead of the standard 5%) and low noise and ripple levels, being better than its competitors on these two aspects.

For its price, Tuniq Potency 750 W is an excellent unit. Of course there are better 750 W power supplies on the market, but they will cost you way more.
