Antec TruePower Quattro 850 W is a though competition to Cooler Master Real Power Pro 850 W. They are both could really deliver 850 W at 50º C during our tests, both can be found at the same price range and both are manufactured by the same company (Enhance Electronics) – using completely different designs, though.

Both achieved a very good efficiency, with the reviewed model from Antec achieving above 85% when we pulled up to 80% of the power supply capacity. When we pulled the full 850 W efficiency was still above 82%.

The only problem with Antec TruePower Quattro 850 W was that voltages weren’t “clean” when delivering 850 W at 50º C: noise level was above the maximum admissible. That was the only problem we had with this unit. With temperature below that noise level was just fine.

Since we hadn’t this problem with Cooler Master Real Power Pro 850 W and also we could pull up to 1,000 W with this unit from Cooler Master at 50º C with noise level below the maximum admissible (what we couldn’t with TruePower Quattro 850 W), we are more inclined to recommend this model from Cooler Master over the reviewed Antec product.

On the other hand this model from Antec brings a modular cabling system, feature not present on this model from Cooler Master.

Both models have over temperature protection (OTP), a not so common feature, but they both don’t have over power protection (OPP), which is a shame for models on this power and price ranges.

If you aren’t going to pull nowhere near 850 W – which is the case for 99.99% of users buying this power supply – this is a good buy and the problem we had during our tests won’t affect you.

But carefully research before buying, as prices change a lot depending on the store. The right price for TruePower Quattro 850 W is below USD 200, but we’ve seen some stores selling it by USD 250.
