Silver Power SP-S850M review
For an 850W PSU with modular cables, the Silver Power SP-S850M has a great price and is one of the cheapest high-rated supplies that we've tested. For anyone looking to build a powerful system on a tight budget, it's definitely an interesting choice.
It has 80 Plus Bronze certification, which guarantees efficiency of at least 81 per cent at all loads. In our tests, the power supply performed much better than this. It managed 84.87 per cent efficiency at 100 per cent load, 87.41 per cent at 50 per cent load and 85.85 per cent at 20 per cent load. That's impressive efficiency from a Bronze power supply.
This power supply exceeds the 80 Plus Bronze standard
Although it's just 160mm deep, the SP-S850M has a decent range of connectors. It's a modular supply, bar the motherboard, CPU and two 6+2-pin PCI Express connectors, so your case won't be cluttered with unnecessary cables. Using the modular cables you can connect two 6+2-pin PCI Express, eight SATA and five Molex. That's enough for a high-end build with dual graphics cards.
It's not all brilliant news and the 120mm cooling fan is very loud. In fact, at high loads, this power supply was incredibly loud and soon drowned out the other components inside the case. This is rather distracting and we'd prefer to have a quieter power supply.
In terms and efficiency, price and features, the Silver Power SP-S850M is a great supply, but given how loud it is, the XFX Pro 850W XXX Edition is a much better buy.
