When we buy new PSUs for ourselves here at HardOCP, a company that always makes our short list is Enermax. Its build quality and performance has been topnotch for years. Today we put its 1.25 kilowatt computer power supply to the test. Crash and burn or continue to shine brightly?

DC-DC converters, independent stabilization, synchronous transformers and synchronous rectifiers, over 90% efficiency factor - please meet new high-end power supplies: Antec Signature, Enermax Revolution 85+ and Seasonic M12D.

Another entry into the 850 watt enthusiast desktop computer power supply market place, this time from a front runner the PSU business. If this unit is even up the heritage that we saw from the 1200 watt Toughpower a couple of years ago, it will still be a good unit. But is it a great PSU?

Enermax is a name that carries a lot of weight with enthusiasts and the company is stepping out with a new mid-wattage PSU that delivers 625 watts plus a whole lot of marketing claims. But what about good clean power&#63 We find out.

Best Buy has certainly stepped up its game in the last few years when it comes to better servicing the DIY computer builder or upgrader. But is Best Buy doing you a service a disservice by selling you its own computer power supply&#63

We have seen Xigamtek shine and fail when it comes to building computer power supplies. How does the company do today with a $110 (after $20 MIR) 750 watt power supply? Once again we get to see if “No Rules Power” violates ATX rules.

Another contestant in the 850 watt computer power supply market moves into position. Does this long respected chassis manufacturer have what is needed to give us an award winning PSU that is a good value? Just passing our test suite is a tall order; attention private!

If a company is ballsy enough to send a 1 kilowatt + computer power supply into HardOCP it must be just that good. Or is it? We show you again the reason for knowing what you are buying when it comes to PSUs.

BFG has recently proven its worthiness in the high end computer power supply market by providing extremely stable and innovative products. Can BFG pull off another win as it wades again into the middle of the wattage war with many competitors?

No Rules Power! That makes for a good product tag line, but we all know damn well that power without rules makes for a terrible computer power supply. Does Xigmatek's NRP 850 watt PSU play inside the rules when it comes to serving up 850 watt?
