Made by popular graphics card company BFG, the MX550 might provide some modular competition to the OCZ ModXStream Pro, Corsair VX550W and HX520W power supplies. We dive in to find out if it's any good.

Enermax's premium PSU, the Revolution, claims 85+ percent efficiency. With an enthusiastic and unique design, housing DC-DC innards, Enermax has designed something quite special.

We constantly recommend the 650W Be Quiet! Dark Power Pro, but does the 850W afford the same awesome efficiency and virtual silence? With the same style of modular cables, shiny box, and a very similar build it be just as good or it might suffer from being just too hot.

In-Win sent us its camo styled, CWT built modular PSU and it certainly does quite a bit to differentiate itself in the market. We tested all 750 watts of the Commander to see if In-Win is worthy of your consideration in the PSU realm.

If you like a bit of bling in your case and don't care for extreme wattages, Hipers Type R II with its shiny blue casing, LEDs and metallic fan could be right up your street. We test this feature filled mainstream performer to see if it's cheap for a reason, or just fantastic value for money.

Antec's Signature is its definitive power supply, built on a idea of quality it's not cheap but it sports an 80 Plus Bronze efficiency, a semi-modular design and "hand certification." Are these the ingredients required to earn the bit-tech stamp of approval?

Corsair HX series has been a staple diet of many for a few years now, and finally those wanting a super-high wattage, Corsair quality modular power supply might be in for a treat with its HX1000. We put it on the testing block to squeeze it to its limits and beyond to see if it survives!
