Mushkin Enhanced Joule 800W PSU


Many people think that the best processor, or the best motherboard is what lies at the heart of a custom built PC. The truth of the matter is, without the right Power Supply, it really doesn't matter what else you put in that dream rig of yours. An...

Small size - will fit in almost any PC ; Stable power output even under extreme stress ; 6+2 style PCIe power connectors provide VGA flexibility without needing adapters ; Simple, all-black, understated paintjob

Fan becomes audible (and noticable) under stress

I have almost nothing but positive things to say about this PSU. It does exactly what it says on the tin (or in this case, the cardboard box) and does so stably and quietly. Only pushing the PSU to it's limits starts to make it a little on the noisy...

Topower PowerBird 800W Power Supply


Not too big, not too small, just right. Topower attempts to master the 800 watt range in computer power supplies which while becoming more of a standard wattage in the industry, is not always easy to do well. Will it nest in your next chassis or flip...

The Topower PowerBird series first impressed us back in October of last year and today the 800W member of the PowerBird family delivered for us in almost every way we could ask of it. The 800W PowerBird had excellent voltage regulation on the minor...

The NZXT Performance Power 800W is a power supply that delivers good features and solid performance when heavily loaded with a case full of power-hungry components. From a feature standpoint, the unit supports SLI/CrossFire setups, and it's housed...

OCZ EliteXStream 800W PSU


OCZ's new EliteXStream packs quite a punch, especially for such an affordable price point. Finished in matte black, black sleeving, and a whisper silent 120mm fan, today's power supply is truly worthy of the elites.

Excellent performance ; Quiet ; Partially sleeved ; 5 year warranty

Disadvantages ; Not fully sleeved

OCZ's EliteXStream 800W is an all-around solid unit. The unit handled our tests without a sweat and held stable even in the harshest environment. As we have seen today, its performance is on par with much more expensive units.

OCZ EliteXStream 800W


Well guys, here we go again -- another close-look-at-power-supply-hardware report. Last week, we took apart the Seasonic M12II 500W power supply. As usual, because we don't have the necessary professional equipment to do the simulated load testing,...

Ultra X3 800w PSU


When you're running a high end gaming rig, having more power is a key issue. On top of that you need your power source to be reliable and stable. This is why today I'm happy to be reviewing the Ultra X3 800w PSU.

Ultra X3 800w Modular PSU


It was the Ultra X-Connect PSU that really brought modular cables into their own a couple of years ago. Since then, modular cables are almost a requisite component for a performance oriented power supply. There are a good number of other features that...

100% modular ; Shorter length unit than many other high end PSUs ; WIDE assortment of cable lengths and connectors ; Clean stable power delivery ; Silent 135mm cooling fan ; Flex force cable design ; Active PFC ; Lifetime warranty

No EZ-Grip connectors

As we have stated in the past, we wished we had a system worthy of pulling some major watts. Unfortunately an Intel Core2Quad with Quad SLI isn't in our financial future but a realistic rig that the average Joe Reader out there has is. Both the 800 and...

Kingwin 800w Mach 1 Modular PSU


Power requirements for modern high end video cards have skyrocketed in the past year. NVidia's GeForce 8800 series started this trend with the Radeon HD 2900 XT taking it trend a step further. For an end user to run a system in SLI or CrossFire, this...

Rock solid power delivery ; Quiet operation ; 800 watts at a reasonable price ; Modular cables ; Two 8 pin PCI-E plugs (on separate rails) ; Quad 12 volt rails ; Aircraft style cable connectors ; EZ-Grip Molex connectors ; Variety of cable lengths ;...


Throughout testing, regardless of power load or the case's ambient temperature, the Kingwin 800 watt Mach 1 was spot on showing less than 1% deviation from spec on each rail. Aside from clean stable power, which is the core issue of any power supply,...

AeroCool Strike-X 800W PSU Review


Today we are looking at a power supply from Aerocool, the Strike X 800W. This power supply is a modular design with 80 Plus Silver Certification. The appearance is certainly bold and dramatic but with such intensive competition today in the sub £100...

Looks quite attractive, if you like bold and loud design.

Corsair Gaming Series GS800 800W Power Supply review


Today we are looking at the latest power supply from Corsair, the Gaming Series GS800 – an 800W unit firmly targeting the mainstream enthusiast audience. This 80Plus Bronze Certified unit is a non modular design with a single +12V rail, supported by a...

A lot of work has went into the appearance ; Lighting switch ; Technically it is a sound design ; Quiet until around 700W of power output ; Decent noise suppression ; Efficiency is good for 80 Plus Bronze

Non modular

Kitguru says: A good purchasing decision if you want to focus on the appearance of your system. Technically it is a stable, reliable design at a good price.
