Dynex 400-Watt ATX PSU
Hardware Secrets have posted their review of the Dynex 400-Watt ATX PSU “In the old days, low-end Chinese manufacturers had only one power supply model with labels that could be fabricated according to what distributors buying from them wanted to be printed. This kind of power supply is still around – they are the so-called “generic” power supplies, but consumers became aware of this problem and started to demand products with labels that correctly described their current and power limits.
But it seems that Huntkey is still doing that. Dynex 400 W, which is a Huntkey Green Star 400 W, is identical to Huntkey Green Star 450 W: the exact same power supply, different labels describing the maximum currents and power the unit can handle.
This discovery explained why we exploded two Green Star 450 W units when trying to pull 450 W from them: internally they are a Green Star 400 W power supply with a different label. We are now curious to see the internals from other power supplies from the Green Star series like the 350 W and 550 W models to see if they are identical to the 400 W and 450 W models or if the manufacturer upgraded the components according to reflect the new power capacity.
Speaking specifically about Dynex 400 W, the main problem with this power supply is its price. Costing USD 80 it is simply too expensive for a 400 W power supply with low efficiency when delivering between 80% and 100% of its load and with a very high electrical noise level if compared to other good power supplies – even though it was able to deliver its labeled power at 50º C. Not to mention the ridiculous 1-year warranty – all other power supply manufacturers give a warranty of at least three years.”

Enermax Modu82+ 625W
PC Perspective has posted their review of the Enermax Modu82+ 625W “The new Modu82+ 625W power supply from Enermax delivered very good voltage regulation with clean outputs and excellent efficiency. On top of that, the Modu82+ 625W proved to be the quietest PC power supply we have tested to date in this power range. Throw in support for dual high-end graphic adapters, a compact chassis that will fit in most any ATX style case, and plenty of peripheral connectors and you have a very attractive PSU package! Note: If you prefer a PSU without modular cables, Enermax offers essentially the same units with fixed cables in the Pro82+ series. These new power supplies from Enermax should be of particular interest to anyone building a HTPC or silent PC.
My only complaint with the Modu82+ 625W power supply is the limited 3-year warranty, which seems a little out dated when many other high-quality power supplies are now offering 5-year, 7-year, or lifetime warranties.”

FSP Blue Storm II 500 Watt
Hardware Logic has posted their review of the FSP 500 Watt Blue Storm II “If you are looking for a PSU to replace one in a modest build, and do it with some style, the FSP Blue Storm II might just fit the ticket. It’s a good PSU with excellent voltage regulation under proportional loads. The matte blue finish is both subtle and obvious at the same time. The fully sleeved cable harnesses along with the included reusable Velcro straps are a plus for cable management and cooling. The unit should operate quietly under most conditions and runs rather cool as well. The efficiency of the unit is within spec at about 80%. The Blue Storm II is an example of a real ATX v2.2 500 watt PSU right down to the dimensions. And that means you won’t have to worry about it fitting in your case or actually putting out 500 watts when required!”
