In caz ca mai aveati dubii: Corsair VX450 disecata pe Hardware Secrets.
Un test de overload (adica un fel de overclock la surse )The results for this power supply were simply unbelievable, especially when we think that this is supposedly an entry-level power supply. After reviewing a lot of lousy low-end power supplies it is a real joy to see an entry-level model that can not only deliver its rated power at 48º C, but also achieve an outstanding efficiency and a very low ripple and noise levels.
Bottom linewe could make our 450 W power supply to work stable at 570 W at 48º C and with 81% efficiency! Holy cow!
Acu' sper ca ma intelegeti de ce (pentru un sistem normal single CPU/single GPU) recomand numa' VX450 si EarthWatts, in functie de buget.If we could summarize this power supply in just one word it would be “wow!”. Together with Antec EarthWatts 500 W this is the best power supply up to 500 W we have ever seen, bringing the best cost/benefit ratio for the average user building a mainstream PC with a good video card, graduating Summa Cum Laude in our tests. You will bring home a relatively inexpensive power supply that even though is sold as being a 450 W unit can deliver up to 570 W at 48º C – in fact Corsair could have easily labeled this power supply as a 500 W unit, but they preferred to stay on the safe side.
