BFG LS-450 Power Supply Review

Conclusions

We were very impressed with BFG’s LS-450. While the manufacturer cautiously announces efficiency as “80% minimum,” in fact LS-450 is a high-efficiency product, with efficiency ranging from 84.4% and 89.8% at 115 V. And, of course, it can deliver its labeled power and some more at 47° C.

LS-450 is a good competitor to the new Thermaltake Litepower 450 W, which is also a high-efficiency 450 W power supply. Thermaltake’s model has as advantage an even higher efficiency, while the advantage of BFG LS-450 is having longer cables, more SATA power connectors and a better price: USD 70 at Newegg.com, or only USD 45 after a mail-in rebate (on BFG’s website it is sold by USD 90, so avoid buying it there!). This put this power supply as one of the best cost/benefit ratios for the savvy user that is building an entry-level or mainstream PC and wants to save both on the cost of the power supply and on the electricity bill.
