1200 Power Supplies
BFG Tech LS 1000 and LS 1200 Power SuppliesBFG Technologies has recently gotten into the business of fully built computers called Phobos. While most of our readers may not want a computer built for them, you certainly want high quality components when you do build one. BFG Tech has recently started selling the 1kw and 1.2kw OEM computer power supplies previously reserved for Phobos owners only.
As we already know the BFG LS Series feature a single 135mm fan design that is used in the same vein as 120mm fans in that they can provide for quiet cooling environments due to the ability to move a larger volume of air at slower speeds than a smaller diameter fan. The 135mm fan is just short of the largest diameter fan we are likely to see in ATX power supplies given the physical constraints of the form factor. While great for quiet computing environments the key criteria in our evaluation is whether or not the cooling solution is sufficient, not necessarily it sound output level or form factor, although we certainly listen for offending units.
Externally both members of the LS family from the Phobos systems are identical except for the number of connectors. Both units come in a polished black finish that is smooth and lacks the embossed BFG logo that is found on most other BFG units (likely because these are OEM units). The top of the unit is dominated by the 135mm fan but again lacks the BFG logo while the rear features just the AC receptacle (absent is the on/off rocker switch). Both the LS 1000 and LS 1200 are 7 inches long and the cables reach out to 25 inches at the first or only connector with the sleeving being complete and well done on all of cables.
Looking at the LS 1000 from the top we see that this unit is the s ugg ame as the Enhance unit used in the Cooler Master Real Power Pro 1000W. Once more we see the BFG LS 1000 utilizing that same dual 12v transformer desig ugg n, same over all layout , and the component selections we can see from here are also identical to that previous Enhance unit. The heasinks once more dominate this unit obscuring most components as they move heat into the air stream generated by the overhead 135mm fan that is provided by Young Lin Tech and is rated at 0.25A at 12v. Lastly, as we have said about each Enhance unit built on this platform before, the quality of the machine work on the heatsinks for this unit is superb.
As we move on to the primary side of the LS 1000 we that the unit features a pair of primary capacitors even though the unit is an APFC design, just like we saw previously with the Cooler Master Real Power Pro 1000W. We find this pair of capacitors tucked under the main primary heatsink are provided by Nippon Chemi Con. They are rated a ugg t 420v 270uF each which again mirrors the 1000W Real Power Pro. Lastly, the heatsinks here are layered once more with various primary side components (like the rectifying bridge) receiving their own heatsinks.
On the secondary side of the LS 1000 we see that, like the Real Power Pro 1000W, the capacitors are an all Teapo affair. While also looking at the secondary side perspective we can see the small PCB that houses the majority of the input filtering components right above the AC receptacle, that when coupled with the few remaining components on the PCB, make the input filtering stage properly filled out. Moving on, the wiring for the unit dominates the majority of the frame and it is all bundled well with a few cables being sleeved all the way into the housing. However, the majority are not sleeved into the housing and there is no wire guard in place. Lastly, the fan controller and all the output protection circuitry is housed here on the main PCB right at the base of the input filtering.
Looking at the LS 1200 from the top we see that this unit is the same as the Enhance unit used in the Cooler Master Real Power Pro 1250W. The BFG LS 1200 continues to utilize the dual 12v transformer design that we saw in the Real Power Pro 1250W. The component selections we can see from here are identical to that previous Enhance unit and it is laid out like the Real Power Pro 1250W as well. The heatsinks dominate this unit obscuring most components as they move heat into the air stream generated by the overhead 135mm fan that is provided by Young Lin Tech and is rated at 0.3A at 12v. Lastly, as we have said about each Enhance unit built on this platform before (including the LS 1000), the quality of the machine work on the heatsinks for this unit is superb.
Over on the primary side we that the unit features a pair of primary capacitors even though the unit is an APFC design. This pair of capacitors are provided by Nippon Chemi Con and are rated at 400v 390uF each. Interestingly, due to these capacitors height the primary heatsink has been cut to allow these capacitors to fit unlike the ones on the LS 1000. We also see the layering of heatsinks on the primary side once more as various primary side components (like the rectifying bridge) receiving their own heatsink which is good.
On the secondary side we see the LS 1200 differs from the Real Power Pro 1250W some as the veritable grab bag of capacitors (Teapo, Su and “MC”) are replaced here with all Teapo This would certainly be a bit of an upgrade as Su is bottom of the barrel and “MC” was a complete unknown. Moving on, we can see the small PCB that houses the majority of the input filtering components right above the AC receptacle which differs slightly from the LS 1000 with the addition of another X capacitor. Finally, we see the wirin ugg g is all bound up and routed out of the unit without a wireguard. However, some of the sleeving does come back into the housing, just not all of it.
The overall build quality of both the LS 1000 and LS 1200 was very good, just like the corresponding Cooler Master units we have reviewed before. Externally, both units come in a very basic glossy black finish that lacks the BFG branding found on BFG retail offerings. The cables are sleeved back to the housing in a black mesh but only some are sleeved into the housing itself. On interior of both units, the primary side features Nippon Chemi Con capacitors of varying size, neat construction, and the bridge rectifiers both have their own heatsinks. The dual transformer design is once more present and is responsible for providing the 6 virtual 12v rails on the secondary side. On the secondary we find that both the LS 1000 and the LS 1200 feature Teapo capacitors. This change up on the LS 1200 over the virtual grab bag of less desirable capacitors we found in the Real Power Pro1250W is definitely a good improvement. Lastly, the machining on the heatsinks is once more top notch and really adds to the overall fit and finish of the unit. Let move on now and see if this kind of attention to detail carries on to other aspects of the unit in our performance testing.
