Conclusion

The 1STPLAYER SFX 750W Platinum is the first 1STPLAYER power supply we have seen here at The FPS Review. Making things a bit more challenging today is the fact that this unit is a teeny tiny SFX power supply and 1STPLAYER is a complete wildcard as a brand in the NA market. They do, however, exist as the brand name for the OEM Helly which did a good job when Lian Li was watching over their production of units for them. So, while PSUs from 1STPLAYER as a brand are unknown, we have seen some good results from this platform before. However, the devil is often in the details. So, is this unit truly the 1STPLAYER or is it the 1STDeadPLAYER? Let’s see.

Build Quality

Today’s 1STPLAYER SFX 750W Platinum starts things off with a build quality that is very much like when you see what looks like a Rolex, but then when you look a little closer you realize “no, no, that is not a real Rolex”. See, while this unit shares a platform with the Lian Li SP750 that unit looked every bit the part of a good power supply. The 1STPLAYER version though just is a little off in places. The branding is weird, the finish on the unit is bizarre and kind of sticky, and someone slapped an 80mm fan in a 92mm fan cutout. It just screams “something is off here”.

We also see FlexForce cables and standard sleeved cables. The integration is still clean, as with the Lian Li version. Also, much like that version, the component selection includes Nippon Chemi-con standard electrolytics and unknown solid electrolytics. Changing things up a bit, we get a sleeve bearing fan that is not only smaller than the fan found in the Lian Li version but also lower quality. Oh, joy. The documentation with this unit is terrible but the warranty is 7 years.

Load Testing

Today’s 1STPLAYER SFX 750W Platinum started off testing looking like it was going to do very well. Then it died. So, there is that to take into consideration. Now, for the tests, it did complete we saw voltage regulation of up to 0.04v on the 12v rail, 0.04v on the 5v rail, and 0.05v on the 3.3v rail. These values track very close to what we saw from the Lian Li Sp750 for the tests it completed. In addition to that, we saw efficiency that ranged from 88.86% to 90.57% efficient at 120v AC input and 88.43% to 89.90% efficient at 100v AC input. The unit also posted temperatures that peaked at 55C at 120v, 58C at 100v, and 67C in the Torture Test. Unfortunately, that is the end of the load testing data today since the unit was not able to complete any other tests.

DC Output Quality

The DC Output Quality results for the 1STPLAYER SFX 750W Platinum were very good for the tests it could complete. We saw peak ripple/noise values of just ~30mV of ripple/noise on the 12v rail, ~10mV on the 5v rail, and ~10mV on the 3.3v rail. These values don’t mean a whole lot though since they are not including the full load tests.

Noise

Today’s 1STPLAYER SFX 750W Platinum was quiet like a cemetery, on account of the fact that it was dead. Ok, so when it wasn’t dead the fan did not come on during the 25% load test so it was silent then as well. When the fan did kick in it was not bad, honest. It is a sleeve bearing fan though and the unit was getting kind of toasty though so I am not sure how long that recipe is going to last. 1STPLAYER seems to think 7 years. I think that may be a bit optimistic.

Overall, the low(ish) noise profile is largely artificial since we did not get the unit up to full load and complete testing. So, I can’t say it is truly a quiet option, but it is a silent one in about half of our tests (ok, technically 25% because it was dead in the 25%).

Final Points

The 1STPLAYER SFX 750W Platinum somehow took a platform that Lian Li did very well with and totally screwed the pooch. Worse yet, it is THEIR platform. Beyond that, the 1STPLAYER SFX 750W Platinum retails for $139 from their shop. But, if you want this particular platform, the Lian Li Sp750 for the same price this retails for, ~$139.99 is generally the better buy. At the end of the day, there is no reason to buy this unit with the other options that are on the market.
