Review Chieftec Nitro 88+ SPS-750C power source Thursday, 8 November 2012

This is lightweight* review for Chieftec Nitro 88+ SPS-750C, let’s say more suitable from a regular user point of view than for technician. So, we have in the light the PSU named SPS-750C, which is a power source of latest high-end series from Chieftec. As many knows, the company products are popular for their optimal price/performance ratio and Nitro 88+ SPS-750C PSU is not far from the true, if we don’t take into consideration the bright – red color (that striked me somehow). As stated, on power source segment, Chieftec managed to come with quality products at resonable prices, and this is a point taken.

Untill recently Chieftec got two lines in power sources high-end segment, Nitro 85+ (S/C) / Nitro 85+ II (C2) with following units:

  • 4 x standard units 80PLUS, bronze certified, 120mm, efficiency >85%, Active PFC, silver color and maximum load  from 350w to 500w
  • 5 x modular units 80PLUS, bronze certified, 140mm fan, efficiency >85%, Active PFC, cable management, black color and maximum load  from 550w to 850w, and 1200w,
  • 1 x modular unit 80PLUS silver certified, 140mm fan, efficiency >88%, Active PFC, cable management, black color and maximum load of 950w
  • 4 x modular units 80PLUS, bronze certified, 140mm fan, efficiency >85%, Active PFC, cable management, black color and maximum load  from 550w to 850w

Therefore was time to launch of a new line, the NITRO 88+ Series is now the new flagship of Chieftec’s power supply line with higher efficiency standards and affordable in the same time. The new line comes with four modular units 80PLUS, silver certified, 140mm fan, efficiency >88%, Active PFC, cable management, red color and maximum load  from 650w to 1000w. In this review we are about to lightweight* test the SPS-750C unit. The maxium load is 750W at >88% efficiency. All cables are modular, less the motherboard lines but this makes sense, the mainboard lines are always needed. The modular lines covers even the highest demands and the unit comes with:

  • 2 pcs – SATA cables with 4 connectors each
  • 4 pcs – PCI-E 6+2 pin cables with one connector each
  • 2 pcs – IDE 4 pin (molex) with 2 connectors each, on line has also the FDD 4 pin connector

Test system:

  • Intel Core i5-750 2.66GHz – OC@3.20GHz
    Asus P7P55D
    Corsair Vengeance v3.19 DDR3-1866 8GB
    Corsair CSSD-F120GB2 (1pcs)
    Western Digital WD3200AAKS (2pcs)
    Western Digital WD20EARX-00PASB0 (2pc)
    Gigabyte GeForce GTX 465
  • Windows 7 Ultimate x64 SP1
    CPU Caps Viewer v1.8.6
    TechPowerUp GPU-Z v0.6.6
    CPUID CPUz x64 1.61.3
    GIMPS Prime95 v26.6.build.3
    AIDA64 v2.70.2208

*lightweight TEST – that means we tested the power source unit using only software measurement tools, we didn’t dismantled the power source or measured the parameters with specific hardware equipment (oscilloscope, A/V-meter, specific test platform, etc).

 conclusion_wallet
  • the Chieftec PSU – Nitro 88+ SPS-750C can be found in stores (Europe) at the approximate price of 115 €
conclusion_hand_pro
  • optimal voltage stabilization even under heavy load, especially on 12v and 5v rails
  • good price/performance ratio
conclusion_hand_cons
  • some minor issues on voltage stabilization for 3.3V rail under heavy duty but only when video card is on full load
conclusion_pen Beside the red color the external look unveils neat manufacturing quality, i can say the best i’ve seen on a power source from Chieftec so far. I didn’t test the efficiency but i’m pretty sure that is not a problem, at least seen the results for voltage regulation that are excelent, i can safely presume that the efficiency is the same, maybe not for low loads, around 20% where all PSU got their issues but anyways must be better than average.
