This review is from: XIGMATEK XCP-A500 500W ATX12V Ver2.3 Power Supply
Pros: This is a good little power supply for the price, but it's not a 500W power supply. OEM is Andyson. I opened it up (I know it voided the warranty but if it breaks I will fix it myself) and on the 12V, it only has a single 30A rectifier. No dual rails, but that's still 360W of power. Although I think this thing combined load could only handle 350W because the transformer isn't very big (ERL-35) and would probably saturate beyond that.
With how power efficient the new components are getting, this thing could still power a beefy gaming system. This thing could power an Ivy Bridge i5 with a GTX 670 with no issues
Very quiet thermally controlled fan. Efficiency is give or take 74-78% which isn't bad at all considering it doesn't have PFC.
Nicely sleeved, good packaging
Cons: Not 500W, not enough 12V filtering (Only one 3300uF cap) only 1 PCI-E 6+2 connector
Other Thoughts: This thing uses Sun primary caps, and the rest are Jun Fu and Teapo. While not the best choice of caps, they aren't exactly horrid either. I replaced them all with Panasonic and Chemi Con caps but it should still last a while with the stock caps.READ FULL REVIEW
Pros: The only pro is that you don't HAVE to buy it
Cons: Where to start...
- Loud fans
- 4 diodes instead of a bridge
- Cheap BH 85C rated capacitors
- Undersized Fuhjyyu input capacitors
- No input filtering
- Horrible efficiency
- Can't do half its rated wattage
- I looked at the 12V rectifier and it's actually 20A, not 25A
- Tiny heatsinks
- No thermal protections (Usually results in a boom and dead components)
Other Thoughts: Avoid any PSU under $35. You get what you pay for! Think about it. They have to make money off this and so does Newegg. So if you're paying $19 and they're both making money, think of how cheap it actually was to make!READ FULL REVIEW
This review is from: APEX AL-8250SFX 250W SFX12V Ver.3.1 Power Supply
Pros: Has input filtering...
Cons: I work at a small tech company and we use these PSU's in ISF builds. These PSU's are pathetic. They are made by Deer, a consistently low quality manufacturer. What happens with these things is the cheap Sleeve Bearing fan dies, and since the power supply doesn't have OTP (Over Temp Protection) it will continue to run until something in the unit dies, which is usually the primary transistors. They usually last a year before the bearing dies and that's with a low load Atom build that doesn't create much heat. The efficiency is HORRIBLE, it averages 67% so the more you run on this the faster the fan will dieREAD FULL REVIEW
